Abstract:

The blood supply chain, starting from the donor until the blood is used to meet transfusion demands of patients, is a multi-echelon and complex system. The perishable and lifesaving characteristics of blood products, such as red blood cells and platelets, as well as uncertainties in both supply and demand make it difficult to maintain a balance between shortage and wastage due to expiry. An effective blood supply chain should be able to meet the demand while at the same time reducing wastage and total operational cost. In order to be cost effective, the related organizations have to decide how much blood should be collected from donors, how much blood products should be produced at the blood center, and how much blood products should be distributed to hospitals or transshipped between hospitals. The objective of this dissertation is to provide these tactical and operational decisions to guide those who work in healthcare supply chain management and explore new opportunities on performance improvement for an integrated blood supply chain by optimization with aim of minimizing total cost, consideration of transshipment between hospitals, and application of a coordinated multi-product model. This dissertation presents three multi-stage stochastic models for an integrated blood supply chain to minimize total cost incurred in the collection, production, inventory, and distribution echelons under centralized control. The scope of this study focuses on modeling a supply chain of blood products in one regional blood center, several hospitals and blood collection facilities. First, we develop an integrated model for the platelet supply chain that accounts for demand uncertainty and blood age information, then we develop this model further by investigating the impact of transshipment between hospitals on cost savings, and then we propose a multi-product model that accounts for red blood cells and platelets at the same time and compare it with an uncoordinated model where the red blood cell and platelet supply chains are considered separately.

Abstract:

The cladding industry is relatively independent and complex, having contemporary features in a rapidly changing sector of the construction industry. The increasing complexity of the cladding procurement and fragmentation of the supply chain bring challenges for making informed decisions. The purpose of this research was to study the cladding design and procurement process, in particular the decision making process. It was hoped to develop an integrated decision making mechanism within the context of the cladding supply chain. Based on preliminary exploration, a conceptual model of integrated communication and decision-making (ICDM) was proposed. Within this model, an Information and Communication (I&C) Hub acts as the pivotal platform of the information supply and communication in the supply chain and is managed by an industry level third party. It provides an effective and secure approach to information exchange and collaborative decision making. A questionnaire survey was the key method of this research, while industry meetings and informal interviews were employed to provide in-depth understanding of the communication related issues in the industry. It was found that the participants of the cladding supply chain were experiencing difficulties of identifying information sources and accessing information, and that an industry level third party acting as an independent information source could be accepted by the cladding industry. Therefore, the I&C Hub gained its necessity and partial feasibility. It was also found that training opportunity for practitioners was limited and the usage of ICT had a large potential for improvement. A number of modifications on the I&C Hub and information flows within the ICDM were proposed to enhance its practicality, and the enhanced model was presented and evaluated by an industry meeting. The conceptual model can only be completely validated by real cases; therefore, this study concluded with a recommendation for testing the framework in future pilot projects.

(cont.) in the success of Lucent's turnaround and, from the patterns that emerge, a basis for a new holistic framework for designing and leveraging an integrated supply chain is offered. This framework suggests that attaining competitive advantage from supply chain capabilities lies in a firm's ability to incorporate corporate culture, leadership style, organization structure and both inter and intra tier governance methods into it's supply chain design in order to enable an integrated and extended organization where the channel expert can be identified and engaged in decision making in a natural, real-time and organic process.
Over the past three years, in response to dramatic changes in the telecommunications industry, Lucent Technologies has realigned its corporate strategy from being a provider of manufacturing excellence to one of supply chain excellence. Supported by this realignment, Lucent has recently returned to profitability after eleven consecutive losing quarters, and has posted dramatic improvements in financial, operational and customer satisfaction metrics. Lucent's new strategy is focused on leveraging its supply chain capabilities to create a new extended enterprise that is both customer and supplier intimate, and operates as a broad reaching cross-functional Supply Chain Networks (SCN) organization. Pivotal to the success of this realignment was extending the scope of Lucent's supply chain activities, both internally and externally to the company. Internally, Lucent integrated such non-traditional SCM activities as sales, product design, and margin management into its newly created SCN organization. Externally, by outsourcing virtually all of its manufacturing, and much of the associated supplier management, to Electronics Manufacturing Services (EMS) partners, Lucent became responsible for the orchestration of an extended multi-tier supply chain that integrated abilities and expertise of functional teams within Lucent and within its EMS partners, raw component suppliers and customers. In this thesis, the Supply Chain Networks transformation at Lucent is examined in the broader context of the changes that took place in Lucent's: organizational model; leadership team; corporate culture; customer and supplier relationships; operations; and market space. The change that was effected in each of these areas is reviewed for its role

Abstract:

In 2009, Roland Berger Strategy Consultants [Roland Berger Strategy Consultants, (2009). Global SCM excellence study., p.5.] reported that 40% of 234 companies had the wrong priorities in regard to efficiency vs. responsiveness. In 2014, PricewaterhouseCoopers (PwC) and American Production and Inventory Control Society (APICS) [PwC and APICS, Sustainable supply chains: Making value the priority 2014] found that 76% of 500 supply chain executives identified sustainability as an important aspect of their supply chain. The results highlight the importance of achieving consistency between customer expectations, in terms of cost and service level, and supply chain performance in today’s competitive business environment. Despite this, however, no integrated supply chain design framework exists to control majority of the important functions related to supply chain strategy, structure, process and performance. The literature review showed that simulation is rarely considered at the strategic level, but the research experiments highlighted a number of ways in which simulation tools might be useful at this level, such as exploring the impact of strategic fit and decoupling points, and assessing different supply chain network configurations and policies. This research contributes to knowledge by designing and developing a framework that integrates strategy, process and resources, and allows the use of simulation tools to consider the three dimensions of efficiency, responsiveness and sustainability concurrently during the design process. The proposed framework is validated using a hypothetical supply chain network. Simulation allows performance to be assessed under a range of scenarios. The simulation experiments showed that under the suggested policies, efficiency improved from 25.38% to 30.58% and responsiveness rose from 18.37% to 32.78%. However, they also indicated that while policies oriented towards improving responsiveness had a positive impact on sustainability, those oriented towards improving efficiency had a negative impact. The significance of the research lies in its development of a supply chain design framework that could assist companies in achieving the optimum configuration of supply chain resources, thereby helping them reduce inventory, lower costs, enhance responsiveness and improve strategic focus in terms of design, execution and capital investments.

Abstract:

Manufacturing outsourcing in the U.S. has never been stronger than it is today. Increased outsourcing has led to significant changes in the design of the retail distribution network. While the traditional distribution network had the manufacturing plants supplying goods to the retail stores directly, the off-shore manufacturing has increased the network's demand for transportation and warehousing to deliver the goods. Thus, most companies have a complex distribution network with several import and regional distribution centers (RDC). In this thesis, we study an integrated facility location and inventory allocation problem for designing a distribution network with multiple national (import) distribution centers (NDC) and retailers. The key decisions are where to locate the RDCs and how much inventory to hold at the different locations such that the total network cost is minimized under a pre-defined operational rule for the distribution of goods. In particular, the inventory cost analysis is based on the continuous review batch ordering policy and the base-stock policy. Both Type-I (probability of stock-outs) and Type-II (fill-rate) service level measures are used in the analysis. Two different models are presented in this thesis for solving the integrated facility location-inventory allocation problem. The first model, continuous approximation (CA), assumes the distribution network to be located in a continuous region and replaces the discrete store locations with a store density function. The second model is a discrete representation of the problem as a mixed integer programming problem. Both the models take a nonlinear form and solution techniques are developed using the theory of nonlinear programming and linear reformulation of nonlinear problems. The goal of the first part of the thesis is to model the problem using a modified CA approach and an iterative solution scheme is presented to solve it. The main contribution of this work lies in developing a refined CA modeling technique when the discrete data cannot be modeled by a continuous function. In addition, the numerical analysis suggests that the total network cost is significantly lower in the case of the integrated model as compared with the non-integrated model. It is also shown that the regular CA approach leads to a solution which is inferior to the solution obtained by the modified CA approach. Our analysis shows that the type of service measure used affects the network design. In the second part of the thesis, the problem is modeled as a nonlinear mixed integer program and a linear reformulation solution technique is proposed to obtain a lower bound on the original problem. Computational results are presented for small problem instances. We conclude this part of the thesis by presenting an integrated model when a base stock inventory policy is used. A drop-decomposition heuristic is proposed to solve this problem.

Abstract:

Integrated robust planning systems that cover all levels of SC hierarchy have become increasingly important. Strategic, tactical, and operational SC plans should not be generated in isolation to avoid infeasible and conflicting decisions. On the other hand, enterprise planning systems contain over millions of records that are processed in each planning iteration. In such enterprises, the ability to generate robust plans is vital to their success because such plans can save the enterprise resources that may otherwise have to be reserved for likely SC plan changes. A robust SC plan is valid in all circumstances and does not need many corrections in the case of interruption, error, or disturbance. Such a reliable plan is proactive as well as reactive. Proactivity can be achieved by forecasting the future events and taking them into account in planning. Reactivity is a matter of agility, the capability of keeping track of system behaviour and capturing alarming signals from its environment, and the ability to respond quickly to the occurrence of an unforeseen event. Modeling such a system behaviour and providing solutions after such an event is extremely important for a SC. This study focuses on integrated supply chain planning with stochastic dynamic considerations. An integrated tactical-operational model is developed and then segregated into two sub-models which are solved iteratively. A SC is a stochastic dynamic system whose state changes over time often in an unpredictable manner. As a result, the customer demand is treated as an uncertain parameter and is handled by exploiting scenario-based stochastic programming. The increase in the number of scenarios makes it difficult to obtain quick and good solutions. As such, a Branch and Fix algorithm is developed to segregate the stochastic model into isolated islands so as to make the computationally intractable problem solvable. However not all the practitioners, planners, and managers are risk neutral. Some of them may be concerned about the risky extreme scenarios. In view of this, the robust optimization approach is also adopted in this thesis. Both the solution robustness and model robustness are taken into account in the tactical model. Futhermore, the dynamic behaviour of a SC system is handled with the concept of Model Predictive Control (MPC).

Abstract:

Las tendencias del mercado han hecho que las empresas cambien su forma de hacer negocios. La Globalización ha permitido a las empresas tener la posibilidad de acceder a distintos proveedores y mercados globalmente dispersos. Actualmente para mantener un nivel competitivo, el mercadoreclama productos amigables con el medio ambiente, rápido desarrollo de nuevos productos, alta calidad y fiabilidad, entre otros. Para cumplir con tales requisitos, las empresas dependen cada vez más de su Cadena de Suministros (CS). De hecho, la competencia en el mercado ya no es únicamente entre empresas, sino entre CS. La comunidad científica es consciente de este cambio y ha dedicado esfuerzos a la concepción de estrategias para el modelado y optimización de CS. Asimismo, la industria química Europea reconoce necesaria la mejora de la Gestión de la Cadena de Suministros (GCS) para mantenerse competitiva en un mercado global. La GCS trata de maximizar los retornos financieros sincronizando los flujos de materiales, información y efectivo existentes entre las distintas entidades interconectadas con el objetivo de proveer un producto al mercado. Recientemente, también se reconoce la necesidad de una Gestión Integrada de la CS (GICS), la cual consiste en la sincronización de otras funciones del negocio y de diferentes niveles de decisión. El actual entorno dinámico de los negocios y de las propias operaciones hacen difícil la coordinación de las actividades de la CS. Por tanto, es importante que los objetivos y planes sean desarrollados considerando explícitamente la incertidumbre del mercado y de las propias tareas de fabricación y que sean revisados periódicamente. El propósito de esta tesis es contribuir al desarrollo de estrategias para la GICS. La tesis contempla CS centralizadas, es decir, se considera que existe una entidad central que es capaz de controlar las actividades de toda la CS. Después de una revisión de conceptos y de las estrategias existentes para abordar la GICS, la tesis se enfoca en el desarrollo de modelos queincluyen decisiones de diferentes funcionalidades del negocio. Esta parte explora cómo mejorar el comportamiento de la CS si conjuntamente con la gestión estratégica de la CS se integran decisiones asociadas con finanzas, marketing y desarrollo de nuevos productos. A continuación la tesis se dedica a temas puramente relacionados con la gestión estratégica y táctica de las operaciones de la CS. Se investiga cómo obtener una representación más apropiada de los procesos productivos a nivel de CS. En esta parte se considera también el diseño de CS considerando su impacto ambiental asociado. La cuarta parte está dedicada a la consideración de la incertidumbre. Para ello se propone un control predictivo que incorpora como algoritmo de control un modelo estocástico. Se muestra como las incidencias pueden resolverse de mejor manera cuando se tiene en cuenta una visión completa de la CS en la búsqueda de posibles soluciones. Además, se desarrolla una extensión del método para programación de operaciones (PO) S-graph para abordar problemas con incertidumbre. Esta propuesta posee la particularidad que el tamaño del espacio de búsqueda no crece con el número de escenarios considerados. Dicha característica permite reducir los tiempos de solución, lo cual es uno de los desafíos en esta área. La última contribución está relacionada con la integración de los niveles de decisión. Se muestra como la capacidad es el factor clave para llevar a cabo esta integración. Se examinan las implicaciones de considerar la PO cuando se diseña una CS. En esta parte se hace hincapié en la errónea sobreestimación de la capacidad que se obtiene cuando la PO no es incluida en el diseño de CS. Aún más, se demuestra como la capacidad permite la integración del módulo de control de bajo nivel con la CS por medio de la formulación de la PO. Dicha integración permite actualizar la capacidad real y resolver adecuadamente interrupciones y fallos en los equipos.
Market trends have made enterprises change the way of doing business. Globalization makes accessible a wide range of globally dispersed potential suppliers and customers. For competitive customer service now the market demands environmentally friendly products, rapid development of newproducts, high quality and reliability, among others. In order to fulfill such requirements firms depend more and more on their supply chains (SC). Indeed, nowadays competition is not longer among individual firms, but among SCs. The process system engineering community has been conscious of this shift and has thus devoted research efforts on devising SC and enterprise-wide modeling and optimization strategies. Likewise, from another stand point, the European chemical industry has realized the necessity of SC improvement in order to remain competitive in the global market. Supply Chain Management (SCM) is intended to maximize financial returns by synchronizing material, cash and information flows across interconnected entities that seek to provide products to consumers. Lately, it has been recognized the necessity for integrated SCM solutions which incorporate and synchronize decisions from several business functions and different hierarchical levels. Current changing and uncertain marketenvironment and internal business concerns make it even more difficult to synchronize all the SC activities. Hence, it would be desirable that SC objectives and plans were developed considering market and internal operations uncertainty explicitly, revised periodically and eventually modified following the uncertainty disclosure. The aim of this thesis is to contribute to the centralized integrated SCM. The centralized approach to SCM considers that there exists a central entity that it is able to control the activities of the whole business. After an overview of SCM and analysis of existing approaches, the second part of this thesis is focused on the development of models which consider the variety of business functionalities. This part explores how business performance can be improved by integrating strategic SCM with financial, marketing and product development planning. The following section is devoted to topics related to pure strategic and tactical SC operations. It is investigated how a more appropriate representation of production processes can be achieved at the SC level. This part is also concerned with the environmentally conscious design of SCs. The fourth part is focused on uncertainty considerations. A model predictive control whose control algorithm is a stochastic formulation is proposed to face uncertainty and dynamics in SCM. Here, it is shown how incidences can be better resolved by approaching them from a SC perspective. This part also presents a novel graph based approach to deal with scheduling under exogenous uncertainty. The S-graph framework is enhanced to address a two stage stochastic scheduling considering demand as uncertain. One of the advantages of this approach is that the search space does not increasewith the number of considered scenarios. Such a feature reduces the computational cost required to solve this kind of problems which is one of the major challenges in this field, thus constituting a robust alternative to existing schedulers to become eventually the best option in integrated SCM. The last contribution concerns the integration of hierarchical decision levels. The fifth part examines the implications of considering scheduling decisions when designing a SC network. It is shown how capacity is the core factor that allows the integration of hierarchical levels. This part emphasizes that an optimistic performance, due to capacity overestimation, is obtained if scheduling is not consider into the SC design formulation. Moreover, it is demonstrated how capacity permits low level supervisory control integration. Such integration allows updating SC capacity and adequately resolving equipment disruptions or breakdowns.

Abstract:

Lack of visibility of the assets in a product supply chain compromises attempts to optimise supply chain management. Increasing the visibility of these assets presents a relatively unexplored frontier in operations and supply where organisations can create competitive advantage through the opportunities asset visibility offer. This research aims at investigating the key capabilities of asset visibility specifically those associated with returnable transport assets that travel across supply chains carrying material and products e.g. cages, boxes, trays, trolleys and pallet bins. In addition, how these capabilities may influence supply chain visibility and firm performance in a way that might lead to sustainable competitive advantage is examined. To achieve these objectives, the research develops a two-stage model that is theoretically grounded in the extended resource-based view. Philosophically, the research adopts a critical realist approach using abductive logic. Methodologically, a sequential exploratory strategy for data collection is implemented. A qualitative, indepth site-based case study supported by field expert interviews was conducted as a pilot study. The pilot study findings refined the initial conceptual model derived from literature and informed the next stage of the research. The quantitative phase focused on refining the factors constituting asset visibility capabilities and then testing the relationship between these capabilities and supply chain visibility, performance and sustainable competitive advantage. Key findings are that asset visibility capabilities are shaped through three key capabilities: (1) an asset management capability formed by both core technological aspects related to tracking and tracing technology, and non-technological ones focusing on logistic-related capability; (2) a complementary technological capability comprising of IT infrastructure for supply chain integration; and (3) a complementary nontechnological capability represented through three sub-capabilities: (a) supply chain process integration; (b) focal firm-3PL relational orientation; and (c) internal firm integration. The research findings prove a positive relationship between asset visibility capabilities and supply chain visibility. In addition, a positive relationship between these capabilities and sustainable competitive advantage through the mediated effect of supply chain visibility and firm performance, is confirmed.

This thesis is based on an internship at Honeywell Aerospace's Integrated Supply Chain (ISC) Leadership division. This work focuses on the role and use of analytical cost models in the strategy development process. The scope of ISC strategic decisions encompasses Honeywell Aerospace's global footprint of external and internal suppliers, and includes insourcing, outsourcing, transition and consolidation activities. The current practice within Honeywell Aerospace is to construct a Transition, Migration, and Integration (TMI) model which calculates the net present benefit associated with a specific transition's spending and savings. This model is the primary tool for strategic plan development. This work looks at the use of the TMI model for strategic planning with the intent of addressing concerns related to the model's complexity and accuracy. This work also develops the framework for estimating a confidence range within the TMI model to provide better visibility to the potential range of financial outcome. An additional tool used in the development of the strategic plan is the Landed Cost model.
(cont.) The Landed Cost model is used to calculate the steady state total cost associated with a particular supply chain. Historically within Honeywell Aerospace ISC planning, the Landed Cost model has been used to much less of a degree than the TMI model. This work develops the role of the Landed Cost model and establishes a framework for estimating labor, logistics, inventory, and tax costs associated with manufacturing products in a variety of global regions. While this work focuses on developing analytical tools, developments and recommendations are provided in the context of the overall strategic decision process. Examples are provided to highlight the major cost drivers associated with a particular transitional activity or supply chain design. Improving the analytical component of the decision process allows ISC Leadership to more accurately and effectively identify tactics for improving operational efficiency and identify potential growth opportunities in emerging regions.

Blockchain technology is a peer-to-peer infrastructure based on distributed databases and smart contracts as the business logic. The distributed ledger technology eliminates the need for intermediaries disrupting the ownership model. It can have a tremendous impact on cross-organizational process automation when combined with other innovative technologies such as machine learning and additive manufacturing. Over the past few years as the blockchain technology concept has increasingly attracted many industries. The logistics and supply chain management industry have also realized its potential applications in enabling transparency, efficient information sharing, and food safety. Several companies have identified possible use cases that could benefit from blockchain over existing IT solutions. Thesis report provides an overview of current state of blockchain adoption, its technology architecture, review of how blockchain technology and smart contract works, and the benefits and challenges involved. Further, provided a deep dive into the problem of food safety, and the food supply chain and logistics ecosystem drivers. Highlighted, the current use cases of blockchain technology in supply chain and logistics along with critical success factors that companies consider essential for blockchain technology adoption. In the interviews conducted, digital innovators and senior executives are fairly positive about the blockchain technology and its benefits. However, factors such as under-developed ecosystem, lack of governance model and regulatory uncertainty impact its adoption. The proposed framework consists of a hybrid architecture of private and public blockchains, enabling immutable record sharing and monitoring while maintaining selective data privacy.

Abstract:

Cette thèse contribue au déploiement de l’infrastructure liée à l’énergie renouvelable qu’est l’hydrogène, en proposant de nouvelles stratégies basées sur des approches d’optimisation. Un état de l’art sur la conception de la chaîne logistique de l’hydrogène est préalablement réalisé, et permet d’identifier dans la littérature deux perspectives de recherche. La première concerne la couverture de la chaîne logistique globale, qui n’est pas assurée, d’une part en amont au niveau de la localisation des fournisseurs de matières premières et de l’approvisionnement des centres de production (aspect transport), d’autre part en aval au niveau de la localisation des points de distribution (stations-service) et de leur approvisionnement (transport). Pour intégrer ces composantes, un nouveau modèle de planification est élaboré. Il fusionne les modèles classiques, plus précisément un modèle de HSCND (Hydrogen Supply Chain Network Design) au niveau central, c’est-à-dire au niveau de la production et du stockage, et un modèle de HSRP (Hydrogen Refueling Station Planning) en bout de chaîne, qui considère la distribution. Ce nouveau modèle intègre également la prise en compte des sources d’approvisionnement. Il est exprimé sous forme d’un programme linéaire en nombres entiers mixtes, avec pour objectif la minimisation du coût de l’hydrogène à la pompe (LCOH). Son intérêt est validé par une étude de cas représentant la Franche-Comté en France.La seconde voie explorée est l’intégration des niveaux de décision stratégique et tactique. Il s’agit d’optimiser simultanément la localisation des stations-service et des tournées de ravitaillement de ces stations, en considérant comme actées les décisions prises précédemment depuis les sources d’approvisionnement jusqu’aux centres de production en hydrogène. L’objectif est de maximiser la capture du flux de demande, tout en minimisant le coût quotidien total. Deux algorithmes approchés sont développés pour résoudre ce problème, l’un basé sur une recherche adaptative de grand voisinage, l’autre sur un algorithme génétique. Le modèle et les algorithmes proposés sont appliqués à la région Bourgogne Franche-Comté en France
This thesis contributes to the deployment of the hydrogen infrastructures by proposing new strategies based on optimization approaches. A state of the art on the design of the hydrogen supply chain has been previously carried out, and allows to identify in the literature two research perspectives.The first one concerns the coverage of the entire supply chain, on the one hand upstream at the level of the location of raw material suppliers and the supply of production centres (transport aspect), and on the other hand downstream at the level of the location of distribution points (refueling stations) and their supply (transport). To integrate these components, a new planning model is developed. It merges the classical models, more precisely an HSCND (Hydrogen Supply Chain Network Design) model at the central level, i.e. at the level of production and storage, and an HSRP (Hydrogen Refueling Station Planning) model at the end of the chain, which considers distribution. This new model also integrates the consideration of supply sources. It is expressed as a mixed number integer linear program, with the objective of minimizing the least cost of hydrogen (LCOH). Its interest is validated by a case study representing Franche-Comté in France.The second research area explored is the integration of the strategic and tactical decision-making levels. The aim is to simultaneously optimize the location of refueling stations and the routes to supply these stations, by considering as actuated the decisions previously taken from the supply sources to the hydrogen production centers. The objective is to maximize the refueling demand flow captured, while minimizing the total daily cost. Two metaheuristic algorithms are developed to solve this problem, one based on an adaptive large neighbourhood search, the other on a genetic algorithm. The proposed model and algorithms are applied to the Bourgogne-Franche-Comté region in France

Abstract:

When two logistical decisions of the supply chain namely location (a strategic decision) and routing (a tactical decision) are combined, the location- routing problem (LRP) is formed. LRP deals with simultaneously locating one or more supply facility among a set (or sets) of potential facilities and assigning customers to the selected facility (or facilities). To further improve the operation of the supply chain process, it is presented in this dissertation to integrate inventory control, as another tactical decision, with the LRP. The presented model considers the multi-product network under the fixed- interval inventory policy where stochastic demands represent the customers' requirements. Moreover, the third party logistics allows excess space for selected warehouses if needed. A two phase heuristic simulated annealing is presented as solution methodology. Test problems are designed and solved by the developed algorithm to evaluate the presented solution approach. Results show that the integrated decision leads to saving on the network cost. Furthermore, two case studies are discussed to show how the presented model can be used in practice

Abstract:

The supply chain management discipline suggests that information sharing is paramount when attempting to achieve cost reductions and quality improvements. In many cases, the traditional accounting data used to support strategic decisions reflect inaccurate supply chain costs. This research explores the applications of managerial costing techniques, and how they can be used to improve the decision making capabilities of firms in the aerospace and transportation industries. The methodology used to address the research questions consisted of a hybrid of the grounded theory and multiple-case study methods. The objective of this research was to present the antecedents and barriers associated with implementing supply chain costing, and the impact that costing approaches have on strategic decision making. The research identifies a theoretical model that can be used to explain the relationships and themes associated with supply chain costing and strategic decision making. Evidence suggests that there is some movement to implement managerial accounting techniques within these two industries to capture supply chain costing information. However, the reliance on traditional financial accounting suggests that the overarching principles of supply chain management and information sharing amongst of partner firms has yet to be realized.

Abstract:

This work focuses on the need for new knowledge to allow hierarchical multi-project management to be conducted in the construction industry, which is characterised by high uncertainty, fragmentation, complex decisions, dynamic changes and long-distance communication. A dynamic integrated project management approach is required at strategic, tactical and operational levels in order to achieve adaptability. The work sees the multi-project planning and control problem in the context of supply chain management at main contractor companies. A portfolio manager must select and prioritise the projects, bid and negotiate with a wide range of clients, while project managers are dealing with subcontractors, suppliers, etc whose relationships and collaborations are critical to the optimisation of schedules in which time, cost and safety (etc) criteria must be achieved. Literature review and case studies were used to investigate existing approaches to hierarchical multi-project management, to identify the relationships and interactions between the parties concerned, and to investigate the possibilities for integration. A system framework was developed using a multi-agent-system architecture and utilising procedures adapted from literature to deal with short, medium and long-term planning. The framework is based on in-depth case study and integrates time-cost trade-off for project optimisation with multi-attribute utility theory to facilitate project scheduling, subcontractor selection and bid negotiation at the single project level. In addition, at the enterprise level, key performance indicator rule models are devised to align enterprise supply chain configuration (strategic decision) with bid selection and bid preparation/negotiation (tactical decision) and project supply chain selection (operational decision). Across the hierarchical framework the required quantitative and qualitative methods are integrated for project scheduling, risk assessment and subcontractor evaluation. Thus, experience sharing and knowledge management facilitate project planning across the scattered construction sites. The mathematical aspects were verified using real data from in-depth case study and a test case. The correctness, usefulness and applicability of the framework for users was assessed by creating a prototype Multi Agent System-Decision Support System (MAS-DSS) which was evaluated empirically with four case studies in national, international, large and small companies. The positive feedback from these cases indicates strong acceptance of the framework by experienced practitioners. It provides an original contribution to the literature on planning and supply chain management by integrating a practical solution for the dynamic and uncertain complex multi-project environment of the construction industry.

Abstract:

An integrated simulation, learning, and game-theoretic framework is proposed to address the dynamics of supply chain competition. The proposed framework is composed of 1) simulation-based game platform, 2) game solving and analysis module, and 3) multi-agent reinforcement learning module. The simulation-based game platform supports multi-paradigm modeling, such as agent-based modeling, discrete-event simulation, and system dynamics modeling. The game solving and analysis module is designed to include various parts including strategy refinement, data sampling, game solving, equilibrium conditions, solution evaluation, as well as comparative statistics under varying parameter values. The learning module facilitates the decision making of each supply chain competitor under the stochastic and uncertain environments considering different learning strategies. The proposed integrated framework is illustrated for a supply chain system under the newsvendor problem setting in several phases. At phase 1, an extended newsvendor competition considering both the product sale price and service level under an uncertain demand is studied. Assuming that each retailer has the full knowledge of the other retailer's decision space and profit function, we derived the existence and uniqueness conditions of a pure strategy Nash equilibrium with respect to the price and service dominance under additive and multiplicative demand forms. Furthermore, we compared the bounds and obtained various managerial insights. At phase 2, to extend the number of decision variables and enrich the payoff function of the problem considered at phase 1, a hybrid simulation-based framework involving systems dynamics and agent-based modeling is presented, followed by a novel game solving procedure, where the procedural components include strategy refinement, data sampling, gaming solving, and performance evaluation. Various numerical analyses based on the proposed procedure are presented, such as equilibrium accuracy, quality, and asymptotic/marginal stability. At phase 3, multi-agent reinforcement learning technique is employed for the competition scenarios under a partial/incomplete information setting, where each retailer can only observe the opponent' behaviors and adapt to them. Under such a setting, we studied different learning policies and learning rates with different decay patterns between the two competitors. Furthermore, the convergence issues are discussed as well. Finally, the best learning strategies under different problem scenarios are devised.

Abstract:

This thesis aims to explore the strategic roles of integrated logistics and supply chain management and global sourcing strategy for firms' performance, and to examine the direct and indirect relationships between integrated logistics and supply chain management, logistics performance, global sourcing performance, and further sustainable competitive advantage. This thesis adopts resource based theory to explore the relationships between a firm's specific capability and its performance and employs structural equation modelling in order to rigorously test the validation of the measurement models and examine the relationships between the construct variables. The data used were collected by postal questionnaire survey from logistics managers of 195 firms from the automobile and electronics industries based in Korea. The empirical research shows that (1) there exists a significant positive relationship between information & planning formality and strategic planning (2) strategic planning has a significant positive influence upon integrated logistics and SCM capability (3) internal integration & customer relationship has a significant effect on logistics performance (4) supplier integration and logistics integration & customer service exert significant impacts upon global sourcing performance (5) supplier integration has a significant effect on the firm's competitive market position (6) a superior logistics capability exerts a significant impact upon global sourcing performance and sustainable competitive advantage (7) global sourcing capability has a significant influence on sustainable competitive advantage and competitive position in the market and (8) competitive position in the market is significantly predicted by sustainable competitive advantage. In addition, this research presents many significant indirect effects between the constructs. Overall, this thesis suggests that a firm should develop an integrated logistics and SCM capability in balance and make efforts to build superior logistics and/or global sourcing capabilities in order to effectively obtain and/or reinforce its competitive market position and long-term survival and success.

Supply chains are critical to delivering components and products safely, affordably, and securely. However, these complex networks of suppliers, manufacturers, and customers are vulnerable to internal and external disruptions and subject to exploitation. This can result in adverse impacts to the system and inhibit value delivery. This thesis proposes a generic electronics supply chain model that can guide a user through different vulnerability assessment techniques and reveal information regarding system vulnerabilities as well as opportunities for decision-makers to intervene. The model draws upon a previously-developed Cause-Effect Mapping (CEM) analytic technique and assists with making decisions affecting complex systems, including those operating in resource-constrained environments. Elements of System Security Engineering (SSE) and Trusted Systems and Networks (TSN) analysis are taken into consideration, and leading indicators are utilized to provide a greater understanding of security concerns and impacts to a supply chain focusing on electronics for the defense industry. The model, adaptable to a diversity of systems and capable of recognizing non-obvious sources of vulnerability, can be used by systems engineers to provide a holistic view of a complex supply chain. The model facilitates the communication of information regarding supply chain vulnerabilities to decision-makers and other individuals.

Blockchain is a distributed ledger technology that records exchanges of value between parties securely, permanently, and in an easily verifiable manner. It is the technology underlying cryptocurrencies such as Bitcoin and Ethereum. Although initially used for financial transactions, blockchain's applications extend beyond finance and can impact a wide variety of industries. One such application is in supply chain management. With multiple stakeholders and business transactions, supply chains are inherently complex. Many challenges exist, including the lack of transparency and traceability, difficulty in managing risks and disruptions, and the need to build trust and reputation. Blockchain technology ushers in the potential to solve these challenges through the use of smart contracts. Smart contracts are digital agreements between transacting parties that are written in computer code and deployed to the blockchain, where they will self-execute when predetermined conditions are met. They reduce complexity in a supply chain through automated verification and execution of the multiple business transactions involved. A decentralized, immutable record also ensures all stakeholders have equal access to information and helps build trust. Smart contracts improve the transparency, traceability and efficiency of a supply chain, allowing it to be more agile while strengthening relationships among stakeholders. In this thesis, I create a proof-of-concept to explore the application of smart contracts in supply chain management. The proof-of-concept consists of three smart contracts, coded in Solidity, that can be integrated to determine the provenance of goods, track the chain of custody as goods flow through a supply chain, automatically execute payment upon fulfillment of criteria, and maintain an open database of stakeholders with a score indicating their reputation. I validate the proof-of-concept using the Ethereum platform, which was specially conceived for smart contract and decentralized application development. Preliminary testing shows that the contracts are able to interact with one another and execute their functions as intended. Further testing is necessary to evaluate the performance of the contracts on the live Ethereum network, and integration with smart sensors should be explored to create a more viable real-world solution.

Abstract:

Problem – Companies and supply chains, such as those in the grocery industry, continuously face stricter requirements in the form of customer satisfaction, quality, profit margins, as well as information sharing in order to stay competitive. One specific technology that may be used in dealing with increasing competitive demands is the radio frequency identification (RFID) technology. A wide body of research recognizes the positive impacts from RFID, yet even so, doubts and uncertainty have been present among different supply chain members in industries striving to put the RFID technology to use. Nevertheless, many actors in the Norwegian grocery industry are replacing traditional wood pallets with plastic pallets, and these pallets are integrated with RFID tags. Purpose – The purpose of this thesis is to investigate how plastic pallets with integrated RFID tags can contribute to improve supply chain efficiency in the grocery industry. Also, the managerial perception on the pallets and their accompanying technology will be compared to the existing literature, to identify if the managerial opinion supports the literature, and if not, where the gaps exist. Method – The thesis combines an exploratory and an explanatory qualitative study of the managerial perception of RFID pallets in the Norwegian grocery industry, and investigates whether the perception supports the literature. The empirical material is gathered through telephone interviews with logistics and warehouse managers in the various companies. Conclusions – Physical implications: The managerial perceptions’ support towards the addressed implications of the reviewed literature is mixed. RFID pallets improve automatic operation processes through reduction in downtime and eases physical handling of pallets. Additionally, sorting of pallets becomes less labor demanding. Regarding holding of goods, the managerial perceptions do not seem to view RFID pallets as an important factor for efficiency improvement. Information related/RFID aspects’ implications: The managerial perceptions in these concerns were based on plans and thoughts, since the technology had not been put to use. There is a difference in producers’ and wholesalers’ perception of whether efficiency in receiving of goods can be improved through utilizing RFID pallets. Concerning dispatching of shipments, the managerial perceptions support the literature in that information-related activities can be automated, and thus improve efficiency and reduce risk of human errors. In regards to information sharing, the managerial perception supports the literature, but highlights that the information’s nature determines whether sharing is considered. Further research could include the retail store level to get a more complete supply chain picture, and also apply the research methods to a larger area in order to investigate the transferability to other industries and countries.

Abstract:

Supply chain management has been recently introduced to address the integration of organizational functions ranging from the ordering and receipt of raw materials throughout the manufacturing processes, to the distribution and delivery of products to the customer. Its application demonstrates that this idea enables organizations to achieve higher quality products, better customer service, and lower inventory cost. In order to achieve high performance, supply chain functions must operate in an integrated and coordinated manner. Several challenging problems associated with integrated supply chain design are: (1) how to model and coordinate the supply chain business processes, specifically in the area of supply chain workflows; (2) how to analyze the performance of an integrated supply chain network so that optimization techniques can be employed to improve customer service and reduce inventory cost; and (3) how to evaluate dynamic supply chain networks and obtain a comprehensive understanding of decision-making issues related to supply network configurations. These problems are most representative in the supply chain theory's research and applications. There are three major objectives for this research. The first objective is to develop viable modeling methodologies and analyzing algorithms for supply chain business processes so that the logic properties of supply chain process models can be analyzed and verified. This problem has not been studied in integrated supply chain literature to date. To facilitate the modeling and verification analysis of supply chain workflows, an object-oriented Petri nets based modular modeling and analyzing approach is presented. The proposed, structured, process-modeling algorithm provides an effective way to design structured supply chain business processes. The second objective is to develop a network of inventory-queue models for the performance analysis and optimization of an integrated supply network with inventory control at all sites. An inventory-queue is a queueing model that incorporates an inventory replenishment policy for the output store. This dissertation extends the previous work done on the supply network model with base-stock control and service requirements. Instead of one-for-one base stock policy, batch-ordering policy and lot-sizing problems are considered. To determine the replenishment lead times of items at the stores, a fixed-batch target-level production authorization mechanism is employed to explicitly obtain performance measures of the supply chain queueing model. The validity of the proposed model is illustrated by comparing the results from the analytical performance evaluation model and those obtained from the simulation study. The third objective is to develop simulation models for understanding decision-making issues of the supply chain network configuration in an integrated environment. Simulation studies investigate multi-echelon distribution systems with installation stock reorder policy and echelon stock reorder policy. The results show that, depending on the structure of multi-echelon distribution systems, either echelon stock or installation stock policy may be advantageous. This dissertation presents a new transshipment policy, called "alternate transshipment policy," to improve supply chain performance. In an integrated supply chain network that considers both the distribution function and the manufacturing function, the impacts of component commonality on network performance are also evaluated. The results of analysis-of-variance and Tukey's tests reveal that there is a significant difference in performance measures, such as delivery time and order fill rates, when comparing an integrated supply chain with higher component commonality to an integrated supply chain with lower component commonality. Several supply chain network examples are employed to substantiate the effectiveness of the proposed methodologies and algorithms.

Abstract:

A natureza incerta e os altos incentivos econômicos do negócio de refino são forças motrizes para melhorias nos processos de planejamento das refinarias. Decisões tomadas na cadeia do petróleo diferem principalmente na gama de atividades (integração espacial) e no horizonte de planejamento (integração temporal). O objetivo desta tese é abordar o problema da integração da cadeia do petróleo sob incerteza em diferentes níveis de decisão. Modelos de programação matemática tático e operacional são propostos. O modelo tático maximiza o lucro esperado da cadeia de suprimentos e aloca metas de produção para as refinarias considerando restrições logísticas. O modelo operacional maximiza o lucro esperado de cada refinaria determinando a quantidade de material processada por unidade de processo em um dado período. Ambos os modelos são lineares estocásticos de dois estágios, onde a incerteza é incorporada nos parâmetros dominantes de cada nível (preço e demanda no nível tático e suprimento de petróleo e capacidade das unidades no nível operacional). A integração espacial é discutida no nível tático (considerando a cadeia de suprimentos), enquanto a integração temporal é discutida na interação entre os dois níveis. Duas abordagens de integração temporal são consideradas: hierárquica, onde o fluxo de informações é somente do modelo tático para o operacional, e iterativa, onde há retorno do nível operacional para o tático. Um estudo de escala industrial foi conduzido para demonstrar os benefícios da integração em ambiente estocástico. Resultados são oferecidos no contexto de um estudo usando dados da indústria brasileira do petróleo para demonstrar a eficácia das abordagens propostas.
The uncertain nature and high economic incentives of the refining business are driving forces for improvements in the refinery planning process. Decisions made at the oil chain differ mainly in the range of activities (spatial integration) and planning horizon (temporal integration). This thesis purpose is to address the problem of the oil chain integration under uncertainty at different decision levels. Tactical and operational mathematical programming models are proposed. The tactical model maximizes the expected profit of the supply chain and allocates the production targets to refineries taking logistics constraints into account. The operational model maximizes the expected profit of each refinery determining the amount of material that is processed at each process unit in a given period. Both models are two-stage stochastic linear programs where uncertainty is incorporated in the dominant random parameters at each level (price and demand at the tactical level and oil supply and process capacity unit at the operational level).Spatial integration is discussed at the tactical level (considering supply chain), whereas the temporal integration is discussed in the interaction between the two levels. Two temporal integration approaches are considered: hierarchical, where the flow of information is only from the tactical to the operational model, and iterative, where there is feedback from the tactical to the operational model. An industrial scale study was conducted to discuss the benefits of integration in a stochastic environment. Results are offered in the context of a study using data from the Brazilian oil industry to demonstrate the effectiveness of the proposed approaches.

Abstract:

In today's competitive market place, all the components of a supply chain must be well coordinated to achieve economic and service goals. This dissertation is devoted to the modeling, analysis, and development of solution approaches for some logistics problems with emphasis on coordination of various supply chain components and decisions. Specifically, we have addressed four problems in this domain that span various decision levels. The first problem deals with integrated production and shipping scheduling for a single manufacturer and multiple customers. We develop an optimum-seeking algorithm and a fast heuristic, both of which exploit structural properties of the problem. The second problem is a joint production and delivery scheduling problem in which a single vendor supplies goods to a single buyer over a finite horizon. We model this multi-period problem by using a dynamic programming framework and develop an effective Lagrange multiplier method for the solution of the single-period problem, which is then used to solve the multi-period problem. We show that the optimal shipments in each period follow a pattern of geometric-then-equal sizes except for the last shipment, which may be of a larger size. We also show that an optimal solution for the infinite horizon problem can be derived as a special case of our finite horizon approach. In addition, we propose two fast heuristic methods, which, as we show, can obtain almost optimal solutions. We also address the design and logistics operation of biomass feedstock supply chain. To that end, we consider two problems. The first of these problems arises in the context of delivering biomass sorghum to a biorefinery. We propose multi-period, mixed integer linear programming models, which prescribe the strategic and tactical logistics decisions. Our aim is to investigate different logistical configurations available in a sorghum biomass feedstock logistics system. The second of these problems further allows sharing of loadout equipment among storage facilities. We develop an efficient Benders decomposition-based algorithm, and also, two heuristic methods that are capable of effectively solving large-scale instances. We also show the advantage of using mobile equipment.

Abstract:

Optimizing supply chain is the most successful key for manufacturing systems to be competitive. Supply chain (SC) has gotten intensive research works at all levels: strategic, tactical, and operational levels. These levels, in some researches, have integrated with each other or integrated with other planning issues such as inventory. Optimizing inventory location and level of safety stock at all supply chain partners is essential in high competitive markets to manage uncertain demand and service level. Many works have been developed to optimize the location of safety stock along supply chain, which is important for fast response to fluctuation in demand. However, most of these studies focus on the design stage of a supply chain. Because demand at different horizon times may vary according to different reasons such as the entry of different competitors on market or seasonal demand, safety stock should be optimized accordingly. At the planning (tactical) level, safety stock can be controlled according to each planning horizon to satisfy customer demand at lower cost instead of being fixed by a decision taken at the strategic level. On the other hand, most studies that consider safety stock optimization are tied to a specific system structure such as serial, assembly, or distribution structure. This research focuses on formulating two different models. First, a multi- echelon safety stock optimization (MESSO) model for general supply chain topology is formulated. Then, it is converted into a robust form (RMESSO) which considers all possible fluctuation in demand and gives a solution that is valid under any circumstances. Second, the safety stock optimization model is integrated with tactical supply chain planning (SCP) for manufacturing systems. The integrated model is a multi-objective mixed integer non-linear programming (MINLP) model. This model aims to minimize the total cost and total time. A case study for each model is provided and the numerical results are analyzed.

As Boston Scientific's supply chain becomes more versatile in mixing their supply networks across divisions, there is new opportunity to re-optimize product flow downstream of manufacturing based on unique product attributes and network capabilities instead of solely legacy divisional flow. The current organizational structure, methods, and systems prompts product flow to be optimized within functional silos. However, there are no current methods or tools that readily enable management to evaluate the total system in an integrative manner or with respect to specific product attributes. This project aims to improve BSC's ability to determine optimal product flow by introducing a tool that optimizes across the downstream supply chain via an integrative perspective that accounts for product and network attributes.
The integration involves the major cost activities, such as freight, handling, and inventory costs, or what can be termed the total "Cost-to-Deliver" product from a manufacturing facility to end customers. The proposed optimization framework includes the inter-dependencies of cost drivers across the supply chain that are typically missed when solving in functional silos. We develop a decision support tool to determine optimal product flow across the various nodes within the downstream supply chain (manufacturing, sterilization, and multiple tiers of distribution centers) over a single period horizon that can be extend to multi-periods through a present value approach. This tool enables the decision maker to compare directly the trade-offs between two different constrained flows, as well as vary product parameters within this scenario comparison to uncover ideal product segmentation with respect to flow decisions.
To demonstrate the value for the tool, we used it to segment products with respect to the choice of transportation mode on a freight lane. We find that changing the standard transportation mode for several current products would yield five-year net present value savings of 10-35% of their current annual cost-to-deliver. Ultimately the insights gained, and framework leveraged, are relevant to other industries with multinodal supply chains with high-mix products and not just constrained to the Medical Device industry.

With the growing development of the panel industry and the automotive electronics, competition of the entire panel industry has increased significantly in the supply chain market. Therefore, decreasing production costs and cost of raw materials have been the focus for business expansion. The entire panel supply chain can achieve integration through the vertical integration of the upstream, midstream and downstream companies. It allows the companies to achieve higher profits and avoid necessary costs due to uncoordinated decision making by the production and marketing departments. Even though Polarizer account to about 10% of the cost of TFT-LCD, the large-scale panel companies in Taiwan and South Korea have made an effort to apply vertical integration model. This is due to the high profits and high cost-effectiveness. The integration model of the midstream and downstream companies have also done well, and this is the motivation for our study. The vertical integration model is studied and analyzed using a case example from the polarizer company in Taiwan. The strategy of the polarizer vertically integrated supply chain is discussed using the Porter’s five forces analysis and the SWOT analysis. The five forces analysis include: the competitions between the existing competitors; the threats from the potential entrants; the threats from the substitutes; bargaining power of buyers, and the bargaining power of suppliers. In the SWOT analysis, the strategy is based on the strength and weakness of companies’ internal situation, and the opportunities and threat from the external environment.

In the Internet Era of the 21st century, we have gradually progressed toward e-commerce, which can strengthen the competitiveness of companies and provide individualized services for customers. It can change the current business model from production-centered to customer-centered. Thus, product quality and cost are no longer the main competitive advantages, with computerization, handling of Just-in-time taking their place. Information has brought together all aspects of the production cycle uniting development, research, sales, purchase, sales service all the wag to finance into a supply chain embracing information flow, flow of goods and business, and work flow. This has strengthened management of transport and decreased overhead, increased quality, decreased sales-to-service time and increased reaction times to create an overall rise in competitiveness. This research focuses on the formulation of the supply chain mentioned above utilizing multi-leveled IDEF0 structure for analysis not only to create a integrated model structure of information system that can handle various work model systems but also can explain the organization of how activities in a system come together in order to understand the nature of information between enterprises. In availing ourselves of this information flow model to grasp an understanding of demand we have to build an enterprise that decreases the cost of doing business and increases competitiveness. Further, this research discusses how to manage the supply chain including the problem of confronting the supply chain, the transformation of the supply chain environment, applied categorization in the supply chain management and effective realization of supply chain management. We also hope that through this discussion we will understand more deeply models of the construct of supply chain information systems to bring about more concepts and ideas.

Developments in global competition, technology innovation, and transportation systems mean that people can now purchase a greater variety of products at lower prices much more easily. However, this makes it difficult for a retailer to forecast demand and to place orders accordingly. As a result, many retailers request that manufacturers honor the return of unsold goods to avoid the risks that are inherent in volatile demand. Early models of such return arrangements were characterized by an understanding that a retailer might request a manufacturer to buy back unsold goods. In turn, the manufacturer, to compensate for his or her increased costs, would charge higher wholesale prices. However, these studies have either focused on optimization from the retailer’s perspective only, or ignored the fact that the manufacturer might have no incentive to accept returns. This dissertation tries to overcome these drawbacks and extend the traditional return contracts to following three topics: (1) Take account of option premium to improve supply chain decentralized problem. (2) Take account of a menu of discount-return combinations to maintain channel efficiency. (3) Take account of the self-interest of both the retailer and the manufacturer, and demonstrates that a quantity discount scheme should provide the manufacturer with incentive to accept returns. For each topic, the model will be established and the numerical example to illustrate the scheme will be given.

Supply chain management is a method that integrates suppliers, manufacturers and retailers together effectively. Due to current severe global business competition, supply chain management becomes a necessary business model. The ultimate goal of a business is to effectively reduce cost and increase profit, which was an unachievable idea for traditional business management. To keep up with the world changes, businesses are adapting the JIT (Just-in-Time) model, which plays an essential role in supply chain management. The advantages of JIT purchase system are closed cooperation between buyers and sellers; long-term contracted with sellers to deliver small orders of high quality products frequently lead time reduction lower storage cost, carrying cost and order cost. The research is to develop supply chain integration with inventory model as well as to leverage fuzzy theory to deal with the uncertainties from demand and external supply. In addition, it is to establish the fuzzy multi-integration inventory model.

In the highly competitive supply chain environment, most companies cannot precisely obtain their performance status in real time such that they cannot make appropriate decisions to confront the market dynamics, demand variety and production exceptions…etc, and then they could be out of the advantage to compete. Therefore, the ability to measure the performance of operations can be taken as an important necessity for improvement, and companies have endeavored to increase their interests and capabilities of the performance measurement systems (PMSs). In fact, the lack of relevant performance measures has been recognized as one of the major problems in process and Supply Chain Management (SCM). Because of the very different views on what should constitute supply chain performance, many firms have found it difficult to practice SCM. As a prevalent industrial standard for SCM practices, Supply-Chain Operations Reference-model (SCOR-model) provides a systematic and comprehensive framework to measure a firm’s performance from different dimensions in the supply chain environment. In this thesis, we utilize Interaction Matrix to recognize the correlation between the performance metrics; construct a hierarchical structure based on standard formulas and definitions of SCOR-model and SAP R/3 ERP system and try to reflect the essence of the various supply chain performance dimensions. We further apply System Dynamics (SD) simulation to model the behaviors of the performance metrics based on several scenarios. Finally, Design of Experiments (DOE) is employed in analyzing the result of simulation through the what-if analysis and sensitivity analysis to provide the useful information for making decisions concerning SC performance.

In the case of scientific and technological progress and rapid economic development, the ecological environment bears many burdens. In particular, the manufacturing industry is burdening the entire environment. Nowadays, enterprises are also attracted by environmental awareness, so the concept of green supply chain is included. In the business operation objectives, to reduce resource waste. Therefore, based on this concept, this paper proposes a green closed supply chain integration operation model, and integrates the manufacturing supply chain and the reverse logistics chain to form a closed supply chain, that is, the reverse supply chain for recycling used products is the same path as the manufacturing supply chain; The reverse chain is mainly to recycle the second-hand products of customers and re-manufacture, and also consider the quality of second-hand products to explore its impact on the entire model. Due to the uneven quality of the recovered products, only some of the products can be selected for re-production and manufacturing, which reduces the manufacturer's output and causes a decline in the overall net income in the supply chain. The results show that when the second-hand raw material reproducibility rate (k) is 0.9, the net income is US$6,356,992; when the second-hand raw material reproducibility rate (k) is 0.8, the net income is US$6,352,867, which can verify the prediction of this study. . In addition, in the post-adjusted model of the second-hand raw material re-production rate (k), the sensitivity analysis of the impact of government subsidies and second-hand product recovery rate on net income is analyzed, and it is known that when government subsidies increase, the net income of the supply chain will It will increase accordingly, and when the recovery rate of second-hand products increases, its net income will also increase. However, the impact of government subsidies on the net income of the supply chain is obvious. Therefore, this study knows that “government subsidies” are the key factors in the model.

Abstract:

This thesis is intended to highlight the methodology of integrated planning for coordinating the supply chain in order to improve a system's overall performance. For that, a typical system is considered in which several products must be produced and distributed over several time periods. This work is done on a particular system that includes several suppliers, raw material processing plants, finishing plants and customers. Two main models have been developed based on different approaches, and they have been implemented in two different contexts. Various processes such as raw material procurement, capacity utilization, inventory, and distribution are integrated and optimized. More specifically, the following stages are considered: supply of raw material; production, at raw material processing plants, of product families; production, at finishing plants, of finished goods; and distribution of finished goods to customers. The finished goods are grouped into product families; setups are incurred at the raw material processing plants for product families, and at the finishing plants for individual products. Mixed Integer Program (MIP) formulations are utilized for optimizing the system. Test cases include both small sized and large sized problems. Analysis is done to gain insights into the workings of the models and systems like these in general. In the end, we have successfully demonstrated the utility of managing the supply chain effectively by integrating various processes along with the power and utility of MIP for representing such systems.

Abstract:

The South African sugar industry is a large industry which relies on expensive capital equipment to harvest, transport and process sugarcane. An average of 23 million tons of sugarcane are annually supplied to 14 mills from over 2 000 large-scale commercial growers and 48 000 small-scale growers. Supply chain stakeholders can benefit if operations are successfully streamlined. Computer-based mathematical models have been used in other industries to improve supply chains, especially in forestry, and are expected to play an increasingly important role in future planning and management. Management of sugar supply chains has historically focussed on generating competitive individual supply chain components. However, inter-component optimisation generally disregards many important intra-component interactions. Hence, efficiency improvements may be significantly limited. Integrated supply chain modelling provides a suitable approach for addressing this problem. The aim of this project was to develop and demonstrate, in concept, an integrated supply chain model for the sugar industry. Such a model could be used to address various integrated planning and management problems throughout the supply chain. A review of existing integrated agri-supply chain models was conducted followed by the development of CAPCONN, an integrated sugar supply chain model framework, that incorporate all steps from field to mill back end. CAPCONN estimates sugarcane quality, mill recovery, capacity utilisation and production costs. Bottlenecks are highlighted and the model could contribute towards capacity manipulation for efficiency improvements under different harvesting scenarios. CAPCONN was demonstrated by analysing a number of scenarios in a mechanisation case study at Komati Mill where sugarcane is currently burned and manually cut. A total of twelve scenarios were compared, including variations in cropping system and time of year. The model framework predicted that a decrease in sugarcane quality and sugar recovery would occur under mechanical harvesting scenarios. Estimated production costs were also higher, even though the transport fleet was significantly reduced. A manually cut green (unburned) harvesting scenario showed a further decrease in sugarcane quality and sugar recovery. Mechanical harvesting during wet weather caused a substantial reduction in supply chain capacity and an increase in production costs. CAPCONN output trends compared favourably with measured and observed data, though the magnitude of the trends should be viewed with caution, since the CAPCONN framework is only a prototype. This shows that it may be a suitable diagnostic framework for analysing and investigating the sugarcane supply chain as a single entity. With further development to a model, the CAPCONN model framework could be used as a strategic planning tool although, one drawback is that a relatively large number of technical inputs are required to run the model.

Due to the globalization of the economy in recent years, the supply chain management is a topic worthy of study. In this competitive environment, competition is not just between business and business, but it is the competition between the supply chains. Supply chain is the integration of the logistic and information from the suppliers to the consumers. All members of the supply chains must work together for the benefit of whole supply chain so as to optimize the whole system. In order to optimize the supply chain, cost consideration is vital. The research seeks to minimize the total cost of the whole supply chain. The key objective is to discuss the integration problem of a single distributor four-echelon integrated supply chain inventory model, and offer an integration mode of the upper-level and the lower-level of the enterprise, include the suppliers, manufacturers, distributors and retailers. This research aims at a single manufacturer and many manufacturers mode conditions respectively, and applies the dynamic programming method and mathematics software to derive simultaneously the best production strategy for the manufacturers, and the best transportation strategy for the distributor. Finally, sensitive analysis is carried out to study the influence of the stock strategy on the performance of the supply chain.

Supply chain management (SCM) becomes an important issue on manufacturing and service in today’s competitive business environment. On-time delivery is a primary determinant of customer satisfaction in a supply chain. Measuring and improving delivery can increase competitiveness advantage. In supply chain assess each stage delivery performance¸ we use process capability indices , , and Motorola six-sigma quality levels to propose a delivery performance analysis chart(DPAC). The DPAC proposed to provide several simultaneously visualized important features of delivery performance in a supply chain, like stage accuracy and stage precision. We also consider the uncertainty of estimated PCIs casued by sampling data and plot their lower confidence bounds(LCBs) in the DPAC to measure the minimum delivery capability of each stage in the supply chain. Finally, a case study related to a supply chain of notebook industry is presented to demonstrate how to use the DPAC incorporated with the lower confidence bound to evaluate delivery performance and decide make suggestion
