Abstract:

Logistics plays a crucial role in companies’ ability to sustain competitive on the market. Time is regarded as one of the important metric in terms of logistics, since time influences the lead time of the products, which results in the vital advantage of speed. The recent business environment forces Kinnarps Production AB, a manufacturer of furniture, to optimize their inventory material flow in a way of increasing their capability and capacity to load more distribution containers with goods daily. The present circumstances of the material flow are associated with number of negative factors. An automated guided vehicle (AGV) system is operating and handling the distribution of goods. Wrong sequence of activities, long transportations, high transportation delays, waiting time, varying numbers of AGVs, wastes, bottlenecks are among the important issues to be considered.

The purpose of this thesis is to analyze the material flow in Kinnarps Production AB’s inventory seven and to improve the AGV system activities within.

Concepts associated with identifying waste were used by separating value-adding activities from the non-value added ones. The usage of ideal reference systems techniques were the base for identifying problems. Concrete literature regarding AGV’s design system was applied in establishing different statements about the material flow and identification of problems. Different methods and techniques were used in approaching the research, but most above others is the case study approach. Numerous amounts of secondary data have been employed in verifying the collection of other data carried out by primary data collection as well as verifying the qualitative and quantitative analysis.

A mapping of the current system was established with respect to orders, times and distances. Numbers of congestion points were identified, non-value adding activities were eliminated or decreased, rearrangement of sequencing of different activities was considered and different pallets arrangement system was established. A stochastic model was used in identifying the AGV’s time variables in the system and estimating appropriate amount of AGVs within the inventory.

All the findings from different calculations and estimations were associated with Kinnarps Production’s future increased demand. Different issues and considerations were analyzed and appropriate suggestions were given for elimination of the negative factors in the inventory or their decrease. Among the most influencing results was the proper amount of AGVs in the inventory area, pallets rearrangement, different stocking policy, rearrangement in the sequence of activities, increase of the buffer for pallets used for loading containers, new conveyor system for the incoming goods in the inventory, transportation layout changes resulting in blocking free routines, separate control system, decrease of the effect of stoppages. All these findings are considered to optimize the material flow and increase the system capacity contributing to an increase of the daily containers outgoing from Kinnarps Production AB.

A high-mix, make-to-order production system can become inefficient when non-value added operations consume too much time, space or labour. To address these issues, cell re-layout is conducted and a CONWIP system is proposed. The cell re-layout started with data collection on current layout, product mix and routings, then the current layout was modified to develop several alternatives, and finally the best alternative was selected based on a set of criteria. The Pull system design began with comparison between Kanban and CONWIP with respect to an actual production system, and then the CONWIP system was selected and a sample case study based on ARENA 12.0 was included to study the characteristics of CONWIP. Finally, transformation of the actual production system to CONWIP was studied in ARENA simulation to determine its optimal CONWIP setting. It can be concluded that the cell layout resulted in improved operator efficiency and savings in area occupied, while the CONWIP system leads to reduction in amount of work-in-process, and stabilization of manufacturing lead time.

Abstract:
Workload control (WLC) systems constitute a framework mainly for the inputoutput control systems which regulate both jobs&rsquo
queues into the workshop and the flow of finished goods out of the workshop. This study is concerned with the job entry and release level of WLC which maintains a pool of unreleased jobs for the controlled release of jobs. While most of the studies in WLC concepts deal with the centralized workload control, our study decentralizes the job entry and release control and makes workstations more powerful in schedule decision making. Job&rsquo
s information is sent to the workstations by mediator which is the supervisor of the workstation. Both mediator and work stations are represented by agents in a distributed system. Jobs&rsquo
routing information is assumed to be known in advance. The developed system is verified and validated by means of test runs. Results are analyzed as well.

Abstract:
A high level of competition in the food industry, specifically in the Middle East and the UK has forced companies to improve their processes by reducing lead time, waste, and costs and increasing production efficiency. The main challenge to the achievement of the process improvement objectives is the high level of process variability. Therefore, this research investigates the different types of variability in food production system and proposes a methodology to reduce the effect variability in food production system. The variability can be caused by several factors, for instance, in biscuit production lines variability can be induced due to short breakdown and long breakdown, variable processing times, variable temperature, etc. The proposed approach addresses process time variability issues associated with both make-to-stock (MTS) and make-to-order (MTO) manufacturing environments using an iterated approach. The proposed methodology integrates process mapping, (which is a lean tool for identifying value added and non-value added activities), discrete event simulation (to mirror the real production line), Taguchi orthogonal arrays (to generate different scenarios in order to investigate the effect of variability on the simulation model), correlation analysis (to identify the highest variability factors), and the rule based system (to improve food production system performance based on identified key performance indicators (KPIs)). The research uses a biscuit production line as a case study to validate the proposed methodology. The application of the proposed approach determines that the highest effected KPI is %working. The results showed that after implementation of the rule-based system, key performance improved in high variable areas. Results analysis based on before scenario shows that %working performance indicator is highly effected by variable temperature, speed, and breakdown factors for high variable areas such as baking, cooling, aligning, and packing. Based on identified factors and high variable areas, rules are developed by applying standardisation setting (SOP, WI, PP) in high variable areas and the results shows %working improved in baking by 4.78%, in cooling by 16.06%, in aligning by 0.35%, in packing machine1 by 2.5%, in packing machine2 by 2.37%, in packaging1 by 3.35%, and in packaging2 by 3.16%. The integrated method allow quick response , control the environment without production interruption, reduce number of experiments , and reducing variability in high variable areas, which narrowed the improvement in the required areas and increased its effectiveness.

Abstract:
A industrialização da construção civil é uma das possíveis estratégias adotadas para melhorar a qualidade e produtividade da produção neste ambiente altamente competitivo. Entretanto para uma melhoria na eficiência da produção, a simples implantação de uma tecnologia industrializada não é o suficiente. Existe a necessidade de melhorar os sistemas de gestão como um todo. O sucesso da implementação de sistemas de planejamento como o Last Planner, desenvolvidos especialmente para a construção civil, instiga o desenvolvimento de estudos em diferentes processos produtivos. Em relação à implementação de princípios da produção enxuta, o sistema é apontado como um ponto de partida para uma empresa atingir uma estabilidade básica. Este estudo foca-se em um tipo específico de sistema de produção industrializadas chamado engineer-to-order (ETO), quando a requisição de produto pelo cliente é realizada na fase de projeto. Neste tipo de sistema construtivo há uma necessidade de integrar a fabricação das peças conforme as necessidades do canteiro de obras. Esta pesquisa visa a desenvolver um modelo integrado de planejamento e controle da produção de sistemas ETO pré-fabricados para construção civil, integrando o projeto, manufatura e montagem em obra. A pesquisa faz parte de uma parceria da Universidade Federal do Rio Grande do Sul com uma empresa de fabricação e montagem de estrutura (Empresa A) metálica interessada em melhorar seus processos de planejamento e controle da produção. O método de pesquisa é baseado na pesquisa construtiva, ou design science, em que há um esforço do pesquisador em produzir um artefato como resultado da pesquisa, que neste caso, é um modelo de planejamento e controle da produção. O processo de implementação de mudanças da empresa adotou a estratégia da pesquisa-ação, de forma que as soluções eram coletivamente acordadas com as pessoas responsáveis pela sua utilização, para garantir que a mesma se efetivasse nos procedimentos da empresa. Neste tipo de estratégia procura-se estabelecer ciclos de aprendizagem ao longo da pesquisa, em que as soluções são continuamente avaliadas e adaptadas para melhoria dos processos em análise. Os resultados da empresa A foram divididos em quatro fases de implementação. Na primeira fase houve um esforço em consolidar uma integração nos planos de curto prazo. Na segunda fase o foco foi no sistema como um todo, promovendo mecanismos para coletar informações sobre o andamento das obras para retroalimentar a fábrica. As barreiras enfrentadas para garantir esta retroalimentação demonstraram a necessidade da utilização de outros métodos. Por isso, a terceira fase se concentrou no desenvolvimento de ferramentas de gestão visual para melhorar os processos analisados nas fases anteriores. A quarta fase do estudo foi baseada no estudo dos processos logísticos da empresa, visto que representam a interface entre fábrica e obra. Terminado o estudo na empresa A dois estudos foram conduzidos no exterior para compreender contextos distintos de sistemas de produção ETO. O primeiro (empresa B) responsável pelo sistema de climatização da edificação. A empresa realiza o projeto, fabricação e instalação dos sistemas de dutos em metal laminado, assim como o maquinário necessário para as trocas de ar. O estudo foi baseado no fornecimento do sistema para uma obra específica. Neste estudo foram desenvolvidas ferramentas de planejamento para facilitar a sincronização entre fabricação e instalação do material em obra. O segundo estudo (empresa C) foi realizado em uma empresa de estrutura metálica que desenvolveu uma conexão inovadora, facilitando seus processos produtivos. Este estudo teve caráter descritivo, analisando como a sua tecnologia facilitou o sistema de planejamento e controle da produção. A partir dos resultados obtidos nos estudos foi possível desenvolver o modelo final de planejamento e controle da produção para sistemas ETO de pré-fabricados. A maioria dos processos propostos neste modelo foi testada na empresa A. Embora a empresa estudada ainda necessite implantar algumas melhorias no seu sistema de planejamento e controle para se adequar ao modelo proposto, as mudanças realizadas trouxeram benefícios na comunicação e sistematização das informações entre os diferentes níveis de planejamento e controle. As contribuições teóricas do trabalho foram um modelo conceitual para compreender a complexidade neste tipo de sistema de produção; a identificação dos principais requisitos para desenvolver sistemas de planejamento e controle da produção para este ambiente; e a adaptação do conceito de WIP utilizando o status dos produtos.
The industrialization of construction work is one of the ways it is possible to achieve better quality and productivity in this competitive environment. However, in order to improve efficiency using industrialized technologies is not enough. There is a need to improve planning and control systems. Although the Last Planner System has been developed for the construction environment, since it was devised the successful results promoted its implementation in different production environments. Regarding lean production implementations, the system has been pointed out as a starting point for a company to achieve the basic stability. This study is focused in one type of industrialized production system: the engineer-to-order. By industrialized, it is the prefabrication that has been addressed. In these kinds of production systems, there is a need to integrate the prefabrication plant with the construction site needs. This research project aims to develop an integrated planning and control production planning and control model for ETO prefabricated systems, integrating design, manufacturing and site assembly. The research is part of a partnership with a steel fabricator company (Company A) that was interested in improving its production planning system. The research method is grounded in the design science research, in which there is an effort from the researcher to develop an artefact as an output of the research process, in this case, a planning and control model. The implementation adopted some strategies from the action-research, so some solutions needed to be collectively constructed between the researcher and the practitioners, in order to have an effective use in the organization. Following this strategy, it is possible to have same learning cycles during the implementation of the solutions, which are continually assessed and adapted in order to improve the processes analysed. The results are divided into four phases of implementation. In the first step the main effort was in consolidating an integrated planning and control process for the short-term in the production units. In the second step the focus was the overall system, mainly providing mechanisms to collect the status of all construction sites for the plant. The barriers to improve this feedback process brought to light the need for using visual management tools. This development concerned the third step of implementation, further improving the changes made in the previous phases. The fourth step was based on the analysis of the logistics processes, as the interface between the plant and site assembly. After the main empirical study on Company A, two studies were carried out abroad in order to understand a different context of ETO production systems. The first concerns a mechanical contractor situated in a high complex project. In this study, it was possible to develop some planning tools to facilitate the analysis between the fabrication and site installation of the products. The second concerns a steel fabricator focused on the structural system. This was a descriptive study that analysed the differentiation of the products provided by this company and the impact of it in the planning and control system. Based on the results obtained in the implementation process, the integrated planning and control model for ETO building systems was devised. Most of the processes proposed in the model were assessed in Company A. Although there is still a need to improve the production planning and control system of that company, the implementation enhanced the communication between the operational and tactics level and also promoted a systematic way to collect information for each level of the production planning and control system. The theoretical contributions of the research were the development of a framework to understand the complexity of this kind of production system; the identification of the main requirements for developing a planning and control system for this environment; and the adaptation of the concept of WIP using the status of the product.

Abstract:
Augmenter la part de marché du bois dans la construction non résidentielle est un objectif important dans les pays où les produits forestiers et de bois d'ingénierie jouent un rôle fondamental. Afin de faciliter la production de structures en bois innovantes, il est nécessaire de mettre sur pied des procédures de réingénierie en termes d’analyse de marché et d’amélioration de la productivité. L'objectif principal de cette thèse est de faciliter la production de bois d'ingénierie (produits en lamellé-collé) destiné à être utilisé dans des structures en bois innovantes telles que les résilles en bois. Pour atteindre ce but, trois objectifs spécifiques sont définis. Le premier objectif est de déterminer les phases de production et les opportunités de marché pour la production de résilles en bois. À cet égard, une revue de la littérature académique et de la littérature grise a été réalisée, et vingt échantillons ont été identifiés et analysés à l'aide de diagrammes de processus et de catégorisations. Les résultats ont montré qu’une structure en résille de bois est utilisée dans l'industrie de la construction en Europe et qu'elle est moins connue en Amérique du Nord, ce qui offre une opportunité de marché pour sa production et sa construction. La catégorisation des échantillons étudiés dans les petites, moyennes et grandes structures et l'identification des acteurs pour chaque catégorie fournissent une vue d'ensemble pour les entreprises qui envisagent la production de cette structure. Le deuxième objectif de cette thèse est de fournir un modèle de simulation pour la production de bois lamellé-collé dans de petites usines et le processus d'application de techniques Lean pour apporter des améliorations. À cet égard, le système de production d’une entreprise québécoise a été analysé et un modèle de simulation créé. Afin d'éliminer chaque source de gaspillage, un outil Lean a été suggéré en fonction de la réalité du système à l’étude. Les résultats ont montré une amélioration notable du temps d’attente et de cycle suite à l’utilisation de techniques issues du Lean. Ils ont également contribué à souligner qu’une élimination du gaspillage limitée à 50% pouvait améliorer la considérablement la productivité pour les petites entreprises et s’avérer un premier pas important dans l’implantation du Lean. Le troisième objectif est de fournir un outil de planification et d'ordonnancement de la production dans un contexte de production multi-projets d’ingénierie sur commande (Engineer-to-Order) de bois lamellé-collé. À cet égard, des modèles d'optimisation ont été créés. Le premier modèle (modèle 1) concerne la minimisation du coût de production total, tandis que le modèle 2 vise la minimisation de la durée totale des projets. Le modèle 3 cherche plutôt à réduire le temps de mise en route sur la presse, le poste goulot du système de production considéré. Le modèle 4 intègre les trois objectifs de réduction des coûts, de durée et de temps de mise en route. Deux scénarios d’ajout de projets de grande et de moyenne envergure ont été conçus et testés. Le test des scénarios démontre qu'il y a une capacité suffisante pour l’ajout d’un projet de grande envergure ou de neuf projets de taille moyenne sans recourir à la sous-traitance. L'ajout d'un projet de grande envergure est plus sensible à la période d'insertion, pouvant exiger du temps supplémentaire selon la date de début du projet. Les travaux de cette thèse permettent donc de fournir des outils d'aide à la décision pour les entreprises œuvrant dans un milieu d'ingénierie sur commande afin d'améliorer leur productivité et la standardisation de leurs processus.
Increasing the share of wood in non-residential construction is an important goal in countries with major forest and engineered wood products. In order to facilitate the production of innovative timber structures, procedures should be re-engineered in terms of market analysis and productivity improvement. The main objective of this thesis is to facilitate the production of engineered wood to be used in innovative wood structures such as timber gridshell. To achieve this goal, three specific objectives are defined. The first objective is to determine production phases and market opportunities for the production of timber gridshell. In this regard, a review of the academic and grey literature was conducted, and twenty samples were identified and analysed by making process charts and categorisations. The results showed that gridshell is used in the construction industry in Europe and is less recognised in North America, which provides a market opportunity for its production and construction. The categorisation of studied samples in small, medium and large structures provides an overview for the companies who consider the production of this structure. The second objective of this thesis is to provide a simulation model for the production of glued laminated timber in small factories and the process of applying lean techniques to make improvements. In this regard, the production system of a Small and medium-sized enterprise (SME) was analysed, and a simulation model was created. In order to eliminate each source of waste, a lean tool was suggested according to the reality of the system under investigation. The lean methods were applied in the simulation model to analyse the potential improvements. Results showed a noticeable improvement in waiting and cycle time. It also showed that applying even 50% elimination of the wastes is also a considerable solution to improve productivity as a beginning step for SMEs. The third objective is to provide a production planning and scheduling tool in the context of multi-project engineer-to-order production of glued laminated timber. In this regard, optimisation models were created. The first model (model 1) concerns the minimisation of total production cost while model 2 aims to minimise projects’ makespan. Model 3 introduces the set-up time reduction and model 4 integrates the three objectives of minimising cost, makespan and set-up time. Two scenarios of adding complex and medium projects were designed and tested. Testing the scenarios showed that there is enough capacity for adding one complex project or nine medium projects without the need to outsource. Adding a complex project is more sensitive to the insertion period and beginning the project in different weeks leads to different results in terms of the overtime requirement. As a result, the work of this thesis provides decision support tools for engineer-to-order environments which could help SMEs to improve their productivity and standardisation.

This work departed from the finding that the changes occurred in the industrial competitive scenario are in conformity with the unfavorable conditions recognized for the use of the kanban system and that, due to this, the use of this well-known Systems for Coordination of Purchase and Production Orders (SCO) needs to be reviewed. Following, this research aims to evaluate the evolution of the utilization of the kanban system and study the adaptations made in its logic work to adjust it in face to the new conditions, and to evaluate the advantages and disadvantages of these adaptations. First of all, literature reviews regarding kanban system were made, and thirty three different adaptations were studied, classified and analyzed. It was found that, among other topics, the development of the adapted systems, in general, is in an initial stage, once the majority of the proposals are theoretical and might be considered to generate more appropriated practical forms. Afterwards, field research was realized, by means of a survey and case researches. In the survey, it was selected a non-probabilistic sample of thirty companies from São Paulo State that were implementing the kanban system in the beginning of the 90 s. It were identified 18 adaptations in practice in São Paulo State, however only 5 were analysed in the case studies. Among the 18 adaptations, 7 follow the logic of the original system and 11 do not. Thereby, it was proposed a procedure to evaluate the use of the kanban system in that industrial companies by means of the original work characteristics, production environment conditions and advantages of the system. The five adaptations analysed in the case studies have, as the main change, the utilization of only one type of signal or card. It was also concluded, by the use of the procedure, that the companies that use adaptations of the kanban system miss (in larger or smaller degree, depending on the adaptation) the following advantages: efficient production control; facility of problem causes identification; decrease of work in process; decrease of the lead-times; decrease of the waste; empowerment; simplicity of the administration mechanisms and efficient information control.
Este trabalho partiu da averiguação de que as mudanças recentes ocorridas no cenário competitivo industrial correspondem às condições reconhecidamente desfavoráveis ao uso do sistema kanban e que, devido a isso, o uso deste conhecido Sistema de Coordenação de Ordens de Produção e Compra (SCO) precisa ser revisto. Com isso, este trabalho tem como principais objetivos avaliar a evolução da utilização do sistema kanban e estudar as adaptações efetuadas em sua lógica de funcionamento para a adequação deste sistema frente às novas condições competitivas, bem como avaliar as vantagens e as desvantagens dessas adaptações. Inicialmente foram realizadas revisões bibliográficas sobre o sistema kanban, onde trinta e três adaptações diferentes foram identificadas, classificadas e analisadas. Constatou-se, dentre outros pontos, que o desenvolvimento dos sistemas adaptados no geral encontra-se numa fase inicial, uma vez que a maioria das propostas são apenas proposições teóricas que devem ser levadas em consideração para a geração de formas mais apropriadas à prática. Após isso, foram realizadas as pesquisas de campo, por meio de um survey e de estudos de caso. No survey utilizou-se uma amostra não-probabilística de trinta empresas do estado de São Paulo que estavam implantando o sistema kanban no início da década de noventa. Foram identificadas 18 adaptações na prática sendo utilizadas por empresas industriais no Estado de São Paulo, porém somente 5 foram analisadas à fundo nos estudos de caso. Das 18 adaptações 7 seguem a lógica de funcionamento do sistema kanban original e 11 não seguem. Em função dos resultados encontrados no survey que demonstraram a existência dessas adaptações, foi proposto um procedimento para avaliação da utilização do sistema kanban em empresas industriais por meio do relacionamento entre características de funcionamento original, condições do ambiente produtivo e vantagens do sistema. As cinco adaptações estudadas nos estudos de caso possuem como principal alteração a utilização de apenas um sinalizador. Foi concluído também, por meio da aplicação do procedimento, que as empresas que utilizam adaptações do sistema kanban deixam de usufruir (em maior ou menor grau, dependendo da adaptação) das seguintes vantagens: controle eficiente dos estágios produtivos; facilita a identificação da raiz de problemas produtivos; redução dos níveis de estoque; redução dos lead-times; redução de refugos e retrabalhos; atribuição de empowerment aos operadores; simplificação dos mecanismos de administração; e controle eficiente de informações.

Abstract:
This report is presenting a master thesis work in Industrial Design Engineering with a focus on production development at Luleå University of Technology. The thesis work was conducted in the spring term of 2021 at the engine assembly plant of Scania in Södertälje. The project aimed to map the special-order process to create an overview of the process and present improved work patterns. The project also aimed to map the impact of working from home. A special order is an order that is tailored for the customer in a way that is not supported by the standard order system but produced in ordinary production, this is made possible using the S-order process. The background of the project was that the process is among other things, unclear and person dependent and has resulted in stops and unnecessary and costly maneuverers in the production. The project was a pilot study with a focus on the mapping and analysis of the current and future state of the process, limited to the engine assembly, marine and industry engines and with a focus on the local product preparators. Interviews, observations and document studies were the main methods used to map the process. These data collecting methods complemented each other to create an understanding of the situation using a broad range of perspectives. The result of the data collection was then analysed to present the process and the perceptions of the process to find problems and needs. A specification of requirements was used to summarise the results and to be used during concept development. Concepts were developed through a workshop where the participants brainstormed solutions on the found problems and needs. Literature research was conducted about customisation, digital work environment and learning organisation. Research on customisation was used to understand the background and the challenges with it. The digital work environment consisted of the effects of digital work as well as research on how to design and implement a digital work environment. Research on learning organisation was used to support the presented needs and proposed improved work patterns. The mapping of the current state showed that it is a quick process that affects a lot of people who together quickly must assess if and how the orders are and will be possible to deliver. A coordinator at the engine assembly must make sure that the right people are informed and involved meanwhile these people have been shown to lack understanding of the process its responsibilities and activities, resulting in e.g., worry and stress. To improve the process, a proposition was made on focusing on improving the transfer of knowledge and experience, create a common understanding and approach and improve communication and collaboration. Four concepts were presented where the focus was on learning organisation, continuous improvements and based established methods used at the engine assembly.

Syftet med arbetet var att kartlägga S-orderprocessen för att skapa en översikt över denna och presentera förbättrade arbetsmönster. Projektet syftade också till att kartlägga effekterna av att arbeta hemifrån. En specialorder är en order som skräddarsys för kunden på ett sätt som inte stöds av det vanliga ordersystemet men som produceras i den vanliga produktionen, detta möjliggörs genom S-orderprocessen. Bakgrunden till projektet var att processen bland annat är oklar och personberoende och har resulterat i stopp och onödiga och kostsamma manövrer i produktionen. Projektet var en förstudie med fokus på kartläggning och analys av processens nuvarande och framtida tillstånd, begränsat till motormonteringen, industri- och marina motorer och med fokus på de lokala produktberedarna.Intervjuer, observationer och dokumentstudier var de centrala metoderna för att kartlägga processen. Dessa datainsamlingsmetoder kompletterade varandra och skapade en förståelse för situationen utifrån ett brett spektrum av perspektiv. Resultatet av datainsamlingen analyserades för att presentera processen och uppfattningarna av denna för att hitta problem och behov. En kravspecifikation användes för att sammanfatta resultaten och för att användas under konceptutveckling. Koncept utvecklades genom en workshop där deltagarna brainstormade lösningar på funna problem och behov.Litteraturforskning genomfördes om kundanpassning, digital arbetsmiljö och lärandeorganisation. Forskning om kundanpassning användes för att förstå bakgrunden och utmaningarna med det. Digital arbetsmiljö bestod av att förstå effekterna av det samt forskning om hur man utformar och implementerar en digital arbetsmiljö. Forskning om lärandeorganisation användes för att stödja de presenterade behoven och föreslagna förbättrade arbetsmönster.Kartläggningen av nuläget visade att det är en snabb process som påverkar många människor som tillsammans snabbt måste bedöma om och hur ordern är och kommer att vara möjliga att leverera. En koordinator vid motormonteringen måste se till att rätt personer är informerade och involverade samtidigt som dessa personer har visat sig sakna förståelse för processen, dess ansvar och aktiviteter, vilket resulterar i bl.a. oro och stress. För att förbättra processen föreslogs att fokusera på att förbättra kunskaps- och erfarenhetsöverföringen, skapa en gemensam förståelse och tillvägagångssätt och förbättra kommunikation och samarbete. Fyra koncept presenterades där fokus var på lärande organisation, kontinuerliga förbättringar och baserade på etablerade metoder som användes vid motormonteringen.

Abstract:
Lean Manufacturing (LM) is widely accepted as a world-class manufacturing paradigm, its currency and superiority are manifested in numerous recent success stories. Most lean tools including Just-in-Time (JIT) were designed for repetitive serial production systems. This resulted in a substantial stream of research which dismissed a priori the suitability of LM for non-repetitive non-serial job-shops. The extension of LM into non-repetitive production systems is opposed on the basis of the sheer complexity of applying JIT pull production control in non-repetitive systems fabricating a high variety of products. However, the application of LM in job-shops is not unexplored. Studies proposing the extension of leanness into non-repetitive production systems have promoted the modification of pull control mechanisms or reconfiguration of job-shops into cellular manufacturing systems. This thesis sought to address the shortcomings of the aforementioned approaches. The contribution of this thesis to knowledge in the field of production and operations management is threefold: Firstly, a Multi-Agent System (MAS) is designed to directly apply pull production control to a good approximation of a real-life job-shop. The scale and complexity of the developed MAS prove that the application of pull production control in non-repetitive manufacturing systems is challenging, perplex and laborious. Secondly, the thesis examines three pull production control mechanisms namely, Kanban, Base Stock and Constant Work-in-Process (CONWIP) which it enhances so as to prevent system deadlocks, an issue largely unaddressed in the relevant literature. Having successfully tested the transferability of pull production control to non-repetitive manufacturing, the third contribution of this thesis is that it uses experimental and empirical data to examine the impact of pull production control on job-shop performance. The thesis identifies issues resulting from the application of pull control in job-shops which have implications for industry practice and concludes by outlining further research that can be undertaken in this direction.

Abstract:
Industrialization of construction is a business strategy to significantly improve competitiveness. However, the organization structure of the construction firms needs to support the new production system. The knowledge on why and how this business development can be accomplished is scarce, both within academia and in business practice. This research seeks to fill this knowledge gap. The purpose of organization structure and the production system have is to coordinate the firm’s processes and control the work performing resources. Information is one of the most fundamental dimensions for steering and controlling the work. The different information types are determined by the firm’s product customization strategy and the production system flexibility. Further, diverse information types are managed in different extent by the organizational steering mechanisms. Consequently, firms with dissimilar customization strategy or production flexibility should organizationally be designed differently in order to be efficient. The developed model identifies four generic production topologies: “engineer-to-order” (ETO), “manufacture-to-order” (MTO), “assembly-to-order” (ATO), and “make-standard-products” (MSP). The differences between the topologies can be related to the location of the “customer-order-decoupling-point” (CODP) in the product realization process; and to what extent the upstream and downstream processes continuously use stored information or process information to accomplish the work of each product order. The model predicts which organization structure mechanisms that should be used for which processes for each production topology. It is the specific configuration of the mechanisms that gives each production topology their organizational capability. The model has been validated by case studies in four organizations, each representing one of the four generic production topologies. Three cases considered housing and one studied truck manufacturing. It has been shown that the conventional housing firms have an ETO-production topology, while industrialized housing firms belonging to one of the others, i.e. MTO, ATO or MSP. The reason is that ETO-firms rely on crafts-based production to manage the work, while the other topologies base their steering mechanisms on industrial principles. These two types of production are fundamentally different, which also explain the need for different organization structures. The research complements previous knowledge and significantly increases the ability to predict, analyze and explain an organization’s design and behavior. The model can be used in practice to guide business development work and performance improvement programs.

Full text
Abstract:
The token economy is a widely used and versatile motivational system within applied behavior analysis. Moreover, token reinforcement procedures have been shown to be highly effective in the treatment of children with autism spectrum disorder (ASD). In the experimental analysis of behavior, token reinforcement contingencies are conceptualized as three interconnected schedule components: (1) the token-production schedule, (2) the exchange-production schedule, and (3) the token-exchange schedule. Basic work with nonhuman subjects has demonstrated that the exchange-production schedule is the primary driver of performance in these arrangements, and that variable-ratio exchange-production results in reduced pre-ratio pausing and greater overall rates of responding relative to fixed-ratio exchange-production schedules. However, little applied research has been conducted to assess the generality of these findings within applied settings. The purpose of this study was to determine if fixed- and variable-ratio token exchange-production schedules would exert differential effects on pre-ratio pausing and overall rates of responding for three children with ASD during a free-operant sorting task. The results showed that pre-ratio pausing and overall rates of responding were not differentially effected by the fixed- and variable-ratio exchange-production schedules. Discrepancies between the experimental work and the current study are discussed along with additional limitations.

Abstract:
This thesis is primarily concerned with language production. In particular it investigates two issues: First, it explores some of the processing mechanisms underlying the production of different syntactic structures and word orders. Second, it explores the production of different syntactic structures and word order from a developmental perspective. These two issues are investigated experimentally and from a cross-linguistic point of view. First, a description is given of the possible word order permutations that Catalan allows and under which circumstances these word orders are produced. This is extended with a corpus analysis of spoken Catalan. The aim of this study is twofold: on the one hand, it aims to present the different positions where subjects and complements of the verb can appear in a sentence. On the other, it aims to compare the use of passivization between spoken and newspaper text in Catalan. Second, my experimental work in language production in four languages is presented. These languages include English, Brazilian Portuguese, Catalan and Spanish. The main aim of this study is to explore the effects of the non-linguistic factors of animacy and frequency upon the production of different word orders. The results of four experiments in the four languages mentioned yield evidence that these non-linguistic factors affect the on-line processing of language production. In the four languages, participants tend to prefer to produce syntactic structures which allow animate entities to be realised as the sentential subject, even if this means producing a passive structure rather than a (usually preferred) active structure. I have also found evidence that in some languages (e.g. Catalan and Spanish) animate/frequent entities appear at initial sentence position in the grammatical category of object (in dislocated active constructions). These results are explained on the light of some of the models of language production (e.g. Bock 1987a; Bock and Levelt 1994). Third, further cross-linguistic experiments in three languages (English, Catalan and Spanish) are presented. There I show that one particular contextual factor, discourse salience, can also affect the realisation of different syntactic structures during production. Entities which have been made more salient by the preceding context are more likely to appear as sentential subjects or in early sentential positions than entities which have also been introduced in previous discourse but are less salient. I suggest that these effects can be explained using the same mechanisms that explain other non-linguistic factors (e.g. animacy). The results also suggest that in the absence of context, animacy is a strong determinant of syntactic structure and word order, whereas in context, discourse salience may largely override animacy effects. Finally, these results suggest that from a processing point of view, the Given/New partition is not enough to account for the information structure of a sentence, but a more fine-grained distinction is need, in keeping with some recent pragmatic theories (e.g. Prince 1981, 1992; Sgall et al. 1986). Finally, I investigate the production of different word orders from a developmental point of view. In particular I examine the relationship between age and the production of different word orders by Catalan children, ranging from 4;11 to 11;11 years. The results of an experiment run with these children show that a dislocated active is a construction already consolidated at age 5. In contrast, the passive clause is a construction still not fully acquired at age 11. These results seem to suggest that for Catalan children, a dislocated active is a syntactic structure that is available earlier than the passive structure. Conversely, the placement of a patient in subject position and the creation of a verbal passive voice occurs later than simple word order permutation. Finally, a comparison between these results and existing results from English children shows that there are cross-linguistic differences on the age of production of passive clauses: while English children already produce passives at age 5, Catalan children start producing passives at age 11. I suggest some possible explanations for the cross-linguistic differences in the production of different syntactic structures. Overall, the main aim for this study is to gain insight into the production of different syntactic structures and word orders from a psycholinguistic and developmental point of view.

Full text
Abstract:
Rethinking Indigenous legal traditions is fundamentally about rebuilding citizenship. The theory underlying this paper is that it is possible to develop a flexible, overall legal framework that Indigenous peoples might use to express and describe their legal orders and laws, so that they can be applied to present-day problems. This framework must be able to, first, reflect the legal orders and laws of decentralized (i.e., non-state) Indigenous peoples, and second, allow for the diverse way that each society’s culture is reflected in their legal orders and laws. In turn, this framework will allow each society to draw on a deeper understanding of how their own legal traditions might be used to resolve contemporary conflicts, complex social injustices, and human rights violations.The Canadian state is not going away and the past cannot be undone. This means that Indigenous peoples must figure out how to reconcile former decentralized legal orders and law with a centralized state and legal system. Any process of reconciliation must include political deliberation on the part of an informed and involved Indigenous citizenry. We have to answer the question, «Who are we beyond colonialism?»
Repensar las tradiciones legales indígenas es fundamental para la reconstrucción del concepto de ciudadanía. La teoría subrayada en este ensayo es que sí es posible desarrollar un flexible marco legal general que los pueblos indígenas deberían usar para expresar y describir sus órdenes legales y derechos, tal es así que pueden ser aplicados a los problemas actuales. Este marco debe ser capaz, primero, de plasmar los ordenamientos legales y los derechos siguiendo la forma descentralizada (esto es, no-estatal) de los pueblos indígenas; y segundo, permitir que las diversas formas de la cultura de cada sociedad sean reflejadas en sus ordenamientos jurídicos y derechos. Este marco permitirá, a su vez, que cada sociedad haga uso de un entendimiento profundo sobre cómo sus tradiciones legales deberían ser usadas para resolver conflictos contemporáneos, injusticias sociales complejas y la violación de derechos humanos.El Estado canadiense no se está debilitando y el pasado tampoco está descartado. Esto significa que los pueblos indígenas deben analizar cómo reconciliar sus antiguos ordenamientos legales y derechos descentralizados con el Estado y el sistema legal centralizados. Cualquiera fuera el proceso de reconciliación debe incluir una deliberación política sobre la ciudadanía indígena informada y comprometida. Tenemos que responder ala pregunta: «¿Quiénes somos nosotros más allá del colonialismo?».

The rapid growth of the Print on Demand (POD) business has necessitated a capacity expansion plan that spans the next five years. After analyzing sales data it was determined that more titles are selling in larger quantities. For these titles, the current make-to-order model does not represent the optimal manufacturing and fulfillment strategy. This preliminary insight led to the realization that an inventory model that uses demand forecasts and a cost analysis for each title should be used to determine the optimal ordering quantity for qualifying titles, in an initiative called high volume pre-builds. Additionally, an initiative called predictive manufacturing should be used concurrently to provide customer experience improvements to titles that sell in large quantities but do not qualify for high volume pre-builds. The development of a hybrid make-to-stock, make-to-order (MTS-MTO) production optimization model will lead to pre-building between 1.1M and 2.1M retail units per year, but could be scaled upward. Pre-building allows for cost savings through economies of scale in manufacturing and through transportation savings based on inventory placement and network topology. An additional 300K+ annual retail titles will be eligible for predictive manufacturing, which will also benefit from transportation savings. The customer experience improvements alone would make these initiatives worth pursuing even if they were NPV neutral or slightly negative. However, they are a clear win when also considering overall integration and cost savings. These initiatives will drive a lower cost structure for book manufacturing that benefits all stakeholders (Amazon, authors, and customers), which will lead to the continued, rapid growth of POD.

Abstract:
As the effort of today’s industries to continuously move towards lean production, pull production system has been developed as one possible solution of lean. It is popularly known in the industry world, and is indeed a proven technique to achieve substantial savings on inventory, production cost incurred by manufactures all over the world. However, a careful understanding of pull production systems is required to access its suitability to a particular production setup. It is necessary to develop a proper way to implement pull production systems.             This study is based on a real life scenario in a leading driveline manufacturing company. The production system is studied in detail as regard to its production characteristic. A theoretical review is first made as research foundation. A careful analysis study within the company is conducted with all the existing constrains to figure out improvement opportunities. Eventually, from the applicability point of view, proposals of future pull production system implementation have been developed. The objective of the proposals is to minimize the identified weaknesses of the current system, including long lead time, low flexibility and unconnected flow.

Abstract:
Syftet med denna rapport är att kartlägga Scania Production System (SPS), hur det motiverades och implementerades inom Scanias organisation samt dra kopplingar mellan tidigare reformer och SPS. Vi vill ta reda på hur Scania lyckats skapa ett eget skräddarsytt produktionssystem som visat sig vara så framgångsrikt och hur detta infördes inom hela organisationen. SPS är ett resultat av Toyota och deras Toyota Production System (TPS) efter ett nära samarbete mellan Scania och Toyota sedan början av nittiotalet. Scanias värderingar, principer och prioriteringar beskrivs av SPS och har visat sig vara en av företagets konkurrensfördelar genom ökad effektivitet samt produktivitet inom produktionen. TPS fick mycket av sin inspiration av de tidigare reformerna Taylorismen och Fordismen ur rationaliseringsrörelsen. Detta genom Taylors idéer om standardisering och Fords löpandebands-princip. Toyota var även bland dem första att utforma och tillämpa de logistiska reformerna Total Quality Management, Lean Production och Just-In-Time i sitt produktionssystem. Reformer som används och är välkända inom många företag inte minst Scania och SPS. Rapporten uppfyllde sitt syfte genom intervjuer och analys av konceptlitteratur för att kunna konstatera att det finns en röd tråd inom företaget och att det finns en tydlig koppling mellan SPS och tidigare reformer. Avslutningsvis lyckades vi även analysera och dra slutsatser om hur SPS utformades, motiverades och implementerades. Utformningen av SPS gick till genom ett nära samarbete mellan ledningar på Scania och Toyota vilken Scania på så sätt kunnat ta inspiration ifrån och kunnat anpassa systemet efter Scanias kultur. Hur sedan SPS motiverades och implanterades föregick i en ledningsprocess som Scania tillämpade inom organisationen. Lösningen kom att bli avgörande för framtiden, ledarskapet. Man tillämpade ett nytt tankesätt genom hela verksamheten vilket har visat sig vara framgångsrikt.
The purpose of this report is to map the Scania Production System (SPS), how it was motivated and implemented within Scania's organization, as well as linking previous reforms with SPS. We want to find out how Scania managed to create its own customized production system that proved being successful and how it was introduced throughout the organization. SPS is a result of Toyota and their Toyota Production System (TPS) following a close collaboration between Scania and Toyota since the early 1990s. Scania's values, principles and priorities are described by SPS and have proven to be one of the company's competitive advantages through increased efficiency and productivity in production. TPS received much inspiration from the earlier reforms of Taylorism and Fordism from the rationalization movement. This through Taylor's ideas about standardization and Ford's running band principle. Toyota was also one of the first to design and apply the logistics theory’s Total Quality Management, Lean Production and Just-In-Time in its production system. Reforms used and well known in many companies, not least Scania and SPS. The report fulfilled its purpose through interviews and analysis of conceptual literature to find that there is a red thread within the company and that there is a clear link between SPS and previous reforms. In conclusion, we also managed to analyse and draw conclusions about how the SPS was designed, motivated and implemented. The design of SPS was achieved through close collaboration between Scania and Toyota wires, which enabled Scania to inspire and adapt the system to Scania's culture. The way in which SPS was motivated and implanted preceded a management process that Scania applied to within the organization. The solution came to be decisive for the future, leadership. A new way of thinking was applied throughout the business, which has proved to be successful.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
A Indústria Automotiva vem passando por grandes transformações que implicam em mudanças na Gestão de suas Cadeias de Suprimentos (Supply Chain Management - SCM). A acirrada competição existente no mercado globalizado vêm forçando as montadoras a buscarem novas vantagens competitivas. Diferentes modelos de produção de veículos vêm sendo introduzidos procurando alcançar nichos de mercado. Porém, o cliente ainda se vê obrigado a se satisfazer com a oferta de veículos disponíveis no mercado, que muitas vezes estão fora de suas reais necessidades e preferências. Além disso, os custos de imobilização de capital ao longo da Cadeia de Suprimentos continuam muito elevados. O autor desta dissertação procura então investigar os principais métodos e modelos de produção de veículos da Indústria Automotiva e esclarecer os conceitos de Customização em Massa e de Produção sob Encomenda (Build to Order – BTO), tendências que aparecem como alternativas para as montadoras de veículos aumentarem sua competitividade. O presente trabalho parte dos principais métodos de produção da Indústria Automotiva como a Produção Artesanal, a Produção em Massa e a Produção Enxuta destacando suas principais características, passa pelos modelos de produção procurando ressaltar as diferenças existentes entre eles, para, então, chegar aos conceitos, benefícios, desafios e outras particularidades das Tendências de Produção sob Encomenda e de Customização em Massa. A dissertação procura, finalmente, analisar os métodos e modelos de produção de veículos sob a ótica destas tendências.
The Automotive Industry has been going through great transformations that are calling for modifications in its Supply Chain Management (SCM). The huge competition on the current globalized market have been compelling the vehicles manufacturers to search for new competitive advantages. Different vehicles production models have been introduced in order to reach market niches. However, the customer is still obligated to be satisfied with the available vehicles in the market, which often do not match with their real needs and preferences. Besides, the cost of capital immobilization along the supply chain continues very high. The author of this dissertation wishes to investigate the main vehicles production methods and models in the Automotive Industry and to present the Mass Customization and Build to Order concepts, trends that come as alternatives to vehicles manufacturers to increase it competition. This work starts with the main production methods in the Automotive industry, as Handcraft Production, Mass Production, and Lean Production highlighting its. Then it covers the production models showing the differences between them and presents the concepts, benefits, challengers, and others particular characteristics of the Build to Order and Mass Customization trends. Finally, the dissertation analyses the vehicles production methods and models under these trends perspective.

Abstract:
To provide safety to domestic violence victims, law reform efforts provided victims with a civil remedy in which a judge orders the abuser to stay away from the victim. The research uses 1 rural county judicial system data to evaluate protective orders. Findings indicate that 42% of petitions are dismissed by petitioner's request or failure to prosecute. Moreover, court fees are not recouped in 79% of the cases. Logistic regression analysis indicate that an intimate relationship between the parties and payment of court costs by petitioner increased the probability of dismissal of petition upon petitioner's request; use of a gun and request to protect children increases the probability of applying the Brady Act; stalking and the issuance of the order of protection without social contact increased the probability of violations.

Machine tool industry is one of the key export industries in Taiwan, and it has been transformed from the previous regional industry into today's global industry in recent years. Though its main goal is to rapidly provide customers with satisfactory services, and also extends multi-site planning issues. And though these issues involve problems of supply chains between various sites such as assigning order, capacity planning, inventory management, its concepts are equivalent to that of production-inventory system. The scope of this research ranges from capacity reservation, order distribution, multi-site capacity planning and inventory control to suppliers’ inventory control, forming a multi level of production-inventory system. There is a high degree of standardization for the modules of machine tool products as well as a high level of technical standards; therefore, a suitable hybrid production plan is used in this research with the MTS/CTO mixed mode of production to increase the enterprises' competitiveness. In addition, because machine tools are expensive and unique, customers need careful assessments through many times of negotiation with the distributors; lengthy negotiations lead to potential order issue. The main purpose of this research is to construct a simulation model for production-inventory of multi-level supply chain under the factor of potential orders. In addition to a threshold value, it has a variety of policy-making combinations which includes capacity reservation strategy, order distribution strategy, multi-site capacity planning strategy, multi-site inventory strategy as well as supplier inventory strategy and other strategies. After simulating decision-making combination of multi-level supply chain through the model this research built, there are many indicators to measure production cost, order-filling rate, inventory costs in supply chain, and the contribution rate of working-hours. Hope that through this analysis and evaluation of various policies, enterprises could be more efficient with practical help.

This paper focuses on the probing area in wafer fabrication. Because wafer probing is the last operation in the front-end of wafer fabrication, the main planning target is due-date oriented. By considering multiple order priority and unstable production environment in the front-end process, the thesis constructs a production scheduling and planning model to satisfy the long-term target and to minimize the number of delay orders. This paper proposes two modules. The rough-cut capacity planning (RCCP) module considers the issue of process capability between orders and probing workstation and applies the capability-oriented loading allocation (COLA) algorithm [39] to allocate capacity of probing workstations to products in order to avoid unbalanced loading among workstations. Based on the planning results obtained, the master production schedule (MPS) module estimates relevant parameters such as average arrival rate to each workstation and throughput rate, etc. Then queuing theory model (M/M/c & M/D/c) is applied to estimate the production cycle time for each product and each rank. Based on the estimated results and the original due date of each order, the latest releasing time of each order can be determined. By considering the uncertainty of order arrival time and the remaining capacity of workstations, release sequence list is prepared for achieving on time delivery. Furthermore, for the orders that arrive after the latest releasing time, a modified due date will be calculated based on the actual releasing time, in order to promote on time delivery. Simulation results show that the proposed RCCP module can efficiently estimate the appropriate capacity loading for each workstation and the MPS module can estimate production cycle time and other relevant parameters. The entire system can provide effective and efficient planning results, which are valuable for decision making in shop floor production control.

Production planning, which allows the producer to manage all production activities efficiently, is a major issue in manufacturing/processing industries. A good plan helps the company lower down its expenses and/or increase the profit. This study considers a medium-term production planning problem in which a producer receives several periodic orders from multiple retailers at the beginning of planning horizon. Due to the capacity limit of the production system, the producer needs to reject some orders based on profit maximization principle. The producer faces two questions: 1) which order the producer should accept, and 2) when the products need to be allocated to the retailers. To solve these problems, we propose an integer programming model. Furthermore, due to the demand uncertainty, Fuzzy Set Theory is applied to construct a Fuzzy Chance-Constrained Production Mix Model so that the producer’s risk attitude and preference can be adopted to address uncertainty issue. Numerical examples for deterministic and uncertain cases are provided for illustration. The results of this study can help producers deal with a more realistic environment.

In the highly competitive environment, this thesis proceeds to design the Production Activity Control system with considerations of Multiple-Priority orders(PACMP)for the customer-oriented wafer fabrication. In order to meet the goals of on time delivery(OTD)and to maintain production performance steadily, this system not only has to handle the uncertain events(machine down, PM), but also to face the impact of multiple-priority orders existing in the shop. Hence, to design the PAC system, it needs to monitor performance targets for helping to achieve the goals such as OTD and load leveling. The PACMP consists of order release mechanism, dispatching mechanism, and production monitor system. Order release and dispatching mechanisms are executed basing on the developing of Two Boundary rule under loading and ranking considerations(LRTB). The LRTB applies the idea of the revised load-oriented two-boundary(LOTB), in which the physical WIP threshold is replaced with load threshold. Production monitoring system aims for providing necessary information so as to achieving planning targets. It has four subsystems, each with individual task as follows:due-date monitoring for meeting the on time delivery of layer throughput; load level monitor observes the load and order status of each critical resource. If monitor shows that no delay situation happens on any sub-layer of each order, then line balancing monitor is initiated for helping to make the actual load level close to the planned level through dispatching mechanism. Otherwise, the load effectiveness monitor is initiated for meeting the delivery times of sub-layers through dispatching mechanism. Load level of critical-resource monitor, line-balance monitor and load-effectiveness monitor are cooperated with each other for controlling the load level of critical resources. The case study shows that LRTB can reduce standard deviation and the range of product cycle time, which results from the WIP measuring in load so as to offset the weakness of using physical throughput and physical WIP level in TB+. Additionally, cooperating LRTB with production monitor system can help achieve throughput targets, shorten cycle times and improve delivery performance. Thus, the designed PACMP is applicable in customer-oriented wafer fabrication.

The urgent demands from customers, known as rush orders, often occur in job shops. Even though rush orders are quite common in job shops, most existing studies seldom discuss the economical justification of accepting such orders. Therefore, when rush orders arrive, decision-makers can only make decisions by their subjective views or by the rough estimation of the factory capacity. The justification of accepting such orders can be wrong and causes a great loss in profits.In this research, a heuristic model is proposed and developed to decide whether or not the rush orders should be accepted in job shops. In this model, a reward of accepting the rush order is compared with an extra cost of accepting the rush order. If the reward is greater than or equal to the extra cost, the rush order is accepted. Otherwise, the rush order would be rejected. The extra cost involves three cost items: work-in-process holding cost, carrying cost for early finish and penalty cost for late delivery. In order to verify this model, three non-controlled order acceptance methods are used to compare with this heuristic model. These three order acceptance methods are: (1) rejecting all rush orders, (2) accepting all rush orders and (3) randomly accepting rush orders. The results show the heuristic model is better than other non-controlled order acceptance methods.

The business core issue of an enterprise is to create its competitive advantage under the fast changes of customer desire. Based on the APS (Advanced Planning and Scheduling) perspect, this study is aimed to establish a system in order to provide a referenced decision-making platform under the current complicated environment. To combine the synchronized, real-time, comprehensive characteristics and the high computing capability of computer, this system is willing to integrate diverse products, deadline, production, material and inventory to deal with the deterministic order and the spot order situations under the considerations of the least cost with finite production capacity. This study not only considers the multi-product order, multi-factory production, multi-material purchase, diversed order deadline, production yield mean, product inventory cost, and production set-up cost, but also provides the material holding cost to construct an Integer Nonlinear Programming (INLP) mathematical model with the least cost. This model can function as a decision-making tool for focusing on the overall and real-time analyses of multi-order for multi-factory production planning. In addition, the proposed mathematical model is constructed by the syntax of Lingo 9.0 extended version, and then selects the built-in Global Slover as its solving method. A numerical example is then followed. This study creates a highly repeated characteristic because of the application of the package software (Lingo 9.0), and therefore it can treat as a valuable decision tool.

Very often in a manufacturing plant, an important job order must be processed with higher priority than other regular jobs. It will cause the production schedule change as well as the lead- time. This will affect the customer satisfaction and the business income. Therefore, it is vital for management to understand the impact on production performance of these emergent order. This thesis is to make a simulated comparison between MRP (push)and JIT(pull)system while they face emergency orders to understand their transient response towards the unexpected events. The during of the transient response will affect the level of customer service. Three segments can be divided for the response. The first segment(t1) is the response delay time between starting the emergent order and finishing of the first such processing. The second segment(t2)is the processing cycle time for the emergent order.t1 + t2 is the total processing time for the emergent order, i.e. the level of customer satisfaction. The third segment (t3 ) is the time for the system recover to steady state:it is the procedure for the delayed regular order. After the analysis, we found that the “pull” system takes more time than the “push” system in the initial response delay time while they face the emergent order. The total finished time for the emergent order, these two systems are nearly the same. It means that whichever you take does not make quite difference towards the customer service field. The distribution method will affect the duration for the system recover to steady state, the duration of pull system will be shorter while we utilize the exponential distribution of mean arrival rate and the mean service rate. While using normal distribution method the “push” system will be faster.

In the face of competition among the peers and ensuring the competitive advantage, the improvement of the factory has become increasingly important. In addition to the focus on product quality and cost reduction, the concept of delivery on-time is increasingly important. In order to improve competitive advantage, these are important such as increasing the speed of delivery, improving the production system, reducing production time to be less than other competitors, and achieving the best order fill rate. Therefore, this study uses system simulation software to improve the current plants own planning to obtain the best production capacity, which is a excellent choice for the industry to strengthen their own essence, to make a rapid response to customers, and to enhance competitiveness. This study takes the embossing wheel industry as a research case, analyzing the process of its production line. It provides the best factor level allocation suggestions in the research results. Firstly, the simulation construction of case production mode is carried out with Arena system simulation software, using six long time workstations are as experimental factors, also choosing the order fill rate and production time as the two reaction variables of the study. Secondly, using the factor configuration of the 2^(6-2) factor experimental design to simulate the production line, and collect the data. Thirdly, the output data is analyzed by the Minitab statistical analysis software to get the best configuration of the factor level. Finally, let the data verified by extending the number of simulations for various configurations. In order to assess the reliability of the simulation model is adequated, adding the sensitivity analysis is an important part. The mode’s stability is proved by lengthening the simulation time and increasing the number of simulations. Then, if you use this study’s optimal level configuration of the experimental factors , the output performance values of the reaction variables Y1 (order fill rate) and reaction variable Y2 (average production time) will also be the best output values.

In this study, we consider a production system with hybrid MTO (make-to-order) and MTS (make-to-stock). Corresponding to customers’ demand, bottleneck machine of this production system may be shifting. To deal with the environments mentioned-above, we present an algorithm to make the decision rule about releasing and dispatching to enhance the delivery-rate of MTO and the outputs of MTS. To avoid the bottleneck idling, we develop a time window- starvation avoidance (TW-SA) rule to release the MTS lots timely. The MTO lots have the higher priority than the MTS lots in every work shop, besides that the bottleneck is going to idle. When the WIP level before the bottleneck machine is lower than the threshold, the dispatching priorities among MTS lots are determined by SABT dispatch rule. Otherwise, the dispatching priorities are determined by the SRPT dispatch rule. Simulation results show that the delivery-rate for MTO products, a high output-rate for MTS products, and a small difference between input-rate and output-rate for MTS products of the proposed algorithm are better than other representative algorithm in literature.

With the trend of global competition, in order to respond effectively to market demand for fast and complex, and reduce the bullwhip effect on the impact caused by the overall supply chain, the key for successful enterprise is how to get the most complete information fast, and then grasp the real needs of customers. For enterprise, many of these suppliers, the problem of how to plan the purchase order is more important, not only have to master the resource planning of the situation, but must give full play to the function of allocating resources, and taking into account the final product to ensure the quality and costs. In this study, planning procurement order properly and effectively,and meet customer needs on the premise that establish a purchase order planning decision support system with pull system to help the procurement of components allocate to suitable supplier, and that can satisfied the number of defective products in imperfect process. Those either can provide reasonable price or Improve product quality with encourage producers and suppliers to reduce costs and increase profits. We find, how to allocate order to minimize the total cost of production that according to the order allocation rule in group of 100 test cases. In the first strategy, the average cost is 100% similarity, variation is 0, and the average savings time is 95.41%; In the second strategy, the average cost is 99.79% similarity, variation is 0.002%, and the average savings time.is 95.64%. The strategy and rules of purchase order distribution have obtained the lowest total cost of production with excellent efficiency, and can provide the best approximation of a purchase order planning for decision-makers in the shortest time, and thus enhance corporate profit and competition force.
