The application of computers in the manufacturing industry has substantially altered the control procedures used to program a whole manufacturing process. Currently, one the problems which automated manufacturing systems are experiencing is the lack of a good overall control system. The subject of this research has been centred on the identification of the problems involved in current methods of control and their advantages and disadvantages in an automated manufacturing system. As a result, a different type of control system has been proposed which distributes both the control and the decision making. This control model is an hybrid of hierarchical and hierarchical control systems which takes advantage of the best points offered by both types of control structures. The Durham FMS rig has been used as a testbed for an automated manufacturing system to which the hybrid control system has been applied. The implementation of this control system would not have been possible without the design and development of a System Integration Tool (SIT). The system is capable of real-time scheduling of the system activities. Activities within the system are monitored in real-time and a recording of the system events is available, which allows the user to analyse the activities of the system off-line. A network independent communication technique was developed for the Durham FMS which allowed the manufacturing cells to exercise peer-to-peer communication. The SIT also allowed the integration of equipment from different vendors in the FMS.

Additive manufacturing (AM), sometimes called 3D-printing is a group of manufacturing technologies that build up a product using a layer by layer technique and provides new ways of manufacturing parts and products. The Company in this thesis wants to make AM a tool in their manufacturing toolbox. When introducing this manufacturing method, new processes and methods have to be developed. The purpose of this thesis is to develop a methodology that will help the designers when identifying parts that should be manufactured using AM. The development of this methodology has followed the principles of service design which is a holistic interdisciplinary approach where methods from different disciplines are combined to create benefits to the end user experience. Before the development process, a large background study was performed to gather detailed information within the area of AM. The methodology concept was then developed through five iterative cycles where methods such as interviews, trigger material, questionnaire, case study and stakeholder mapping were used. The thesis resulted in an AM handbook with information regarding the technology and a five step methodology for choosing when and why to use AM as a manufacturing method. Step one is to identify the AM potential in a product which is based on complexity, customization and production volume. Step two is to specify requirements of the products, this can be surface finish, tolerances etc. The third step in the design methodology is part screening, which is the making of the final decision about if the product should be printed and if it can be printed. The fourth step is to choose an AM technology based on the requirements specified in step two by providing information about the technologies’ restrictions and possibilities. Step five in this methodology is the design of AM products and provides simple design guidelines. It has been shown that a dynamic task is best solved through working with dynamic methods, therefore service design approach is a flexible and good fit for this thesis. This design methodology is only a part of the AM-area and needs to be supplemented with other knowledge within the area. The first step after implementing this handbook is to investigate how the organization and business is affected when implementing AM.
Additiv tillverkning (AM), även kallat 3D-printing, är benämningen på en grupp tillverkningstekniker där en produkt byggs lager för lager. Denna masteruppsats har utförts i samarbete med ett svenskt industriföretag som levererar lösningar inom tillverkningsindustrin, i rapporten kallat Företaget. Genom att utveckla nya designprocesser och metoder vill Företaget inkludera AM i sin tillverkningsstrategi. Syftet med detta masterexamensarbete var att utveckla en metodik för hur urval och utveckling av produkter anpassade för AM ska ske. Utvecklingen av metodiken följer principerna för tjänstedesign, vilket innebär ett holistiskt tvärvetenskapligt arbetssätt där metoder från olika discipliner kombineras för att skapa en positiv upplevelse för slutanvändaren. Innan utvecklingsprocessens start gjordes en stor bakgrundsstudie för att införskaffa kunskaper kring AM. Därefter utvecklades en metod genom fem iterativa cykler där metoder som intervjuer, triggermaterial, frågeformulär, fallstudier och stakeholdermapping användes. Masteruppsatsen resulterade i en handbok med information kring teknikerna och en metodik i fem steg för att välja när och varför AM bör användas som tillverkningsmetod. Första steget är att identifiera AM potentialen hos en produkt, vilket baseras på komplexitet, kundanpassning och produktionsvolym. I steg två ska produktkrav specificeras, exempel på sådana krav är ytfinhet och toleranser. Tredje steget i metoden handlar om en produkt-undersökning under vilken ett slutgiltigt beslut fattas angående om produkten kan och bör tillverkas. I fjärde steget sker valet av teknik baserat på de produktkrav som specificerats i steg två, genom att information ges angående teknikens möjligheter och begränsningar. Femte steget i metoden handlar om designen av AM produkter och förser konstruktören med enklare riktlinjer för designen. Utveckling av en metodik kräver ett dynamiskt arbetssätt och principerna inom service design visade sig passa bra för detta projekt. Det visade sig också att den resulterade metodik behöver kompletteras med information i framtiden. Det behövs även fastställas tydliga mål för AM i företaget och vilket syfte implementeringen av denna nya process innebär

For many people in developing contexts, the financial expense of construction can be overwhelming. There is a need for more appropriate technologies for low-cost construction. This thesis presents a concise review of construction technologies and then offers a design methodology for creating curved, interlocking brick geometries that can be produced more accurately than existing bricks. The increase in dimensional accuracy is able to dramatically reduce the cost of construction in developing areas. A design is then offered for a low-cost press for these brick geometries that can be produced by local fabricators in developing areas.

Les systèmes de production sont devenus des systèmes de grande échelle dont la complexité est accentuée par des contextes marqués de plus en plus par le changement. La capacité des systèmes a répondre au changement – appelée également changea-bilité – est reconnue comme étant une propriété essentielle pour leur cycle de vie, aussi bien dans le domaine des systèmes de production que dans le domaine de la conception en ingénierie. Au regard de la complexité des systèmes de production changeables, la méthodologie proposée par cette thèse a pour objectif de supporter la change-abilité dans la conception en souscrivant au domaine de l’ingénierie des systèmes. La première contribution est un formalisme pour la modélisation des systèmes changeables étayé d’après les principes de la conception systémique. Les concepts de flexibilité et de reconfigurabilité ne sont ici pas limités à des composants organiques du système, mais englobent l’ensemble des artefacts d’ingénierie dans le domaine du problème (exigences) et le domaine de la solution (blocs structurels). La deuxième contribution est une méthodologie pour la conception et la gestion des systèmes changeables. Elle repose sur un modèle du cycle de vie des systèmes changeables où des phases de conception des capacités de change-abilité du système s’alternent avec des phases de reconception tirant bénéfice de ces capacités existantes. Ces processus complémentaires garantissent la cohérence entre les décisions de conception pour intégrer et réutiliser des capacités de change-abilité, augmentant alors leurs potentiels tout au long du cycle de vie des systèmes complexes. Les concepts et les méthodologies développés ont été validés par des projets de conception de systèmes de production chez un équipementier automobile. Enfin, des développements possibles d’outils d’aide à la conception supportant la méthodologie proposée sont discutés
Manufacturing systems have become large scale systems with increasing complexity particularly magnified by highly changing contexts. The system’s ability to cope with change (i.e. changeability) is recognized as a critical lifecycle property in the manufacturing system and engineering design domains. Given the complexity of changeable manufacturing systems, the proposed methodology of this dissertation aims to support design of changeability in subscribing to the domain of system engineering. The first contribution is a formalism for modeling changeability in a systemic way. Flexibility and reconfigurability paradigms are not limited to physical components of the system, but to the overall system architecture that encompasses all engineering artifacts relating to the designed system in both the requirements and physical solution domains. The second contribution is the methodology for the design and the management of changeability. The methodology utilizes a lifecycle model for changeable systems, in which design for changeability phases alternate with re-design phases that embrace and benefit from the existing changeability capabilities. These complementary processes allow a better consistency between design decisions to embed and reuse changeability, increasing changeability potential during the lifecycle of complex systems. The developed concepts and methodologies are validated in manufacturing system design projects from an automotive supplier. Finally, perspectives on design tools assisting the proposed methodology are discussed

This research concerns the development of a risk analysis and mitigation methodology for assessing the impact of uncertainties and complexity of the design requirements arising in new process and product developments in micro and nano manufacturing. The risk analysis methodology integrates different computational approaches for process and product analysis, including the reduced order modelling using design of experiments, risk analysis using sampling-based and analytical methods and optimisation techniques. The integrated risk analysis and optimisation methodology is applied to two applications: (1) the FIB sputtering process control, and (2) a flip chip design. Three different FIB processes using different ion sources were investigated in order to evaluate their process performance with respects to different process parameter uncertainties. A critical comparison of the process capability against the specification limits of different processes was studied. As parts of the research, a new modified computational model is developed for a material sputtering process using focused ion beam (FIB). This model allows the analysis of micro- and nano-structures shape with the FIB machine controlled through multiple beam scans and different beam overlapping. The FIB model related studies also address the modelling requirements for including material re-deposition effects that occur during FIB milling. The model has been validated using an experimental test case. Good agreement is observed between the analytical shape using the model and the actual experiment. The validated model enhances the accuracy of the dwell time prediction. This approach overcomes the dependence of a trial-and-error approach of the process control in nano-manufacturing industry. The proposed methodology is also used to address a design problem of a flip chip design. A novel method for the evaluation of the environmental impact of the flip chip design in a multi-disciplinary optimisation problem is proposed. The goal is to address materials constraints due to environmental regulations and to handle different types of requirements such as the reliability and cost. An optimal flip chip design reliability function is identified. The approach allows electronics manufacturers to consider the environmental impact amongst different design alternatives at an early stage of the design of the product before any real prototyping in order to reduce the total manufacturing life cycle.

The need for improvements in the construction industry in the UK has been reported through a succession of Government and Institutional reports, illustrating the problem areas. The area of project processes in manufacturing has been found to have great similarities with its equivalent (design and construction) in the construction industry. This has led to co-ordinated efforts in improving the construction industry project processes by considering 'Construction as a Manufacturing Process.' Those efforts concentrated in adapting the manufacturing project process elements into construction. However, the methodology needed to adapt those processes has not been considered. This was presented as an opportunity to develop an original and novel methodology for the Adaptation of MAnufacturing Project Processes Into Construction (AMaPPIC). The aforementioned need combined with the author's experience in both the manufacturing and construction industries were the catalysts for the formulation of the research. A case study research strategy was used to undertake the research, for the discovery, building and testing of the AMaPPIC methodology. A number of research methods were employed to collect data for the research. The necessary literature in business process management, manufacturing NPD (new product development), and design and construction was combined with a number of informing case studies for the discovery and building of the AMaPPIC methodology. The methodology consists of 14 stages, which consider the identification and demonstration of a need for adapting project processes into construction to the final 'existence' and continuous improvement of the adapted process within an organisation. The GPT case study was used to test the AMaPPIC methodology in a 'live' project within the company. The results of the case study were used to further define and improve the methodology by examining its applicability in the Poole project. The resulting AMaPPIC methodology provides an original, prototypical solution to adapting manufacturing project processes into construction.

In the face of rapid development in information technology coupled with a growing dynamism in global markets, manufacturing systems have to be re-constructed for short term or long term goal. Such innovations promise to lead to a new competitive stage, which typically involve design of function, information and behaviour of systems. In order to design the system, simulation has often been chosen. However, simulation has proved limited and fails to aid design of such a complex systems because of consuming much computing time and cost, especially when modelling larger systems. Thus, there is a need to seek a new approach, in a way that results in simulating such a large manufacturing system with less demand on computing time and cost. This study researches into a hybrid modelling approach to minimise these limitations. It includes proposing a hybrid modelling methodology and developing a hybrid modelling tool. The methodology integrates simulation and metamodelling techniques. The metamodel employed in the study possesses, not only characteristics of conventional metamodels in terms of representing relationships in quantity, but also in time lapse. This is the originality of the study and the significant distinction between this research and application of metamodelling in conventional ways. The hybrid modelling tool is developed to support and demonstrate the identified hybrid methodology. LISP has been used as the software language for the hybrid modelling tool. The result of this work concludes that the hybrid modelling approach is capable of simulating a complex manufacturing system with less demands on the computer. The work reported in this thesis has been carried out in conjunction with the EPSRC research project, Hierarchical Manufacturing System Modelling (HMSM) (GR/F96549), to produce an Integrated Design and Modelling Methodology (IDEM). The project was initially a collaborative research program including Loughborough University of Technology (LUT), Morris Crane Ltd., of Loughborough and GEC Large Machine, of Rugby. The experience of these collaborators has proved most valuable in supporting the research, and have provided a cross section of views and comments. The research reported in this thesis is set in the context of the HMSM Research group at Loughborough.

The requirement and awareness of the carbon emissions reduction in several scales and application of sustainable manufacturing have been now critically reviewed as important manufacturing trends in the 21st century. The key requirements for carbon emissions reduction in this context are energy efficiency, resource utilization, waste minimization and even the reduction of total carbon footprint. The recent approaches tend to only analyse and evaluate carbon emission contents of interested engineering systems. However, a systematic approach based on strategic decision making has not been officially defined with no standards or guidelines further formulated yet. The above requirements demand a fundamentally new approach to future applications of sustainable low carbon manufacturing. Energy and resource efficiencies and effectiveness based low carbon manufacturing (EREEbased LCM) is thus proposed in this research. The proposed EREE-based LCM is able to provide the systematic approach for integrating three key elements (energy efficiency, resource utilization and waste minimization) and taking account of them comprehensively in a scientific manner. The proposed approach demonstrates the solution for reducing carbon emissions in manufacturing systems at both the machine and shop floor levels. An integrated framework has been developed to demonstrate the feasible approach to achieve effective EREE-based LCM at different manufacturing levels including machine, shop floor, enterprise and supply chains. The framework is established in the matrix form with appropriate tools and methodologies related to the three keys elements at each manufacturing level. The theoretical model for EREE-based LCM is also presented, which consists of three essential elements including carbon dioxide emissions evaluation, an optimization method and waste reduction methodology. The preliminary experiment and simulations are carried out to evaluate the proposed concept. The modelling of EREE-based LCM has been developed for both the machine and shop floor levels. At the machine level, the modelling consists of the simulation of energy consumption due to the effect of machining set-up, the optimization model and waste minimization related to the optimized machining set-up. The simulation is established using sugeno type fuzzy logic. The learning method uses on experimental data (cutting trials) while the optimization model is created using mamdani type fuzzy logic with grey relational grade technique. At the shop floor level, the modelling is designed dependent on the cooperation with machine level modelling. The determination of the work assignment including machining set-up depends on fuzzy integer linear programming for several objectives with the evaluation of energy consumption data from machine level modelling. The simulation method is applied as the part of shop floor level modelling in order to maximize resource utilization and minimize undesired waste. The output from the shop floor level modelling is machine production a planning with preventive plan that can minimize the total carbon footprint. The axiomatic design theory has been applied to generate the comprehensive conceptual model E-R-W-C (energy, resource, waste and carbon footprint) of EREE-based LCM as a generic perspective of the systematic modelling. The implementation of EREE-based LCM on both the machine and shop floor levels are demonstrated using MATLAB toolbox and ProModel based simulation. The proposed concept, framework and modelling have been further evaluated and validated through case studies and experimental results.

Manufacturing industries rely on automated manufacturing systems to improve the efficiency, quality and flexibility of production. Such systems typically consist of a variety of manufacturing machinery and control hardware, e.g. CNC machine tools, robots, PCs, Programmable Logic Controllers (PLCs) etc., which operate concurrently. The cost of developing and implementing an automated manufacturing system is high, and is particularly so if the control system is found to be unreliable or unsafe during operation. Distributed Control Systems are generally used to control complex concurrent systems,At present the methods used to develop DCSs tend to follow a sequence of steps, viz. a statement of the requirements of the DCS, a functional specification of the DCS, the design of the DCS, generation of the software code for the DCS, implementation of the software. This step approach is inadequate because of the dissimilarity of techniques used to represent each step, which leads to difficulties in ensuring equivalence between the final implementation of the DCS and the initial requirements, which in turn leads to errors in the final software. To overcome this, work has been conducted to unify the specification, design, and software coding phases of the DCS development procedure by ensuring formal equivalencies between them. One particular outcome of such previous work is a tool named Petri Net - Occam Methodology, developed by Dr. P. Gray, which produces dependable Occam code for DCSs. Gray's methodology produces readable designs, directly from the specification of systems, in a graphical but formal way, and results in a Petri Net graph which is equivalent to the final Occam code. However, his methodology is not for a complete DCS but only for one containing Transputers. The PLC is widely used in industry and an integral part of DCSs for Automated Manufacture. This research has developed a methodology, named PNPLC, which produces dependable PLC control programs, in a graphical but formal way, directly from a system's specification. It uses the same tool, Petri Nets, for both designing and simulating the control system, and specifies rules which ensure the correct design, simulation and encoding of PLC programs. The PN designs are a one-to-one equivalent to PLC code and can be directly translated into Ladder Diagrams. Therefore if the simulation shows the design to be correct, the final software will be correct. PNPLC works as a stand alone tool for developing dependable PLC control programs, and also unifies with Gray's methodology to produce a complete tool for developing a resilient DCS containing Transputers and PLCs. The unification of the two methodologies is also reported in this thesis. The research work presented in this thesis contributes to knowledge in the field of DCS development. Recommendations for further work regarding the applicability of the unified methodology on a wide scale industrial basis are also given.

Magnetic components such as inductors and transformers are generally the largest circuit elements in switch-mode power systems for controlling and processing electrical energy. To meet the demands of higher conversion efficiency and power density, there is a growing need to simplify the process of fabricating magnetics for better integration with other power electronics components. The potential benefits of additive manufacturing (AM), or more commonly known as three-dimensional (3D) printing technologies, include shorter lead times, mass customization, reduced parts count, more complex shapes, less material waste, and lower life-cycle energy usage—all of which are needed for manufacturing power magnetics. In this work, an AM technology for fabricating and integrating magnetic components, including the design of manufacturing methodology and the development of the feedstock material, was investigated. A process flow chart of additive manufacturing functional multi-material parts was developed and applied for the fabrication of magnetic components. One of the barriers preventing the application of 3D-printing in power magnetics manufacturing is the lack of compatible and efficient magnetic materials for the printer's feedstock. In this work, several magnetic-filled-benzocyclobutene (BCB) pastes curable below 250 degree C were formulated for a commercial multi-material extrusion-based 3D-printer to form the core part. Two magnetic fillers were used: round-shaped particles of permalloy, and flake-shaped particles of Metglas 2750M. To guide the formulation, 3D finite-element models of the composite, consisting of periodic unit cells of magnetic particles and flakes in the polymer-matrix, was constructed. Ansoft Maxwell was used to simulate magnetic properties of the composite. Based on the simulation results, the pastes consisted of 10 wt% of BCB and 90 wt% of magnetic fillers—the latter containing varying amounts of Metglas from 0 to 12.5 wt%. All the pastes displayed shear thinning behavior and were shown to be compatible with the AM platform. However, the viscoelastic behavior of the pastes did not exhibit solid-like behavior, instead requiring layer-by-layer drying to form a thick structure during printing. The key properties of the cured magnetic pastes were characterized. For example, bulk DC electrical resistivity approached 107 Ω⋅cm, and the relative permeability increased with Metglas addition, reaching a value of 26 at 12.5 wt%. However, the core loss data at 1 MHz and 5 MHz showed that the addition of Metglas flakes also increased core loss density. To demonstrate the feasibility of fabricating magnetic components via 3D-printing, several inductors of differing structural complexities (planar, toroid, and constant-flux inductors) were designed. An AM process for fabricating magnetic components by using as-prepared magnetic paste and a commercial nanosilver paste was developed and optimized. The properties of as-fabricated magnetic components, including inductance and DC winding resistance, were characterized to prove the feasibility of fabricating magnetic components via 3D-printing. The microstructures of the 3D-printed magnetic components were characterized by Scanning-electron-microscope (SEM). Results indicate that both the winding and core magnetic properties could be improved by adjusting the formulation and flow characteristics of the feed paste, by fine-tuning printer parameters (e.g., motor speed, extrusion rate, and nozzle size), and by updating the curing profile in the post-process. The main contributions of this study are listed below: 1. Developed a process flow chart for additive manufacturing of functional multi-material components. This methodology can be used as a general reference in any other research area targeting the utilization of AM technology. 2. Designed, formulated and characterized low-temperature curable magnetic pastes. The pastes are physically compatible with the additive manufacturing platform and have applications in the area of power electronics integration. 3. Provided an enhanced understanding of the core-loss mechanisms of soft magnetic materials and soft magnetic composites at high frequency applications.

Computer simulation is a well-established decision support tool in manufacturing industry. However, factors such as wrong conceptualisation, inefficient input data modelling, inadequate verification and validation, poorly planned experimentation and lengthy model documentation inhibit the rapid development and deployment of simulation models. A serious limitation among the above factors is inefficient data modelling. Typically, more than one third of project time is spent on identification, collection, validation and analysis of input data. This study investigated potential problems which influence inefficient data modelling. On the basis of a detailed analysis of data modelling problems, the study recommends a methodology to address many of these difficulties. The proposed methodology, discussed in this thesis, is called MMOD (Methodology for Modelling Of input Data). An activity module library and a reference data model, both developed using the IDEF family of constructs, are the core elements of the methodology. The methodology provides guidance on the best way of implementation and provide a tool kit to accelerate the data modelling exercise. It assists the modeller to generate a customised data model (entity model), according to the knowledge gained from the conceptualisation phase of the simulation project. The resulting customised data model can then be converted into a relational database which shows how the entities and relationships will be transformed into an actual database implementation. The application of the MMOD through simulation life cycle also enables the modeller to deal with important phases in the simulation project, such as system investigation, problems and objective definitions and the level of detail definitions. A sample production cell with different level of detail has been used to illustrate the use of the methodology. In addition, a number of useful methods of data collection and the benefits of using a MMOD approach to support these methods and data rationalisation which accelerates the data collection exercise are also covered. The aim of data rationalisation is to reduce the volume of input data needed by simulation models. This work develops two useful data rationalisation methods which accelerate the data collection exercise and reduce the model complexity. This work produced a novel approach to support input data modelling in simulation of manufacturing system. This method is particularly useful when the complex systems are modelled.

This research has highlighted the importance of the multiple roles in design and change organizations and the benefits to have quantitative tools and qualitative tools to support decision making. Hence the aims and objectives of this research are a model driven approach to support integrated decision making in MEs. The author has identified a gap in the lack of a systematic way to model MEs to facilitate integrated decision making. Initial Modelling Methodology (IMM) has been established based on Manufacturing System Integration (MSI) group at Loughborough University so that improvement of this methodology can be investigated to facilitate integrated decision making. Artwork is an industrial furniture manufacturer based in Loughborough and is used as the company case study of this research. IMM has been tested in exploratory research case 1 at a low level of production at Artwork. The experimentations of case 1 have been carried out to study the impact of product volume and variety on specific process section at low level. The result has shown that IMM lacks the ability to facilitate integrated decision making aspect and it can be developed to achieve aims and objectives. This leads to additional concepts of (1) modelling at different level of abstraction to realise the benefit of multiple levels of modelling, (2) deploying the improved views of W, P and R sub-systems to assist in exercising simulation modelling and (3) identifying possible users in planning with scope and focus of decision making. These three concepts were added into IMM and known as Extended Modelling Methodology (EMM). The EMM has been tested in exploratory research case 2 at a mid-level of production system at Artfrom with four types of experimentations: 1) balancing resources of production system, 2) demand change, 3) rework impact and 4) delay impact. The evaluation of results has shown a systematic way of the EMM to facilitate decision making individually and collectively. Therefore the overall research contributions are a new model driven approach to support conceptual design and change of manufacturing systems in aspect of integrated decision making. However, limitations of this research can be addressed as limited availability of data, range and detail of case studies and limited range of modelling techniques explored here. It follows that scopes of future works are utilization of EMM in other domains, consideration of other reference models, investigation of EMM in other company case studies and establishment of a comprehensive database applied in EMM and development of coherent simulation models. In addition, this thesis has also presented ongoing research on developing and testing EMM in another company case study in aircraft engine manufacturer.

Flexible, modular, continuous manufacturing small-scale plants (MCSPs) for small-molecule drugs have been recognized as potential safe and economical solutions for pharmaceutical manufacturing. However, among the variety of equipment technologies required for an MCSP platform, there are only a few technologies that have publicly available methodologies for equipment selection. In this study, a new method and tool for computer-assisted equipment selection was developed, which use key engineering correlations and design criteria to match off-the-shelf equipment with the synthesis processes of interest. Furthermore, the tool allows simultaneous equipment selection for multiple synthesis processes to allow the identification of the most flexible MCSP assets. The long-term goal of this tool is to encompass the entire span of technologies that could be used in an MCSP skid and to serve as a communal storage location for vendor-available equipment information to facilitate collaboration and design of a mainstream continuous manufacturing (CM) system. This methodology was applied to equipment selection for the continuous manufacturing of an actual Amgen small-molecule drug substance (API) as a case study. The results from this study showed that the new tool can improve the speed at which equipment is selected and can aid the process developer in decision-making for choosing the most suitable CM asset.

Manufacturing companies find themselves, whether they like it or not, in a more global and changing reality. Fiercer competition, dynamic markets, new consumer habits, stronger environmental regulations, and new technological possibilities, are forcing manufacturing companies to change. The practical effects for European manufacturers are 1) new and innovative products, 2) global value chains, 3) automation, and, 4) a shift from products to solutions. This research is addressing the changes needed for operations in a single enterprise (a group of departments, a plant, or a group of closely located plants), to take advantage of the competitive situation.

For such “internal” operations, the new challenges require changes both in technology and practices. The main concern of this research is the practices, and how a reengineering of manufacturing and office operations can improve performance. The choice of scope is based on the assumption that operations activities are a major source for competitiveness. To reengineer operations activities in processes rather than functions, and to implement best practices wherever appropriate, can therefore provide dramatic competitive improvements.

The overall objective of this research is to:

• establish enterprise reengineering as an approach that enables manufacturing enterprises to achieve fit between market requirements and operations capabilities.

Enterprise reengineering is viewed as model-based and strategy driven approach that enables manufacturers to realise the “soft” or infrastructural aspects of an operations strategy. To support such reengineering efforts, enterprises are viewed not only from a process perspective but also from a resource, materials, information, organisations, and control perspective. Modelling and analysing enterprises from these perspectives can support their effort to implement best practices, and ensure that the practices are combined in a way that supports the overall business strategy.

The overall objective is divided into more specific objectives:

• To develop a strategic framework for enterprise reengineering

• To develop a consistent and practical enterprise reengineering methodology to support the formulation and realisation of operations strategies

• To develop architecture for conceptual enterprise modelling that ensures a coherent, decomposed, and holistic picture of enterprise operations

• To establish “flow manufacturing” as a (optional) best practice programme for enterprise reengineering

Together, the strategic framework, the methodology, and the modelling architecture should enable enterprises to achieve their performance objectives through an enterprise reengineering effort. In cases where an enterprise mapping and analysis concludes that improvements in manufacturing planning and control, order management, layout and flow, or inventory, should be performed, the flow manufacturing programme should provide practical guidance and a set of principles to support reengineering.

In order to achieve these objectives, the following issues are reviewed in this thesis:

1) operations strategy, 2) enterprise reengineering, 3) flow manufacturing, 4) enterprise modelling, and, 5) change management. Based on these literature studies, a strategic framework, a methodology, a modelling architecture for enterprise reengineering and a flow manufacturing programme are proposed.

The major outcome of this research is an enterprise reengineering methodology, which includes strategic planning, and operations mapping, analysis, design, and implementation. The methodology consists of the following models, principles, and tools:

• A operations strategy checklist

• Four flow manufacturing design principles

• An architecture for conceptual enterprise modelling

• Seven change management principles

• A procedural guide for enterprise reengineering

• An operations performance audit sheet

• A five-step approach to flow manufacturing reengineering

The research is based on a case study of HÅG Fast, a very successful enterprise reengineering project carried out in 1991-1992. The case study demonstrates the usefulness of the methodology to analyse and understand enterprises, and the dramatic improvements in performance that can be achieved by implementing flow manufacturing practices. In addition, the enterprise reengineering methodology has been proved useful in several field studies.

Organisations can deploy Total Quality Management (TQM) through company quality programmes in order to achieve improved business performance. A review and analysis of TQM literature found that the areas of strategic quality management, quality practices and quality activities (tools and techniques) have evolved largely independently without relationships being established. Employee involvement (EI) is a key element of TQM yet the involvement of individuals in specific quality activities is an under-researched topic. The aim of this research is to propose a framework which links these areas and provides a methodology for manufacturing organisations to use to link quality activities to strategic quality requirements and therefore facilitate the management of their quality programme. Exploratory case study research has underpinned the research methods adopted. Information about the deployment of TQM through quality programmes via quality practices and quality activities was gathered through interviews, documentation and surveys. Specific details regarding the actual quality activities engaged in by individuals were obtained by participant observation. The data was evaluated both within case and cross case using a selection of methods. Findings have resulted in the creation of two unique frameworks. The first, the Quality Programme, Quality Activities and Performance (QPQAP) framework, provides a structure to link strategic quality requirements to quality activities via performance measures and includes a feedback process to facilitate continuous improvement and sustain the quality programme. Quality Function Deployment (QFD) has been adapted to deploy the QPQAP Framework and an analysis process developed. The second framework describes an Activity Classification System (ACS) that can be used to categorise and analyse an individual’s day-to-day quality activities and judge the application and effectiveness of these activities. Combined, these frameworks provide a Quality Programme Management Framework which enables organisations to make decisions about the application of quality activities and adjustments necessary to improve performance and fulfil strategic quality requirements.

This research addressed two very fundamental issues in cellular manufacturing. These two issues were organizational feasibility for the implementation of cellular manufacturing and the choice of method approach for part-family/machine grouping if feasibility was adjudged, given organizational and manufacturing characteristics. The approach to part-family/machine grouping may follow one of the following options—a design-oriented approach, a production-oriented approach, or a combination of both. An examination of published literature, in English, on cellular manufacturing indicated the need for this research. A methodology was developed to address the above issues. A Conceptual Flow Model (CFM) was first developed to structure and rationalize the research problem. The concept of the CFM originated from the basic input-output production model in literature. This model helped the formulation of the research problem by rationalizing that a new manufacturing approach, cellular manufacturing, was feasible for an organization if certain performance measures were weak and if certain criteria regarding the products, available resources, procedures used, and organizational characteristics were met. On the other hand, the model proposed that an organization could remain functionally arranged and improve its existing procedures for better performance if these criteria were not met. This work, however, did not include this latter part of the model as a research issue. Once feasibility for the implementation of cellular manufacturing was adjudged, the model hypothesized that a part-family/machine grouping approach was necessary for the initial design of the cells. This approach was to be selected from the design-oriented approach, the production-oriented approach, or a combination of both. This model formulation enabled the identification of important attributes pertinent to the research problem. The attributes were identified through a comprehensive review of applicable literature in cellular manufacturing. The attributes for the feasibility issue were clustered into four categories. These were the products and processes category, the resources category, the procedures category, and the organizational characteristics category. The attributes pertinent to the choice of method issue were clustered into the product category, the resources category, and the objectives category. The identification of the attributes was followed by an explanation of their relevance. A set of propositions was developed next to relate the level of an attribute to the feasibility for the implementation of cellular manufacturing and the choice of method issues. The propositions further strengthened the theoretical background of this research through the use of past research and enabled the construction of the rules necessary for resolving the choice of method issue. A complete set of definitions and specifications was then developed for each of the attributes for both issues. The purpose of the specifications was to enable the measurement of the attribute levels through developed measures of each attribute. All the attributes were weighted according to their perceived importance. A scoring model was developed to determine a score for feasibility for cellular implementation. This score represented a calculated measure of an organization’s feasibility for the implementation of cellular manufacturing. A rule-based procedure was developed to determine the choice of method for part-machine grouping. To verify the relevance of the attributes, their measures and weights, and (indirectly) the propositions, companies engaged in cellular manufacturing were visited and data pertinent to the feasibility analysis and choice of method procedures were collected. Valuable information was gained from these visits, and it was found that some attribute measures will require possible refinement in future research. This field research also indicated the possibility of refinement of the feasibility matrix constructed from the feasibility analysis procedure. Certain attributes pertinent to the choice of method procedure also may require refinement in future research. For comparison purposes, data were also collected from a company with a functional layout and used with the scoring model. In summary, the objective of developing a framework for determining organizational feasibility for the implementation of cellular manufacturing and the choice of method approach for part-family/machine grouping if feasibility was adjudged, given organizational and manufacturing characteristics, was undertaken. The framework was developed and its components verified through field work.

Reduction of emissions and utilization of energy are topics that have been widely discussed in the recent past. In order to align with the aim of several manufacturing companies to reduce their emissions, the development of a carbon footprint quantification tool is very desirable. Such a tool can be instrumental in identifying and evaluating areas of improvement within their entire supply chain. This thesis attempts to create a tool to calculate the product carbon footprint in a manufacturing environment, by taking up a case at a company that manufactures cylindrical pins at Järna, Sweden. This thesis project attempts to break down the processes involved in the manufacturing process and decipher the individual contributions each process makes to the product carbon footprint. Such a tool, used to quantify the greenhouse gases consumed or emitted by a product over a particular period of time would require a collaborative effort from the management at the company and their suppliers to retrieve all the requisite data from the processes. Furthermore, in order to ensure a holistic ecological assessment of a product catalogue, a comprehensive study of all primary and secondary activities in the facility was conducted. In addition to creating the carbon footprint calculator, a key aspect of this project was to investigate the different public declarations of carbon footprint and the methodologies of calculating the emissions in similar environments. The tool curated using the aforementioned data is used to calculate the product carbon footprint of some products manufactured at the facility to eventually identify methods of improving the ecological performance of the company while understanding the salient features a carbon footprint calculator must have in order to operate efficiently in other facilities with similar operational capacities.
Utsläppsminskningar och energianvändning är områden som har blivit väl diskuterade under den senaste tiden. För att kunna uppnå målet som många tillverkningsföretag har, att sänka sina utsläpp, så skulle utvecklingen av ett verktyg för att mäta koldioxidutsläppen vara till stor hjälp. Ett sådant verktyg kan vara nyckeln till att identifiera och undersöka områden med förbättringsmöjligheter inom hela produktionen. Det här examensarbetet försöker skapa ett verktyg för att beräkna koldioxidutsläppen i en tillverkningsmiljö, detta genom att göra en fallstudie på ett företag som tillverkar cylindriska stift i Järna. I det här examensarbetet bryts processerna ner del för del i ett mål att kunna hitta alla delar inom produktionen som bidrar till utsläppen. Ett sådant verktyg, använt för att kvantifiera utsläppen från en produkt, skulle kräva ett samarbete från företagets ledning samt deras underleverantörer för att få all viktig information som krävs för beräkningarna. Fortsättningsvis, för att kunna erhålla en översiktlig, ekologisk undersökning av en produkt, gjordes en undersökning av alla primära samt sekundära aktiviteter inom fabriken. Utöver att tillverka ett verktyg för att mäta koldioxidutsläpp, en viktig del inom detta projekt var att undersöka hur liknande företag med liknande miljöer har delat med sig av sina utsläpp och metoderna för hur dem uppnått dem. Verktyget använder den tidigare nämnda data för att kunna beräkna koldioxidutsläppen av några produkter tillverkade på fabriken för att eventuellt kunna identifiera metoder för att förbättra företagets ekologiska hållbarhet. Vikten av att ha ett bra verktyg för att beräkna sina utsläpp, och att ett sådant verktyg ska fungera för liknande beräkningar med liknande miljöer är avgörande för en mer hållbar framtid inom tillverkningsindustrin.

Amgen's Operations division is responsible for the production, release and distribution of commercial and clinical products. Due to industry consolidation, impending competition and revenue impacts, Amgen is facing the need to rapidly improve the Operations division and align different manufacturing sites. In order to achieve these goals, the Operations Improvement group is leading an initiative to bring about a lean transformation of Amgen's operations.This thesis analyzes the initial operational excellence efforts underway within Amgen Operations. The analysis includes an overview of the process by which the continuous improvement methodology and strategy were constructed, the creation of a training curriculum and the initial implementation of the continuous improvement methodology at specific manufacturing sites. In addition, the thesis explores the environment in which this program operates and the cultural and business drivers that support and detract from the efforts.The following conclusions were developed as a result of the analysis of the lean transformation efforts at Amgen. First, company and industry specific nomenclature is essential to make lean principles contextually relevant for the biopharmaceutical industry. Additionally, relevant metrics are needed to facilitate multi-site alignment and drive the desired behavior. Finally, continuous improvement efforts can effectively leverage a science-based culture by applying it to a new business context.

Analysis of flexible manufacturing cells (FMCs) shows their requirement for flexible, correct, reliable, safe and distributed control. A comparison of the state of the art in software engineering for parallel systems, and an examination of safety related systems, reveal a need for formal and rigorous techniques at all stages in the software life cycle. However, parallel software, safety related software and formal techniques are complex. It is better to avoid faults rather than eliminate or tolerate them, and although less flexible, avoidance is often simpler to implement. There is a need for a tool which overcomes many of these complexities, and this thesis discusses and defines such a tool in the form of a methodology. The novelty of the work is in the combination of the core goals to manage these issues, and how the strategies guide the user to a solution which will not deadlock and which is comprehensible. Place-transition Petri nets are an ideal representation for designing and modelling the interaction of concurrent (and distributed) processes. Occam is a high level real time parallel language designed to execute on one or a network of transputers. Transputers are processing, memory and communication building blocks, and, together with occam, are shown to be suitable for controlling and communicating the control as the DCS in FMCs. The methodology developed in this thesis adopts the mathematically based tools of Petri nets, occam and transputers, and, by exploiting their structural similarities, incorporates them in a steps and tasks to improve the development of correct, reliable and hence safe occam code. The four steps: identify concurrent and sequential operations, produce Petri net graphs for all controllers, combine controller Petri net graphs and translate Petri net graphs into occam; are structured around three core goals: Petri net/occam equivalence, comprehensibility and pro-activity; which are manifest in four strategies: output-work-backwards, concurrent and sequential actions, structuralise and modularise, and deadlock avoidance. The methodology assists in all stages of the software development life cycle, and is applicable to small DCSs such as an FMC. The methodology begins by assisting in the creation of DCS requirements from the manufacturing requirements of the FMC, and guides the user to the production of dependable occam code. Petri nets allow the requirements to be specified as they are created, and the methodology's imposed restrictions enable the final Petri net design to be translated directly into occam. Thus the mathematics behind the formal tools is hidden from the user, which should be attractive to industry. The methodology is successfully applied to the example FMC, and occam code to simulate the FMC is produced. Due to the novelty of the research, many suggestions for further work are given.

The work for this thesis was performed at Honeywell in the Automation and Control Solutions (ACS) division. The project focuses on ACS's manufacturing strategy regarding its global supply chain design, primarily discussing the manufacturing growth opportunities available in emerging regions. Honeywell ACS's current methodology for the development of a long-term manufacturing strategy is based on growth and total cost reduction objectives. In order to comprehend the total cost of the manufacturing strategy, considerations such as inventory, logistics and duties, outsourcing and material sourcing are evaluated. The project also considers a factory's geographical location and ACS's year-by-year implementation plan. An outcome of this Honeywell project and the basis of this thesis is the development of a general supply chain design and optimization methodology that utilizes three analytical tools (Country Selection Framework, Total Cost Model and Implementation Plan Process) that are capable of validating the supply chain design of any company. The analytical tools can be used to verify key strategic supply chain decisions or to create a baseline manufacturing strategy. The following results can be determined using this supply chain design methodology: Determine an appropriate operating region for current or future business needs; Evaluate the feasibility of factory relocation projects by considering all relevant costs; Evaluate the cost implications of the supply chain structure by considering logistics, inventory and material sourcing costs; Understand the impact of outsourcing on the manufacturing strategy; Recommend a year-by-year implementation plan in the case of multiple projects and limited capital resources.
