This book was released on 1998 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing global competition has led the manufacturing enterprises to adopt FMS to respond to producing a variety of products in low quantities, low costs, high quality and short lead times. The benefits associated with FMS can only be realised if the systems are planned and designed properly. In this research work, two KB computer models are developed for the planning and design of an FMS. An expert system shell AM is used for the development and implementation of the methodology. A Knowledge Based Flexible Manufacturing System Planning (KBFMSP) Model is developed to address the planning issues of an FMS such as demand information, part types information, machine information, MHS information and LAN information. The planning stage is primarily used for finding a potential demand for the system, characteristics and process plan of the part types to be manufactured, machines (Turning and Milling centres) selection, MHS (AGV-robot based and conveyor-robot based) and selecting a computer communication network architecture. Production rules are used in the planning methodology which, by using a forward chaining strategy, arrive at a decision. After successful execution of the rules, the control of the programme then moves to the design stage. At the design stage, a Knowledge Based Flexible Manufacturing System Design (KBFMSD) Model is developed to address the detailed design issues of the FMS such as required number of machines, a suitable MHS, machines and MHS layout and financial assessment. A hybrid (knowledge base plus analytical) methodology is incorporated in the KBFMSD Model to help calculate the key design factors and to assist in arriving at a completed FMS design. The viability of the FMS design is checked by using various financial assessment criteria such as Break Even Analysis, Net Present Value (NPV), Internal Rate of Return (IRR) and the Pay Back Period methods. Finally, the planning and design models are tested, verified and validated by using industrial and published case studies information. The results indicate that the KB methodology developed for the integrated planning and design of FMS is a viable technique and produces realistic and consistent results.

Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, the production of mechanical components to be assembled in final products produced in high volumes (e.g. cars, mopeds, industrial vehicles, etc.) has undergone deep changes due to the overall modifications in the way companies compete. Companies must consider competitive factors such as short lead times, tight product tolerances, frequent market changes and cost reduction. Anyway, companies often have to define production objectives as trade-offs among these critical factors since it can be difficult to improve all of them. Even if system flexibility is often considered a fundamental requirement for firms, it is not always a desirable characteristic of a system because it requires relevant investment cost which can jeopardize the profitability of the firm. Dedicated systems are not able to adapt to changes of the product characteristics while flexible systems offer more flexibility than what is needed, thus increasing investment and operative costs. Production contexts characterized by mid to high demand volume of well identified families of products in continuous evolution do not require the highest level of flexibility; therefore, manufacturing system flexibility must be rationalized and it is necessary to find out the best trade-off between productivity and flexibility by designing manufacturing systems endowed with the right level of flexibility required by the production problem. This new class of production systems can be named Focused Flexibility Manufacturing Systems-FFMSs. The flexibility degree in FFMSs is related to their ability to cope with volume, mix and technological changes, and it must take into account both present and future changes. The required level of system flexibility impacts on the architecture of the system and the explicit design of flexibility often leads to hybrid systems, i.e. automated integrated systems in which parts can be processed by both general purpose and dedicated machines. This is a key issue of FFMSs and results from the matching of flexibility and productivity that respectively characterize FMSs and Dedicated Manufacturing Systems (DMSs). The market share of the EU in the machine tool sector is 44%; the introduction of focused flexibility would be particularly important for machine tool builders whose competitive advantage is based on the ability of customizing their systems on the basis of needs of their customers. In fact, even if current production contexts frequently present situations which would fit well with the FFMS approach, tradition and know-how of machine tool builders play a crucial role. Firms often agree with the focused flexibility vision, nevertheless they decide not to pay the risk and efforts related to the design of this new system architecture. This is due also to the lack of well-structured design approaches which can help machine tool builders to configure innovative systems. Therefore, the FFMS topic is studied through the book chapters following a shared mission: "To define methodologies and tools to design production systems with a minimum level of flexibility needed to face, during their lifecycle, the product and process evolution both in the technological and demand aspects. The goal is to find out the optimal trade-off between flexibility and productivity". The book framework follows the architecture which has been developed to address the FFMS Design problem. This architecture is both broad and detailed, since it pays attention to all the relevant levels in a firm hierarchy which are involved in the system design. Moreover, the architecture is innovative because it models both the point of view of the machine tool builder and the point of view of the system user. The architecture starts analyzing Manufacturing Strategy issues and generating the possible demand scenario to be faced. Technological aspects play a key role while solving process plan problems for the products in the part family. Strategic and technological data becomes input when a machine tool builder performs system configuration. The resulting system configurations are possible solutions that a system user considers when planning its system capacity. All the steps of the architecture are deeply studied, developing methods and tools to address each subproblem. Particular attention is paid to the methodologies adopted to face the different subproblems: mathematical programming, stochastic programming, simulation techniques and inverse kinematics have been used. The whole architecture provides a general approach to implement the right degree of flexibility and it allows to study how different aspects and decisions taken in a firm impact on each other. The work presented in the book is innovative because it gives links among different research fields, such as Manufacturing Strategy, Process Plan, System Design, Capacity Planning and Performance Evaluation; moreover, it helps to formalize and rationalize a critical area such as manufacturing system flexibility. The addressed problem is relevant at an academic level but, also, at an industrial level. A great deal of industrial sectors need to address the problem of designing systems with the right degree of flexibility; for instance, automotive, white goods, electrical and electronic goods industries, etc. Attention to industrial issues is confirmed by empirical studies and real case analyses which are presented within the book chapters.

This book was released on 2013-03-09 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flexible manufacturing systems are complex production systems with considerable high investment costs. This book intends to show the reader how the design of such a system can be optimized. Thereby it addresses the academic world in management science and industrial engineering as well as system planners in industry. First the design problems are analysed in detail and a planning concept is presented. Afterwards possible tools for the design process are described, as there are: mathematical programming, queueing networks, computer simulation, perturbation analysis, petri nets, group technology, and knowledge based systems. The major part of the book, however, concerns the description of existing optimization models based on mathematical programming. Each model is explained and discussed in detail and for new models, developed by the author, numerical examples are given. Finally some distinct guidelines are presented which help the system planners to select the appropriate model for their planning problems.

This book was released on 2008-11-14 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook was developed to ?ll the need for an accessible but comprehensive presentation of the analytical approaches for modeling and analyzing models of manufacturing and production systems. It is an out growth of the efforts within the Industrial and Systems Engineering Department at Texas A&M to develop and teach an analytically based undergraduate course on probabilisticmodeling of m- ufacturingtype systems. The level of this textbook is directed at undergraduate and masters students in engineering and mathematical sciences. The only prerequisite for students using this textbook is a previous course covering calculus-based pr- abilityand statistics. The underlyingmethodology is queueing theory, and we shall develop the basic concepts in queueing theory in suf?cient detail that the reader need not have previously covered it. Queueing theory is a well-established dis- plinedatingback to theearly 1900’sworkof A. K. Erlang, a Danish mathematician, on telephone traf?c congestion. Although there are many textbooks on queueing theory, these texts are generally oriented to the methodological development of the ?eld and exact results and not to the practical application of using approximations in realistic modeling situations. The application of queueing theory to manufact- ing type systems started with the approximation based work of Ward Whitt in the 1980’s. His paper on QNA (a queueing network analyzer) in 1983 is the base from which most applied modeling efforts have evolved. There are several textbooks with titles similar to this book.

This book was released on 1999-01-29 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: One critical barrier leading to successful implementation of flexible manufacturing and related automated systems is the ever-increasing complexity of their modeling, analysis, simulation, and control. Research and development over the last three decades has provided new theory and graphical tools based on Petri nets and related concepts for the design of such systems. The purpose of this book is to introduce a set of Petri-net-based tools and methods to address a variety of problems associated with the design and implementation of flexible manufacturing systems (FMSs), with several implementation examples.There are three ways this book will directly benefit readers. First, the book will allow engineers and managers who are responsible for the design and implementation of modern manufacturing systems to evaluate Petri nets for applications in their work. Second, it will provide sufficient breadth and depth to allow development of Petri-net-based industrial applications. Third, it will allow the basic Petri net material to be taught to industrial practitioners, students, and academic researchers much more efficiently. This will foster further research and applications of Petri nets in aiding the successful implementation of advanced manufacturing systems.

This book was released on 2005-12-05 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since manufacturing has acquired industrial relevance, the problem of adequately sizing manufacturing plants has always been discussed and has represented a di?cult problem for the enterprises, which prepare strategic plans to competitively operate in the market. Manufact- ing capacity is quite expensive and its exploitation and planning must be carefully designed in order to avoid large wastes, or to preserve the survival of enterprises in the market. Indeed a good choice of ma- facturing capacity can result in improved performance in terms of cost, innovativeness, ?exibility, quality and service delivery. Unfortunately the capacity planning problem is not easy to solve because of the lack of clarity in the decisional process, the large number of variables involved, the high correlation among variables and the high level of uncertainty that inevitably a?ects decisions. The aim of this book is to provide a framework and speci?c methods and tools for the selection and con?guration of capacity of Advanced Manufacturing Systems (AMS). In particular this book de?nes an - chitecture where the multidisciplinary aspects of the designofAMSare properly organized and addressed. The tool will support the decisi- maker in the de?nition of the con?guration of the system which is best suited for the particular competitive context where the ?rm operates or wants tooperate. Thisbookisofinterest for academic researchers in the ?eldofind- trial engineering and particularly indicated in the areas of operations and manufacturing strategy.

This book was released on 1988 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research is concerned with certain production planning problems associated with flexible manufacturing systems (FMS) with high tool variety. In this environment of FMS, the tool requirements at workstations exceed the respective tool magazine capacities. During an extensive survey of related literature, it appeared that the problems associated with this type of FMS have been overlooked by the FMS research community. The operational problems of FMS are discussed with special reference to the constraints imposed by tooling. The characteristics of the selected FMS type are clearly defined. This discussion is supplemented with a detailed description of a real FMS which resembles the operations of the selected type of FMS. Having identified certain drawbacks of some existing simulation software, the development of a comprehensive FMS simulator which uses a novel hybrid modelling technique is discussed. The use of a graphical post-processor which can be used to enhance the system logic of the FMS is also described number of parameters associated with the tool management system are identified and the methods are described to evaluate these parameters. The importance of evaluating these parameters in design and operation of an FMS is stressed. The development of a tool post-processor which can assist in identifying the scale of the tooling problem and in evaluating tool management parameters is presented. A variety of tool availability strategies which reduce the tool exchange rates are suggested and evaluated. Finally, the part selection (for immediate processing) problem is solved using a novel technique which takes the advantage of the availability of real time data in FMS.
