The logic of Manufacturing Resource Planning (MRP II) is usually implemented in production planning and control systems and therefore has a major impact on the performance of many real production systems. Much of what practitioners complain about, i.e. long lead times, high work-in-process, and large inventories, is due to the deficiencies of the MRP II concept. Thus, researchers are eager to find better models and methods to improve or to replace the current status. This book contains new ideas on master production scheduling, material requirements planning, lot sizing, sequencing and scheduling, and production control. Management scientists, industrial engineers, operations researchers, and computer scientists have contributed to present the state-of-the-art.
This paper treats a two-echelon inventory system. The higher echelon is a single location reffered to as the depot, which places orders for supply of a single com modity. The lower echelon consists of several points, called the retailers, which are supplied by shipments from the depot, and at which random demands for the item occur. Stocks are reviewed and decisions are made periodically. Orders and/or shipments may each require a fixed lead time before reaching their respective desti nations. Section II gives a short literature review of distribution research. Section III introduces the multi-echelon distribution system together with the underlying as sumptions and gives a description of how this problem can be viewed as a Markovian Decision Process. Section IV discusses the concept of cost modifications in a distribution context. Section V presents the test-examples together with their optimal solutions and also gives the characteristic properties of these optimal solutions. These properties then will be used in section VI to give adapted ver sions of various heuristics which were used in assembly experiments previously and which will be tested against the test-examples.
The Advanced Research Institute (A.R. 1.) on "the efficiency of Manufacturing Systems" was held under the auspices of the NATO Special Programm~ Panel on Systems Science as a part of the NATO Science Committee's continuous effort to promote the advancement of science through international co-operation. Advanced Research Institutes are organised for the purpose of bringing together experts in a particular field of interest to identify and make known the present state of knowledge in that area and, through informed debate, to make recommendations for directions for future research that would benefit the community at large. To this end two kinds of contribution were obtained by invitation. There were those papers which were about the current state of work in the area of manufacturing systems and its organisation; in addition three theme papers were presented to provide a stimulus to the discussion in terms of ways of thinking, both about the area and about the kind of research needed.
This unique book provides a guide to the selection of appropriate production and manufacturing methods for postgraduate and professional manufacturing engineers. It starts by helping the reader to identify the required objectives of industrial management for their particular situation. Having identified the objectives an analytical assessment of the available production and management methods is made. The analytical system presents an objective method of production selection. For example, this practical book will help the reader to decide whether or not a local Just-in-Time process is needed or a full chain JIT method is needed. Alternatively the problem may be deciding between set-up time reduction or changeover time reduction. Should TQM be ceded to PCIs? This book covers nearly all methods of production and manufacturing and will prove the most comprehensive guide to choosing and using these methods. Only book of its kind available Widest coverage of methods available Analytical approach to decision making
This book covers the design and improvement of single and multistage production systems. Following the standard production planning and scheduling decision hierarchy, it describes the inputs and outputs at each level of the decision hierarchy and one or more decision approaches. The assumptions leading to each approach are included along with the details of the model and the corresponding solution. Modern system concepts and the engineering methods for creating lean production systems are included.
Consider the possibility of a manufacturing method that can do all this: reduce lead time increase product diversity produce higher-quality products allow more competitive pricing ensure customer satisfaction reach dominance in the global marketplace Those are all part of the upside potential for the Matrix Manufacturing Method. Its promising premise: apply beneficial technology to all stages of the manufacturing process, leading to increased efficiency. Actually, the Matrix Manufacturing Method is far more than a mere promise; it's already become standard and successful practice at many companies. Details of the Matrix Manufacturing Method now make their first-ever appearance in Restructuring the Manufacturing Process: Applying the Matrix Method, describing this important new philosophy of manufacturing management-and practical ways to bring its concepts into reality. A pioneer of the Matrix Manufacturing Method, Halevi presents comprehensive and convincing details behind its rationale and practice. The method's foundation: incorporate engineering stages (technology) during production management stages, allowing qualified professionals to make crucial decisions at execution time, through the use of accurate and flexible engineering data. As the book's case histories demonstrate, companies that have taken those measures now benefit from a "new degree of freedom" in the manufacturing cycle-and its myriad advantages. Numerous theories may have been proposed to create technology-driven manufacturing processes: what makes the Matrix Manufacturing Theory most valuable is its improvements of all disciplines, aspects, and activities related to product production. Gain that all-inclusive competitive edge with Restructuring the Manufacturing Process: Applying the Matrix Method.
This book is a guide to modern production planning methods based on new scientific achievements and various practical planning rules of thumb. Several numerical examples illustrate most of the calculation methods, while the text includes a set of programs for calculating production schedules and an example of a cloud-based enterprise resource planning (ERP) system. Despite the relatively large number of books dedicated to this topic, Advanced Planning and Scheduling is the first book of its kind to feature such a wide range of information in a single work, a fact that inspired the author to write this book and publish an English translation. This work consists of two parts, with the first part addressing the design of reference and mathematical models, bottleneck models and multi-criteria models and presenting various sample models. It describes demand-forecasting methods and also includes considerations for aggregating forecasts. Lastly, it provides reference information on methods for data stocking and sorting. The second part of the book analyzes various stock planning models and the rules of safety stock calculation, while also considering the stock traffic dynamics in supply chains. Various batch computation methods are described in detail, while production planning is considered on several levels, including supply planning for customers, master planning, and production scheduling. This book can be used as a reference and manual for current planning methods. It is aimed at production planning department managers, company information system specialists, as well as scientists and PhD students conducting research in production planning. It will also be a valuable resource for students at universities of applied sciences.
