This book was released on 2007 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: We consider multistage, stochastic production systems using pull control for production authorization in discrete parts manufacturing. These systems have been widely implemented in recent years and constitute a significant aspect of lean manufacturing. Extensive research has appeared on the optimal sizing of buffer inventory levels in such systems. However the issue of control points, i.e. where in the multistage sequence to locate the output buffers, has not been addressed for pull systems. Allowable container/batch sizes, optimal inventory levels, and ability of systems to automatically adjust to stochastic demand depend on the location of these control points. We begin by examining a serial production system producing a single part type. Two models are examined in this regard. In the first, container size is independent of the control section, while in the second, container sizes are section dependent. Additionally, a nesting policy is introduced which introduces the additional constraint that the container size in a section is related to the container size in any other section by a power of two. Necessary and sufficient conditions are derived for ensuring that a single, end-of-line accumulation point is optimal. When this is not the case, an algorithm is provided to determine the optimal control points. Effects of factors such as value added structure, fixed location cost, setup and material handling cost, kanban collection time, and material transportation time on the control structure are investigated. Results are extended to determine the optimal container size when lead time at a stage is a concave function of container size. The study is then extended to a multi-product case. Queuing aspects are introduced to account for the interaction between the different part types. The queuing model used is a modification of the Decomposition/Recomposition model described in Shantikumar and Buzacott (1981). The models in the chapter do not assume a serial structure any longer. Additionally, general interarrival and service time distributions are considered. The effect of number of products, demand arrival distribution, value added structure, and number of stages on the control structure and system cost is investigated. Finally, a simulation model is developed in Chapter 5 to verify and validate the mathematical models described in Chapters 3 and 4.

Book Synopsis Production Control Systems by : Yacob Khojasteh
Download or read book Production Control Systems written by Yacob Khojasteh and published by Springer. This book was released on 2015-08-21 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selecting a suitable production control policy is a challenging task for managers because the superiority of one control over the other is controversial. This book analyzes pull production systems and provides a guideline to choose and implement a proper control policy in production processes. By employing a proper control policy the maximum possible throughput of the production system can be achieved with the minimum work-in-process inventory. Kanban, CONWIP, and base-stock as wellknown pull control policies are analyzed and analytical comparisons among them in multistage serial and assembly production processes are presented. Illustrated by carefully chosen examples and supported by analytical solutions, discussions provided in the book clarify the complexity of the comparisons that show there is no general superiority among the control systems. Th e book explains which structural parameters decide the superiority of one control scheme to the others, and how they are related. Given a confi guration of parameters, such as processing times and number of cards employed in the system, the superior control policy can be selected.
Book Synopsis Stochastic Modeling of Manufacturing Systems by : George Liberopoulos
Download or read book Stochastic Modeling of Manufacturing Systems written by George Liberopoulos and published by Springer Science & Business Media. This book was released on 2005-12-12 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing systems rarely perform exactly as expected and predicted. Unexpected events, such as order changes, equipment failures and product defects, affect the performance of the system and complicate decision-making. This volume is devoted to the development of analytical methods aiming at responding to variability in a way that limits its corrupting effects on system performance. The book includes fifteen novel chapters that mostly focus on the development and analysis of performance evaluation models of manufacturing systems using decomposition-based methods, Markovian and queuing analysis, simulation, and inventory control approaches. They are organized into four distinct sections to reflect their shared viewpoints: factory design, unreliable production lines, queuing network models, production planning and assembly.
Book Synopsis Multi-Stage Production Planning and Inventory Control by : Sven Axsäter
Download or read book Multi-Stage Production Planning and Inventory Control written by Sven Axsäter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Production Management by : Yacob Khojasteh
Download or read book Production Management written by Yacob Khojasteh and published by CRC Press. This book was released on 2017-11-07 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inventory control is an essential task in production management. An effective inventory control can significantly reduce the holding cost and hence, total production cost. Selecting and implementing a suitable production control system plays an important role in inventory reduction and performance improvement of a production system. Since the introduction of Toyota’s just-in-time philosophy, pull control systems have been adopted by numerous companies worldwide, both in the manufacturing and service sectors. This book provides some recent developments in production management and presents modeling and analysis tools for pull production control systems. It contributes by combining theoretical findings and case study analysis results with a practical and contemporary view on how to effectively manage and control production systems. Each chapter in this book focuses on a specific topic in production control systems, allowing readers to identify the chapters that relate to their interests. More specifically, the book is presented in three sections. The first section focuses on the design and implementation aspects of the pull production control systems, as well as performance evaluation approaches for pull systems. The second section presents a recent and comprehensive literature review. Three different case studies on implementation of pull production control systems are presented in the last section. This book can be used as an essential source for students and scholars who need to specifically study the pull control systems. Since the superiority of these systems is controversial, the book can also provide an interesting and informative read for practitioners, managers, and employees who need to deepen their knowledge on pull production management systems.

Book Synopsis Handbook of Ripple Effects in the Supply Chain by : Dmitry Ivanov
Download or read book Handbook of Ripple Effects in the Supply Chain written by Dmitry Ivanov and published by Springer. This book was released on 2019-04-17 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an introduction to the ripple effect in the supply chain for a broad audience comprising recent developments. The chapters of this handbook are written by leading experts in supply chain risk management and resilience. For the first time, the chapters present in their synergy a multiple-faceted view of the ripple effect in supply chains, while considering organization, optimization, and informatics perspectives. Ripple effect describes the impact of a disruption propagation on supply chain performance, structural designs and operational parameters. The ripple effect manifests when the impact of a disruption cannot be localized and cascades along the supply chain. The resulting structural dynamics can lead to capacity and demand fulfilment downscaling and negatively influence the firm’s financial and operational performance. The book delineates major features of the ripple effect and methodologies to mitigate the adverse impact of supply chain disruption propagation and to recover in case of severe disruptions. The book provides fresh insights for supply chain management and engineering regarding the following questions: - In what circumstance does one failure cause other failures? - Which structures of the supply chain are especially susceptible to the ripple effect? - What are the typical ripple effect scenarios and what are the most efficient ways to respond them? Distinctive Features: • It considers ripple effect in the supply chain from an multi-disciplinary perspective• It offers an introduction to ripple effect mitigation and recovery policies in the framework of disruption risk management in supply chains for a broad audience• It integrates management and engineering perspectives on disruption risk management in the supply chain• It presents innovative optimization and simulation models for real-life management problems• It considers examples from both industrial and service supply chains• It reveals decision-making recommendations for tackling disruption risks in the supply chain in proactive and reactive domains.
Book Synopsis Engineering Production Control Strategies by : Christoph Karrer
Download or read book Engineering Production Control Strategies written by Christoph Karrer and published by Springer Science & Business Media. This book was released on 2012-02-25 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying and customizing suitable control strategies is a challenging task, especially when production systems have to cope with variable demands, forecast error, and unstable processes. The focus of this book lies on helping companies with complex and discrete production systems to tailor a production control strategy to their needs. Thereby, the mutual merits of “push” and “pull” systems are taken into account, leading to hybrid strategies. Consequently, the book addresses practitioners who are interested in looking behind the scenes and into the physics of production control. A real-life case study demonstrates the practical applicability of the presented framework.

This book was released on 2010-03-10 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Postponement strategy is one of the major supply chain management (SCM) pr- tices that has a discernible impact on rms’ competitive advantage and organi- tional performance. Postponement is a mass customization strategy that captures the advantages of both mass production and mass customization. Recent research studies have identi ed four common postponement strategies, namely pull, logistics, form and price postponement. The former three postponement strategies are linked to production and manufacturing, while the last one is a pure pricing strategy. They aim at balancing the costs and bene ts of mass production and mass customization. Practical examples of postponement can be found in the high-tech industry, food industry and other industries that require high differentiation. However, empirical studies have found that postponement may not be an evident SCM practice compared to the other practices. In addition, postponement has both positive and negative impacts on a supply chain. The advantages include following the JIT principles, reducing end-product inventory, making forecasting easier and pooling risk. The high cost of designing and manufacturing generic components is the main drawback of postponement. Thus, the evaluation of postponement strategy is an important research issue and there have been many qualitative and quantitative models for analyzing postponement under different scenarios.

This book was released on 2012-12-06 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing industries are devoted to producing high-quality products in the most economical and timely manner. Quality, economics, and time not only indicate the customer-satisfaction level, but also measure the manufacturing per formance of a company. Today's manufacturing environments are becoming more and more complex, flexible, and information-intensive. Companies invest into the information technologies such as computers, communication networks, sensors, actuators, and other equipment that give them an abundance of information about their materials and resources. In the face of global competition, a manufacturing company's survival is becoming more dependent on how best this influx of in formation is utilized. Consequently, there evolves a great need for sophisticated tools of performance analysis that use this information to help decision makers in choosing the right course of action. These tools will have the capability of data analysis, modeling, computer simulation, and optimization for use in designing products and processes. International competition also has had its impact on manufacturing education and the government's support of it in the US. We see more courses offered in this area in industrial engineering and manufacturing systems engineering departments, operations research programs, and business schools. In fact, we see an increasing number of manufacturing systems engineering departments and manufacturing research centers in universities not only in the US but also in Europe, Japan, and many developing countries.
