This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we consider demand management decisions for an assemble-to-order production system in which both the availability of intermediate material and assembly capacity are limited. For each incoming order, the manufacturer must decide whether to accept it and what due date to quote for an accepted order. The actual assembly dates are still subject to change after these decisions, and a production schedule must be maintained to guarantee that the quoted due dates are met. Therefore, the decisions on accepting orders and quoting due dates must be made with incomplete knowledge of the actual resources used to fulfill the orders. To address these factors, we model this situation and develop a novel revenue management approach using bid prices. An extensive numerical study demonstrates the good performance of the proposed approach in comparison with benchmark algorithms and an ex-post optimal solution applied over a wide range of different supply and demand scenarios. Our results suggest that the consideration of assembly capacity constraints is more vital than the consideration of intermediate material constraints in our test cases.

Download or read book Order Acceptance and Scheduling at a Make to order System Using Revenue Management written by Anshu Jalora and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Make-to-order (MTO) systems have been traditionally popular in manufacturing industries that either seek to provide greater variety to their customers or make products that are unique to their customers. More recently, with shrinking product life cycles, there is an increasing interest in operating as MTO systems. With the tremendous success of revenue management techniques in the service industries over the last three decades, there is a growing interest in applying these techniques in MTO manufacturing industries. In the present work, we consider three problems that apply revenue management (RM) to on-date delivery MTO systems. In the first problem, we assume that all orders completed in advance of their due-dates are stored at third party warehouses and apply RM in computing efficient order acceptance and scheduling policies. We develop an optimal solution scheme, and based on the insights gained on the structural properties of the optimal solution, we develope a stochastic approximation scheme for finding efficient solutions. Through computational studies on simulated problems, we illustrate the potential of RM in improving net profits over popular practices. In our second problem, we extend the RM model to consider presence of a certain amount of first party warehousing capacity for storing the orders completed in advance of their due-dates. We study the conditions under which it is desirable to consider the holding cost aspects in the RM model. In our third problem, we develop a scheme for determining an efficient capacity of the first party warehouse that is used for storing the orders completed in advance of their due-dates at an on-date delivery MTO system. This scheme captures the completed orders storage demand resulting from a RM based order acceptance and scheduling policy. We illustrate that when booking horizon is large, considerable amount of savings in the holding costs can be made with an efficiently sized first party warehouse.

This book was released on 2011-08-08 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unified, systematic approach to applying mixed integer programming solutions to integrated scheduling in customer-driven supply chains Supply chain management is a rapidly developing field, and the recent improvements in modeling, preprocessing, solution algorithms, and mixed integer programming (MIP) software have made it possible to solve large-scale MIP models of scheduling problems, especially integrated scheduling in supply chains. Featuring a unified and systematic presentation, Scheduling in Supply Chains Using Mixed Integer Programming provides state-of-the-art MIP modeling and solutions approaches, equipping readers with the knowledge and tools to model and solve real-world supply chain scheduling problems in make-to-order manufacturing. Drawing upon the author's own research, the book explores MIP approaches and examples-which are modeled on actual supply chain scheduling problems in high-tech industries-in three comprehensive sections: Short-Term Scheduling in Supply Chains presents various MIP models and provides heuristic algorithms for scheduling flexible flow shops and surface mount technology lines, balancing and scheduling of Flexible Assembly Lines, and loading and scheduling of Flexible Assembly Systems Medium-Term Scheduling in Supply Chains outlines MIP models and MIP-based heuristic algorithms for supplier selection and order allocation, customer order acceptance and due date setting, material supply scheduling, and medium-term scheduling and rescheduling of customer orders in a make-to-order discrete manufacturing environment Coordinated Scheduling in Supply Chains explores coordinated scheduling of manufacturing and supply of parts as well as the assembly of products in supply chains with a single producer and single or multiple suppliers; MIP models for a single- or multiple-objective decision making are also provided Two main decision-making approaches are discussed and compared throughout. The integrated (simultaneous) approach, in which all required decisions are made simultaneously using complex, monolithic MIP models; and the hierarchical (sequential) approach, in which the required decisions are made successively using hierarchies of simpler and smaller-sized MIP models. Throughout the book, the author provides insight on the presented modeling tools using AMPL® modeling language and CPLEX solver. Scheduling in Supply Chains Using Mixed Integer Programming is a comprehensive resource for practitioners and researchers working in supply chain planning, scheduling, and management. The book is also appropriate for graduate- and PhD-level courses on supply chains for students majoring in management science, industrial engineering, operations research, applied mathematics, and computer science.
Download or read book Supply Chain Planning written by Hans-Otto Günther and published by Springer Science & Business Media. This book was released on 2009-03-05 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, supply chain planning has emerged as one of the most challenging problems in the industry. As a consequence, the planning focus is shifting from the management of plant-speci?c operations to a holistic view of the various logistics and productionstages, that is an approach in which suppliers, productionplants and customers are considered as constituents of an integrated network. A major dr- ing force behind this development lies in the globalization of the world economy, which has facilitated the co-operation between different partners working together in world-wide logistics networks. Hence, considerable cost savings can be gained from optimizing the structure and the operations of complex supply networks li- ing plants, suppliers, distribution centres and customers. Consequently, to improve the performance of the entire logistic chain, more sophisticated planning systems and more effective decision support are needed. Clearly, successful applications of supply chain management have driven the development of advanced planning systems (APS), which are concerned with s- porting decision-making activities at the strategic, tactical and operational decision level. These software packages basically rely on the application of quantitative methods, which are used to model the underlying complex decision problems c- sidering the limited availability of resources and the need to react on time to customer orders. The core module at the mid-term level of APS comprises op- ational supply chain planning. In many industries, productionstages are assigned to differentplantsand distribution centreshave been established at geographicallyd- persed locations.

Available in PDF, EPUB and Kindle. Book excerpt: Online scheduling is recognized as the crucial decision-making process of production control at a phase of “being in production" according to the released shop floor schedule. Online scheduling can be also considered as one of key enablers to realize prompt capable-to-promise as well as available-to-promise to customers along with reducing production lead times under recent globalized competitive markets. Online Scheduling in Manufacturing introduces new approaches to online scheduling based on a concept of cumulative delay. The cumulative delay is regarded as consolidated information of uncertainties under a dynamic environment in manufacturing and can be collected constantly without much effort at any points in time during a schedule execution. In this approach, the cumulative delay of the schedule has the important role of a criterion for making a decision whether or not a schedule revision is carried out. The cumulative delay approach to trigger schedule revisions has the following capabilities for the practical decision-making: 1. To reduce frequent schedule revisions which do not necessarily improve a current situation with much expense for its operation; 2. To avoid overreacting to disturbances dependent on strongly an individual shop floor circumstance; and 3. To simplify the monitoring process of a schedule status. Online Scheduling in Manufacturing will be of interest to both practitioners and researchers who work in planning and scheduling in manufacturing. Readers will find the importance of when-to-revise policies during a schedule execution and their influences on scheduling results.

Download or read book Quality Improvement Inventory Management Lead Time Reduction and Production Scheduling in High mix Manufacturing Environments written by Sean Michael Daigle and published by . This book was released on 2017 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is a compilation of the analysis and recommendations gathered from two industry projects conducted at Applied Materials Varian Division in Gloucester, MA and at the MIT Lincoln Laboratory in Lexington, MA. This thesis addresses the improvement of a quality metric used at Applied Materials through the means of material shortage reduction and lead time reduction of system sub-assemblies. Manufacturing quality was found to be impacted by material shortages across the facility and capacity constraints in an area of the facility that manufactures equipment subassemblies. Implementing a new inventory policy would result in an expected 74% to 80% reduction in material shortage occurrences. The capacity increase recommended in this thesis would reduce average lead time for sub-assemblies from about 5-6 days to under 2 days. At the MIT Lincoln Lab, this thesis addresses a possible approach to improving the accuracy of production scheduling and delivery date quotes through the use of job shop scheduling software and historical data analysis. The recommended fabrication request delivery date prediction process involves using a scheduling software to find the optimal delivery date for a job, and then adding a Shop Capacity Buffer time that is calculated using historical data on schedule delays. Schedule delays can be caused by a variety of random events that occur in machine shops, such as machine failures or operators falling ill. By selecting a Shop Capacity Buffer of 90%, a 90% on-time completion rate should be observed. This new method would achieve improved results from the 75% on-time completion rate at present. The final recommendation is a policy change that aims to characterize sources of delay and accurately compensate for the delay using the Shop Capacity Buffer in the delivery date quote process..
Download or read book Manufacturing Scheduling Systems written by Jose M. Framinan and published by Springer Science & Business Media. This book was released on 2014-02-19 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is devoted to the problem of manufacturing scheduling, which is the efficient allocation of jobs (orders) over machines (resources) in a manufacturing facility. It offers a comprehensive and integrated perspective on the different aspects required to design and implement systems to efficiently and effectively support manufacturing scheduling decisions. Obtaining economic and reliable schedules constitutes the core of excellence in customer service and efficiency in manufacturing operations. Therefore, scheduling forms an area of vital importance for competition in manufacturing companies. However, only a fraction of scheduling research has been translated into practice, due to several reasons. First, the inherent complexity of scheduling has led to an excessively fragmented field in which different sub problems and issues are treated in an independent manner as goals themselves, therefore lacking a unifying view of the scheduling problem. Furthermore, mathematical brilliance and elegance has sometimes taken preference over practical, general purpose, hands-on approaches when dealing with these problems. Moreover, the paucity of research on implementation issues in scheduling has restricted translation of valuable research insights into industry. "Manufacturing Scheduling Systems: An Integrated View on Models, Methods and Tools" presents the different elements constituting a scheduling system, along with an analysis the manufacturing context in which the scheduling system is to be developed. Examples and case studies from real implementations of scheduling systems are presented in order to drive the presentation of the theoretical insights. The book is intended for an ample readership including industrial engineering/operations post-graduate students and researchers, business managers, and readers seeking an introduction to the field.
