This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: O presente trabalho analisa o Problema da Programação de Lotes Econômicos (ELSP) que, freqüentemente, se apresenta em indústrias com processos produtivos em linha (onde a produção segue uma seqüência especificada de operações). Tal linha deve manufaturar diferentes produtos, só sendo possível fabricar um produto por vez. Além disso, para o caso estudado, outra característica importante é que os tempos e custos de setup dependem da seqüência de fabricação escolhida. O objetivo do problema é determinar uma seqüência de produção que permita obter conjuntamente os menores custos de setup e de manter estoques, satisfazendo a demanda do mercado sem atrasos. É factível, na teoria, encontrar matematicamente uma solução ótima para o problema, mas sua obtenção se torna impraticável pelas numerosíssimas possibilidades e muitas variáveis a considerar. Por tal motivo, recorre-se ao uso de métodos heurísticos. Neste trabalho analisam-se os dados fornecidos por uma empresa de refrigerantes, que possui um processo em linha, e se estabelecem as seqüências e os volumes de produção para cada produto, obtendo custos próximos do ótimo. O método que se propõe não só é útil para o caso específico, senão também pode ser adaptado a indústrias que guardem características semelhantes.

Download or read book Multi-Stage Simultaneous Lot-Sizing and Scheduling written by Florian Seeanner and published by Springer Science & Business Media. This book was released on 2013-05-13 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to a varying product demand (changing product mix) and different production speeds, bottlenecks may shift between the stages. In that case, a simultaneous lot-sizing and scheduling of these stages is recommendable. Hence, an improved version of the General Lot-Sizing and Scheduling Problem for Multiple production Stages (GLSPMS) was developed. Moreover, several reformulation techniques were applied to this model to solve it exactly. Besides, a new meta-heuristic which combines the principles of Variable Neighborhood Decomposition Search (VNDS) and Exchange was implemented to find good solutions, even for a real-world problem case. Finally, further model extensions, e.g., for scarce setup resources, were proposed.

Download or read book The Lot Scheduling Problem in the Hierarchy of Decision Models written by Robert Sheldon and published by . This book was released on 1986 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The economic lot scheduling problem (ELSP) surfaces from competition among products for a scarce resource, usually machine time. When scheduling production of batches in this environment, two issues must be resolved: the size of batches and the start times for production of each batch. Standard approaches to the ELSP focus on scheduling multiple products on a single machine. This thesis addresses three important issues that put the scheduling problem in the context of its physical setting and range of parameters: idle time, the zero switch rule, and stochastic input to a bottleneck machine. In most scheduling heuristics, the reason for idle time is to balance cyclic production patterns. Idle time is also optimal in solutions to problems with high setup costs. We show that the condition for inducing idle time, given zero setup costs, is when one product has dominant holding costs and the remaining products have low machine utilization. A common policy in scheduling is to start production only after the inventory reaches zero. This policy is called the zero switch rule (ZSR) and is regarded as a good scheduling policy. We show that the condition when ZSR is not optimal is when the ZSR solution yields lumpy production patterns for a product with dominant holding costs.

Download or read book Lot-Sizing and Scheduling for Flexible Flow Lines written by Daniel Quadt and published by Springer Science & Business Media. This book was released on 2012-09-14 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book considers the lot-sizing and scheduling problem for flexible flow line production facilities. Flexible flow lines are flow lines with parallel machines on some or all production stages. They can be found in a vast number of industries. A three-phased solution approach is presented that solves the integrated lot-sizing and scheduling problem in a hierarchical manner. The approach is able to handle several important features relevant in industrial practice, such as back-orders and setup carry-over. The developed solution procedures solve practically sized problems in a relatively short amount of time. One of the procedures is based on a novel mixed integer programming (MIP) model, which employs integer variables instead of binary variables. This makes it possible to find (near-)optimal solutions using standard algorithms such as CPLEX. Another procedure uses two nested Genetic Algorithms. An application of the framework in the semiconductor industry is given.

This book was released on 2018-02-09 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Stochastic Economic Lot Scheduling Problem: Heavy Traffic Analysis of Dynamic Cyclic Policies We analyze two variants of the scheduling problem. In the setup cost problem, a cost is incurred when the machine switches production from one product to another; in the setup time problem, a random setup time is incurred when the server switches product. We restrict ourselves to the class of dynamic cyclic policies, where each product is serviced once per cycle and the order of production does not change. Thus, the server has three scheduling options at each point in time: Produce a unit of the product that is currently set up, change over to the next product in the cycle (and initiate service in the setup cost problem), or remain idle. Each product has its own costs per unit time for holding and backordering a unit in inventory. The objective in the setup time problem is to minimize the long run expected average inventory costs (that is, holding and backorder costs); the objective in the setup cost problem is to minimize the average inventory and setup costs.
