Book excerpt: Excerpt from The Stochastic Economic Lot Scheduling Problem: Heavy Traffic Analysis of Dynamic Cyclic Policies We consider two queueing control problems that are stochastic versions of the economic lot scheduling problem: a single server processes N customer classes, and completed units enter a finished goods inventory that services exogenous customer demand. Unsatisfied demand is backordered, and each class has its own general service time distribution, renewal demand process, and holding and backordering cost rates. In the first problem, a setup cost is incurred when the server switches class, and the objective is to minimize the long run expected average costs of holding and backordering inventory and incurring setups. The setup cost is replaced by a setup time in the second problem, where the objective is to minimize average holding and backordering costs. In both problems we restrict ourselves to a class of dynamic cyclic policies, where idle periods and lot sizes are state-dependent, but the N classes must be served in a fixed sequence. Under standard heavy traffic conditions, these scheduling problems are approximated by diffusion control problems. The approximating setup cost problem is solved exactly, and the optimal dynamic lot sizing policy is found in closed form. Structural results and an algorithmic procedure are derived for the setup time problem. A computational study is undertaken to compare the proposed policy and several straw policies to the numerically computed optimal policy.

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.

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.
