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 Variants of Evolutionary Algorithms for Real-World Applications written by Raymond Chiong and published by Springer Science & Business Media. This book was released on 2011-11-13 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary Algorithms (EAs) are population-based, stochastic search algorithms that mimic natural evolution. Due to their ability to find excellent solutions for conventionally hard and dynamic problems within acceptable time, EAs have attracted interest from many researchers and practitioners in recent years. This book “Variants of Evolutionary Algorithms for Real-World Applications” aims to promote the practitioner’s view on EAs by providing a comprehensive discussion of how EAs can be adapted to the requirements of various applications in the real-world domains. It comprises 14 chapters, including an introductory chapter re-visiting the fundamental question of what an EA is and other chapters addressing a range of real-world problems such as production process planning, inventory system and supply chain network optimisation, task-based jobs assignment, planning for CNC-based work piece construction, mechanical/ship design tasks that involve runtime-intense simulations, data mining for the prediction of soil properties, automated tissue classification for MRI images, and database query optimisation, among others. These chapters demonstrate how different types of problems can be successfully solved using variants of EAs and how the solution approaches are constructed, in a way that can be understood and reproduced with little prior knowledge on optimisation.

This book was released on 2016 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Production planning is a crucial activity for companies to satisfy customers demand while minimizing cost. The objective of this research is to optimize the production planning and scheduling decisions of companies in petrochemical industry field. A Mixed-Integer Linear Programming (MILP) model is developed for the capacitated lot sizing and scheduling problem with sequence dependent setup costs; that considers the chain of multiple suppliers, affiliates, warehouses and customers. Different grades can be produced by each affiliate, and a changeover cost occurs when changing the production from one grade to another. The model integrates scheduling and lot-sizing decisions with the logistics functions of transportation and warehousing. In particular, it provides answers to questions regarding the amount of each raw material to be purchased from each supplier, sequence of production plans, inventory levels, and warehouse selection to satisfy orders. Petrochemical companies usually own several joint-ventures and centrally prepare the affiliates' production plans for the upcoming periods; their current planning procedures do not consider the overall costs in their supply-chain. The developed model will integrate their raw material costs, production and sequencing costs, inventory costs and transportation costs from the supplier side across the supply-chain to the customer side. The problem under study is considered an NP-Hard problem due to its complexity and size; therefore, a three stage heuristic was developed which provided good quality solutions with an acceptable computational time. The first stage of the heuristic works on reducing the complexity of the model by removing the sequencing decisions; where the resulting model decides only the size of lots for each affiliate. In the second and third stages, an iterative process is done to reduce the total setup and total holding costs while restoring the sequencing decisions. The heuristic was applied on different problem instances of different sizes and the reported results were within a range of 0.09% - 2.0% away from optimality. The development of the Mixed-Integer Linear Programming and the Three Stage Heuristic is the main contribution of this research."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents scheduling with a medium- and short-term focus, which makes it possible to capitalize on fleeting market opportunities while simultaneously working to reconcile economic and environmental priorities. It introduces a new mixed-integer approach to hierarchical discrete-time and continuous-time scheduling, combining aspects of production and recycling, forward and reverse logistics as well as emissions trading for multi-stage supply chain networks. Problem-specific variants of relax-and-fix heuristics and genetic algorithms are also proposed. Given its scope, the book provides a range of practical tools and new perspectives for researchers and professionals in the field of supply chain management.

Download or read book Production Planning by Mixed Integer Programming written by Yves Pochet and published by Springer Science & Business Media. This book was released on 2006-04-19 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a comprehensive modeling, reformulation and optimization approach for solving production planning and supply chain planning problems, covering topics from a basic introduction to planning systems, mixed integer programming (MIP) models and algorithms through the advanced description of mathematical results in polyhedral combinatorics required to solve these problems. Based on twenty years worth of research in which the authors have played a significant role, the book addresses real life industrial production planning problems (involving complex production structures with multiple production stages) using MIP modeling and reformulation approach. The book provides an introduction to MIP modeling and to planning systems, a unique collection of reformulation results, and an easy to use problem-solving library. This approach is demonstrated through a series of real life case studies, exercises and detailed illustrations. Review by Jakub Marecek (Computer Journal) The emphasis put on mixed integer rounding and mixing sets, heuristics in-built in general purpose integer programming solvers, as well as on decompositions and heuristics using integer programming should be praised... There is no doubt that this volume offers the present best introduction to integer programming formulations of lotsizing problems, encountered in production planning. (2007)

Download or read book Capacitated Lot Sizing Problems in Process Industries written by Ravi Ramya and published by Springer. This book was released on 2019-01-04 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the Capacitated Lot Sizing Problem (CLSP) in process industries. In almost all process industries, there are situations where products have short/long setup times, and the setup of the product and its subsequent production are carried over, across consecutive periods. The setup of a product is carried over across more than one successive period in the case of products having long setup times. A product having short setup has its setup time less than the capacity of the period in which it is setup. The setup is immediately followed by its production of the product and it may also be carried over, across successive time period(s). Many process industries require production of a product to occur immediately after its setup (without the presence of idle time between the setup and production of the product), and they also require the product to be continuously produced without any interruption. This book considers a single-machine, single-level and multiple-item CLSP problem. This book introduces the Capacitated Lot Sizing Problem with Production Carryover and Setup Crossover across periods (CLSP-PCSC). Mathematical models are proposed which are all encompassing that they can handle continuous manufacturing (as in process industries), and also situations where the setup costs and holding costs are product dependent and time independent/time dependent, with possible backorders, and with other appropriate adaptations. Comprehensive heuristics are proposed based on these mathematical models to solve the CLSP-PCSC. The performance of the proposed models and heuristics are evaluated using problem instances of various sizes. This book also covers mathematical models developed for the Capacitated Lot Sizing Problem with Production Carryover and Setup Crossover across periods, and with Sequence-Dependent Setup Times and Setup Costs (CLSP-SD-PCSC). These models allow the presence of backorders and also address real-life situations present in process industries such as production of a product starting immediately after its setup and its uninterrupted production carryover across periods, along with the presence of short/long setup times. Heuristics proposed for the CLSP-PCSC can be extended to address the CLSP problem with sequence dependent setup costs and setup times. All the models and heuristics proposed in this book address some real-life considerations present in process industries.
