A hybrid algorithm optimization approach for machine loading problem in flexible manufacturing system
The production planning problem of flexible manufacturing system (FMS) concerns with decisions that have to be made before an FMS begins to produce parts according to a given production plan during an upcoming planning horizon. The main aspect of production planning deals with machine loading problem in which selection of a subset of jobs to be manufactured and assignment of their operations to...
متن کاملRole of batch size in scheduling optimization of flexible manufacturing system using genetic algorithm
Flexible manufacturing system (FMS) readily addresses the dynamic needs of the customers in terms of variety and quality. At present, there is a need to produce a wide range of quality products in limited time span. On-time delivery of customers’ orders is critical in make-to-order (MTO) manufacturing systems. The completion time of the orders depends on several factors including arrival rate, ...
متن کاملConcurrent Tolerance Design with Alternative Manufacturing Processes
Traditional practice to tolerance design has been based on a sequential approach to design and manufacturing considerations. An integrated approach involving simultaneous selection of design and manufacturing tolerances was introduced in the last decade. Choice of manufacturing processes (or machines) from amongst the alternatives, frequently encountered in different stages of realization of in...
متن کاملMultiobjective Genetic Algorithm for Scheduling Problems in Manufacturing Systems
Scheduling is an important tool for a manufacturing system, where it can have a major impact on the productivity of a production process. In manufacturing systems, the purpose of scheduling is to minimize the production time and costs, by assigning a production facility when to make, with which staff, and on which equipment. Production scheduling aims to maximize the efficiency of the operation...
متن کاملOptimization of profit and customer satisfaction in combinatorial production and purchase model by genetic algorithm
Optimization of inventory costs is the most important goal in industries. But in many models, the constraints are considered simple and relaxed. Some actual constraints are to consider the combinatorial production and purchase models in multi-products environment. The purpose of this article is to improve the efficiency of inventory management and find the economic order quantity and economic p...
