Scheduling of various manufacturing systems using metaheuristic approaches

Abstract

Manufacturing system is significant by the ever varying expectation and mushrooming challenges in the global market. The requirement of customers are manifold which press a serious challenge to manufacturing system that is forced to adopt some changes to foster efficiency and production process. It is necessary to produce their products at very low expense without compromising quality avoiding any delay in executing the products at appropriate time. They should be open to adopt any additional changes in design with respect to demand without high investment. Traditional Manufacturing systems i.e. job shop and flow lines floundered to fulfill the demands which have brought flexible manufacturing system (FMS) as a solution for the raising challenges in the Competitive market. Today manufacturing system s efficiency and its impact have gained more attention. The perfect scheduling of a job is instrumental in determining the rate of success for the shop. Scheduling as a decision tool, determines the usage of resources, adaptation of time and expense level to execute the activities. The calculation of initial time and end time controls the sequence to be processed over the jobs to meet the equirements or objectives. Tremendous effort in computation is the only option for acing and fulfilling the problems of scheduling. Unfortunately, we are coining the terms as and#8215;NP-hard or and#8215;NP-complete problems in scheduling which facilitate the implementation of heuristic method for large sized problems. This complete nature prevailing in scheduling instigates the selection of smarter techniques or tools to arrive at suitable solutions. Conventional optimization techniques couldn t provide solutions to the diverse and complex optimization problems in the manufacturing system. newline
