Mix-model Production Scheduling Modeling And Algorithm Design For PN Company CT Workshop

Merging with the manufacturing technology and information technology,automation technology,modern management techniques and systems engineering approach in recent years,people have proposed Flexible Manufacturing System.Computer Integrated Manufacturing System,Agile Manufacturing System,Lean Production System,Virtual Manufacturing System,ERP,Bionic Manufacturing System and many other advanced manufacturing mode,although the principles and technology to achieve these advanced manufacturing mode there is a big difference,but they are reasonable optimization and configuration of internal and external resources,to shorten the manufacturing cycle,reduce production costs to resolve many of the common problems facing enterprises generally.Production Scheduling is an effective means of resource allocation and optimization,a good production scheduling production capacity operating balanced arrangement to each machine,and reasonable arrangements for the processing of each job order,meet the system constraints,optimization of relevant performance indicators.Therefore,the production scheduling naturally become the core content and important part of various advanced manufacturing mode of common concern.In this paper,based on a review of the history of the development of the workshop production scheduling problem and its scheduling algorithm,First,based on first analysis of the domestic and international workshop scheduling research status and development trend of the shop scheduling,job-shop scheduling problem classification definition,summary shop scheduling problem of the definition and process of the workshop planning and control.PN company CT workshop production research,analysis and the CT workshop production scheduling problems,find the root cause,summary CT shop scheduling requesting improvements.CT workshop the mixed production scheduling principle,specify the goal of the production scheduling to determine the CT workshop mixed production operating standards for these operating standard the CT production model to integrate,and then build a the CT workshop mixed production scheduling model.The comparison of various search algorithms to determine the use of the CT workshop of the genetic algorithm for PN company mixed production scheduling algorithm design,and by the Matlab simulation,the scheduling model and simulation results analysis and evaluation.This shop scheduling model and algorithm design,a significant improvement in efficiency and accuracy of the PN company CT workshop scheduling.This paper is Mixed model assembly line environment scheduling conclusion help future generations based multi-constrained multi-objective Mixed model assembly line scheduling problems on further study can also be extended to the Multi-objective,multi-constraint,difference work piece hybrid flow shop scheduling problem(HFSS).
