Study And Application On The Theory Of Shop Scheduling And Evaluation For Manufacturing Enterprise

Manufacturing is one of the pillar cornerstone industries in the 21st century and manufacturing play an important role in economic increase.It has brought higher demand for enterprises management and production in the 21st century's global market.Production scheduling is the foundation of manufacturing system,and its optimization is the core technique of the advanced manufacture and the modern management.Scheduling has become one of key links of raising the resources utilization ratio and the operating performance for the enterprise.Based on the theoretical study of production scheduling,as well as the analysis of manufacturing enterprises and its shop production scheduling characteristics,the special enterprise's shop production scheduling model is proposed in this dissertation,and some key technologies also are studied.(1) This dissertation studies manufacturing shop production scheduling model, and expatiates the relation of yield plan and production scheduling,and lucubrates shop production scheduling characteristics,and proposes the enterprise's shop production scheduling model which is based on optimization algorithm.By emphasizing the process control based on fact and data,the model also introduces its implementation.(2) Based on flow-scheduling process,the structure of the optoelectronic product shop flow-scheduling system is established.Based on genetic algorithm,the flow-scheduling is researched in detail,and the optimization of its several essential parameters in flow scheduling is analyzed especially.This dissertation studies the multi-objective flow scheduling problems and its algorithm model is established based on genetic algorithm,and discusses the parallel machine scheduling problems, and gives an application example.(3) Based on the analysis of job-scheduling process,the analytic emphasis is laid on the job scheduling system based on genetic algorithm.The optimization of its several essential parameters in job scheduling is analyzed.This dissertation also gives the algorithm model for numerical control machining enterprise,and helps enterprise to meet production demands more effectively.(4) This dissertation constructs the prototype system of shop production scheduling and management combined with the actual valve machining company. This dissertation introduces its implementation,and the results of application demonstrate the feasibility and advance of study contents in dissertation.(5) This dissertation studies manufacturing shop scheduling evaluation index system,and studies fuzzy analytical hierarchical processes and its implementation. After analyzing the characteristic of fuzzy analytical hierarchical processes,this dissertation gives manufacturing shop scheduling evaluation prototype system,and gives the analysis examples to ilhistrate its.Based on shop scheduling system,according the shop practical needs,the enterprise resource can be reasonably distributed and scheduled,the enterprise can save the operating cost and improve on its adaptability for the market changes and enhance the shop operating efficiency.The given shop production scheduling and management model and its key technologies are in favor of promoting the shop scheduling management theory and implementation for valve enterprise,which also has great significance for continual improving the production management level.
