Many Varieties Of Small Batch Mode Connector Production Scheduling Research

This paper studied the variety of small batch mode connector production scheduling plan.For many varieties of small batch mode connector production some problems and difficulties,the DBR method in the analysis using the theory of constraints,based on the theory of constraints connector production scheduling plan model,and solved.Model considering the connection of assembly constraints exist in production,process,delivery time constraints,such as constraint conditions,using the method of DBR,on production of the "bottleneck" for priority scheduling,according to the t heory of constraints in the push and pull the idea of combining production practice respectively before and after the bottleneck pull production and push the production,and behind the assembly link set delivery buffer order to improve the production effic iency of the whole system and yield rate.The main research content of this paper includes:(1)this paper expounds the main production plan based on theory of constraints(TOC)model.Article 9 the basic principles and production control method of DBR and detailed explains the steps.Focused on the environment in many varieties and small batch production,how to use DBR production planning and control to identify bottlenecks,setting buffer,scheduling bottleneck resources and setting production batch and mass transport.(2)the production scheduling problem of mathematical symbols and combining with the parameter representation are described.Focus on the processing environment,processing constraints,and the optimization goal has carried on the detailed instructions.In Outlines the many varieties of small batch production mode characteristics on the basis of production scheduling,the scheduling problem of multiple varieties of small batch production mode for mathematical modeling,and to make the mathematical model is more close to actual situation,to a certain degree of complement of mathematical model,for the establishment of intelligent scheduling prototype system provides sufficient preparation.(3)the model of a problem to solve.DBR method of combining the theory of constraints on the machine in the production of bottleneck resources.On the front of the semi-finished products production design became a pull production;Designed to push on the subsequent assembly production production;And in th e final assembly with the ship buffer.A series of design to ensure more varieties of small batch mode of connector of production scheduling orders into production efficiency and yield rate on time.Finally through to the many varieties of small batch mode connector production scheduling problem in the research and modeling analysis of the established system model is applied to actual cases.The model can improve the case of orders timely delivery,reasonable control inventory,reduce the production cost,in the process of help to promote the competitiveness of the company’s products.Theoretical model for technology is applied to the actual application of production scheduling research may provide the technical foundation.
