THE MULTI-AGENT MODELLING OF PRODUCTIONLOGISTICS SYSTEM AND THE SHOP DYNAMICSCHEDULING OPTIMIZATION IN DISCRETEMANUFACTURING ENTERPRISES

摘要

At present, the production logistics is becoming an importantrncomponent for the manufacturing industry to upgrade the corerncompetitiveness. The scheduling of the enterprise'srnproduction logistics system is proved to be a NP completernproblem. The multi-agent physical model of the enterprise'srnproduction logistics is set up, basing on the multi-agentrntechnique. This model can be divided into two sub-models ofrnthe shop operation lay and the controlling lay. It puts forwardrna dynamic scheduling model of the production logistics, andrndescribes the basic trusses of the production logisticsrnscheduling agents, especially introduces the mathematicalrnmodel of the process agent based on the dynamic schedulingrnalgorithms. The process agent model can judge from thernproduction capacity that whether it is capable to accept thernprocess tasks. Under the premiss that the production capacityrnpermits, takes the process cost, transport cost, process time,rntransport time into integrated consideration to choose thernoptimal process route, and discusses the correspondingrnscheduling regulation and strategy according to the differentrnscheduling tasks and performance requests. The example ofrnthe normal scheduling and the abnormal scheduling of thernenterprise shop's production logistics proved the validity andrnthe feasibility of the simulated model. The establishment ofrnthe model provides a new method for the simulation andrnscheduling optimization of the complex production logisticsrnsystem.
