The Research Of The Industrial Enterprise Logistics Based On System Dynamics

Industrial enterprise logistics it studies to be present logistics weak link of research field, strengthen and have very important meaning to research of the logistics of industrial enterprise.Systematic theory of dynamics and modeling method is the foundation of this text, the logistics system of industrial enterprise isthe research object of this text. Use systematic dynamics carry on to industrial enterprise logistics research is a new try.Industrial enterprise logistics system makes up by the subsystem of production logistics , logistics of supplying, sell logistics , retrieve and discard logistics . Every subsystem interact and exert an influence to the whole logistics system of industrial enterprise. There are many complicated factors that influence the industrial enterprise logistics system and its subsystem, with the aid of traditional method and means we can't descripte its complicated relation. Establish systematic dynamics emulation model to descript these complicated relations are not merely ocular, and can descript the objective actual conditions even more.The logistics system dynamics model of industrial enterprise set upin this text includes four subsystem$they are production logistics, logistics of supplying, sell logistics, discard logistics. During set up the model,have done abundant analysis to enterprise history business data,and regard business plan as basic value of model. Have considered various kinds of subjective and objective factors (f the logistics system among the models Some influence of these factor are overall, some are localized The range that they influencejhe process and the possible result of function are discussed separately in the articleAll these factor are included among the flowing chart, and then labeled the causality of them with streamline of system dynamics emulation languageIn the article, a series of systematic dynamics equationsto these causality have been set up by statistic and experiential method.Through initial analysisof model emulation result, expound interreaction of all influence factor further When the emulation result of the model is not satisfied, it need the result to be controled. The process of control on emulation result, is a process of adjusting influence factor value constantly to model itself,but to a concrete industrial enterprise, it is a processthat logistics system perfects constantly. From control process and control result of the model set up in this article, it have realized to keep enterprise's logistics in the comparatively satisfactory level on the whole.The understanding of the logistics of industrial enterprise is a continual process, and the industry enterprise logistics system oneself is also a research for continuously perfect process, therefore,it needs further study on the industry enterprise logistics system.
