Study On The Applications Of Optimal Design Of General Layout For Industrial Enterprise Based On The Petri Net

The General Layout design for industrial enterprises is the progress of coverting the abstract production system to the operational & reality production system, and is the important part of implementing the production system. The General design, on which the others design based, is essential in engineering design. The reasonable programme of layout can lower capital costs, save investment, increase the production efficiency in the later producing, and maximize the overall efficiency of enterprises, so as to enhance the enterprises' competitiveness in the market.At present, the major methods of General design are partial qualitaive analysis rather than quantitative analysis. Design mainly relys on rich experience in the past. The programme of layout lack convincing in a certain extent. The article introduces Petri net in the General Layout Design, establishes the model of production system by the Petri net, which have powerful functions to simulate the objective world. Then, the close code of production between the various workshops are drawn, through the model analysis. The article puts forwards the general design based on the close code of production and the integrated close code. The paper makes the following aspects of work:Firstly, the paper describes the current methods of The General Layout Design for industrial enterprises, and analysis advantages and disadvantages of these methods. The paper overview the development process of Petri net and its application and introduce the basic concepts & theories about Petri net, the work drift-nets based on Petri net and related theories.Secondly, it theoretically studies the method of establishing the model of industrial enterprises production system and analyzesing the model by the basic Petri net according to the current design process & methods and production facilities system of industrial enterprises. The paper systematically offers the method and operational procedures of The General Layout Design and Optimization Systematically based on Petri net. Finally, the paper takes a general layout of a forklift factory as example, and come to a better design layout programme. As a result, the reliability and feasibility of the method can be proved.The paper makes meaningful exploration in the general design of industrial enterprises by theoretical research & engineering caculation, and draws the method & operational procedures of general layout design and optimization systematically based on Petri net, which can guide the industrial enterprises general design. During the development of our country's industry, this research has theoretical and practical significance.
