Research On Production Efficiency Simulation And Optimization Strategy Of Machinery Manufacturing Enterprise

With the promotion of "Made in China 2025" strategy,accelerating the development of manufacturing industry and establishing a high-level and intelligent manufacturing industry has become the direction of China’s future manufacturing industry.At present,the development of China’s domestic machinery manufacturing enterprises as a whole presents a trend of horizontal expansion,but the depth of vertical development in the system is still not enough,and the production efficiency of enterprises does not reach the standard in the case of losing the advantage of labor cost.The purpose of this paper is to conduct a detailed analysis of the internal production links of China’s machinery manufacturing enterprises,study the key factors affecting the production efficiency of each link,and establish a simulation model of the production efficiency of domestic machinery manufacturing enterprises.The paper selects H enterprise,which is a certain representative of China’s machinery manufacturing enterprises,as an example,and carries out simulation analysis on its production efficiency.Finally,it provides countermeasures for domestic machinery manufacturing enterprises including H enterprise to improve production efficiency for reference.In this paper,by analyzing the main factors affecting the production efficiency of the current machinery manufacturing enterprises in China,the method combining the fishbone diagram and the analytic hierarchy method is used for factor analysis and weight calculation,and the application of system dynamics to simulate the internal system model.Through simulation analysis,the reasons influencing the production efficiency of the machinery manufacturing enterprises are studied.The specific research contents of this paper mainly include the following parts:In this paper,the development of machinery manufacturing enterprises and the domestic and foreign research results on the production efficiency of enterprises were studied through the literature method,and the final integrated research literature was used as the background support of this study.In this paper,the definition of manufacturing and machinery manufacturing enterprises and the theory of production efficiency are summarized.Second machinery manufacturing enterprises in our country are analyzed using the fishbone diagram analysis in such aspects as manpower,equipment,raw materials various influence factors of production efficiency,and analytic hierarchy process is used to analyse the main factors influencing the statistics,and then calculate the weights in the manpower,equipment,raw materials mainly in three aspects: the influencing factors of machinery manufacturing enterprise production efficiency.Finally,on the basis of the combination of fishbone diagram and analytic hierarchy method,the system dynamics method is used to systematically study the three aspects of manpower,equipment and raw materials in machinery manufacturing enterprises,and the system dynamics subsystem model considering the corresponding influencing factors is established.Paper with H enterprise as an example,studied the three subsystems of different endogenous variables influence on mechanical manufacturing enterprise production efficiency,and establish the corresponding subsystem according to the results of the simulation of a variety of optimization strategy,through the comparison of simulation results,different strategies for machinery manufacturing enterprises,including H enterprise,put forward the corresponding countermeasures to the improvement in production efficiency.
