Research On Merger And Balance Of Road Machinery Assembly Line Based On Plant Simulation

Generally, excess capacity can be solved through the methods of merger and reorganization, transfering capacity, eliminating production line and optimizing the enterprise. Under the influence of the international economic situation becoming bad and China’s economic growth speed appearing slow, the demand of Chinese engineering machinery is lowering and many engineering machinery enterprises appear the problem of excess production capacity. It becomes particularly feasible to reduce the internal cost and solve the problem of excess production capacity through a merger between the assembly lines.This topic is just from T road machinery enterprise actual production conditions, and through the combination between the road roller assembly line and the grader assembly line, the purpose of reducing consumption and improving business efficiency can be achieved. The research firstly analyzes the T road machinery company existing assembly lines, to obtain assembly data from the road roller assembly line and the grader assembly line; analyze the assembly data and verify T road machinery company existing overcapacity from data.According to the orders in 2015 and estimation to the future of road machinery market, reset the company production targets. According to the goal of enterprise, solve the problem of the assembly lines’ merger. Under the enterprise constraints, allocate assembly work stations for road roller and grader to obtain a merger plan between the road roller assembly line and the grader assembly line. Finish a system modeling of the merger plan between the road roller assembly line and the grader assembly line through the computer simulation technology and obtain the simulation model. Start simulation of the merger assembly model, and analyze the assembly line balancing according to the simulation result. Calculate the assembly line balancing rate and smoothness index of the road roller assembly line and the grader assembly line, to get comprehensive evaluation of combined assembly line. Put forward optimization strategies to the bottleneck workstation and the "unfair" of merge assembly line load. Summarize the optimization conclusion and modify the simulation model. Start simulation of the merger assembly model again after the optimization to get the simulation results as well as the final conclusion.Research on merger and balance of road machinery assembly line based on Plant Simulation eventually achieved good results to assembly line balance optimization. Assembly line balancing rate and smoothness index improved greatly.
