According to the production and other information of the engine testing line,make full use of the module provided by Plant Simulation software to build the simulation model; run the model of engine testing line in the case of both ideal working condition and the condition that actual random factors exist,then analyses the production,burden rate of the equipment and the bottleneck issue,etc. of the line. Based on this,optimize the engine testing line,and the result of the simulation shows that the production...
