Due to customized products, the traditional mode of production is unable to provide low-cost, short delivery time of products and bear the enormous pressure of market competition. Therefore, Mass Customization production is developing rapidly to become the manufacturing industry mainstream model on the Information Age. Meanwhile, production scheduling takes an important part in Mass Customization production, for the quality of scheduling relates to the cost, the delivery time, even to the success or failure of mass customization production. In this paper, the simulation model of a factory’s production is built by eM - Plant. According to the operational flow of the factory and the feature of the simulation system, the flow of simulation is designed based on eM - Plant, including the parametric simulation module, such as the station module, transit module, and statistics module. By running the original scheduling simulation, system records relevant data and calculates the original scheduling of working hours consumption. Furthermore, with the Genetic Algorithm of eM - Plant simulation software, the optimization model is also built to analyze the
