ABSTRACT
ABSTRACT: According to the Characteristics of industrial construction projects, this paper establishes the system model and economic model of the investment recovery period, analyses the random factors that influence the investment recovery period of industrial construction projects, confirms the probability distribution of random factors statistical data with the hypothetical test method of statistics, and then forms the simulation model of payback period combined with system simulation theory. By using the matlab language, it achieves the simulation model, then analyses the precision of simulation results according to central limit theorem. Finally, combined with practical examples, further demonstrates the model’s feasibility, the results show that the simulation predicting model can be used as the important basis for the industrial construction projects’ investment decision making.
