Risk source identification of complex equipment development project

Complex equipment development project characters of high risk and many research units result in risk transmission in the development process. To solve the risk source identification problem, a risk source identification method was proposed based on association rule (AR) and decision making trial and evaluation laboratory (DEMATEL). The association rules between risk type and risk factors were solved firstly, and then the interaction of the risk sources was obtained, both with data mining method. Finally, each risk source's relevant parameters were obtained through DEMATEL. Besides, a case was analyzed and the risk sources identification was completed by AR-DEMATLE method on a stage of the data stored in the database of a research unit. The identification result shows that the risk sources corresponding to various risk types and the risk sources leading to risk transmission easily.
