Product development two-factor risk model and simulation based on DSM

  • To solve the risk measurement of product development with iterations, a modeling method to evaluate the risk of schedule and cost in product development was constructed, and a simulation algorithm was given to analysis the risk of product development process. The model was constructed by two stages, rework probability matrix and rework impact matrix were firstly established based on design structure matrix(DSM), which described the relationships between schedule, cost and iteration. The evaluation model was then set up according to schedule and cost uncertainty, iteration uncertainty and the structure matrix. At the same time, the idea to decrease schedule and cost risk of product development was introduced through reducing iterations. Finally, a case was presented to illustrate the model, which indicated the model can measure product development-s schedule and cost risk, and also decrease schedule and cost risk by adopting product development sequence optimization based on DSM. This is useful to measure and control product development risk.
