Since technology risk exists widely in the weapon equipment development project, it is better to describe the budget as fuzzy number. However, technology risk is neglected in the current earned value management (EVM), which often builds the baseline of the budget with crisp numbers. Therefore, we introduce technology risk to EVM, and propose an improved method of fuzzy earned value management (FEVM) for the weapon development project. The proposed FEVM fully considers technology risk during the project development, and applies the technology readiness level (TRL) concept to estimate the budgeted cost. By utilizing fuzzy theory, the fuzzy assessment standard based on degree of possibility for the cost and schedule of high risk project is given, as well as fuzzy prediction of the estimate completion cost (ECC) and estimate completion time (ECT). The proposed method is illustrated through an example. The proposed method extends the applicability of the EV techniques for the weapon equipment development project with technology risks, and can better help decision-makers to control risks and bring cost and schedule back to the baseline.
