Schedule-cost Joint Management of Thermal Power Construction Project Based on Improved Earned Value Method

摘要

The risk of schedule and cost is the core part in the thermal power construction projects, while the traditional earned value method often ignores the existence of the risk in the schedule and cost analysis. This paper presents an improved earned value analysis method considering risk factors. In the method, the schedule and cost performance indicator is fuzzed based on trapezoidal fuzzy number, then introduces risk level coefficient to construct fuzzy earned value method considering risk factors based on the cut, and realize the integration of risk management and schedule cost analysis. Finally, one thermal power project is taken as an example to testify the practicability and validity of the improved model.
