Optimization of Scheduling in Power Generation Engineering Projects Based on Critical Chain
-
Abstract
Engineering enterprises in China mainly develop project schedule based on the Critical Path Method (CPM), and control the schedule based on the Earned Value Concept (EVC). This Method is effective without resource limit, but the old project management mode cannot meet the market and the needs of the development of the enterprise any more. This paper mainly research time management of power generation engineering projects based on Critical Chain with case study. On single project management, considering the effect of human behavior, the trisection shear method is adopted to estimate the construction period and set up the buffer. The safety time of estimating with the traditional method is summed up to a buffer, which increases the probability of finish on time without reducing the total duration. On multi-project management, this paper uses the fuzzy comprehensive evaluation based on analytic hierarchy process to deal with priority levels. Then it allocates constraint resources of capacity as a whole, which optimizes all the project schedules in the same enterprise.
