Critical Chain Project risk control with Management strengths

The application of critical chain breaks through the bottleneck of project management, and enhances the project risk management. However, the calculation of the buffer is a hot issue in Critical Chain Project Management (CCPM), and the current calculation methods lack management theory. In this paper,the management strength fuzzy variable is introduced creatively, and it provides a bridge between management theory and mathematics, analyses the success factors of the CCPM. The model which combines management and mathematics is set up. The model is a new method which can confirm the project buffer, and the case study proved that it has a strong theoretical reliability.
