摘要：Recently, it’s universal phenomenon that large engineering projects like environmental protection projects are over budget and late. It puts plan management workers into trouble and wastes social resource largely. As a management way in modern project management, the minimum non-zero total float in CPM network plays an important role in time management and cost management. Therefore, this paper expounds time parameters and relationships between float time and the length of path firstly. And then this paper puts forward three kinds of calculation methods, which are calculating the total float of all the non-critical process, calculating the minimum non-zero float time of node and calculation method on the basis of minimum non-zero total float process distribution theorem. The second calculation method of minimum non-zero total float is the biggest innovation of this paper. This method reduces amount of calculation and improves the computational efficiency greatly and proves to be practical.
