This paper proposes a Fuzzy-Safety-Buffer approach for measuring the project buffer size in critical chain project scheduling. The method focuses on the combination of the requirements of the project manages and the customers. Firstly using the trapezoidal fuzzy function, agreement index presents the project managers' requirement. Then the safety buffer concept derived from the safety stock concept...
Based on the superposition theory of partial differential equation (PDE), a new method is introduced here to solve complicated problems of flow field. In this method, a problem of flow field with complex boundary conditions and source items is divided into several problems of flow fields with simple boundary conditions and source items, and then the solution of a complicated problem of flow field...
