The project management cycle is the core of project management, while temporal analysis is the basis of project scheduling in this cycle. The Program Evaluation and Review Technique (PERT) used in traditional temporal analysis implies the following assumptions: (1) the activity durations are crisp numbers; (2) each working day has the same working hours; (3) the activities are preemptive; (4) every activity can start at any time point during the working hours. In this study, a project on high-quality workbench casting and technique development is used as an example to illustrate how to conduct temporal analysis and project scheduling with fuzzy activity durations, when the activities have different working hours and characteristics. For the convenience in project scheduling and control, we uses Microsoft Excel to conduct the parameter analysis of PERT and the critical chain scheduling. This not only makes the calculation more convenient and easier to understand but also meets the constrained extension principle naturally. |
