A New Progress in the Theory of PERT
This paper put forward the concept of “quasi-critical path and related four theorems. We proved that each has a quasi-critical path related with it. By “ dependent quasi-critical path we mean that for this , there must be a path preceding it and for all activities in the path their free slacks are zeros. Similarly, there must be a path succeeding it and for all activities in the path, their backward free slacks (a new concept!) are zeros. The difference between a “critical path and an “ dependent quasi-critical path is: For the “critical path, there are no time slacks. For the “ dependent quasi-critical path, there are no free slacks in the activities preceding this and no backward free slacks in the activities succeeding this. For important activities with uncertain time we need to calculate their “ dependent quasi-critical path to guarantee enough time for them.
