Network Planning Method with Imprecise Activity Durations
具有不精确活动周期的网络计划方法

The problems of computing the time parameters and evaluating criticality of activities in networks with impre- cise activity durations are very difficult and have never been solved in a fully satisfactory manner in the past.So,the new polynomial algorithms for determining the intervals of the time parameters in general networks are proposed,and the criticality of activities can be evaluated by their floats.Finally,a solvable case is present,and then the results are extended to networks with fuzzy activity durations.
