| Abstract: | A mathematical programming model under stochastic constraints for activity net-works and its equivalent deterministic linear model are discussed. The stochastic duration and critical path on minimal probability level can be solved from the model. The criteria for deter-mining critical path of networks with different characteristics is given. The reason for existing significant error of PERT/CPM algorithms is also revealed. |
