Design of multi-objective mathematical model of crashing PERT networks using genetic algorithm

Abstract

In this paper, a nonlinear multi objective mathematical model forcrashing the PERT network is presented. The main purpose of thismodel is minimizing the pessimistic time of critical activities byallocating more budget. In fact, this model indicates how the budget isallocated among critical activities. The results show that decreasingthe pessimistic of critical activities lead to decreasing the time andvariance of project completion. This model increases the probabilityof project completion on time scheduling. A genetic algorithm is useto solve the nonlinear model
