Abstract: In the project practice, the project schedule would be prolonged due to resource constrained. Therefore, the paper first introduced a concept of resource time factor, adopts the design structure matrix(DSM), then described the demand on resources according to program by using resources into time factors DSM and resources exit time factors DSM. Finally, the author presents a genetic particle swarm algorithm for program schedule optimization based on resource time factor. The calculation proves that the method not only can reduce the Program Schedule, but also can provide decision-makers with a new perspective in proper increasing reasonable resources.

Key words: project management, resource constrained, resource time factor, design structure matrix, schedule optimization, particle swarm optimization(PSO)
