Although the existing critical activity concept and its identification method are valid for projects without resource constraints,they are not very valid for resource-constrained projects,especially in situations involving more than one unit of renewable resource.

Optimization scheduling research of multi-resource-constrained project based on mixed-intelligence algorithm;

After reviewing the development history and researching actuality of RCPSP, this paper brings forward a new heuristic ? a MIN-Q based heuristic for multi-resource constrained project scheduling problem combining with CPM and seriation optimization theo.
