Abstract: To improve the decision level and application scope of Critical Chain Method(CCM), the multi-mode CCM was studied. By integrating multi-mode network planning with critical chain technology, the implementation procedure of multi-mode CCM was presented. The mathematical model of multi-mode critical chain project scheduling problem was fomulated by considering resource constraints, multi-mode activities and uncertain activity duration. Based on traditional serial scheduling generation scheme, the heuristic algorithm was given combined mode priority rules with activity priority rules. The multi-mode project data in PSPLIB were used as testing instances to test common combinations of activity priority rules and mode priority rules fully. The results showed that Least Total Resource Usage (LTRU) activity priority rule and Greatest Resource Demand (GRD) mode priority rule had excellent performance in multi-mode critical chain project scheduling problem with different scale.
