A Study on Computerized Simulation of difference between CPM and CCPM

摘要

The constant delays of projects demonstrate that traditional project planning methods may adopt an inefficient way to manage uncertainty. To tackle problems in traditional project system, CCPM (Critical Chain Project Management) was introduced by Goldratt(1997) to identify both task dependence and resource conflicts as main constraints within a project[1]. This method is characterized by applying Theory of Constraints in project management and inserting buffers to deal with uncertainty. Although CCPM have demonstrated certain success and is regarded as an alternative of traditional project planning technique, lots of projects still suffer from considerable failure. Given the condition that CCPM is still under doubt and has not been applied widely, this paper conducts investigation about difference between CCPM and CPM/PERT based on computerized simulation of case study.
