Abstract: For the project schedule management problems, the critical chain project management Bayesian network model (CCPMBN) based on the critical chain project management and Bayesian network technologies was established. Firstly, the definition of CCPMBN was proposed and the nodes, edges and conditional probability distribution of nodes in CCPMBN were described in detail. Secondly, the critical chain procedure breakdown algorithm was demonstrated and the CCPMBN modeling method was established based on the critical chain. Thirdly, the resource conflict mode in critical chain and corresponding solutions were discussed. Finally, the basic properties and characteristics of CCPMBN verify its advantages in project schedule management.
