Correlation analysis of scheduling risks based on BN-CPM

Project scheduling depends on various risk factors,and they should be related by certain relationships that are usually represented by a correlation matrix in the existing methods.The practical difficulty is that,however,in some cases this matrix is too complicated to evaluate.This paper introduces a new approach and develops a BN-CPM model that incorporates the project network and risk factors into a Bayesain network for modeling uncertainty and relationship in project scheduling.Hence the new model can be used for calculation of the correlation between risk factors and also for analysis of schedule risks.It is a useful tool for managers to understand project risk factors and to improve their decision making.
