Abstract: Classic schedule monitoring methods for critical chain projects focus only on the consumption of time buffers, ignoring the impact of resource consumption on the project schedule. In order to solve the problem of the instability of monitoring effect caused by different buffer sizing methods in the critical chain project management, a new schedule monitoring method based on project resource segmentation is proposed in this paper. First, all the required project resources are divided into three types on the basis of resource characteristics. Second, the warning state values of according resources are determined by the multi-objective fuzzy comprehensive evaluation method to minimize the objective function. Finally, the follow-up resource consumption of the project is predicted by BPNN, so that the issues arising from the project implementation can be handled timely and comprehensively. The experiment results show that the proposed method can reduce the overdue completion rate and the production-capacity-surplus rate by means of effectively predicting the risk status of the project.
