A Buffer Sizing Approach in Critical Chain Scheduling with Attributes Dependent

Three attributes relevant to a specific project, including the number of activities in chain, the uncertainty of activities duration and the flexibility of activities start time, were introduced into critical chain project management for sizing buffer. By means of simulation research, the impact of these three attributes on project scheduling in terms of two performance indicators: project duration and on time completion was evaluated. Based on the analyses of simulation experiment, a revised method for sizing buffer was proposed. The case indicates that the performance of project scheduling is significantly improved by using the revised method.
