CRITICAL CHAIN PROJECT SCHEDULING: UTILIZING UNCERTAINTY FOR BUFFER SIZING

In this paper, we introduce a method for buffer sizing in Critical Chain project scheduling. Proposed approach considers lognormal distribution for modeling activities’ execution time. The inherent uncertainty of activities considered as a main factor to size the buffer in proposed method. For comparing with traditional methods we used problems presented in literature. The results depict that proposed method outperforms critical chain buffer sizing method.
