Abstract:As a new project schedule management technology, critical chain can effectively solve many problems such as uncertain factors interference and frequent resource conflicts in multi-project schedule management. In this paper, the research of multi project management based on critical chain technology is reviewed. First, we introduce the critical chain theory, analyze and summarize the characteristics of multi-project management and the multi-project management process based on critical chain. Then, we sort out and review three aspects, namely, the multi project scheduling model and solution based on critical chain, the improvement of key problems in scheduling and the application in management practice. Finally, the future research direction of the multi-project management based on critical chain is prospected.
