摘要：

Project duration uncertainty has become a problem of project progress analysis. In particular, the duration of some project processes is in a very large range. In order to solve this problem, this article measures the uncertainty coefficient of the process based on the entropy method and calculates the definite duration of the project process. Then, this article introduces the project risk coefficient red line, based on the relative risk coefficient to establish the key chain buffer and non-key chain buffer setting model, setting the project buffer to calculate its duration. Combined with the example and compared with the shear-paste method, it proves that this method is more scientific, reasonable, and effective.
