摘要:
关键链在考虑资源约束条件下，较关键线路法具有显著的优越性，但由于受到各种不确定因素的影响，使得工序作业时间表现出随机性，从而导致关键链具有随机性．在采用传统方法识别出关键链基础上，应用期望与方差的性质和同分布中心极限定理，研究了关键链的期望工期和分布规律，以及在某指定工期下的完工概率．当有多条关键链时，选择完工概率最小的关键链作为重点控制对象．此方法对关键链的应用具有重要的指导意义．
Abstract:
The critical chain is obviously superior to the critical route method when considering the resource constraint. However, due to the influence of various uncertainties, the operation time is random, which leads to the random of the critical chain.Traditional method to identify the critical chain, based on the application of expectations and variance of the nature and the same distribution center limit theorem, to study the expected duration and distribution of the critical chain, as well as the probability of the completion of a specified period. When there are many critical chains, the key control object is the critical chain of the least completion probability. This method has important guidance for the application of critical chain.
