先采用CPM方法计算出项目的关键线路和工期，但是CPM方法没有考虑各种资源对施工的约束，往往与实际不符，而基于关键链方法，可以获取到工程施工过程中的资源约束下的关键链。实际上，施工过程中需要的各种资源又受到某些外界因素的影响，使得这些工序的完成呈现出一定的概率性。所以，本文将随机过程的思想和方法应用到最优关键链的获取中，最终找出最优的施工线路和施工工期。该方法对后续的工程施工具有重要的指导意义。

The CPM method is first used to calculate the critical path and duration of the project .But the CPM method does not consider the constraints on the construction of various resources .When the methods are based on the critical chain , the critical chain on the construction process of resource constraints is ob-tained.In fact, a variety of resources required in the construction process are influenced by some external factors.The completion of these processes exhibits a certain probability .Therefore, ideas and methods of stochastic processes are applied to obtain the optimal critical chain .Eventually , the optimal critical chain and duration are calculated .The method is of significance to guide the actual construction .
