摘　　要：为解决缓冲区设置不合理带来的项目间工序松弛、工期延误等问题,基于信息熵理论提出了一种关键链缓冲区设置方法.首先,提出了复杂熵、资源熵和人因熵的概念及其度量方法,运用熵的概念量化诸多不确定因素对工序造成的影响;其次,提出了基于区间直觉梯形模糊数的人因熵度量步骤与方法;最后,给出了工序工期、项目缓冲和汇入缓冲的熵模型与修正模型,充分考虑了人的行为因素对项目进度的影响,并通过算例验证了模型的实用性.In order to solve the problems caused by unreasonable buffer setting,such as process slacking and project delaying,this paper proposes a buffer setting method of critical chain based on information entropy.Firstly,it presents concepts and measurement method of complex entropy,resource entropy and human factor entropy,which are used to quantify the influence of uncertain factors on the process.Secondly,the steps and methods of human factor entropy based on interval-valued intuitionistic trapezoidal fuzzy numbers are proposed.Finally,fully considering the influence to project schedule of human behavior,it presents entropy models and modification models of procedure duration,project buffer and feeding buffer.The examples given in the end vividly convey the practicability.
