模糊计划评审技术及其在软件工程中的应用

M-PERT and the application of the software engineering

对软件工程提出一个新的计划评审方法.这一方法以模糊数学理论为基础,项目的每一工序时间用模糊数来描述,项目的总完成时间按模糊数的运算来计算,它克服了经典PERT方法中每一工序时间服从β分布,项目的总时间服从正态分布的假设的局限性.最后将此方法成功地应用于某停车场管理系统的开发中.

A new PERT in software engineering is presented in this paper.It is based on fuzzy mathematical theory; every procedure time of project was described by the fuzzy data,and summated by fuzzy computer.It overcomes the localizations of sutra PERT: β-distributing obey to every procedure time and suppose normal distribution to sum time.This method is given following by a successful application to a certain Parking System.
