基于Vague集理论的IT项目挣值管理

Earned Value Management of IT Project Based on Vague Sets Theory

挣值管理是项目管理中广泛采用的一种管理方法,论文探讨将质量管理因素纳入传统的挣值管理之中。基于质量管理中不确定因素的客观存在,论文借助Vague集理论描述项目实施过程中的不确定因素,并借助Vague值表达项目监控点各个工作包的质量达标情况。通过Vague值的基本运算规则得到项目监控点的质量达标程度,进而得到了新的挣值计算公式。论文的研究成果,一方面丰富了项目管理中挣值管理的内涵,使其具有更强的适应性,另一方面也为Vague集理论拓展了应用空间。

Earned value management is a management method widely used in project management. The control factor of quality management is discussed in this paper. Based on the uncertainty factors in the quality management, Vague sets theory is used to describe the uncertain factors in the process of project implementation. Meanwhile, standard quality situation of each work package is expressed by Vague value. With the basic operation rules of Vague values, the project quality standard of monitoring points is obtained. Then, the new formula of earned value is gotten. The research results, on the one hand, enrich the connotation of earned value management and improve its adaptability, on the other hand also extend the application space of Vague sets.
