Abstract

Project risk evaluation is the basis of project risk management, and it is the sticking point of the successful project implementation. In this paper, a group decision making approach based on multi-granularity linguistic assessment information is used to evaluate the project risk. The linguistic 2-tuple representation model and computing model are taken for dealing with multi-granular linguistic assessment information. Firstly, the experts linguistic assessment information is represented in the form of 2-tuple. Secondly, the basic linguistic term set is chosen from multi-granularity, linguistic term sets and the computational formulae are given to uniform the multi-granular linguistic assessment information into the normalized representation of the 2-tuple linguistic. Then, the experts' weights in each attribute are obtained, and the group evaluation results of the project risk are determined according to an optimization model. Finally, a numerical example of ERP project illustrates the effectiveness of the proposed approach.

基于语言评价信息的项目风险评价方法

项目风险评价是项目风险管理的基础，是项目成功实施的关键。本文采用基于多粒度语言评估信息的群体决策方法对项目风险进行评估。采用语言二元组表示模型和计算模型处理多粒度语言评价信息。首先，将专家语言评价信息以二元组的形式表示。其次，从多粒度中选择基本语言项集，给出语言项集和计算公式，将多粒度语言评价信息统一为二元组语言的规范化表示;然后，得到专家在各属性中的权重，根据优化模型确定项目风险的群体评价结果。最后，通过一个ERP项目的算例说明了该方法的有效性。
