Aiming at the low accuracy of index weight calculation and risk type identification in traditional cost risk management systems, this paper proposes a project cost risk management system based on an improved fuzzy rule weight algorithm. We analyzed the types of project cost risks, adopted a three-tier technical architecture to design the system frame structure and functional organization structure of the cost risk management system, and adopted the B/S architecture for network structure deployment. In the software part, an improved fuzzy rule weight algorithm is used to calculate the weight of project cost risk indicators, thereby improving the effectiveness of risk management. Experimental results show that the designed system works well, can accurately calculate the weights of risk indicators, and can effectively identify multiple risk types.

基于改进模糊规则权重算法的项目成本风险管理系统设计

针对传统成本风险管理系统中指标权重计算和风险类型识别精度不高的问题，提出一种基于改进模糊规则权重算法的项目成本风险管理系统。我们分析了项目成本风险的类型，采用三层技术架构设计成本风险管理系统的系统框架结构和功能组织结构，采用B/S架构进行网络结构部署。在软件部分，采用改进的模糊规则权重算法计算项目成本风险指标的权重，从而提高风险管理的有效性。实验结果表明，所设计的系统运行良好，能够准确计算风险指标的权重，能够有效识别多种风险类型。
