造船企业信息化项目的风险识别方法

A Risk Identification Method of the Information Project in Shipbuilding Enterprise

针对造船企业信息化特点,提出将故障树分析法与工程分解结构–风险分解结构(WBS-RBS)相结合的风险识别方法.该方法通过WBS-RBS建立的耦合矩阵来判断造船企业信息化中可能存在的风险因素,并根据故障树的建树规则和各风险因素间的逻辑关系建立造船企业信息化的主要故障树,通过改进的风险检查表得到各风险因素发生的概率.在此基础上,对各风险因素进行重要度分析.最后,举例验证上述风险识别方法的可行性和实践性.

According to the characteristics of shipbuilding enterprise informatization, a risk identification method com- bining the fault tree analysis and the work breakdown structure and risk breakdown structure （WBS-RBS） is presented. The method established by WBS-RBS determines the coupling matrix in which shipbuilding enterprise informatization risk fac- tors may exist, and builds the major fault tree based on the rules of the fault tree and the logical relationship of the risk factors in shipbuilding enterprise informatization. The probability of the occurrence of each risk factor is obtained by the improved risk checklist. On this basis, the importance of the risk factors is analyzed. Finally, an example is presented to prove that the above risk identification method is feasible and practical.
