Research on the Multi-Attribute Engineering Risk Factors Identification and Evaluation Index System Quantification

摘要

The establishment of criteria for selection, classification, and evaluation of engineering risk identification factors is the foundation of and the key to risk assessment. Approaches and methods for qualification of risk classification and of evaluation criteria are put forth in line with quantification theory (Hayashi IS) on the basis of research into such qualitative analysis techniques as expert survey, questionnaire survey, literature review. The multi-attributes of engineering risk are explored from both prospective of genetic factors and influencing factors. Moreover, a method of multivariate scaling is proposed to solve the problem of valuation of reaction scale for factors of complex international projects. Furthermore, a quantified model is established of engineering risk identification factors and evaluation criteria, and computer applications are applied to solve and analyze the model, with the aim to satisfy needs of different management departments for identifying and evaluating risks.
