Abstract:

The group decision-making trial and evaluation laboratory (DEMATEL) is a commonly used method of factor analysis in complex systems, which can reveal causal relationship among the factors. In recent years, the group DEMATEL has been widely used in various fields. As a DEMATEL expansion method of how to solve complex hierarchical structure problems, hierarchical group DEMATEL has attracted the attention of some experts and scholars. However, existing hierarchical group DEMATEL methods still have the following deficiencies such the inherent “method-structure” mismatching, logical confusion and fragmentation of the correlation among the different levels of factors, as well as the expert judgments being difficult. To overcome the above-mentioned drawbacks, a group DEMATEL factor analysis method with hierarchy-situation type for complex systems is suggested in this paper. In the method, a new analytical structure is first proposed by devising the state situations of the system factors and adding multiple alternative situations. Then, the factor knowledge reasoning mechanism from a holistic perspective is given based on polychromatic set theory. Next, the corresponding method implementation steps are given in detail. Finally, a case study on the identification of risk factors affecting oil and gas leakage from offshore platforms is shown to illustrate the proposed method and verify the feasibility and validity of the proposed method. The result shows that the method is scientific and reasonable and can be well applied to solve the issue of analysis of complex system factors. It should be noted that this suggested method not only clarifies the action mechanism of group DEMATEL complex factors reflecting well hierarchical structure characteristics from both vertical and horizontal dimensions, but also can realize the varying weight analysis of the system factors.
