The Application of Fuzzy Multi-attribute Decision Making Method for Routing Scheme Comparison of Submarine Cables
摘要
Abstract
Multi indexes,which include both quantitative indexes and qualitative indexes,should be con-sidered in the selection of routing scheme of submarine cable,however,the incommensurability of these indexes gives a challenge in the scheme selection.In this paper,a hybrid multiple attribute decision making method based on deviation proj ection was introduced to choose the routing scheme of sub-marine.Firstly,the qualitative indexes were converted into triangular fuzzy number,reasonably quantifying the qualitative index,and a decision matrix was constructed.Then the weights of each index were calculated by the deviation maximization method,and the proj ection of each scheme on the positive ideal scheme and the negative ideal scheme was calculated.Finally,the degrees of rela-tive closeness were calculated,and then the closeness degrees were used to compare the routing scheme.Take one offshore wind farm construction project as an example,three routing schemes of submarine cables were compared by this method.It was found that the first scheme had obvious advantages in the cable length,investment,installation costs and the utilization of maritime space,etc.The conclusions were consistent with both the qualitative indicators and quantitative analysis, revealing that the method was feasibility and reliability in the selected of submarine cable routing scheme.关键词
