Fuzzy comprehensive assessment in electric power optical cable line based on the uncertain AHP
Lu Shan · Power System Protection and Control · 2009
In order to better combine the expert experience and quantitative calculation,meanwhile,successfully deal with uncertainties in electric power optical cable line reliability assessment indicators and vague of experts’ judgment,an Uncertain Analytic Hierarchy Process is introduced and applied to fuzzy comprehensive assessment in electric power optical cable line.According to many experts determined interval judgment matrix,the optimized weight values were made by using the group judgment and collected value statistic and center of gravity decision method.The comment scores are fuzzed through membership function of fuzzy theory and construct fuzzy matrix,finally we will gained the quantities evaluating result by adopting fuzzy comprehensive assessment technology.An instance is given to prove the feasibility of using the method in electric power optical cable line reliability assessment.
