A technical conditions evaluation method for power system with analytical hierarchy process

In order to provide guidance and reference to the research on the design of ship power system and the ship-ping maintenance support. The basic characteristics of technical conditions for power system and the essentiality of evalu-ation method are analyzed, and the evaluation parameters and indexes of technical conditions for power system are discussed in the paper. The evaluation model of technical conditions is established with the Analytical Hierarchy Process combined with the characteristics of the main equipment for power system, the qualitative and quantitative analysis of the weight of each index is carried out in the evaluation method. In the last, the analysis result is in accord with the actual situation of real ship with analytical hierarchy process. Experimental results show that the technical conditions evaluation method for power system is scientific and valuable.
