Key spare parts management plays an important role in equipment management. To ensure the quality of equipment maintenance, the quality of spare parts must be guaranteed. So the evaluation problem of similar spare parts supplier must be solved effectively, by which the management and optimization of key spare parts can be realized. Firstly, the mathematic model of key spare parts evaluation is introduced in detail. Then based on the principle of AHP, the algorithm of key spare parts evaluation is established, which consists with four step: (1)establish AHP model; (2)construct comparative judgment matrix; (3)calculate the weight ranking and matrix consistency judgment under single rule; (4)calculate synthetic weight relative to target layer of element at each layer. It is a method of qualitative analysis and quantitative analysis on complex decision-making problems. Finally the specific example was given, and the result showed its effectiveness.
