| Abstract: |
| Objective To select the most optimal equipment maintenance contractor scientifically. Methods Comprehensive evaluation indexes of equipment maintenance contractors were proposed. A selection and evaluation model in which comparable and single linguistic expressions were used simultaneously was established. At first, the weight of each index was calculated by the method of analytic hierarchy process. Then, the indexes of alternative contractors were evaluated by composite linguistic expressions. Next, the composite linguistic expressions were transformed into hesitant fuzzy linguistic term sets (HFLTS), and the fuzzy envelope of HFLTS was reckoned by ordered weighted averaging (OWA) operator. At last, the best contractor was evaluated and selected by technique for order preference by similarity to ideal solution (TOPSIS). Results The applicability and the effectiveness of this model were verified by an example. Conclusion It provides the military with significant model reference on choosing the best equipment maintenance contractor. |
