基于复合语言表达的装备维修合同商评价与选择

目的科学选择最优装备维修合同商。方法提出装备维修合同商的综合评价指标,建立一种同时使用比较语言和单一语言表达的装备维修合同商选择评价模型。利用层次分析法确定指标权重,采用复合语言对备选合同商的各项指标进行评价,将复合语言转换为犹豫模糊语言术语集(HFLTS),通过有序加权平均(OWA)算子计算HFLTS的模糊包络,最后应用逼近理想点(TOPSIS)法进行了合同商的评价和选择。结果通过实例验证了该选择方法的实用性和有效性。结论为军方合理选择最优装备维修合同商提供了重要模型借鉴。

Assessment and Selection of Equipment Maintenance Contractor Based on Composite Linguistic Expressions

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.
