基于限制优势关系的航天装备备件品种确定

航天装备备件品种确定是实现航天装备精确保障的重要基础。针对航天装备备件品种确定过程中决策信息不完备、犹豫性、模糊性等特点突出的问题, 提出基于限制优势关系的备件品种确定方法。引入犹豫模糊集和粗糙集理论, 建立备件品种确定的犹豫模糊决策信息系统, 基于限制优势关系实现决策属性的约简和决策规则的获取, 构建基于限制优势关系的备件品种确定模型, 最后以某航天测控装备为例进行了案例分析与应用, 证明了方法的可行性与有效性。

Variety determination of spare parts for space equipment based on the relationship of limited advantages

The variety determination of spare parts for space equipment is an important basis for accurate support of space equipment.In order to solve the problem of incomplete decision-making information,hesitation and fuzziness in the process of determining,the variety determination of spare parts based on the relation of limited advantages is proposed.Hesitant fuzzy set and rough set theory are introduced to set up the varieties of spare parts to determine the hesitation of fuzzy decision information system.Based on the limited advantages relation decision attribute reduction and decision rule acquision,the model of the spare parts variety determination based on the limited advantages relation is built.Finally,the space tracking and control station equipment is taken as an example for case analysis and application to prove the feasibility and effectiveness of the proposed method.
