目的 实现高压电器设备包装材料的优选，提高包装材料选择的一致性和经济型，降低制造成本。方法 建立一种多目标材料选择优选模型，包括包装承载力、包装可靠性、包装成本、资源消耗、包装绿色性等5个优化目标，使用组合隶属度函数构建评价指标集，运用灰关联法与基于可能度排序算法的模糊层次分析法相结合的方法，实现材料优选。结果 候选材料的关联系数分别为0.745、0.606、0.669、0.749。结论 关联程度最大的包装材料为最终优选包装材料。

The work aims to realize the selection of packaging materials for high-voltage electrical equipment, improve the consistency and economy of packaging materials selection, and reduce manufacturing costs. A multi-objective material selection model including five optimization objectives such as packaging bearing capacity, packaging reliability, packaging cost, resource consumption and packaging greenness was established. The evaluation index set was constructed with the combined membership function, and the material selection was realized by combining the grey crelational analysis (GRA) method with the fuzzy analytic hierarchy process (FAHP) based on the possibility ranking algorithm. The correlation coefficients of candidate materials were 0.745, 0.606, 0.669 and 0.749. The packaging material with the largest correlation coefficient is the final preferred packaging material.
