Abstract

Aiming at the problem of insufficient research on the importance evaluation of agricultural machinery spare parts in the process of cross-region operation of combine harvester, Based on CRITIC and TOPSIS, an evaluation model of the importance of spare parts for cross region combine harvesters was established. The CRITIC model was used to calculate the weight of each evaluation index, the weighted TOPSIS evaluation model was used to process the data, and the relative closeness between the spare parts of each harvester to be evaluated and the ideal solution was calculated. Finally, the spare parts resource management decision-making system platform is developed to effectively integrate the spare parts resource allocation. The results show that the model can reasonably and effectively evaluate the important demand degree of combine har-vester spare parts, and has a good reference value for the cooperative service of agricultural machinery service vehicles and the priority degree of spare parts loading.

针对联合收割机跨区作业过程中，农机备件重要度评价研究不足的问题，建立了基于CRITIC和TOPSIS法的跨区作业联合收割机备件重要度评价模型。运用CRITIC模型计算得到各评价指标的权重，运用加权TOPSIS 评价模型对数据进行处理，并计算各待评价收割机备件与理想解的相对贴近度。建立联合收割机备件重要需求度评价指标体系, 最后开发备件资源管理决策系统平台，有效的将备件资源配置进行集成管理, 模型能够较合理有效地对联合收割机备件重要需求度进行评价，对农机服务车的协同服务，备件装载优先度有较好的参考价值。
