CONSTRUCTION OF SPARE PARTS IMPORTANCE EVALUATION FOR CROSS-REGION HARVESTER BASED ON CRITIC AND TOPSIS METHOD

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.
