In order to quantify the support capability of logistics equipment and find out the weak links in the construction of logistics equipment, the support capability of logistics equipment is evaluated. The weight is determined by the combination of G1 method and entropy weight method, and the ratio of index importance determined by G1 method is replaced by the ratio of index difference coefficient of entropy weight method, which innovates the combination of subjective and objective weights. The evaluation model is established by cloud model, and the comprehensive evaluation cloud model is obtained by the comprehensive operation of index cloud model and index weight, and the evaluation result is determined by the comparison of cloud charts; By analyzing the evaluation results, it can be concluded that the overall support level can be significantly improved by improving the construction level of medical equipment, camping equipment, maintenance equipment and warehouse equipment. The results show that the evaluation method of logistics equipment support capability based on the improved combined weighting-cloud model is effective and feasible.
