Improved Fuzzy Evaluation Model of Military Supply Chain Performance Based on Variable Weight

Abstract

According to the characteristics of military supply chain, we design the indicator of performance evaluation based on the key factors of supply chain strategy in this paper. When talking about estimating performance evaluation, in order to materialize the punitive or stimulant request that decision-maker performs towards decision-making factors, but constant weight synthesis method can’t fulfill the request, so an improved fuzzy evaluating model based on hierarchy variable weight is put forward. Introduction Military supply chain is a new kind of logistics support mode, adapting to the needs of the development of the information war and network war [1]. It puts together purchase, stock, transportation and ultimately armies, which brings the advantages of the supply chain into full play and gains the maximum benefits of the supply chain. In order to evaluate the integrated effect of military supply chain and improve the performance of military supply chain, reasonable evaluation methods and appropriate evaluation indicators should be adopted to get the feedback information timely in the process of military supply chain management[2]. Traditional performance evaluation methods of supply chain include linear weighted method, multi-objective fuzzy evaluation, probability and statistics based ways, etc [3], which give reasonable evaluation results in most circumstances. However, two main drawbacks lie in the traditional methods: the value setting of indicators and the weighting of each indicator. Generally, the values of most indicators for evaluating the performance of the military supply chain are hard to set quantitatively. Moreover, the lower value of one single indicator will greatly reduce the overall performance whereas the higher value of one single indicator will not necessarily make the overall performance increased significantly. Therefore, the indicator’s weight should change with the evaluation value where penalty weight should be larger than the awarding value. In this paper, a fuzzy evaluating model based on variable weight and corresponding indicators concerning three key factors of military supply chain strategy are proposed. The indicator system of performance evaluation In order to evaluate the performance of supply chain, many scholars have proposed various evaluation indicator systems. These indicator systems can be largely divided into three categories: SCOR, balanced score card and ROF (resource, output and flexible) [4,5]. However, most of these index systems is introduced based on enterprise supply chain and may not apply to the military supply chain. The indicator system of military supply chain performance evaluation must establish according to its own characteristics [6]. By reviewing international and domestic supply chain performance evaluation index system, we list out the key factors (resource, output, and the flexible) of supply chain strategy on which the indicator of performance evaluation are based, and break them down into detailed sub-items. Based on these detailed sub-items, we design our performance evaluation indicator system (see Fig.1) according to the characteristics of military supply chain.
