基于熵权的TOPSIS法在企业原材料选择中的评价研究
Research on the Assessment of TOPSIS Method Based on Entropy Weight in Enterprises’ Selection of Raw Materials

在激烈的市场竞争环境下，企业想要实现效益最大化，必须从供应链管理的角度出发保障企业内部的生产制造流程，将供应链各个流程紧密连接以提升企业市场竞争力。本文以2021年数学建模竞赛C题为例，根据企业订购的原材料必须满足每周的生产需求，评价和选择402家供应商，建立供应商评价模型，利用熵权法确定指标的权重，并运用TOPSIS法计算各供应商的评分，得到不同供应商对企业保障生产的重要程度，制定出效益最大化的原材料订购方案，实现企业效益最大化。
In the environment with fierce market competition, an enterprise that wants to realize benefit maximization has to start from the angle of supply chain management to safeguard its internal production and manufacturing processes and closely connect every process in the supply chain to enhance its market competitiveness. The author of this article takes Question C in the mathematical contest in modeling of 2021 as an example, evaluates and selects 402 suppliers on the basis that raw materials purchased by the enterprise should satisfy its weekly production requirements, builds the supplier evaluation model, utilizes the entropy weight method to determine weights of indexes, applies the TOPSIS method to calculate the score of every supplier, obtains the importance of different suppliers for safeguarding the production of the enterprise, and draws up the raw ma-terial procurement scheme for benefit maximization in order to realize benefit maximization for the enterprise.
