ABSTRACT

In this paper, aiming at the problem of ordering and transportation of raw materials in existing production units, the entropy method is used to establish a comprehensive capability evaluation model to reflect the importance of suppliers, and the important suppliers are screened out from the model. First of all, four indicators of average supply intensity, supply accuracy, order rate and supply stability are established as dependent variables of entropy method to evaluate the importance of suppliers, and the top 50 suppliers are obtained. Then considering that the selection of the least suppliers should not only meet the production needs of enterprises, but also ensure the stability of production, but also meet the business principle that the lower the cost, the better. Taking the maximum supply capacity of the supplier as a fixed value as the predicted value of its supply capacity in the next 24 weeks, taking this value as the decision variable and the ordering cost as the objective function, a 0-1 integer programming model is introduced to solve whether each supplier is selected or not. To solve the number of 1 in the 0-1 matrix is to solve the minimum number of suppliers.
