ABSTRACT

In this paper, an improved optimization model and a matching algorithm based on priority decision are established to gradually optimize the ordering and shipping schemes, so as to achieve the purpose of reducing costs.First of all, topsis comprehensive evaluation model based on entropy weight method is established to determine the index weight, and the ranking of 402 suppliers is carried out. Finally, the top 50 most important suppliers are obtained through index scores.Then, the maximum capacity optimization model is established by constructing capacity threshold and referring to the maximum transshipment volume of the transporter and the supply quantity of the supplier. After calculation, the maximum capacity is 33,240 m³, which is 17.87% higher than the initial capacity.
