Research on Supply Chain Integrated Planning Model Based on Analytic Hierarchy Process and Optimization Theory

By analyzing the previous order quantity, supplier's supply quantity and transshipment homeopathy quantity, this paper designed the ordering scheme of raw materials for a building and decoration board manufacturer, and considered the transportation of raw materials. First of all, this paper finds four factors that affect suppliers: total supply quantity, supply times, supply satisfaction rate and average supply completion rate, determines the coefficient by AHP, and considers scoring, and selects 50 most important suppliers. Next, select the important suppliers from top to bottom, and order their historical maximum supply every week until the maximum production capacity is met. According to the order price, give priority to a and c, and reduce b. Finally, select materials with low loss and high transportation yield. Finally, the number of selected enterprises is increased, and the most Class A materials and the least Class C materials are purchased, so as to maximize the production capacity and minimize the losses while ensuring that one supplier is transported by only one forwarder.
