Abstract

The invention discloses a supply chain based multi-period inventory optimization and management method. According to the method, a downstream node enterprise adopts a (s,Q) production policy for production and inventory control; and at the same time, a corresponding dynamic inventory model is also constructed for a midstream node enterprise, and an upstream node enterprise cooperates with the downstream node enterprise, so that the sum of inventory expenses of the whole supply chain is reduced maximally. The method is different from the situation that the node enterprises in a non-cooperation state only pursuing maximum reduction of inventory cost. With the adoption of the method, the optimal production preparation period, the optimal production period and the optimal production capacity of the whole supply chain within a production cycle can be obtained at the same time.

Description

technical field [0001] The invention relates to a supply chain-based multi-period inventory optimization management method, belonging to the technical fields of logistics engineering and supply chain management. Background technique [0002] The supply chain is centered around the core enterprise. Through the control of information flow, logistics and capital flow, it starts from purchasing raw materials, making intermediate products and final products, and finally delivering products to consumers through the sales network. At the same time, it also connects suppliers, Manufacturers, distributors, retailers, and end users are connected into a whole functional network chain structure. It can be seen from the definition of supply chain that an enterprise is a node in the network model, and there is a demand-supply relationship between node enterprises. The complexity of the supply chain is also reflected in the large number of member companies with different scales and capabi...
