A Research On The Optimization Of Many Inventory Models Based On Agriculture Supply Chain

At the initial development stage, agriculture supply chain of our country aims for prompt reflection of the requirement and diminishment of the cost. Forasmuch of the inventory cost and the interrelated expenses make up of the main expenditure, inventory control takes an important part in the supply chain.Although the study of inventory control has been progressing rapidly, the inventory theory in agricultural supply chain is in the primary stage. The properties of farm products, such as perishableness and seasonality, make inventory control significant in agricultural logistics.Reviewing exiting concepts and theories about agricultural supply chain, a classification criterion is presented, in consideration of complexity, of compactification, of reliability, and of optimization.Based on existing EOQ, a new two-stage model and its solution are given. This model takes into account the seasonal variety of products demand. On top of that the expanded model, the multi-stage inventory is introduced.The cost of storage will be raised owing to the improper store or the bad transportation. With the corruptibility of the farm product, a model with deterioration rate is presented on the putrescibility of products. To save the cost of the whole supply chain and to heighten the operational efficiency, we often recommend the Third to deal with the storage. So a Third Inventory Model is discussed. With the seasonality of the product demand, there will be some OOS (Out of Stock), so we expound an optimal replenishment policy with backlogging.This article gives some models of inventory control and the solutions of the models, which prove adaptive to agricultural inventory.
