Study On Modeling And Optimization Of Inventory Costs Of Single-cycle Supply Chain

The inventory problem is an important part of the supply chain. In the supply chain management environment, inventory optimization is an effective way to reduce the supply chain cost.In this paper, based on an in-depth study of the no discount and single-cycle supply chain, modeling and optimization of inventory costs of manufacturers and downstream manufacturers is given. This paper analyses the entire supply chain inventory cost, and makes a model, finds the optimal order quantity. Then, using an example of inventory cost analysis shows that through the entire supply chain inventory system to optimize the entire supply chain can reduce inventory costs.. An further research on a discount under the conditions of the supply chain inventory costs is given, and it analyses the entire supply chain inventory costs of no discount single-cycle supply chain, building models, which is much more complicated than the above-mentioned models. First to classify the discussion and then to solve, finally, find the best of all the possible orders Including of all discount points.Finally, the 2-tier supply chain inventory is extended to study the multi-tier supply chain inventory cost model. In the modeling, the first is to give the model of the upstream manufacturers, intermediate manufacturers and downstream manufacturers three inventory cost models of their own, and second to solve. Then, analyze and establish the model of the entire multi-tier supply chain inventory cost, the model is much more complicated than the 2-tier supply chain of inventory model, and then find the best order in the multi-tier supply chain under the conditions, and use Hessian matrix to prove that the solution is the optimal solution.
