A Research On Storage Capacity Planning And Allocation Problem Of Logistics Enterprise

At present enterprises A who is in company JC is facing supply chain integration opportunity. As the only a logistics enterprise in the group, the ability of A enterprise to plan logistics in order to meet the demand of enterprises within the group, will become the crucial factor of the success in the integration of supply chain.This paper looks A enterprise as the research object and uses the theory and method of supply chain management, planning of ability, inventory control, real option, etc to plan the storage capacity of A enterprise.While the capacity expansion was not considered in the research, the case of requirements determination with storage capacity constrained multi-product inventory model was built. Applying Lagrange multipliers method could obtain the optimal solution and inventory policy under the existing storage capacity. Found that storage capacity was constrained so that the optimal order quantity of the product and the economic order quantity decreased significantly via the research.In the research with considering the case of capacity expansion, in view of the storage capacity could be purchased or built, construction of storage capacity was not only a constraints but also multi-product inventory model of the decision variables with the algorithm and the optimal solution. Results compared with the last chapter, found that only under the condition of the storage capacity of the shadow price was higher than the expansion of the cost of business expansion would be better, and after the expansion of the shadow price was equal to the expansion costs，companies could maximize profits.In addition, the paper take market uncertainty into account, build a storage capacity outsourcing mode using real options theory and find the optimal option predetermined amount through the optimization method. Then the paper use the way of numerical example to prove that outsourcing strategy can reduce the storage capacity of the spot market price volatility brings enterprise risk in certain conditions, increase the expected return, improving the flexibility of enterprise storage capacity greatly.
