The Research Of Ordering And Pricing Problems In The Supply Chain With Shipment

With the rapid development of economic globalization, increasing competition amongcompanies has evolved into a competition between the supply chain. In addition, thediversification, rapid marketization of the product demand increases the difficulty of thecompanies’ provision, whether the product is timely replenishment and adequate will affect thecompanies’ market competitiveness largely, so companies need to cooperate with each other andoptimize ordering, transportation and other sectors.This thesis studies the ordering and pricing problems with transportation from theperspective of the supply chain. It is respectively studied from three aspects:when the productdemand is identified and price-sensitive, free transportation costs under minimum orderingquantity. Then we establish their own relevant mathematical models, use some optimizationmethods to solve the decision variables and propose concrete examples to verify the results ofthe analysis. This thesis is organized as follows:In chapter1, we introduce some concepts related to the supply chain, and the current mainresearch results at home and abroad.In chapter2, when the product demand is identified, we study the problem on the optimizingordering and shipment policies in the supply chain with lead-times. Under the assumption ofconstant rate of demand, shortages permission with the buyer and the distribution of deliverylead-times, we can establish both the vendor and the buyer’s cost function models undercooperation and non-cooperation, then derive the optimal policies under the objection ofminimizing the cost. At last, it is easily proved that cooperation can save the costs of the entiresupply chain through the results of numerical example.In chapter3, when the product demand is price-sensitive, we study the problem on thepricing and ordering policies in the supply chain with credit option during the lead time. It isassumed that the demand is price-sensitive, shortages is allowed, the delivery lead-times isuniform distribution and the vendor provides credit payment. We establish both the vendor andthe buyer’s profit function models under cooperation and non-cooperation, and analyze theordering and pricing policies under the objection of maximizing the profit. Finally an example is adopted to validate the model.In chapter4, we study the model of free transportation costs under minimum orderingquantity. We assume that the product demand of the buyer is price-sensitive and the buyer orderthe product according to the EOQ models, on the other hand, the vendor determine the minimumordering quantity if the buyer wouldn’t bear the transportation costs. It is mainly discussed thatwhether the buyer add ordering quantity when the optimal order quantity of the buyer is less thanthe minimum ordering quantity of the vendor, so that the buyer needn’t bear the transportationcosts.In chapter5, we present the conclusions and outlook.
