博士 / 國立成功大學 / 工業與資訊管理學系 / 102 / An integrated production/delivery quantity problem in a make-to-order producer-buyer supply chain is analyzed in this thesis. The coordination policy is achieved by scheduling single setup at the producer with multi-delivery to the buyer. A per unit time cost model is developed and analyzed to determine the optimal production and delivery quantities. The cost model include setup cost at the producer, ordering cost at the buyer, inventory carrying cost at both echelon, and delivery cost, where the delivery cost is a function of the delivery quantities. Based on empirical transportation rate data it suggests that the delivery cost is in the general form of tapering or proportional function.
We analyze two cost models, where the delivery cost which costs belong to a class of proportional or tapering rates. The models include setup cost, ordering cost, inventory carrying cost, and delivery cost function of delivery quantity. Under some mild conditions, it can be shown that the joint cost function is convex with respect to the production quantity.
For the general transportation cost function (tapering and proportional) a fitted power function of delivery quantity is investigated. The cost model has been shown to be convex with respect to delivery quantity when the number of delivery is given; and it is also convex with respect to the number of delivery when the delivery quantity is given. A novel 2-D solution procedure is developed to quickly find the optimal decision policy. The mathematical analysis and computational study have demonstrated that significant cost savings can be realized by implementing the proposed approach into the network optimization process.
