易腐品生产运输协调决策模型

he integrated production-distribution decisions have very important practical significance under the background of supply chain, is also a hot issue for researchers in recent years. This article, on the basis of previous studies, by introducing the concept of system safety stock and system inventory, develops an integrated production-distribution model; and prove that the structure of the optimal sequence of shipments must be monotone nondecreasing and vendor must send all inventory out at first replenishment point; then proposes a new transport strategy. The objective of this article is maximize the supply chain profit and to find the optimal sequence of shipments, the optimal production time and the optimal numbers of delivery in integrated production-diAn optimal policy for a integrated production-distribution model for deteriorating itemsstribution model under the new transport strategy we put forward. Numerical examples are provided to illustrate the proposed model.
