This paper introduces the milk-run schema into the express distribution logistics through the feasibility analysis of application of cyclic goods-taking schema in the express industry. In order to reach fully loaded as far as possible in distribution, the article improves the traditional model, adopting multi-objective decision and conforming constraint conditions to Milk-run schema, even approximating the practical truth solves model through the C-W saving algorithm. It can effectively shorten the distance and Lower costs by means of reasonable route planning. Finally, the paper has verified the model and its effectiveness of arithmetic application by means of cases analysis.
This paper introduces vendor managed inventory model into agricultural product supply chain which the agricultural cooperatives and supermarkets are directly connected with and achieves coordination by option contract. We find that the expected profit and the optimal order quantity of supply chain under decentralized decision-making situation are less than the levels of centralized decision-making situation and there's double marginalization in this system. Our research demonstrates that option contract can coordinate the agricultural cooperatives and supermarkets and achieve a reasonable distribution of profits between them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
