【摘要】 鲜活农产品供应链是指在鲜活农产品生产、流通过程中所涉及到的生产资料供应商、生产商、分销商、零售商以及最终消费者连成一体的功能网链结构模式。农超对接是国外普遍采用的一种农产品供应链模式,而我国目前只有15%左右。因此,本文将研究收益共享契约下传统鲜活农产品供应链协调以及农超对接模式下鲜活农产品供应链协调。首先分析了鲜活农产品供应链模式和存在问题。指出鲜活农产品的易腐易变质性和时鲜性两个重要特点,以及我国鲜活农产品供应链的两种重要模式,并探讨了鲜活农产品供应链存在着组织化程度低、各节点成员间的信息共享严重不足等问题。接着针对一个由生产商-分销商-零售商构成的鲜活农产品三级供应链,在考虑损耗和新鲜度的影响下,通过引入库存因子,分别求出三种不同决策情形下的供应链最优期望利润的解以及收益共享契约协调下供应链成员的利润分配。结果表明:收益共享契约能有效地协调三级鲜活农产品供应链,契约参数在一定范围内可实现三方共赢,且最优期望利润随着需求价格弹性k的增加而减少。最后以数值算例说明结果的正确性。最后,考虑了鲜活农产品在运输途中有一个短的生命周期,从而构造了新鲜度因子以及一个反映鲜活农产品数量变化的损耗比例函数,并构造了利用对数函数反映新鲜度对需求的影响。研究了时间约束下收益共享契约对一个生产商(如生产基地)和单个零售商(如超市)组成的鲜活农产品供应链的协调作用。更多还原

【Abstract】 The fresh and live agricultural product supply chain consists of suppliers, producers, distributors, retailers, and consumers. It is fused function network model. Connecting agriculture with supermarkets is a widely used fresh and live agricultural product supply chain in foreign country, while only 15% in our country. So this paper will research the fresh agricultural supply chain coordination under both situations by revenue-sharing contracts.This paper firstly analyzes the fresh produce status and existing problems of agricultural supply chain, pointing out the two important characteristics: perishable product and fresh and live product. There are two important models in the fresh and live agricultural product supply chain. Then, there is the low level of organization, each node in the sharing of information between members of a serious shortage of uncertainty and instability in the fresh and live agricultural product supply chain.Then, this paper studies a three-level fresh and live agricultural product supply chain consisting of producer, distributor, and retailer. We identify the optimal expected profits of the chain under three different decision-making scenarios with the consideration of product loss, freshness and stocking factor. In addition, we analyze the coordinated profit distribution among all three chain members in accordance with revenue-sharing contracts. We obtain these findings: revenue-sharing contracts coordinate the three-level supply chain in question effectively; correctly selected contract parameters can lead a win-win result for all three parties; and the optimal expected profits decrease with the increase of demand price elasticityk . Finally, we provide a numerical example to support the findings.Finally, this paper considers fresh and live agricultural products have a short life cycle in transition. Then we construct the freshness factor, and a number of changes reflecting the loss of fresh agricultural products, the proportion of function and logarithm function is constructed by reflecting on the needs of freshness Impact. We study a two-level fresh and live agricultural product supply chain consisting of producer, and retailer in the time constraints of a revenue sharing contract.更多还原
