Abstract: Food is the paramount necessity of the people, with the improvement of living standards, the importance of fresh agricultural products in the consumption structure is becoming more and more prominent. This paper introduces the idea of options into the supply chain of fresh agricultural products, for a two-level fresh agricultural product supply chain consisting of a supplier and a retailer, combining the natural attributes of fresh produce, considering the impact of in-transit loss on quantity and the impact of fresh-keeping inputs on freshness, the CvaR model is applied to study the influence of the retailer's risk aversion degree on the supply chain decision-making and the option contract coordination mechanism. The results show that the option mechanism can realize the risk sharing between the supplier and the demander, solve the coordination problem of fresh agricultural products supply chain under stochastic demand and distribute the whole profit rationally. The system coordination and pareto improvement can be achieved at the same time when the risk aversion of retailers is low.

Key words: fresh agricultural products, option, freshness, loss in transit, coordination

摘要： 民以食为天,随着生活水平的不断提高,生鲜农产品在消费结构中的重要性越来越突出,本文将期权思想引入生鲜农产品供应链运作当中,针对由一个零售商和一个供应商组成的二级生鲜农产品供应链,结合生鲜农产品的自然属性,考虑在途损耗对产品数量的影响以及保鲜投入对产品新鲜度的影响,运用CVaR模型研究了零售商的风险规避程度对供应链决策的影响以及期权契约协调机制。研究表明,期权机制可实现风险在供需双方之间共担,可解决随机需求下生鲜农产品供应链的协调问题并合理分配整体利润;仅当零售商的风险规避程度较低时系统协调和帕累托改进才能同时达成。
