Research On Option Contract Supply Chain Of Fresh Agricultural Products With Freshness Loss And Freshness-keeping Effort

With the development of the economy and the increasing of people's quality of life,the proportion of fresh agricultural products are gradually increasing in people's lives,people are now studying how to achieve its efficient circulation.However,as a perishable product,the fresh agricultural products have the characteristics of being easily wasted in the circulation process.The freshness of the product is easily affected by the external environment and have a certain life cycle.Therefore,high requirements are imposed on the management of the supply chain of fresh agricultural products,the scholars' research focus have become how to reduce losses in the circulation process and reduce the risk of the supply chain effectively.The research directions of scholars are mainly how to achieve supply chain coordination.Fresh agricultural products as a perishable product,the article conducts research based on the loss of fresh produce.Firstly,the article analyzes the supply chain decision-making of fresh agricultural products under the condition of wholesale price contract.Then it introduces the option contract in the supply chain,the model discusses the ordering strategies under two kinds of decisions and discusses the situation that suppliers are allowed to run out of stock under decentralized decisions,and determines the optimal ordering strategy of the retailer and the optimal supplier.At the same time,the corresponding contract parameters are determined to achieve the coordination of the fresh agricultural products supply chain.Finally,As the freshness preservation efforts can reduce quantity loss and increase market demand,the article introduces freshness effort into option contracts,the freshness effort combines market demand function,quantity loss function and freshness function,when freshness effort is invested in the fresh agricultural products supply chain,it can improve the freshness of fresh agricultural products and stimulate the market demand,which is line with the reality.At the same time,the article determines the contract parameters to achieve the coordination of the fresh produce supply chain.This article establishes an option contract model based on the consideration of quantity loss,the option contract can reduce the operating cost and operating risk of the supply chain.At the same time,it considers the freshness effort to combine the quantity loss function,market demand function and freshness function,which is line with the actual reality.The research in this article makes up to a certain extent the deficiencies of the traditional fresh agricultural product supply chain and fresh agricultural options research.The research in this article makes up to a certain extent the deficiencies of the traditional fresh agricultural product supply chain.It is conducive to enrich the content of academic theory and provides a new perspective for the fresh agricultural products supply chain research,which has certain theoretical value and practical significance.
