Coordination Research On Fresh Agricultural Product Supply Chain Based On Stochastic Demand

In recent years,although the advanced technology has achieved a great development on the modernization of agriculture and has ensured the information distribution channels’ clear to timely release the demand and supply information and sale price of fresh agricultural products,fresh agricultural product is a kind of special product that is different from the industrial processed products,the production cycle is longer,the yield is highly vulnerable to natural disasters and adverse weather and as the number of physical characteristics of fresh agricultural products with its own long-term preservation,not long-distance transportation will reduce the fresh agricultural products to shore and freshness,the season remaining after the residual value of fresh agricultural products have low or zero,fresh these agricultural products can not avoid the adverse factors have greatly hindered the agricultural structural adjustment and transformation and upgrading.In view of the current situation of the aquaculture species,in consideration of the research on supply chain coordination of fresh agricultural products is composed of a single supplier and a single retailer,when how to design the corresponding strategies to deal with changes in market demand and stochastic factor distribution respectively changes,in order to reduce the adverse effects of dynamic demand for fresh agricultural products supply chain profit,realize coordination the purpose of fresh agricultural products supply chain.Firstly,this paper studies the supply chain coordination of fresh agricultural products when the demand distribution function changes.Because of the fresh agricultural products supply chain keeps a state of coordination on share in the original revenue sharing contract,considering the disturbance makes the production cost and market demand and changes,proposed an improved revenue sharing contract,to reasonably distribute the participating members due to disturbance caused by the sale of risk or sales revenue in the supply chain,to achieve the fresh agricultural supply chain of agricultural products coordination.Through the establishment of profit function model,the optimal probability theory and other related mathematical knowledge to solve the payoff function solution in order to determine the revenue sharing contract of supply chain related parameters,the participating members of the supply chain system to the optimal management strategy,and it is proved that when the disturbance factor changes within a certain range when the revenue sharing contract is robust to supply chain coordination;and when it is beyond a certain range,the revenue sharing contract to make the necessary improvements can still coordinate the supply chain.Secondly,the coordination of fresh agricultural products supply chain with random factor distribution function is studied.The freshness and loss of fresh agricultural products have an impact on the retailer’s expected return based on present,consider the function relationship between the product market demand and response to the quality of agricultural products freshness and transportation process loss,and set a random factor to reflect the market demand changes.The function model between the construction of market demand and freshness,and the loss rate of random factors and the introduction of inventory factor,design a random factor associated with the revenue sharing contract,discusses the optimal inventory factor stability under the condition of optimal decision,and each member of the supply chain in the system under the coordination of the.Then when the random disturbance factor distribution is subject to unexpected events,so the size of the market demand will also be disturbed under the disturbance of the supply chain coordination sharing under contract is destroyed in return,we need to put forward an improved revenue sharing to achieve supply chain coordination to deal with emergencies by contract.Finally,based on the distribution function and the distribution function of the random factor disturbance respectively from the market demand,the author summarizes the research contents and results,whether the market demand distribution function changes or market demand due to changes in distribution function of random factor changes,the revenue sharing contract is robust to the fresh agricultural products supply chain,and improved revenue sharing contract can coordinate to achieve supply chain.In the two cases,the risk sharing and revenue sharing can be realized,the stability of the supply chain is improved,the competitive advantage of the fresh agricultural products is enhanced,and the income of each member of the supply chain is improved.Finally,this paper puts forward the lack of research and the direction of the next work.
