随机产出与需求下考虑努力水平的生鲜农产品供应链协调研究OACHSSCD

The coordination of fresh agricultural product supply chains is a key pathway to reducing circulation losses and optimizing the matching of supply and demand.In response to the complex situation of overlapping stochastic output and demand,this paper constructs a three-level supply chain model composed of farmers,a single supplier,and a retailer,focusing on the coordination mechanism driven by dual efforts in production and preservation.By comparing centralized and decentralized decision-making models,this paper reveals that the total profit of supply chain members under decentralized decision-making is significantly lower than the system's total profit,highlighting an inherent contradiction.Based on this,an optimal decision-making framework centered on production effort,preservation effort,pricing,and order quantity is proposed.Further,a coordination optimization scheme combining a"revenue sharing+cost sharing"contract with risk-sharing strategies is designed to prove that this composite contract can effectively eliminate the double marginalization effect and bring the expected profit of decentralized decision-making to the Pareto optimal level of centralized decision-making.The research findings indicate that the realization of supply chain coordination depends on the precise positioning of member roles-suppliers can significantly increase the circulation scale of fresh agricultural products by deeply focusing on consumer utility,forming a win-win situation for all parties;enterprises'active sharing of farmers'production risks becomes a key lever to enhance the overall chain profit,and its risk compensation mechanism can simultaneously motivate farmers to increase production effort and product quality.This paper provides a"production-preservation-circulation"three-dimensional collaborative decision-making paradigm for the contract coordination of multi-level fresh agricultural product supply chains,offering theoretical support and practical references for mitigating the bullwhip effect in agricultural product supply chains and promoting the implementation of the rural revitalization strategy.
