Abstract: Considering stochastic consumer demand,the paper studies coordinated supply-production-distribution plan problem in mufti-tier supply chain network from suppliers to end consumers.A mufti-period two-stage stochastic programming model with resourse problem is constructed according to the assumptions and analysis of the problem,which aims to wholly optimizing supply-production-distribution.The solving strategy is also brought forward for the stochastic model by hybrid optimization and simulation.Finally,a demonstration analysis is given to validate effectiveness of the model by using simulated data.The difference of cost is compared on supply-production-distribution plan adopting the synchronous and asynchronous ways: The distributional characteristic of cost is analyzed about supply-production-distribution plan under stochastic and deterministic mean demand.The computational result shows that the coordinated supply-production-distribution plan model under stochastic demand can remarkably reduce the total supply chain cost as well as efficiently control the quantity of supply-production-distribution and decrease the inventorv so as to depress the market risk for customer's demand fluctuation.
