多产品的最优(s,S,p)策略受系统的初始周期的库存水平和需求状态的影响,对多产品的需求状态做出合理的预测是优化库存和定价的关键问题。以多元马尔可夫模型为理论导向,建立了多产品的需求预测模型,并通过该模型确定了各种产品的需求之间的关系。同时,进一步证明了多产品的最优(s,S,p)策略的存在性,进而结合算例给出模型的最优策略的数值解。
The multi-product optimal (s, S, p) strategy is influenced by the inventory level and the demand state of the initial cycle of the system. Making a reasonable prediction of the multi-product demand state is a key issue for optimizing inventory and pricing. Based on multivariate Markov model theory, a multi-product demand forecasting model is established, and the relationship between various product requirements is determined through the model. At the same time, the existence of the optimal (s, S, p) strategy for multi-product is further proved, and then the numerical solution of the optimal strategy for the model is given.
