The main contributions are summarized as the following.Firstly, assuming demand is segmented by order lead time, a joint pricing and capacity allocation model is formulated considering scenario-based demand. Due to the stochastic discrete variable in the model, robust optimization is used to solve the model. Numerical examples prove our model and method reflect the stochastic characteristics of demand and provide more pratical pricing and capacity allocation policies than other methods of deterministic and stochastic expectation programming methods especially when the capacity is tight.
本文的创新之处概括为如下几个方面:首先,假设制造企业根据交货提前期对市场细分,建立了考虑需求情境的BTO模式下制造企业定价与能力分配的集成模型,利用稳健优化规划方法对此随机模型进行转化和求解,算例仿真表明随机优化规划方法较确定性规划和随机期望值规划方法更好地反映了随机离散需求的分布和波动特征,更加接近实际运作情况;产能越紧张,各类需求的价格差距越大,三种规划方法给出的最优策略差距越大。
