摘　　要：近年来,业内提出了货物运输客运化的运输组织模式思想,通过使用旅客列车的按图行车模式提高货运时效性,增强铁路货运产品市场竞争力。在集装箱班列客车化开行的情况下,停站和箱位预分方案是否合理直接关系到列车的满载率和收益。因此,以列车收益最大化为目标,构建集装箱班列客车化开行停站方案与箱位预分综合优化模型,提出列车沿途停站和各站的箱位预分方案。在建模过程中,通过引入虚拟弧和虚拟点构造停站方案决策变量,进而基于包含虚拟弧和虚拟点的广义网络构造目标函数和约束条件。针对模型中存在阶跃函数的问题,通过引入差异化惩罚参数和辅助变量,采用构造辅助约束条件的手段将模型转化为线性模型。最后通过算例验证了模型的可行性和求解效果。In recent years, some experts have put forward the idea of a new transportation organization, the passengerization operation of freight transportation, which makes freight cars operate in line with a train diagram to improve the timeliness and market competitiveness of railway freight transportation. Under the passengerization operation mode of container trains, their full load rate and income are directly related to the rationality of the stop schedule plan and container space pre-allocation.Therefore, an integrated optimization model was established for the stop schedule plan and space pre-allocation of container trains with passengerization operation to maximize train revenue. By introducing virtual arc and virtual point, the decision variables of a stop schedule plan were constructed, and then the objective function and constraint conditions were proposed with the generalized network including virtual arc and virtual point. Considering the step function in the model, this paper transformed the model into a linear one by introducing different penalty parameters and auxiliary variables and constructing auxiliary constraints. Finally, an example was given to verify the feasibility and solution effect of the model.
