实践表明 ,对状态变量的递增量较大的报童问题 ,应用传统的离散型报童模型所确定的最优决策量与实际最优方案之间可能存在较大偏差 .分析了这一偏差出现的原因 ,提出了状态变量递增量较大的情况下的离散变量报童模型和求解方法 ,并证明这一模型比原模型得出的求解结果更为精确 .最后 ,通过算例验证了新模型对原模型的改进 . The practice shows that for the newsboy with larger increment of state variables, there may be a big deviation between the optimal decision-making amount and the actual optimality determined by the traditional discrete newsboy model.Analysis of the causes of this deviation , Proposed the newsboy model and the solution method of discrete variables with larger increment of state variables and proved that this model is more accurate than the original model.Finally, improvement of .
