摘　　要：对传统的运输问题进行了改进,研究了费用系数为模糊参数和需求为随机条件下的优化问题,构建了模糊随机运输问题的数学模型。通过引入机会约束规划对此模型进行确定性转化,使得决策成立的条件不小于某一给定的置信水平,再通过置信水平将机会约束规划转化为相应清晰的等价类。最后,通过数值算例,验证了模型的可行性,探讨了不同置信水平对最优解的影响。The paper improves the traditional transportation problem, studies the optimal problem with fuzzy parameter and stochastic variable and establishes a mathematical model of fuzzy stochastic transportation problem. By introducing chance constraint programming, it transforms the model into a deterministic one to make sure that the condition found is at a given confident level and then transforms the chance constraint programming into its deterministic equivalent formulation. Finally, it shows an example.
