摘 要: 通过对运输决策问题中基本情况的研究,对运力有限情况下单个需求点单一物资运输方案进行分析,考虑运达概率、损失度对运输优化的影响,采用优化技术,以运输时间有限、每批货物运输的损失度小于规定的上限和成功运达的可能性高于规定的概率为约束条件,供应点最少、损失度最低为目标建立运输优化数学模型。利用Matlab编写0—1整数规划函数linprog01�m和调用其优化工具箱中非线性约束最优化函数fmincon对模型进行求解,得出了最优运输方案,验证了Matlab强大的数值计算能力对一类运输优化问题求解的有效性。
关 键 词: 综合运输;优化;供应点;运达概率;损失度;Matlab

Abstract: This paper analyzes how to transport one type goods to a station considering the limited transportation ability after researching a certain basic instance in the transport decision�making issue, and establishes the optimization mathematical model taking limited transport time, loss degree of each batch of goods lower than upper limit and successfully carrying probability higher than prescriptive probability as constraint condition, and using optimization technology on the goal of the least supply depot and the lowest loss degree. The paper has compiled 0—1 integer programming function linprog 01.m using Matlab, and called non�linear constrained optimization function fmincon in Mablab optimization toolbox to solve the model. It proves to be efficient by an example based on the Matlab and concludes the optimization transportation plan.
Key words: integrated transportation; optimization; supply depot; successfully carrying probability; loss degree; Matlab
