| 摘 要： | 以空车总走行里程为最小目标,以空车供需平衡为约束条件建立空车调配数学模型;通过vba蝙程调用Lingo软件解决空车调配问题;对具体的算例分别运用震荡法和vba调用Lingo方法进行求解,并时求解结果进行分析.研究结果表明.运用vba调用Lingo方法不仅操作简便,而且在运算时间和精度上都具有显著的优越性,调用后的系统,在数据录入与结果输出方面都比原始Lingo数据读取与输出更容易操作,更直观,是解决大规模空车调配问题的有效工具,具有实际应用价值.

| Abstract: | Considering total traveling mileage of empty vehicle to be minimum as target,this paper was based on the balance between supply and demand for the empty vehicle as distribution constraints to establish mathematical mode and then used vba program to call Lingo software to solve the empty vehicle deployment problem.According to practical examples, Oscillometry and method of calling Lingo by vba were used respectively to analyze the solution.The results showed that the use of vba by the approach of calling the... |
