摘要
主要给出一类目标函数的系数、供应量和需求量均为区间数的多目标运输问题模型,根据参数的实际意义和区间数的序关系,针对所建立模型,利用区间规划的方法,将其转化为确定型的多目标运输问题,最后用模糊规划技术处理等价的多目标运输问题.数值例子表明算法的有效性和可行性.
This paper presents a multi-objective transportation problem where cost coefficients of the objective functions, and the source and destination parameters have been expressed as interval values. According to significance of parameter in the fact and based model, As a result an MITP was transformed into an exact linear MTP. Finally, the equivalent transportation problem has been solved by fuzzy programming technique. A illustrative numerical examples are provided to illustrate the approach.
