容差法在带模糊约束最小费用流问题中的应用

Allowance Law Applying in the Minimum-cost Flow Problem with Fuzzy Constraint

文献[1]首先提出了带模糊约束最小费用流问题的数学模型.但是对于“虚拟运价”中参数θ没有给出具体的方法.本文使用“容差法”对“虚拟运价”重新进行了研究,由于最优水平值可以通过模糊综合评判法或灰色综合评判法来给定,这样确定的“虚拟运价”就更科学,而且更适于实际操作.

The reference (1) firstly proposed the minimum-cost flow problem with fuzzy constraint, but for parameter in “Imaginary transportation cost”, it didn’t list the resolution methods .How, this essay restudies the “Imaginary transportation cost” by applying “Allowance Law”. Since the best value can be judged by fuzzy rudiment method and grey comprehensive rudiment method, this method will be more scientific and more suitable for practical operation.
