多目标模糊运输问题的建模与求解

The Modeling and Solution of Multi-objective Fuzzy Transportation Problem

  • 摘要: 为了研究信息不完整、不确定条件下的运输问题, 建立了目标函数费用系数、供应量和需求量均为三角模糊的多目标模糊运输问题(MOFTP)模型。通过选用三角模糊数的大小关系将模糊目标函数转化为传统的目标函数, 同时根据模糊数的数学特征将模糊等式约束转化为对应的不等式约束, 然后对转化后的目标函数和约束条件进行整合, 从而建立与多目标模糊运输问题等价的多目标线性规划模型, 其最优解即为原多目标模糊运输问题的最优解。最后通过具体算例, 证明了模型求解方法的可行性。

     

    Abstract: In order to study the transportation problem under the condition of incomplete and imprecise information, a multi-objective fuzzy transportation problem(MOFTP) is established.Its cost coefficients, source coefficients and destination parameters are represented by triangular fuzzy numbers.Fuzzy objective functions are transformed into classical multi-objective functions according to the ordering method for triangular fuzzy number.At the same time, equality constraints are transformed in to inequality constraints in the light of definition of triangular fuzzy number.And then, multi-objective linear programming problem equivalent to MOFTP is established after integrating transformed multi-objective functions and constraints.At last, a numeric example is presented to illustrate the applicability of the approach proposed.
