In this paper, proposing a mathematical model with disjunctive constraint system, and providing approximate membership function shapes to the optimal values of the decision variables, we improve the solution approach to transportation problems with trapezoidal fuzzy parameters. We further extend the approach to solving transportation problems with intuitionistic fuzzy parameters; and compare the membership function shapes of the fuzzy solutions obtained by our approach to the fuzzy solutions to full fuzzy transportation problems yielded by approaches found in the literature.

直觉模糊运输问题解的近似隶属函数形状

本文提出了一个具有析取约束系统的数学模型，并为决策变量的最优值提供近似的隶属函数形状，我们改进了梯形模糊参数运输问题的求解方法。我们进一步扩展了解决直觉模糊参数运输问题的方法。并比较通过我们的方法获得的模糊解的隶属函数形状，以解决文献中找到的方法所产生的完全模糊运输问题。
