为解决需求区间型运输问题,将弹性需求区间转化为三角模糊数,建立该问题的模糊优化模型;根据运输问题的特点,将模糊优化模型转化为两个等价的运输问题,给出模糊最优判决λ＊的一个定理,并给出此类运输问题的一种简便求解方法;最后,通过实例验证方法的有效性.%To solve the transportation problem with interval of the demands,the intervals of demands are translated into triangular fuzzy numbers,and the fuzzy optimization model for this problem is established.According to the characteristic of transportation problem,the fuzzy model is equivalent to two traditional transportation problem.A theorem for fuzzy optimal decision λ＊is given.Finally,an example illustrated the effectiveness of the method.
