研究模糊环境下可追加订购的报童问题.假设需求量、追加定购的价格等均为模糊变量,在本金有限制的条件下,以极大化收益为目标,建立一个模糊机会约束规划,并将模糊随机模拟、神经元网络及遗传算法相结合,给出一个混合智能算法来求解该模型,从而得到最优订购量及追加的最大定购量.最后给出了数值例子.
The reordering newsboy problem was researched under the uncertainty circumstances. Under the constraints of cost, chance-constrained programming model for reordering newsboy was established assuming that demand and reordering's values were both fuzzy varieties. The optimal ordering and the optimal reordering were provided by the hybrid intelligent algorithm which combined by Fuzzy simulation, NN and GA. Finally, an example was given.
