数量折扣条件下的动态订货批量优化
Optimization of Lot-Size for Dynamic Order with Quantity Discount
-
摘要: 为研究卖方提供数量折扣安排时,买方优化动态订货批量的决策问题,考虑多种产品、多折扣类型和买 卖双方的能力约束,建立了该问题统一的非线性混合整数规划模型.利用禁忌搜索技术设计启发式算法对模型 求解.算例的计算结果验证了模型和算法的有效性.Abstract: To optimize the lot-sizes for dynamic orders with quantity discounts offered by vendors, a non- linear mixed integer programming model was proposed. In the model, multi-products, multi-discounts and capacities constraints of the purchaser and vendors were taken into account. The model was resolved with heuristic algorithm based on Tabu search technique. The computational results of an example validate the effectiveness of the model and the algorithm.
