研究随机需求条件下带时间窗的IRP问题的数学模型,并借助遗传算法来求解这一模型。以某物流公司配送系统为例,获得了路径安排和库存策略的优化目标解。实验结果表明这不仅能明显减少迭代次数,而且可以改善优化计算结果。
研究隨機需求條件下帶時間窗的IRP問題的數學模型,併藉助遺傳算法來求解這一模型。以某物流公司配送繫統為例,穫得瞭路徑安排和庫存策略的優化目標解。實驗結果錶明這不僅能明顯減少迭代次數,而且可以改善優化計算結果。

This paper presents a mathematical model of stochastic demand inventory routing problem with time windows (IRPTW). A genetic algorithm is introduced to solve the model. It aims at optimizing the solution to both route arrangement and inventory strategy, by taking a logistic company delivery system for example. The findings show that it can not only reduce the iterations, but also improve the optimization results.
