【摘要】:針對(duì)快遞企業(yè)的配送車輛在城市配送過(guò)程中空載嚴(yán)重的問(wèn)題,在多家快遞企業(yè)實(shí)施共同配送的前提下,考慮車輛同時(shí)取送貨對(duì)車輛裝載率的影響,以配送系統(tǒng)總成本最小化為優(yōu)化目標(biāo),建立考慮同時(shí)取送貨的城市共同配送路徑優(yōu)化模型,并設(shè)計(jì)改進(jìn)遺傳算法進(jìn)行求解,最后通過(guò)算例分析驗(yàn)證了模型和算法的實(shí)用性與有效性。
[Abstract]:In view of the serious problem that the distribution vehicles of express delivery enterprises have no load in the process of urban distribution, under the premise that many express delivery enterprises carry out joint distribution, the influence of vehicle delivery at the same time on the loading rate of vehicles is considered. With the objective of minimizing the total cost of distribution system, the optimization model of urban joint distribution path considering simultaneous delivery is established, and an improved genetic algorithm is designed to solve the problem. Finally, the practicability and validity of the model and algorithm are verified by an example.
