带软时间窗的生鲜水果冷链物流配送路径优化

Optimization of Cold Chain Logistics Distribution Path of Fresh Fruit with Soft Time Window

随着人们生活水平的提高,生鲜水果已成为人们生活饮食中非常重要的一部分,人们本着吃得安全健康的观念,对其运输保存过程非常关注。但在对生鲜产品进行配送时,有时会出现成本高、货损严重以及不准时等问题,更使冷链产品配送物流商承受着巨大的压力。本文以东莞市百果园凤岗配送中心为例,建立了在车辆、载重、能源、时间等条件约束下的带软时间窗的生鲜水果冷链物流配送路径优化模型,并通过蚁群算法进行模型求解,证实该模型的合理性与可行性。

With the improvement of people’s living standards, fresh fruit has become a very important part of people’s diet. People pay great attention to its transportation and preservation process based on the concept of safe and healthy eating. However, in the distribution of fresh products, sometimes there are problems such as high cost, serious cargo damage and untimely, which makes the cold chain product distribution logistics providers bear great pressure. Taking the Dongguan Baiguoyuan Fenggang distribution center as an example, this paper establishes the optimization model of the logistics and distribution path of fresh fruit cold chain with soft time window under the constraints of vehicle, load, energy, time, etc.Finally, in order to prove the rationality and feasibility of the model, the model is solved by ant colony algorithm.
