【摘要】：随着市场经济的发展以及人民消费水平的提高,人们对农产品的要求发生了从量到质的转变。为推进优质农产品更加便捷地流通,农业部与商务部积极开展农超对接的推广工作。虽然农超对接模式的实施有助于减少农产品流通的中间环节,但目前我国农产品物流公共设施不完善,物流配送信息化程度低,以粗放型为主,网点的布局往往缺乏科学的规划,配送路线全凭主观意愿随意设定,缺乏合理的统筹安排,造成农产品物流配送效率十分低下。因此,如何制定合理的配送路线,实现对农产品更有效率地配送,是农超对接工作开展过程中必须要解决的重要课题。本文通过与国外现有农产品物流配送模式进行对比研究,在充分借鉴国外发达国家物流配送模式先进经验的同时,分析了我国现阶段农产品物流配送模式中暴露出来的一些问题。在此基础上分析了我国农产品物流网络优化的目标及方向,引入了传统的需求时变函数和反映农产品数量变化的损耗比例函数,避免了大部分研究只考虑车辆里程成本的情况,建立起了基于遗传算法的带有时间窗要求的配送路径优化数学规划模型,最后通过实例论证了该模型的可行性,并对模型的最终求解结果进行了分析。通过以上研究,得出结论:在农产品配送过程中,通过合理的路线规划,能够在提高物流运作效率的同时,降低物流配送的综合成本,同时满足人们对高品质农产品的需求。
[Abstract]:With the development of market economy and the improvement of people's consumption level, people's demand for agricultural products has changed from quantity to quality, in order to promote the circulation of high-quality agricultural products more conveniently. The Ministry of Agriculture and the Ministry of Commerce actively carry out the extension work of agricultural super docking. Although the implementation of agricultural super docking mode is helpful to reduce the intermediate link of agricultural products circulation, the public facilities of agricultural products logistics in China are not perfect at present. Logistics distribution information level is low, the main type is extensive, the layout of the network is often lack of scientific planning, distribution routes are all set by subjective will, lack of reasonable overall arrangement. Therefore, how to formulate a reasonable distribution route to achieve more efficient distribution of agricultural products. It is an important subject that must be solved in the process of agricultural super docking work. This paper makes a comparative study with the existing agricultural products logistics distribution mode abroad. At the same time, we can learn from the advanced experience of logistics distribution model in developed countries. This paper analyzes some problems exposed in the distribution mode of agricultural products logistics in our country at present, and then analyzes the goal and direction of optimizing the logistics network of agricultural products in our country. The traditional time-varying demand function and the loss ratio function which reflect the quantity change of agricultural products are introduced to avoid the fact that most of the researches only consider the cost of vehicle mileage. The mathematical programming model of distribution path optimization with time window is established based on genetic algorithm. Finally, the feasibility of the model is demonstrated by an example. Through the above research, the conclusion is drawn: in the process of distribution of agricultural products, reasonable route planning can improve the efficiency of logistics operation at the same time. Reduce the comprehensive cost of logistics distribution and meet the demand for high-quality agricultural products.
