【摘要】：随着居民生活品质的提升,消费者对于生鲜农产品的需求逐步扩大,对其新鲜度的要求也在同步增长。与此同时,随着电子商务融入人们的日常生活,网上购物成为一种潮流趋势,生鲜农产品在网购产品中的比例也越来越大。生鲜产品与其他消费品最大的不同点是其易腐特性,且产品腐败造成的损失成本非常高,这也使得生鲜农产品的研究与其他产品研究存在本质差异。本文以生鲜农产品作为研究对象,首先分析生鲜产品性质及其物流现状,将生鲜农产品电商共同配送与传统超市配送进行对比,指出共同配送的优势并以此为背景进行建模。其次,将双层规划作为建模工具,分别站在物流规划者角度和消费者角度,考虑物流成本和客户满意度这两个相悖目标,对应建立上层成本模型和下层满意度模型。上层模型中,将共同配送过程中涉及的成本进行量化,并以新鲜度作为主要惩罚标准,构成选址成本模型。下层模型中,将客户对网点距离的满意度作为重点研究因素,建立满意度模型。再将上下两层问题进行结合,共同构成终端配送网点的选址模型,并采用启发式算法对模型进行求解,求得最佳的终端网点选址方案。最后进行算例分析,并对产品腐败率进行敏感度分析,验证生鲜农产品的腐败率改变将会影响其最终选址方案的确定,以此证明模型的实用性。
[Abstract]:With the improvement of residents' quality of life, consumers' demand for fresh agricultural products is expanding gradually, and the demand for freshness is also increasing. At the same time, with the integration of e-commerce into people's daily life, online shopping has become a trend, fresh agricultural products in the online purchase of more and more large proportion. The biggest difference between fresh products and other consumer goods is their perishability, and the cost of loss caused by product corruption is very high, which also makes the research of fresh agricultural products and other products have essential differences. In this paper, fresh agricultural products as the research object, first of all analysis of the nature of fresh products and the current situation of logistics, fresh agricultural products electronic distribution and traditional supermarket distribution comparison, pointed out the advantages of joint distribution and modeling based on this background. Secondly, using bilevel programming as a modeling tool, taking logistics cost and customer satisfaction into consideration from the perspective of logistics planners and consumers respectively, the upper cost model and the lower satisfaction model are established. In the upper layer model, the cost involved in the joint distribution process is quantified, and the freshness is the main penalty standard to construct the location cost model. In the lower model, the satisfaction degree of customer to the distance between nodes is taken as the key research factor, and the satisfaction degree model is established. Then the upper and lower layer problems are combined to form the location model of terminal distribution network and the heuristic algorithm is used to solve the model to obtain the best terminal node location scheme. Finally, a case study was carried out, and the sensitivity analysis of the product corruption rate was carried out to verify that the change of the corruption rate of fresh agricultural products would affect the determination of the final site selection scheme, thus proving the practicability of the model.
