【摘要】：冷链物流是指在冷藏环境下为了保证食品质量,减少食品在运输中的损耗,以冷冻工艺为基础、以制冷技术为主要手段,进行冷藏类食品的物流过程。物流过程包括采摘、分级预冷、包装加工、配送和批发零售等环节。随着经济的发展,国力的强盛,人们的生活水平也得到改善,从而对鲜活农产品等的需求量也越来越大,特别是对产品品质的要求越来越苛刻。这就对冷链物流的配送提出了更高的要求。在我国,冷链物流尚处于起步阶段,它不仅面临着前所未有挑战,同时也面临着千载难逢的机遇。本文以冷链物流为研究对象,考虑以下几个方面的内容:第一,在硬件方面,本文基于ZigBee无线传感网络和GPS定位技术,设计了冷链运输车的远程监控系统。此系统可以对整个物流运输过程实施数据的动态采集、传输和报警,从而实现管理者对车辆的有效控制和调度。第二,从配送站的角度出发,以配送成本的最小化(即配送站利益最大化)为目标,对影响成本的具体因素进行了详细分析,并考虑城市交通的拥堵成本,本研究构建了城市冷链物流配送车辆路径问题的数学模型,利用启发式算法进行模型求解,并结合实例对算法的合理性和可行性进行分析。第三,运用多智能体软件Netlogo进行了多配送站竞争合作局面下的仿真,分析了如何才能更好的节约成本,通过合作扩大各个配送站的效益。
[Abstract]:Cold chain logistics refers to the logistics process of refrigerated food in order to ensure the quality of food and reduce the loss of food in transportation under the cold storage environment. The logistics process includes picking, taking refrigeration technology as the main means and freezing technology as the basis. With the development of economy and the prosperity of national strength, people's living standard has also been improved, thus the demand for fresh and live agricultural products is also increasing. In particular, the requirements for product quality are becoming more and more stringent. This puts forward higher requirements for the distribution of cold chain logistics. In China, cold chain logistics is still in its infancy, and it is not only facing unprecedented challenges. This paper takes cold chain logistics as the research object and considers the following aspects: first, in hardware, this paper is based on ZigBee wireless sensor network and GPS positioning technology. The remote monitoring system of cold chain transport vehicle is designed. This system can dynamically collect, transmit and alarm the data of the whole logistics transportation process, thus realize the effective control and dispatch of the vehicle by the manager. Second, From the point of view of distribution station, aiming at minimizing the distribution cost (that is, maximizing the profit of distribution station), the specific factors affecting the cost are analyzed in detail, and the congestion cost of urban traffic is considered. In this study, the mathematical model of the urban cold-chain logistics distribution vehicle routing problem is constructed, and the heuristic algorithm is used to solve the model, and the rationality and feasibility of the algorithm are analyzed with an example. Third, The multi-agent software Netlogo is used to simulate the situation of multi-distribution station competition and cooperation, and how to save cost better and expand the benefit of each distribution station through cooperation are analyzed.
