In response to violent market competition and demand for low-carbon economy, cold chain logistics companies have to pay attention to customer satisfaction and carbon emission for better development. In this paper, a biobjective mathematical model is established for cold chain logistics network in consideration of economic, social, and environmental benefits; in other words, the total cost and distribution period of cold chain logistics are optimized, while the total cost consists of cargo damage cost, refrigeration cost of refrigeration equipment, transportation cost, fuel consumption cost, penalty cost of time window, and operation cost of distribution centres. One multiobjective hyperheuristic optimization framework is proposed to address this multiobjective problem. In the framework, four selection strategies and four acceptance criteria for solution set are proposed to improve the performance of the multiobjective hyperheuristic framework. As known from a comparative study, the proposed algorithm had better overall performance than NSGA-II. Furthermore, instances of cold chain logistics are modelled and solved, and the resulting Pareto solution set offers diverse options for a decision maker to select an appropriate cold chain logistics distribution network in the interest of the logistics company.
为应对激烈的市场竞争和低碳经济的需求,冷链物流企业必须关注客户满意度和碳排放,以实现更好的发展。本文考虑经济、社会和环境效益,建立了冷链物流网络的双目标数学模型;也就是说,优化冷链物流的总成本和配送周期,总成本由货物损坏成本、冷链设备的制冷成本、运输成本、燃料消耗成本、时间窗口的罚款成本和配送中心的运营成本组成。提出了一种多目标超启发式优化框架来解决这个多目标问题。在该框架中,提出了四种选择策略和四种解集接受标准,以提高多目标超启发式框架的性能。从比较研究中可知,所提出的算法具有比 NSGA-II 更好的整体性能。此外,对冷链物流实例进行建模和求解,所得的 Pareto 解集为决策者提供了多种选择,以有利于物流公司选择合适的冷链物流配送网络。
