Abstract

With the increasing awareness of consumers’ low-carbon preferences and the implementation of government energy-saving and emission reduction policies, designing supply chain networks solely based on economic benefits is no longer sufficient to meet the development needs of enterprises. Moreover, the drawbacks of traditional supply chain network design that only considers the goal of maximizing profits or minimizing costs are becoming increasingly prominent. To this end, this study proposes a sustainable supply chain network structure for industrial production, which includes a dual-objective planning function model that maximizes profits and minimizes emissions, and a closed-loop supply chain network framework based on the product life cycle. The optimal solution of the function is obtained by using the Non-dominated Sorting Genetic Algorithms-II (NSGA-II) based on elite strategies after the improvement of immune operators. Empirical results show that the average values of time index (198), convergence measure (0.34) and interval index (623) in the improved NSGA-II algorithm are better than in other algorithms and this algorithm has clearer explanation for the decisions it made. It is also effective in helping companies choose emission reduction technologies and low-cost production facilities. With the improved algorithm, the total cost as well as carbon emissions can be reduced. The research method provides a new perspective for carbon emission management and sustainable development, and offers practical solutions for enterprises to reduce their carbon footprint and allocate resources reasonably in production and supply chain management. It helps to improve supply chain resilience and achieve sustainable development goals under economic development.
考虑碳减排的工业生产可持续供应链网络设计
随着消费者低碳偏好意识的增强和政府节能减排政策的实施,单纯从经济效益出发设计供应链网络已不足以满足企业的发展需求。此外,传统供应链网络设计只考虑利润最大化或成本最小化目标的弊端也日益突出。为此,本研究提出了一种可持续的工业生产供应链网络结构,包括以利润最大化和排放最小化为目标的双目标规划函数模型和基于产品生命周期的闭环供应链网络框架。在对免疫算子进行改进后,采用基于精英策略的非支配排序遗传算法- ii (NSGA-II)求解该函数的最优解。实证结果表明,改进后的NSGA-II算法的时间指标(198)、收敛测度(0.34)和区间指标(623)的平均值均优于其他算法,对所做决策的解释更加清晰。在帮助企业选择减排技术和低成本生产设施方面也很有效。改进后的算法可以降低总成本和碳排放。研究方法为碳排放管理和可持续发展提供了新的视角,为企业在生产和供应链管理中减少碳足迹、合理配置资源提供了切实可行的解决方案。它有助于提高供应链弹性,实现经济发展下的可持续发展目标。
