Abstract

Currently, most countries are moving towards digitalization, and their energy consumption is increasing daily. Thus, power networks face major challenges in controlling energy consumption and supplying huge amounts of electricity. Again, using excessive power reduces the stored fossil fuels and affects the environment in terms of $ {\rm CO_{2}} $ emissions. Keep these issues in mind; this study focuses on energy-efficient products in an energy supply chain management model under credit sales, variable production, and stochastic demand. Here, the manufacturer grants a credit period for the retailer to get more orders; thus, the order quantity is related to the credit period envisaged in this model. Considering such components, supply chain members can reduce negative environmental impacts and significant energy consumption, achieve optimal results and avoid drastic financial losses. Additionally, including a credit period increases the possibility of default risk, for which a certain interest is charged. The marginal reduction cost for limiting carbon emissions, flexible production to meet fluctuating demand, and continuous investment to improve product quality are considered here. The global optimality of system profit function and decision variables (credit period, quality improvement, and production rate) is ensured through the classical optimization method. Interpretive sensitivity analyses and numerical investigations are performed to validate the proposed model. The results demonstrate that the idea of credit sales, flexible production, and quality improvement increases total system profit by $ 28.64\% $ and marginal reduction technology reduces $ {\rm CO_{2}} $ emissions up to $ 4.01\% $.

在可持续的供应链管理下保持能源效率和减少碳排放
目前,大多数国家都在向数字化迈进,能源消耗日益增加。因此,电网在控制能源消耗和供应大量电力方面面临着重大挑战。同样,过度使用电力会减少储存的化石燃料,并在二氧化碳排放方面影响环境。记住这些问题;本文研究了信用销售、可变生产和随机需求下的能源供应链管理模型下的节能产品。在这里,制造商授予零售商一个信用期以获得更多订单;因此,订单数量与该模型中设想的信用期有关。考虑到这些组成部分,供应链成员可以减少对环境的负面影响和显著的能源消耗,达到最佳效果,避免巨大的经济损失。此外,包括信用期增加了违约风险的可能性,因此要收取一定的利息。这里考虑了限制碳排放的边际降低成本、灵活生产以满足波动需求、持续投资以提高产品质量。通过经典的优化方法,保证了系统利润函数和决策变量(信贷周期、质量改进和生产率)的全局最优性。通过解释敏感性分析和数值研究验证了所提出的模型。结果表明,信用销售、灵活生产和质量改进的理念使系统总利润增加了28.64%,边际减排技术使系统的二氧化碳排放量减少了4.01%。
