Review Jurnal Green supply chain management using the queuing theory to handle congestion and reduce energy consumption and emissions from supply chain transportation fleet Link jurnal http://www.jiem.org/index.php/jiem/article/view/2170 Abstract Purpose: Nowadays, governments and people pay more attention to use green products due to environmental pollution, irreplaceable energy and shortage of resources. Green products are resulted from the application of green supply chain management strategies to the organizations' performance strategies, so that we can reduce environmental pollutants and wastes and take a step towards saving energy with limited resources. Methodology: In this paper, the effect of reducing energy consumption in green supply chain is examined by using queuing theory and transportation models. Data was generated and solved by a commercial optimization epackage. Findings: The findings indicate that suitable assignment of existing tra...
