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...
Review Jurnal Pengembangan Model Variable Review Period dengan Mempertimbangkan Order Crossover link jurnal : http://jurnalindustri.petra.ac.id/index.php/ind/article/view/18967 Abstract: In this paper, we propose a variable review period model using dynamic programming for order crossover problem. The proposed model is compared to an existing variable review period model and classical review period in terms of minimum inventory cost. The simulation is applied with six scenarios and sensitivity analysis is also done. The results show a variable review period model performs smaller inventory cost for small variation of lead-time compared to classical review period model. On the other hand, classical periodic review model is sensitive with the changes in the variation of demand distribution and service level. The proposed model gives the better solution compared to variable review period model for the six scenarios with the inventory cost saving as 11-42%. The sensitivity...
