A Review of Manufacturing Operations Research Integration in Closed-Loop Supply Chains

HRMARS - This paper explores the integration of manufacturing operational potential research towards fulfilling supply chain closed-loop operations. A schematic research approach on the previous literature review is performed to identify the possibility of supply chain management integration starting from outsourcing decision. It also focusses on the simulation approach in addressing core supply chain management challenges such as production layout, product strategy, volume and variety. The paper also highlights the limitations of current simulation practices, including lack of contextualization, limited strategic focus, and insufficient integration with appropriate technologies and substantial government policies. To address these gaps, a manufacturing operation tree diagram is proposed, incorporating manufacturing operation considerations as organizational structure. This diagram aims to guide future research toward more realistic, validated, and industry-relevant simulation models in manufacturing operational research. By aligning simulation techniques with strategic manufacturing norms, the study contributes to the development of agile, resilient, and data-driven supply chains. The findings offer valuable insights for both academics and practitioners seeking to enhance supply chain performance through simulation-driven analysis and planning.
