Designing Lean Supply Chain Framework in the Offshore Sector of the Oil and Gas Industry with a Sustainable Development Approach

Today, Companies can use different supply chain paradigms to achieve better performance and improve their competitiveness. Lean supply chain is one of these paradigms that focuses on eliminating waste along the chain. On the other hand, the lean approach emphasizes three dimensions of economic, social and environmental along the chain and can lead to sustainability in supply chain. In fact, sustainability refers to a good balance between economic development, social assets and environmental issues. Due to the importance of the oil and gas industry in our country, the implementation of a lean supply chain based on sustainability in active organizations in this area is very important.

In order to conduct this study that has been carried out in one of the largest companies operating in the offshore sector, first, by reviewing the literature and opinion poll at the experts, the ten factors that lead to lean supply chain were identified. Then, using an interpretive structural modeling approach, the research framework was developed.

in this framework, "management and leadership" as the most influential and the two factors, "minimization of delivery time" and "flexibility" were determined as the most influential factors.

Accordingly, the "management and leadership” was the basis of this framework and should be much considered. Finally, some suggestions were made to achieve lean procurement process with sustainable approach in the offshore sector of the oil and gas industry.
