Seaport inefficiencies have caused barriers to maritime operations especially operational disruption which ultimately adds to high-cost expenses, redundant waste, environmental pollution, and financial losses. As a result, trade and environmental sustainability cannot be attained which will impact the complete maritime supply chain-related aspects. Therefore, a Lean, Agile, Resilience, and Green (LARG) performance model is proposed as a method to control these issues and improve the competitiveness and efficiency of seaports in the Indian marine context. LARG criteria in the seaport supply chain have been identified and analyzed using extensive literature reviews and expert assessments based on the Indian maritime perspective. This paper aims to identify and select the relative importance of each LARG performance model on basis of operational, economical, and environmental related performance of seaport supply chain using the Analytical Hierarchy Process (AHP) technique by forty-three experts from various maritime domain experts in India. The research results indicate that operational performance has the highest contribution to seaport supply chain performance in Indian seaports followed by economical and environmental performance. This research study can also assist on related dimensions in port performance and its efficiency, to enhance trade capabilities, operational efficiencies, and competitive advantages of the seaports in the maritime supply chain area. Furthermore, this LARG management tool can be applied in the global maritime context considering adaptability aspects.
