Abstract
Purpose: This study aims to develop a performance evaluation model tailored for Malaysian ports that addresses the limitations of existing global frameworks. While ports are crucial to trade and economic growth, their operations pose environmental challenges, including emissions, pollution, and habitat loss. Sustainable port initiatives are increasingly adopted to address these concerns, but existing performance measurement models often require extensive data and are not suited for localized application. This study seeks to provide a simplified, initiative-based model to assess sustainability performance efficiently and effectively within the Malaysian context. Design/methodology/approach: A Mixed Integer Linear Programming (MILP) model was formulated to assess port sustainability based on actual initiatives documented in annual reports from several major ports in Malaysia for over two years. Thematic analysis was used to categorize the initiatives into sub-factors under four core functions: landlord, regulatory, operator, and community. The MILP model incorporated an iterative optimization process involving four weightage scenarios and 100 iterations each, to determine the optimal configuration that maximized the sustainability score (Z), ensuring statistical robustness and relevance to operational realities. Findings: The Operator Function (OF) contributed most significantly to sustainability performance (Z₃ = 1.126), followed by the Landlord Function (Z₁ = 0.487), Regulato
