Selecting Suitable, Green Port Crane Equipment for International Commercial Ports

Responding to the increasing global need for environmental protection, a green port balances economic vibrancy with protection. However, because exhaust emissions (e.g., CO2 or sulfide) are difficult monitor around ports, data on such often incomplete, which hinders research this topic. The present study aimed fill gap in To remedy problem, formulated new envelopment analysis (DEA) method collecting at their source. This was applied collect real-world operating from large container-handling company Taiwan. Specifically, we provide real example using novel energy index account undesirable outputs. Our main objective formulate two methods that combine: (1) based modified slack-based measure, and (2) multi-choice goal programming approach. contributions of paper included finding rubber-tired gantry cranes greenest should be used ports. Finally, our findings aid managers selecting equipment provides best balance between protection profitability.
