Evaluation of the Efficiency of Maritime Transport Using a Network Slacks-Based Measure (SBM) Approach: A Case Study on the Korean Coastal Ferry Market

Safety is a key performance indicator for the sustainable management of coastal ferry service business. An efficiency strategy that balances safety and transport should be considered. The purpose this study to evaluate relative operators through undesirable safety-related output. Coastal create added value logistics activities such as cargo passenger transport. Accordingly, designed three-stage network-slacks-based measure (SBM) model delineated production services generation, execution, creation. Detention records marine accidents caused by human errors or technical faults were considered outputs. Moreover, 23 Korean firms have continuously managed business from 2015 2018 was analyzed. results showed differentiation improved when applying network SBM compared did not consider internal stage. This fact suggests it more desirable apply proposed in stringent comparison needed terms quality.
