Application of Multi-attribute Decision-Making to Determine the Preferred Strategy in Reducing the Casualty Risk Involving Indonesia's Domestic Ferries and RoRo Passenger Operation

Domestic RoRo passenger ferry transport can be considered a sensitive transportation mode. The sensitivity of operation is due to the significant role of service as the primary logistic distribution path connecting the islands within the Indonesian region. Based on existing accident data, it is unfortunate that domestic ferry transportation consistently faces accidents of a severe nature. From 2014 until 2022, nearly every year has witnessed accidents resulting in the loss of one or more RoRo and ferry vessels or rendering them inoperable. This study employs ELECTRE, a MADM method, to determine the most preferable strategies for preventing casualties. The criteria and strategy scores are weighed in these methods by collecting survey-based opinions from the relevant respondents. From the analysis conducted through the method, the strategy involving a change in field operation patterns and enhanced supervision in operational field patterns emerges as the primary strategy requiring significant attention for implementation. This mitigation effort concerns reducing the casualties involving domestic RoRo passengers in Indonesia.
