Multi Criteria Decision on Selecting Optimal Ship Accident Rate for Port Risk Mitigation

Large ports have potential catastrophic accidents by handling enormous amount of hazardous and dangerous materials which tend to increase the risk of port and the facilities in its vicinity. In the paper, we propose a mathematical method to identify the ship accident types affecting risk in port areas which propagate into death of people as a consequence of the accidents. We consider a multi criteria port risk problem and a goal programming modeling is constructed for calculating accident rates of each accident type. The obtained results can be employed by decision makers or port authorities in implementing the port risk mitigation measures or in designing (planning) future port construction.For the study, we use the accident data for the 12 domestic ports over the last 5 years from 2002 to 2007.
