Marine transportation optimization for hazardous and noxious substances by implementing Fuzzy-AHP

Abstract

Carefully selected ship will be helpful to decrease fuel consumption at sea and minimize the companies’ variable costs. The selection process can be very complex, which requires a lot of calculation and qualified people on maritime business and can be highly time-consuming to determine all available ships during the comparison has been made. To solve this problem questionnaires have been answered by qualified 30 experts who are already experienced in marine-field. According to both literature and marine experts selected “safety of cargo”, “freight cost”, “duration of transportation”, “ease of transition to new cargo”, “maximum load-carrying capacity in a single voyage” criteria have been pair-wisely compared and ranked. Criteria ranking has resulted as C1 > C2 > C5 > C3 > C4 > C6 > C7. The ranked criteria names accordingly are “Safety of cargo” > “Freight cost”> “Maximum load-carrying capacity in a single voyage”> “Duration of transportation”> “Ease of transition to new cargo” > “Cargo handling duration” > “Transportation of different cargo together”. In further articles, it is believed that by adding the “frequency of voyage” and “total voyage length” criteria and comparing vessel types as alternatives may be very useful for literature.
