Multi-Attribute Decision-Making Ship Structural Design

This study develops a procedure for performing multi-attribute decision-making ship structural design of multi-purpose ship. The already designed is further structurally to comply with the requirements Classification Societies. hull and components are verified against yielding, buckling, ultimate strength. Based on limit state (ULS), first order reliability method (FORM) employed analyse risk in reducing probability failure. costs associated materials, manufacturing, labour estimated. analysis performed, accounting different hazard issues related loss ship, cargo, human life, accidental spill fuel oil. risk-based used identify an optimum level safety, i.e., index, controlling design. uses multiple attribute approach, simultaneously considering several objectives scenarios employing Technique Order Preference by Similarity Ideal Solution (TOPSIS). identified solution minimum expected total cost leading lower construction operational maximum cargo capacity energy efficiency. developed flexible enough accommodate criteria possible hazards during ship’s service life.
