Ultimate limit state-based multi-objective optimum design technology for hull structural scantlings of merchant cargo ships

PERFORMANCE-BASED MULTI-OBJECTIVE OPTIMUM DESIGN FOR STEEL STRUCTURES WITH INTELLIGENCE ALGORITHMS

A multi-objective heuristic particle swarm optimiser (MOHPSO) based on Pareto multi-objective theory is proposed to solve multi-objective optimality problems. The optimality objectives are the roof displacement and structure weight. Two types of structure are analysed in this paper, a truss structure and a framework structure. Performance-based seismic analysis, such as classical and modal push...

Design Aspects of Survivability of Surface Naval and Merchant Ships

The paper addresses various design aspects of survivability for surface naval and merchant ships through a common rational probabilistic methodology. It is based on earlier work of Kurt Wendel on a probabilistic approach to the damage stability of surface ships. This method was adopted by SOLAS 1974 through Res. A.265 (VIII) as an alternative to the deterministic SOLAS criteria for passenger sh...

Occupational accidents aboard merchant ships.

OBJECTIVES To investigate the frequency, circumstances, and causes of occupational accidents aboard merchant ships in international trade, and to identify risk factors for the occurrence of occupational accidents as well as dangerous working situations where possible preventive measures may be initiated. METHODS The study is a historical follow up on occupational accidents among crew aboard D...

Optimum Design of Pultrusion Process via Evolutionary Multi-objective Optimization

Pultrusion is one of the most cost-effective manufacturing techniques for producing fiber reinforced composites with constant cross sectional profiles. This obviously makes it more attractive for both researchers and practitioners to investigate the optimum process parameters, i.e. pulling speed, power and dimensions of the heating platens, length and width of the heating die, design of the res...
