Resumen de Enhancing safety of helicopter maritime operations: Fuzzy modeling approach
Helicopter operations are a vital part of search and rescue (SAR) operations, transportation of personnel and materials in offshore and military operations, etc. which is an important part of maritime system. Characteristics of safety procedures, crew capabilities and helicopter performance have important effects on the aviation safety management system (SMS). Aviation safety assessment based on conventional methods (e.g. probability risk assessment) may not be well suited for dealing with maritime systems having a high level of uncertainty. Nowadays, about ten percent of maritime accidents are caused by human related activities. Defining and evaluating the effecting factors could be a base for risk mitigation and/or reduction strategies development. This paper details possible caused factors related to human factor, helicopter type, weather conditions, heliport lighting and other surface conditions, etc. A fuzzy logic approach may be more appropriately used to carry out risk analysis in the initial design stages by providing proactive measures for reducing risks. Defined factors were modeled by the fuzzy logic approximation in order to develop a computer program for the risk assessment in helicopter maritime operations. Obtained results present efficient and practical methodology to assess factors related to humans and aviation organizations.
