Gemilerde insan güvenilirliği analizi üzerine bir karar verme model önerisi

The purpose of this thesis is to develop an unique human reliability analysis approach on-board ship based on a decision-making model proposal in order to eliminate and minimize the human error during critical shipboard operations. This approach, additionally contributing current human reliability analysis methods in academic literature, will be applicable on vessel fleets such as container, chemical tanker, petrol tanker, LGP tanker, bulk. With the study under this thesis, it is predicted to reach solid targets mentioned below: i) To minimize the error risk by assessing human reliability in shipboard operations, ii) To test proposed approach for critical shipboard operations such as loading or discharging cargo, bunkering, ballast operations, anchoring, shipboard contingency actions, working in enclosed space, maritime pollution prevention, iii) To create available solutions for shipboard operational concept by developing a valid approach to human error assessment, iv) To determine preventive actions (that improves human reliability) against pivotal factors that cause errors in shipboard operations, vi) To contribute to ship safety management system practices. In human reliability analysis study of correlation among variables especially with incident causalities generic task types (GTT) and error producing conditions (EPC), suitable customization to ship platform, weighting of variables related to decision-making method, consistency in weighting and increasing sensitivity can be mentioned as original aspects of the project. In other words, EPC values will be re-determined by quantifying variables of an existing human reliability analysis method (HEART) with synthesis of human factor analyse and classification system (HFACS) approach. Also, this thesis proposes a smart solution utilising analytic hierarchy process (AHP) technique to weight the importance of each EPC since they are weighted from 0 to 1.Because term descriptions of variables of existing studies in literature are in general structure and direct weighting is implemented on variables. With this study, via offering solutions to related points, implementation of management of human error analysis and reduction technique will be consistently provided in maritime industry. Specially, even though there are peculiar, developed human reliability analysis methods in aviation and railway as well as nuclear industries, there is no unique method for maritime industry yet. With the method presented by the thesis will both satisfy this requirement and it is expected to be utilized in similar sectors such as ports, shipyards, off-shore platforms, etc. To keep contact with academic and industrial experts to contribute researchers` careers. As a result, proposed thesis with these aspects, will be providing new perspective to human reliability assessment researches and will provide marine-specific HRA in transportation industry.
