Modeling of Decision-Making Process Relating to Design of Ship Power Plants Safe for Operators

Abstract

This paper deals with a computer-aided system for design of ship power plants safe for their operators. The specificity of ship power plants allows to assert that all plant spaces can be more or less dangerous for operators carrying out any operational or maintenance tasks. For this reason, these plants should be well-designed to minimize the possible hazards for their operators. The proposed system of the hazard zone identification in the ship power plants is based on both their preliminary design and the expert subjective assessments enable to assess the potential risk for operators. It has been prepared a special questionnaire to collect this kind of subjective information. The acquired results have been used to build the risk assessment system with the fuzzy knowledge base.
