Abstract
Application of fuzzy inference to assessment of degree of hazard to ship power plant operator This paper presents application of fuzzy logic to assessment of degree of hazard to ship power plant operator. For the assessment a system of computer-aided identification of hazardous zone within ship power plant, was used. The system's variables representing the subject-matter knowledge in safety design area were transformed into fuzzy sets by means of appropriate linguistic variables and membership functions. The assessing of safety level of operator with the use of fuzzy inference was performed by means of an expert system programmed in the PROLOG LPA language.
Highlights
Complex technical objects can create significant hazards to safety of their operators
In the authors’ opinion it is possible provided use will be made of information on structure and function of a power plant, contained in preliminary design documentation, as well as its consideration will be limited only to the zones where an operator carrying out certain service operations concerning a given technical object, appears
This work is aimed at consideration of possible application of fuzzy logic to assessing hazardous zones to ship power plant operators
Summary
Complex technical objects (e.g. large transport units, electric power plants and power systems, chemical systems) can create significant hazards to safety of their operators. It would be advisable to indicate, just in early design stages, such places in a ship power plant, which create potential hazards to operators. The question appears whether it would be possible to limit consideration of ship power plant only to potentially most hazardous zones during designing its safety. In the authors’ opinion it is possible provided use will be made of information on structure and function of a power plant, contained in preliminary design documentation, as well as its consideration will be limited only to the zones where an operator (operators) carrying out certain service operations concerning a given technical object, appears. This work is aimed at consideration of possible application of fuzzy logic to assessing hazardous zones to ship power plant operators
