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.
