MATHEMATICAL MODEL OF MARINE FIRE-DANGEROUS SITUATION HAZARD RATE BASED ON FUZZY OUTPUT SYSTEM

The article describes development of mathematical model of marine fire‑dangerous situation hazard rate based on fuzzy output system. Stepwise process of fuzzy inference is described in detail, particularly: formation of rules base, input variables fuzzification, aggregation of sub‑conditions, activation of sub‑conclusions, accumulation of conclusions and defuzzification of the output variables. Algorithm of fuzzy marine fire safety database formation based on Mamdani algorithm is disclosed. Membership function type is chosen and substantiated. Developed model provides algorithmic support of security and viability marine systems with mathematical apparatus for decision making for the purpose of elimination of fire or effective fire‑extinguishing in case of rapid flame development. Integration of developed mathematical model inside ship information management systems’ algorithmic support is capable of dramatically raise effectiveness of decisions made while providing fire safety on ships.
