Basic Concepts into Methodologies on Systems Approach to Building Fire Safety

抄録

Methodologies on systems approach might be useful for the synthetic estimation of building fire safety. However, the meaning of their formula often seems obscure or irrational. This paper has a discussion on the characteristics of systems-structures applied to each method. For example, Gretener's method is basically composed by a divisional formula, which belongs to an emphatic expression with the ratio of hazard potential to safety countermeasures. The other discussions are on the point-making methods determining an effectiveness of fire facilities, with a tentative result of double effectiveness of sprinkler systems to heat detector equipments.
