Abstract
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.
