Abstract
Up to this time, system safety was required with an abstract presentation as “no hazard or should be safety”, but it now can not maintain the safety unless to be made sufficient preparation and counter-measure since present systems become increasingly complicated.
Further, now system safety is required with the quantitative presentation as so as reliability and maintainability etc., and must be managed as holding the safety of not only hardware but the associated personnel through operation from production at system design period.
This paper describes prediction and analysis for system safety design that should be done with step by step in order to achieve the design of system safety, and the outline of some of those techniques.
