A Sequential-Logical Chart Method for Safety Elements in a Fuze Safety System

Based on the theory of fare safety systems,the paper studies the interrelations and shared properties among the safety elements making up a fare safety system and presents a generalized S-L chart method for the analysis and identification of the sequential and logical relationship of the safety elements.It finally gives two important inferences.The result shows that the S-L chart can provide an effective means for the study of safety elements in a fuze safety system and their interactions.
