Analysis techniques for dependability - Reliability block diagram and boolean methods
This International Standard describes procedures for modelling the dependability of a system*and for using the model in order to calculate reliability and availability measures.*The RBD modelling technique is intended to be applied primarily to systems without repair*and where the order in which failures occur does not matter. For systems where the order of*failures is to be taken into account or where repairs are to be carried out, other modelling*techniques, such as Markov analysis, are more suitable.*It should be noted that although the word repair is frequently used in this standard, the word*restore is equally applicable. Note also that the words item and block are used*extensively throughout this standard: in most instances interchangeably.
