Procedures for the assurance of reliability of engineering decisions based on computed information are discussed. Reliability is assured when the mathematical model and the goals of computation are properly formulated and both the modelling and discretization errors are within acceptable tolerances. Both types of errors are controlled through systematic processes involving hierarchic families of models and discretizations.
