The target of acceptance : Towards a precise definition of the intended purpose
conference paper
With the goal to objectively demonstrate the fitness for purpose of a simulation model during its valida-tion, the desire arises to remove vagueness from the terms “fitness” and “purpose”. Several approaches have been presented in the past trying to facilitate and motivate the documentation of "well-defined intended purposes", but still in defense practice a precise purpose specification for a simulation model is rare. Within the methodology developed under the umbrella of WEAG THALES JP11.20 “REVVA”, the concept of the “Target of Acceptance” (ToA) was in-troduced, enabling clear traceableness between the vague intended purpose and precise, quite objectively assessable acceptability criteria.
Based on the notion of the Experimental Frame, this paper extends the approach taken in REVVA and proposes a method how to hierarchically derive from the intended purpose a number of sub-objectives of model use, until repre-sentative sets of experimental conditions can be defined, under which the simulation model needs to be valid. Analysis of the sensitivity of the contextual objectives to the simulation goal parameters yields an indication for their acceptable imprecision (and thus their acceptable inaccuracy), which can be formulated as testable acceptability criterion.
