Building Modeling Tools That Support Verification, Validation, and Testing for the Domain Expert

Abstract

Successfully building a model requires a combination of expertise in the problem domain and in the practice of modeling and simulation (M&S). Model verification, validation, and testing (VV&T) are essential to the consistent production of models that are useful and correct. There are significant communities of domain experts that build and use models without employing dedicated modeling specialists. Current modeling tools relatively underserve these communities, particularly in the area of model testing and evaluation. This paper describes several techniques that modeling tools can use to support the domain expert in performing VV&T, and discusses the advantages and disadvantages of this approach to modeling.

An approach for the systematic development of domain‐specific languages

“…Others examples that independently confirm our results are based on the idea to build DSLs from component building blocks that can be incrementally designed and composed [1,41,51,68,70]. This idea originates from approaches such as keyword-based programming [8], in which so called "keywords" serve as building blocks for DSLs.…”

“…Therefore, we do not explicitly address the grammarware view on DSLs, even if some of our findings may also be applicable to this field of research as well. Figure 1 depicts the main DSL artifacts and their relations 1 . From a language user's point of view, the DSL consists of language elements.…”

Design verification and validation in product lifecycle

“…Verification and validation have been defined in various ways that do not necessarily comply with standard definitions. For instance, journal articles and textbooks use the terms ''verification'' and ''validation'' interchangeably [7,8], or in some cases there is reference to ''verification, validation, and testing (VV&T)'' as if it were a single concept, with no discernible distinction among the three terms [9]. Table 1 shows definitions of verification and validation as provided by international and national bodies.…”

A framework for concept validation in product design using digital prototyping

“…Various studies such as [1,[6][7][8] have tried to involve customers in conceptual design. The results of these studies show that involving customers in conceptual design can increase the chance to generate and find better product concept(s).…”
