Towards Continuous Simulation Credibility Assessment

Abstract

With the growing demand for virtual-informed decision-making in the development process of many engineering domains, the evidence in simulation results and thus simulation credibility becomes a critical aspect, in particular for releasing safety-relevant systems. However, simulation credibility is often interpreted to be of subjective nature. This paper summarizes basic assumptions for enabling the expression of credibility for building evidence in a more objective way. Based on these considerations, a concept is proposed that allows for an approximation of the credibility of simulations according to a discrete scale. The work is concluded by providing an implementation concept for a continuous simulation credibility assessment using a layered standard on top of the System Structure & Parameterization specification.

Modeling & Simulation SPICE: Assessing the Capability of Credible Simulation Processes

“…This applies in the same way to the credibility, process capability and artifact quality levels to be achieved. As this paper and thus the following chapters only cover the process capability assessment in the context of the UPSIM CAF, i.e., M&S SPICE, at this point, we would like to refer to the recently published paper by Ahmann et al (2022), which in the same context addresses the dimension of artifact quality with the associated quality assurance methods.…”
