This webinar is being held as p​art of the ASSESS Credibility Theme

Recently, there has been a significant increase in the demand for the systematic integration of Modeling and Simulation (M&S) in product development methods, product release and design standards, and product release processes. Furthermore, M&S now plays a pivotal role in driving virtualization. With this growing reliance on M&S in engineering design decisions, the credibility of M&S is gaining increased importance.
In this webinar, we present the Robert Bosch (RB) credibility of simulation framework. The framework is designed to establish a common understanding across diverse domains and products, providing a unified generic approach. We describe the phases of the framework, covering engineering task description, defining the decision consequence, M&S risk assessment, credibility assessment, and making simulation-informed engineering decisions.
For M&S risk and credibility assessment, we highlight our Verification, Validation and Uncertainty Quantification (VVUQ) activities encapsulated in a “Credibility Wheel,” which now integrates M&S risk assessment into the overall credibility assessment.

Experience gained from applying the framework has underscored the need for tailored credibility assessment methods suitable for different domains. Thus, we present examples of tailored credibility assessment methods for specific domains such as (Finite Element Method (FEM) and Software-in-the-Loop (SiL)).

Furthermore, the webinar shows that this framework is consistent with x-company approaches for Simulation Credibility Assessment. Achieving credibility relies not only on internal efforts but also on collaboration with external models and tool providers. The webinar presents the white paper “Simulation Credibility Assessment,” which is a joint publication by the SmartSE – Smart Systems Engineering project group authored by Robert Bosch GmbH, ZF and UNITY as consortium partners of the SmartSE project group. In the paper we investigated practical methodological approaches for determining and evaluating the simulation credibility of numerical simulations to be performed in the context of cross-company, model- and simulation-based development, as already used today in the automotive industry. The approaches are very generic and not automotive specific according to the x-industry partners of SmartSE project group.

The approach defines clear, practice-oriented minimum requirements for the quality and validation of simulations with the M&S Credibility Levels (M&S CL 1–4) according to the Purpose of Simulation:

• “Trend Behavior” (M&S CL1): Design support by relative comparisons or early concept evaluation. Not applicable for product V&V.
• “Quantitative Predictions” (M&S CL2): Design support by quantitative predictions, prepare physical product V&V.
• “Design Evaluation” (M&S CL3): “Design Evaluation” By reliable quantitative predictions with reduced number of physical tests.
• “Virtual Product Verification & Validation” (M&S CL4): “Virtual Product Verification & Validation” - Without additional physical test of corresponding requirements.

The “M&S Credibility Level” serves as a comprehensible, qualitative evaluation criterion and link between product managers and decision-makers on the one hand and simulation engineers on the other hand. This approach thus lays the foundation for modern, fully virtual, and efficient product development by creating the necessary basis of credibility for the widespread use of numerical simulations in decision-making and approval processes. Additionally, an equivalent credibility assessment is defined for each “M&S Credibility Level” to give an orientation to the end-user about the VV&UQ activities to be performed for each level.

In conclusion, the work outlines the challenges faced in establishing the credibility of the simulation framework and incorporating it within Bosch, a company with a diverse application domain scope.
