An Empirical Survey on Co-simulation: Promising Standards, Challenges and Research Needs
Co-simulation is a promising approach for the modelling and simulation of
complex systems, that makes use of mature simulation tools in the respective
domains. It has been applied in wildly different domains, oftentimes without a
comprehensive study of the impact to the simulation results. As a consequence,
over the recent years, researchers have set out to understand the essential
challenges arising from the application of this technique. This paper
complements the existing surveys in that the social and empirical aspects were
addressed. More than 50 experts participated in a two-stage Delphi study to
determine current challenges, research needs and promising standards and tools.
Furthermore, an analysis of the strengths, weakness, opportunities and threats
of co-simulation utilizing the analytic hierarchy process resulting in a
SWOT-AHP analysis is presented. The empirical results of this study show that
experts consider the FMI standard to be the most promising standard for
continuous time, discrete event and hybrid co-simulation. The results of the
SWOT-AHP analysis indicate that factors related to strengths and opportunities
predominate
Holistic simulation for integrated vehicle design
A holistic vehicle simulation capability is necessary for front-loading component, subsystem, and controller design, for the early detection of component and subsystem design flaws, as well as for the model-based calibration of powertrain control modules. The current document explores the concept of holistic vehicle simulation by means of reviewing the current trends automotive system design and available solutions in terms of model interfaces and neutral modelling environments. The review is followed by the presentation of a Simulink-based Multi- disciplinary Modelling Environment (MME) developed by the authors to accommodate simulation work across the vehicle development cycle
