Hybrid Modelling and Simulation (M&S): Driving Innovation in the Theory and Practice of M&S

Abstract

This is the author accepted manuscript. The final version is available from IEEE via the DOI in this recordHybrid Simulation (HS) is the application of two or more simulation techniques (e.g., ABS, DES, SD) in a single M&S study. Distinct from HS, Hybrid Modelling (HM) is defined as the combined application of simulation approaches (including HS) with methods and techniques from the broader OR/MS literature and also across disciplines. In this paper, we expand on the unified conceptual representation and classification of hybrid M&S, which includes both HS (Model Types A-C), hybrid OR/MS models (D, D.1) and crossdisciplinary hybrid models (Type E), and assess their innovation potential. We argue that model types associated with HM (D, D.1, E), with its focus on OR/MS and cross-disciplinary research, are particularly well-placed in driving innovation in the theory and practice of M&S. Application of these innovative HM methodologies will lead to innovation in the application space as new approaches in stakeholder engagement, conceptual modelling, system representation, V&V, experimentation, etc. are identified
