Towards computer-aided multiscale modelling: An overarching methodology and support of conceptual modelling

Towards computer-aided multiscale modelling: A generic supporting environment for model realization and execution

“…Compared to a single-scale model, multiscale model is usually much more difficult to construct due to a range of conceptual, numerical and software implementation challenges (Yang and Zhao, 2009;Zhao et al, 2012). A number of efforts have been made to address these challenges.…”

“…In an ongoing effort which explores the feasibility of developing generic tools for Computer-Aided Multiscale Modelling (CAMM), a methodology has been proposed (Yang and Zhao, 2009;Zhao et al, 2012). This methodology applies a three-stage strategy by which computer based support of various degrees of "automation" is offered to conceptual modelling, model realization, and model execution.…”

“…This methodology applies a three-stage strategy by which computer based support of various degrees of "automation" is offered to conceptual modelling, model realization, and model execution. Following this methodology, a conceptual modelling tool has been prototyped (Zhao et al, 2012). Termed a conceptual model, the output of the tool is a specification of what scales are involved, how each scale should be modelled (in terms of components, phenomena, properties, laws and connections among components), and how different scales are connected.…”

On the Common Conceptual and Computational Frameworks for Multiscale Modeling

“…4 some minor extension introduced more recently by Zhao et al 26 The conceptualisation defines a set of concepts at the system, component, scale, and inter-scale levels; the key concepts are shown in Figure 1 by a UML class diagram 30 ; the exact definitions of these concepts can be found in Yang and Marquardt 25 . Briefly, a system is viewed to consist of components which are either subsystems or atomic components (called A A system generally has multiple states described via state functions which are classified into coupling-induced ones (i.e.…”

“…Zhao et al 26 The above conceptual framework is intended to provide a common basis for understanding and developing various multiscale models. A different framework has been proposed by Hoekstra and coworkers 22 based on cellular automata.…”
