Computational and Applied Mathematics, 2023 AbstractBroadly speaking, models are representations of something concrete or not. In science, models have always a purpose related to understanding and explaining phenomena. This requires focus and selecting what to represent and what not to represent and how to represent, among other things.

Decision Support Systems, 1993 Abstract While other work in model management has looked at models as static objects to be administered in database-like fashion, we emphasize the central role of process knowledge in model construction, usage, and maintenance. We claim that tools are needed to collaboratively elicit knowledge, to represent it conceptually, and to maintain its ...

Generalized velocity–density model based on microscopic traffic simulation
Transport, 2018 In case of the Intelligent Driver Model (IDM) the actual Velocity–Density law V(D) applied by this dynamic system is not defined, only the dynamic behaviour of the vehicles/drivers is determined.

Hillslope diffusion and channel steepness in landscape evolution models [PDF]
Earth Surface DynamicsThe streampower (SP) fluvial erosion model is the basis for many landscape evolution simulations and analyses. It assumes that river incision into bedrock depends only on flow intensity and rock erodibility and is insensitive to sediment flux.
