Qualitative Simulation - Kuipers (2001)   (97 citations)  (Correct)

....well de ned interfaces. Electrical circuits and uid ow systems are obvious physical domains where component connection models are often appropriate, but the same framework can be useful in more abstract settings such as compartmental modeling in biology [16] and system dynamics in economics [14]. Qualitative Simulation DRAFT: February 26, 2001 19 A component is a subset of a system, described by variables and constraints, that interacts with other portions of the system only through variables associated with explicitly speci ed terminals. A connection is an explicitly speci ed identity ....

A Multimodeling Basis for Across-Trophic-Level Ecosystem .. - Fishwick, Sanderson, al. (1997)   (1 citation)  (Correct)

....model as an abstract often visual formal representation of a system. It is formal in the sense that the representation is provided with a level of clarity that affords execution of the representation on a computer. Examples of model types are: finite state machines, System Dynamics models (Forrester 1969; Forrester 1971; Richardson and Pugh 1981) Petri nets (Peterson 1981) Bond Graphs (Thoma 1975; Cellier 1991; Rosenberg and Karnopp 1983) and sets of ordinary or partial differential equations. A drawing that is informal might exhibit the facade of a model, but if it does not conform to strict ....

Using Adaptive Agent-Based Simulation Models to Assist Planners.. - Bernard (1999)   (Correct)

....email: minusone alumni.princeton.edu website: http: www.walrus.com minusone Abstract: 2 Computer simulation modeling for policy development in planning has had difficulty gaining a consistent foothold. Reasons for this include bad experiences with large scale, comprehensive models (e.g. Forrester, 1969) and the lack of theory that one can quantify (Batty, 1994) Batty (1994) has suggested that new types of computational models, based on the tenets of complexity theory (Bernard, under revision) may prove useful. One type of complexity theory model is an adaptive agent based model in which the ....

....of one of these scenarios. Even more useful would be the ability to dynamically change policy midstream when the simulation is in the process of running. Such policy simulation would be useful for any number of purposes. This idea is not new, of course. In a highly influential book, Forrester (1969) tried many different types of policy simulation using his Urban Dynamics model. This model simulated a highly abstract (and spatially undifferentiated) fictional city. Forrester did not calibrate this model will any real data instead he simulated the city s development starting from an empty ....

An Integrated Approach to System Modelling using a Synthesis of.. - Fishwick (1992)   (1 citation)  (Correct)

....in formalization, model engineering is a critical task and should be a central activity within the simulation field; we want to better understand the very nature of modelling including how and why we choose the models that we do during the course of systems analysis. The area of Systems Dynamics [42, 41, 74, 75] focuses, not only on the formalism for a dynamic model but also, on several key steps during the model building process: 1) causal model without signed information, 2) causal model with signed arcs and loops, 3) flow graph, and finally 4) equations (or program) These steps provide clues as to ....
