Economic Models

In order to prove the concept that User Driven Modelling is applicable to domains outside engineering, I'm developing economic models using the same kind of translation technique as I used for engineering models. Models are created in the Vanguard System (http://www.vanguardsw.com/) modelling tool, and can be imported to this from Protégé http://protege.stanford.edu/, via nested SQL queries. Vanguard System performs the calculations necessary for the economic model.

The next step is to visualise the Models in the web browser, and in various languages, to show the concept of multiple language implementations being created from one model. These multiple language implementations all share the same semantics and provide a tree based representation of this semantics.

These are demonstrated at http://www.cems.uwe.ac.uk/~phale/EconomicModels/ModelsVisualised.htm, different representations are provides, so that hopefully at least one representation is accessible to the various web browsers. So far there is an XML, HTML, and Java Applet representation. My intention is to extend both the representation of models and the number and type of models represented, until there is a large grid of models, and representations. Options for extending the representation are to JavaScript, SVG, RSS, RDF, and meta programs, and to increase, the interactivity/editability of the models.

This technique should allow automated creation of many models and language representations of them automatically, using one set of model code outputters/translators.

I'm getting the economic models from Biz/ed - http://www.bized.co.uk/educators/he/spreadsheet/section_1.htm. Eventually I might extend this to other types of models as well as engineering and economic models.

The implementation of the models is at http://www.cems.uwe.ac.uk/~phale/EconomicModels/ModelsVisualised.htm.
