DEXi HTML Evaluator:
Running DEXi models in Web browsers

Version 1.0

Purpose

DEXi HTML Evaluator is a software package for using DEXi models in web browsers. Once a qualitative multi-attribute model has been developed with the DEXi software, it can be exported and included in a dynamic HTML document. When viewed by any common web browser, the document allows the user to enter and evaluate a single option (decision alternative) at a time. Supported are several modes of data entry (select boxes, radio buttons, check buttons) and treatments of unknown/uncertain/multiple input values.

The dynamic HTML document is strictly client-side. Apart from loading the necessary JavaScript libraries (jQuery.js and DEXi.js), all processing is carried out locally and does not involve any servers.

Example

Demo DEXi model for the evaluation of cars, normally distributed with the DEXi software.

Components

The DEXi HTML Evaluator software package DEXiHTML10.zip consists of:

• DEXiHTML.html: HTML document template.
• DEXi.js: JavaScript library implementing DEXi evaluation and HTML user interface.
• DEXi.css: Stylesheet for the HTML document.
• Car.js: Demo Car Evaluation DEXi model in JavaScript format.
• Readme.html: Basic description of the package (this document).

Usage

To set up your own DEXi HTML Evaluator document, proceed as follows:

1. Develop your own model in DEXi software. DEXi version 5.02 or later is required.
2. From DEXi, save it (File/Save as...), requesting the JavaScript format, to a file, say, MyModel.js.
3. From DEXiHTML10.zip extract the template document DEXiHTML.html and rename it to MyModel.html.
4. Edit MyModel.html using your text editor. Where indicated, change "[some path...]Car.js" to "MyModel.js" (and add your path, if necessary).
5. Open MyModel.html in your browser. It should work instantly.
