DEXi.NET: Open-source DEXi .NET Library in C#

Version 2.0

Purpose

DEXiNET20.zip contains an open-source library of C# classes that implement the evaluation of decision alternatives based on qualitative multi-attribute models produced by DEXi software.

DEXi.NET was ported from the JDEXi java library, version 4.0. DEXi.NET supports all non-deprecated functions of JDEXi4.

DEXiEval.exe

A console application for the evaluation of decision alternatives. It takes 2 mandatory parameters:

DEXi_file_name: file containing a DEXi model (.dxi)
Variables: a ";"-separated list of name=value pairs

Example


DEXiEval.exe Car.dxi "BUY.PRICE=low;MAINT.PRICE=low;#PERS=more;#DOORS=more;LUGGAGE=big;SAFETY=high"

TestDEXi.exe

Loads a DEXi model, displays some of its elements (attributes, value scales, decision rules, complex decision rules) and evaluates a random decision alternative.


TestDEXi.exe Car.dxi

DEXRuleAlgorithm.exe

Loads a DEXi model, displays complex decision rules for a specific aggregated attribute and elapsed time taken to generate complex decision rules.


DEXRuleAlgorithm.exe ../dxi/Car.dxi 0 time

jRuleAlgorithm.exe

Loads a DEXi model, displays complex decision rules for a specific aggregated attribute and elapsed time taken to generate complex decision rules.


jRuleAlgorithm.exe ../dxi/Car.dxi 0 time
