Decision Support in a Telecommunications Engineering E-Learning Platform

This contribution presents the development of a decision support system to be used by telecommunications engineering students in selecting a suitable frequency filter design tool. System design follows the expert system paradigm and implements multi-criteria decision modelling using the Decision Matrix method, and combines set theory based option filtering with the MAUT method for option ranking. The expert system inference engine is rule based, while the knowledge base is designed as a Decision Matrix and implemented in a relational database. The user interface is to offer two types of user experience for beginners and advanced users. The system is developed as an integrated part of a telecommunications engineering online learning system, and is designed to be open-ended to incorporate additional filter design tools and decision criteria.
