P-Expert: Implementation and Deployment of Large Scale Fuzzy Expert Advisory System

Abstract

This paper discusses the problem of parthenium weed infestation in Queensland and describes P-Expert, an expert advisory system designed to provide expert knowledge in control and management strategies of parthenium weed. P–Expert is fundamentally a hybrid fuzzy expert system incorporating technologies from fuzzy logic, relational database and multimedia systems. The primary topic of this paper will be a description of the framework of P-Expert, focussing on three main areas: (1) Layered component architecture – each component of the expert advisory system is designed as modules to facilitate maintenance, adaptability and flexibility, (2) Discourse semantics (explanatory capabilities) – provision for explanation and justifying outputs given by the expert advisory system, (3) Metaconsequent – mapping final aggregated output from a fuzzy If–Then rule onto a finite database, and (4) Deployment of large scale advisory expert system.
