Conference paper


This paper presents some concepts on how to plan, manage and automate tasks and activities with specific characteristics by describing these tasks in terms of fuzzy logic, transforming these descriptions into Prolog clauses and scheduling the tasks with a méta interpreter.

Fuzzy Phone is a tool which applies the mentioned concept to the field of telephone call management. It integrates in a graphical user interface the specification of telephone calls, the core system for scheduling calls to be instantiated and an operational component for the automatic realization of telephone connections. We focus in this paper on the second item, the core system for scheduling.

FuzzyPhone is based on the fuzzy concept theory founded by ZADEH in the mid-sixties and uses processing mechanisms, often denoted as fuzzy logic [1].
