ABSTRACT

The Expert Scheduling Advisor (ESA) is a prototype included in the ESPRIT Project 2189. ESA aims at minimizing the supplementary costs due to irregular use of resources.

A first prototype of the Expert System was written in May 1990, based on user’s first specifications. These main specifications are:

– set of activities which are connected with Finish-Start (FS) relations; – each activity has a duration in days, and uses per day a certain amount of resources; – the schedule scheme has a required length L in days; – the aim was to smooth the consumption of each resource, or to approach to the average

consumption as much as possible.
