Framework for an interactive project scheduling system under limited resources

A framework is proposed for an interactive project scheduling system under limited resources. The framework includes a modelling module (MODEL) and a scheduling module (SCHEDULER). The modelling module MODEL allows the Decision Maker (DM) to develop his/her own model. The SCHEDULER is developed on a constraint-based scheduling algorithm. An important feature of the system is that the project plan can be updated by performing the least modification of future commitments. It is possible to freeze the activities already scheduled in the near future while admitting the changes in the activity/network information.
