Abstract:

Creating a revised plan requires experience and significant time. To lessen the effort involved, a knowledge-based system named SCHEREC (SCHedule RECovery) was developed which suggests decisions which should be considered for schedule recovery actions. In order to yield a solution for delay recovery, SCHEREC may borrow resources from one activity (slowing down that activity) and lend them to another activity (speeding up this activity). Also, it suggest hiring new workers to speed up a given activity, or advises the user to put a certain trade on overtime for a period of time. It checks if the delay can be recovered, or if the cost of the changes in the schedule can be offset by any loss for not completing the project on time. SCHEREC helps meet contract time commitments and makes it easy to avoid ineffective actions.
