Disruption management for resource-constrained project scheduling

G Zhu, J F Bard, G Yu
2005 Journal of the Operational Research Society  
In this paper, we study the problem of how to react when an ongoing project is disrupted. The focus is on the resourceconstrained project scheduling problem with finish-start precedence constraints.  ...  The problem is formulated as an integer linear program and solved with a hybrid mixed-inter programming/constraint programming procedure that exploits a number of special features in the constraints.  ...  Based on the propagation of the precedence constraints for branch 2, activity 5 with duration 3 will now have a finish time window of [18, 27] and activity 7 will have a finish time window of [21, 27  ...

Project Scheduling Approach to Production Planning

A. Márkus, J. Váncza, T. Kis, A. Kovács
2003 CIRP annals  
Orders are modelled as projects that compete for limited resources. The projects consist of networks of variable-intensity activities which may require several resources at the same time.  ...  Although the capacity and material flow aspects of PP are coupled, a special solver developed for the project model efficiently solves problems of real-life sizes.  ...  Then, the first two weeks' production plan was passed to a constraint-based finite job-shop scheduler that worked with a 0.1 hour time unit.  ...
