4. Schedules based on time-oriented networks
CPM & PERT Assumes unlimited resources
Activities Analysis based on Time Requirements
Projects resources demands VS limited quantities

5. Resource Scheduling Time- constrained scheduling
Manipulating the activities time within their TF.
Resource-constrained scheduling
Resource-constrained priority is fixed resource availability.

6. Optimizing resource-constrained scheduling
Solutions based on mathematical optimization
Short project duration & smoothest resource profile
Solutions based on Heuristics
Computer packages.

8. Proposed new resources scheduling algorithm
LINRES
Developed using Precedence & Grantt chart
Aim is optimized resource constraint & best (t)

9. Conclusion Resource-constraints is persisting problem
Software might speedup process of LINRES
The LINRES algorithm is satisfactory
Further investigation is needed
