solve Q

The precedence view of the network diagram shows the tasks as they are scheduled using predecessor and successor relationships. These relationships are not leveled with regard to the utilization of resources; they are simply shown in sequential order. Tasks not connected together or joined by arrows can be performed in parallel.

• Resolve the resource contentions by creating a load leveled view that retains the task logic, but considers the capacity of the resource. No two tasks performed by the same resource should be scheduled at the same time.
• Subordinate merging paths with feeder buffers and exploit the project with a project buffer. Add resource buffers if needed. Use late start for project tasks.
• Identify the critical chain.
