Use the project information in the table to resolve resource conflicts,identify the critical chain and critical path,and create feeder buffers.A feeder buffer should be placed immediately before: $$\begin{array} { | l | l | l | l | l | l | l | l | }
\hline \text { Activity } & \text { Predecessor } & \text { Length } & \text { Resource } & \text { Activity } & \text { Predecessor } & \text { Length } \text { Resource } \

To resolve resource conflicts, we need to analyze the resource requirements for each activity and ensure that resources are available when needed. Activity A and D both require resource P, which means they cannot be worked on simultaneously. However, activity B can be scheduled before activity D, which would free up resource P and allow it to be used for activity A. 
The critical path for this project is A-B-C-F, with a total length of 26 days. The critical chain, which takes into account resource constraints, is A-B-D-E-F, with a total length of 36 days. 
To create feeder buffers, we need to determine the duration of each non-critical activity and add half of that duration as a buffer before the activity. The non-critical activities are B, C, and E. 
Therefore, a feeder buffer should be placed immediately before activity F (the end of the critical path) and immediately before activity B (the beginning of a non-critical path). Since activity B has a shorter duration, it will have a smaller feeder buffer, but activity F will have a larger feeder buffer. 
Overall, the best choice for placing a feeder buffer is B, as it is the beginning of a non-critical path and has the second-longest duration of the three non-critical activities.
