solve a, b, c problems. please check units/hour, not units/min

3. (15 pts) There is a process using 4 resources: A, B, C, and D. The process flow diagram is below. a. What is the bottleneck of the process, and what is the process capacity? b. What is the cycle time of the process? c. What is the flow time of the process? Assume that flow units spend zero time in buffers. 3. (15 pts) There is a process using 4 resources: A, B, C, and D.
