can someone please help me with b and c

4) [5 pts] A production process at OU Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the folding and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel). Assume that demand is very large. b) [2pts] Fill in the blank (do not forget your measurement unite) c) [1 pts] We assumed that demand is very large in this case, but now let's assume that demand is very small, say demand is 1 unit/hr. How would this affect bottleneck time and throughput time? Choose one out of three options (up, down, no change) for each sub-question below. a. Bottleneck time: b. Throughput time: UpUpDownDownNochangeNochange
