Problem $4_{?}$

The following diagram shows a production system with $5$ workstations as shown in the diagram below. Station A has two machines working in parallel. That is$,$ before proceeding to station B$,$ the product can be processed in either one of the two machines in Station A$.$ sequence along with their capacities, the number of units each can produce per hour.

a$.$ Determine the capacity $($in units per hour$)$ of the five workstations.

b$.$ Which workstation among the four is the bottleneck?

c$.$ If the production system operates $8$ hours per day, what is its daily capacity?

d$.$ If you could increase the capacity of any of the five workstations, which one would you focus on$?$ By how much would you increase the capacity $($or decrease the processing time per unit$)$ of this workstation? What would be the daily capacity of the entire system after these improvements were made?
