Hello Sir,
Question :
A manufacturing company uses three processes to make its two products, X and Y. The time available on
the three processes is reduced because of the need for preventative maintenance and rest breaks.
The table below details the process times per product and daily time available:
Hours required Hours required
Hours available to make one unit to make one unit
Process per day of product X of product Y
1 22 1.00 0.75
2 22 0.75 1.00
3 18 1.00 0.50
Daily demand for product X and product Y is 10 units and 16 units respectively.
Which of the following will improve throughput?
? Increasing the efficiency of the maintenance routine for Process 2
? Increasing the demand for both products
? Reducing the time taken for rest breaks on Process 3
? Reducing the time product X requires for Process 1
Sir, isnt process 3 the bottleneck over here ? I dont understand how did they get process 2 over it ?

To meet the full demand, Process 1 would need (10 x 1) + (16 x 0.75) = 22 hours, and so there are sufficient hours.
Process 3 would need (10 x 1) + (16 x 0.5) = 18 hours, and so there are sufficient hours.
Process 2 would need (10 x 0.75) + (16 x 1) = 23.5 hours. There are only 22 hours available and so it is Process 2 that is limiting the production and is therefore the bottleneck.
