3 process that make 2 products X and Y. Hours available for the processes are 22, 22 and 18 respectively. Hours required by the processes to make one unit of X are 1, 0.75 and 1 respectively. To make one unit of Y the processes require 0.75, 1 and 0.5 hours respectively. Daily demand: X=10 units, Y=16.
The answer says the bottleneck is process 2 because it doesn’t have the capacity to meet demand. I don’t understand why.Making 10 units of X and 16 units of Y will take the following time in each process.
Process 1: (1 x 10) + (0.75 x 16) = 22 hours
Process 2: (0.75 x 10) + (1 x 16) = 23.5 hours
Process 3: (1 x 10) + (0.5 x 16) = 18 hours.There are enough hours available in Processes 1 and 3 to be able to make the maximum demand.
However Process 2 only has 22 hours available and therefore they cannot make the maximum demand and this process is the bottleneck.
