Consider the following batch flow process consisting of three process steps performed by three machines.

Step 1 0.34/min/unit set up 36 min Step 2 0.27 min/unit set up 30 min Step 3 0.21 min/unit set up 45 min.

Compare the set-up times and task times for each step. Which statement is true?

a)Step 2 will always be faster than step 1 for every batch size-Step 2 will never be the bottleneck

b) Step 3 will always be faster than step 1 for every batch size-Step 3 will never be the bottleneck

c)Step 3 will always be faster than step 2 for every batch size-Step 3 will never be the bottleneck

d)Step 3 will always be faster than step 1 for every batch size-Step 3 will never be the bottleneck
