Question

Consider a four-step serial process with processing times given in the list below. There is one machine at each step of the process and this is a machine-paced process.

Step 1: 26 minutes per unit
Step 2: 16 minutes per unit
Step 3: 23 minutes per unit
Step 4: 26 minutes per unit

Assuming that the process starts out empty, how long will it take (in hours) to complete a batch of 91 units?

Answer 1

40.22 hours

Step-by-step explanation:

The computation of the time taken as follows:

= 26 minutes × 91 units

= 2,366

In hours

= 2,366 ÷ 60 minutes

= 39.43

The total time taken for machine step is

= 16 + 23

= 39 minutes

So, the total time taken is

= 39.43 + 39 minutes

= 40.22 hours
