Question

level scheduling (heijunka)
assume:

• one assembly line produces a mix of models and option combinations
• production plan may call for 1500 sunroofs in the coming month
• assume 25 production days in the coming month, 15 hours of production each day

what is the cycle time needed to achieve the required production of 1500 sunroofs next month?

Explanation:

Step1: Calculate total production hours

Total hours = $25 \times 15 = 375$ hours

Step2: Convert hours to minutes

Total minutes = $375 \times 60 = 22500$ minutes

Step3: Compute cycle time

Cycle time = $\frac{\text{Total production time}}{\text{Required output}}$
$\text{Cycle time} = \frac{22500}{1500} = 15$ minutes

Answer:

15 minutes
