Question

*Bethlehem Iron Works produces steel beams for the construction of bridges. The customer demand for the beams is 10 million per year. The production of the beams requires five different manufacturing operations, each in sequence. The net available time to work is 120 hours per week, with three shifts. Assuming the company shuts down completely for refurbishing when the workers take their two week vacation each year, what is the company’s Takt time for this product?

4.49 seconds

4.32 seconds

.012 hours

2.16 seconds

2.50 seconds

Explanation / Answer

Takt time is time available to produce one unit of the product and it is calculated as below:

Takt time = Net time available for work/Customer demand

Takt time = 21,600,000/10,000,000

Takt time = 2.16 seconds

Net time available for work = (52weeks -2 weeks)*120hours per week*3600seconds/hour

Net time available for work = 21,600,000 seconds
