As an equipment provider for several Olympic cyclists, Carbon Bike Frames (CBF) operates a very expensive wind tunnel facility near San Diego, CA. The wind tunnel is used to find thebest compromise between ergonomics and aerodynamics for the cyclist. Presently, more andmore cyclists are interested in CBFs services, so the company considers building a secondfacility. 

However, given the enormous costs of the wind tunnel, they also want to explore a more effective use of the current facility. An initial data collection reveals that:

 

-- The standard fitting time for a cyclist is 2h. On average, the wind tunnel is used for7 fitting procedures per working day (new customers or customers who want a refit). The wind tunnel is available 24 hours per working day.

 

-- CBF offers a free second session should the customer not be entirely satisfied with their bike fit (internally also known as rework sessions). About 2 out of 5 customers come back for such a refit, which takes the same amount of time as the initial fit.

 

--20minutesoftheeachfittingprocedure isspenton setting up the bike on a stationary trainer and getting the athlete ready. Almost all of this could happen outside the wind tunnel, i.e. while another fitting procedure is still going on.

 

-- About one day out of 10, the wind tunnel is down for maintenance or repair.

 

 

 

CBF1.How many new fits are conducted on a typical day when the wind tunnel is in use (assume the wind tunnel is open that day)?

 

CBF2.What is the OEE of the wind tunnel? Recall that the wind tunnel can be used 24h in a working day.

CBF1.)

 

On average 2 of 7 customers per day relief, wich leave 5 new customer per day.

 

 

 

CBF2.)

 

OEE=(100 min-add value time/customers*5 new customers per day*9 days/cycle)/(60min/hr*(24hr/day)*(10 days/cycle))=4500/14,400=0.3125
