Question

One of Detroit Motor Company's (DMC) newer products, the ABX-60 controller, was developed for a new model of trucks to be introduced in 2006. Since this product is a modified version of an earlier controller, the assembly process to produce the controller had to be redesigned. 4. Listed below are the station times in minutes to assemble the old controller and the new ABX 60 controller. There is one worker at each station Station ABX-60 1.9 1.8 2.2 2.4 1.8 1.9 2.0 2.2 2.1 A. What is the Cycle time of the ABX-60 line? B. What is the efficiency of the ABX-60 line? If each worker is paid $14.00 per hour on the ABXABX-60 line, how much money is lost in an 8 hour day due to balance delay? C.

Explanation / Answer

Answer

A. Cycle time of the ABX-60 : Add the lead time of each operations from operation 1 to 5, it will gives the lead time of the ABX-60, as below

ABX-60 lead time = 1.8+1.9+ 2.0+2.2+2.1 = 10.0 minutes.

B. HIgher Efficiency of ABX-60 = (lead time difference (old -ABX-60) /The lead time of old controller)*%

Higher Efficiency of ABX-60 = ((10.2 -10.0)/10.2)*100

Higher Efficiency of ABX-60 = 2 %

Thus the efficient of new ABX-60 controller is higher by 2% compared to the efficiency of old controller.

Answer C : The total delay lossin dollars is $ 50.91, as calculated below

Lead time Delay in each station per 2.2 min. Delay in 8 hours = 8*60=480 Total Delay in 8 hours (min) Total Delay
(in hours) Total loss for total delay@ $14/hoiur 1.8 0.4 (0.4/2.2)*480 87.3 1.45 $        20.36 1.9 0.3 (0.3/2.2)*480 65.5 1.09 $        15.27 2.0 0.2 (0.2/2.2)*480 43.6 0.73 $        10.18 2.2 0.0 0 0.0 0.00 $               -   2.1 0.1 (0.1/2.2)*480 21.8 0.36 $          5.09 Total $        50.91
