Question

4. One of Canadian Air Conditioners Inc. (CAC) newer products the TMP-20 thermostat, was developed for a new model of air conditioners to be introduced in 2014. Since this product is a modified version of an earlier thermostat, the assembly process to produce the thermostat had to be redesigned Listed below are the station times in minutes to assemble the old thermostat and the new TMP-20 thermostat Station Old Thermostat TMP-20 1.7 2 3 4 5 1.7 1.8 2.5 2.4 1.9 2.2 2.3 2.1 A. What is the Cycle time of the TMP-20 line? B. What is the Efficiency of the TMP-20 line? C. If each worker is paid $21.00 per hour on the TMP-20 line, how much money is lost in a 10 hour shift due to balance delay?

Answer 1

Answer A. The cycle time of the TMP-20 line is 2.3 minutes (highest cycle time among all the stations is for station 4).

Answer B. Efficiency of the TM-20 line = [Total Duration time / (Number of stations * Cycle time)] * 100

Total Duration Time = 1.7 + 1.8 + 2.2 + 2.3 + 2.1 = 10.1

Efficiency of the TM-20 line = [10 / (5x2.3)] x 100

= 87%

Answer C.

Balance delay = 100 – Efficiency

= 100 – 87

= 13 %

If shift is of 10 hours then balance delay = 10 x 13% = 1.3 hours

Money lost in a 10 hour shift due to balance delay = $21 x 1.3 hours = $27
