Question
one of Detroit's thermostatic's inc (DTI) Newer products, the XJM-60 controller, was developed for a new model of thermostats to be introduced in 2011. Since this product is a modified version of an earlier controller, the assembly process to produce the controller had to be redesigned. Listed in the picture are the station times in minutes .
A. What is the cycle time for the new XJM-60 line?
B. What is the efficiency of the new XJM-60 line?
C. If workers are paid an average of $17.50 per hour on the new XJM-60 line, how much money is lost during the 40 hour work week due to balance delay?
D. What is the present annual or nominal hourly output rate of the old controller?
E. With average efficiency of workers at each station, what worker would you assign to each station on the new XJM-60 line to achieve highest hourly output rate? What level of hourly output rate can be achieved?
Please help!
5. One of Detroit Thermostatics Inc.'s (DT) newer products, the XJM-60 controller, model of thermostats to be introduced in 2011. Since this was developed for a nevw product is a modified version of an earlier controller, the assembly process to produce the controller had to be redesigned. (15 Points) Listed below are the stati new XJM-60 controller. There is one worker at each station. on times in minutes to assemble the old controller and the Station Old Controller XIM-60 1.9 1.8 2.2 2.4 2.0 2.2 2.1 A. What is the Cycle time for the new XJM-60 line? B. What is the efficiency of the new XJM-60 line? C. If workers are paid an average of $17.50 per hour on the new XJM-60 line, how much money is lost in 40 hour work week due to balance delay? Currently the following workers are assigned to each station for the production of the old controller as follows Worker Station Ave. Efficiency William 1 Ken Meghan 2 Lizabeth 5 Thomas 3 100% 120% 90% 100% 110% D. What is the present actual or nominal hourly output rate (in units/hr) for the production of the old controller? Assuming the workers experience the same average efficiency regardless of which assembly station they work at, what worker would you assign to each station on the new XJM-60 line to achieve the highest possible hourly output rate? What level of hourly output can be achieved, given these new assignments? E.Explanation / Answer
Number of work station (given) = 5
Total task time with new XJM -60 = 10 minutes
Formula is Number of work station = Total task time /Cycle time (CT)
5 = 10 / CT
(a) CT = 10/5 = 2 minute per unit
(b) Avg Efficiecy of the new XJM - 60
From the above given table of efficiency (station wise) it is clear that minimum efficiency is of stattion 2 i.e. 90%, acting as a bottleneck.
Therefore here the avg efficiency will be 90 %
(d) Hourly output rate of old controller =?
We know Cycle time = Production time available /Output rate
CT for old controller is = Total task time / No of station = 10.2 minutes/ 5 =2.04 minute per unit
then output rate (hourly) = Production time / Cycle time = 40 hour work week / 2.04 = 40 X 60 / 2.04 = 1,176 unit per hour
(c) workers are paid as $ 17.5 per hour for the new line where the efficieency is 90 % means the balance delay is 10%.
actual working time is 40 hour per week (100 % efficioency) but
it will be 36 hours per week in case of 90% efficiency.
Therefore payment loss would be = 40 X 17.5 - 36 X 17.5 = $ 70 per week.
(e) Since the worker Ken is giving the highest efficiency 120% , that' s why we will take ken into consideration.
then the hourly output rate will be = production time per week /cycle time
= 40 X 60 / 2 = 1200 units per hour
