The "Executive Secretary" is a chair that has been designed using ergonomics to provide comfort during long work hours. The chair sells for $130. There are 480 minutes available during the day, and the average daily demand has boon 52 chairs. There are eight tasks: Performance Time Task Must Follow (mins)Task Listed Below Task A, B F. G This oxercise only contains parts b, c, d, e, , and g b) The cycle time for the product n of a chair = minutes ound your esponse to t o decir does o) The theoretical minimum number of workstations (ound your response up to the next whole number), d) The assignment of tasks to workstations should be: C-Hint: Number workstations sequentialy in terms of precedence relationships and combine any applicable tasks.) Task Workstation Number Station 1 Enter your answer in each of the answer boxes.

Explanation / Answer

b) Cycle time = Total time in a day/Daily demand = 480/52 = 9.23 minutes

c) Theoretical number of workstation = Total task time/Cycle time = (5+8+7+6+7+7+8+5)/9.23 = 53/9.23 = 5.74

Hence, 6 stations

d) Assignment:

A = Workstation 1

Time left is 4.23 minutes so no other task can be assigned

As we can see, sum of any two task is greater than 9.23 minutes, so, no two task can be assigned in same workstation

Hence,

B = Workstation 2

C = Workstation 3

D = Workstation 4

E = Workstation 5

F = Workstation 6

G = Workstation 7

H = Workstation 8

No, we were not able to assign as per theoretical computation

e) Total idle time = Number of workstation*Cycle time - Total task time = 8*9.23 - 53 = 20.84 or 21 minutes
