1 Chapter 6 Problem 14 Text Data minutes hours days 50 p = NO U A 24 0.4 0.016667 120 2 0.083333 w = 14. Markland First National Bank of Rolla utilizes kanban techniques in its check processing facility. The following information is known about the process. Each kanban container can hold 50 checks and spends 24 minutes a day in processing and 2 hours a day in materials handling and waiting. Finally, the facility operates 24 hours per day and utilizes a policy variable for unforeseen contingencies of a = k= 0.25 20 10 a. 0.25. 11 Using consistent time units a= ck / (p+w) (1 + a) 5.555556 333.3333 8000 8000 8000 13 supBubbuggan a. If there are 20 kanban containers in use, what is the current daily demand of the check processing facility? - b. If the muda or the waste in the system were eliminated completely, how many containers would then be needed? 15 b. 16 Removing the waste (waiting time) W = 17 19 20 k= a (p+w) (1 +a)/c 3.333333 4 containers 21 The calculation of the hourly demand of the check processing facility may be expressed as:Explanation / Answer
Hourly demand of the check processing facility can be obtained as below:
No. of checks per kanban, c = 50
No. of kanbans, k = 20
No. of checks in 20 kanbans = 50*20 = 100
Processing time, p = 24 minutes per day = 0.01667 days
Material handling and waiting time, w = 2 hours per day = 0.08333 days
Policy variable, a = 0.25
Now, Hourly demand of the check processing facility = c*k / [(p+w)*(1+a)*24]
= 100 / [(0.01667+0.08333)*(1+0.25)*24]
= 100 / [0.1*1.25*24]
= 100/3
= 33.33
None of these options provided gives the answer. Hence correct choice is none of these.
