If you want to reduce process flow time, it has been suggested that you can perform

and possibly even managed is called assignable variation.
On a learning curve plot, the time per unit is usually displayed on the vertical axis.
The customer arrivals in a queuing system come almost exclusively from finite

Using the fixed-time-period inventory model, and given an average daily demand of 75
units, 10 days between inventory reviews, 2 days for lead time, 50 units of inventory on
hand, a service probability of 95 percent, and a standard deviation of demand over the
review and lead time of 8 units, which of the following is the order quantity?A. 863
B. 948
C. 1,044
D. 1,178
E. 4,510
The z score for a service probability of 95 percent is 1.64. Using Equation 20.11, q = 75
x (10 + 2) + (1.64 x 8) – 50 = 900 + 13.12 – 50 = 863.12 = 863.

D. The mean has not shifted at all.
E. The true capability index value is between 2 and 2.5.
Given a prior forecast demand value of 230, a related actual demand value of 250, and a

the following period?
A. 230
B. 232
C. 238
D. 248
E. 250

C. Do not allow bottlenecks to govern the flow of the line.
D. An hour saved at a bottleneck operation is a mirage.E. The amount in a process batch
should be fixed when the batch is begun and not changed over time or along its route.
A company wants to determine where it should locate a new warehouse. It has two
existing production plants (i.e., plant A and plant B) that will ship units of a product to
this warehouse. Plant A is located at the (X, Y) coordinates of (50, 100) and will have
volume of shipping of 250 units a day. Plant B is located at the (X, Y) coordinates of
(150, 200) and will have a volume of shipping of 150 units a day. Using the centroid
method, which of the following are the X and Y coordinates for the new plant location?
A. (81, 117)
B. (88, 138)
C. (117, 102)
D. (76, 123)
E. X and Y coordinates cannot be computed from the data given.
In setting up a kanban control system you need to determine the number of kanban card
