Using the fixed-time-period inventory model, and given an average daily demand of 15
units, 3 days between inventory reviews, 1 day for lead time, 30 units of inventory on
hand, a service probability of 98 percent, and a standard deviation of daily demand is 3
units, which of the following is the order quantity?A. About 30.4
B. About 36.3
C. About 42.3
D. About 56.8
E. About 59.8
The z score for a desired service probability of 98 percent is 2.053. From Equation
20.12, the standard deviation during review and lead time is the square root of (4 x 3
squared), which is 6. Then, using Equation 20.11, q = 15 x (3 + 1) + (2.05 x 6) – 30 = 60
+ 12.3 – 30 = 42.3.
Which of the following is not a way that operations and supply processes are
categorized?
A. Planning
B. Return
C. Delivery
D. Selecting
E. Making

processes
C. Physically grouping machines and processes into cells
D. Disposing of leftover machinery and outsourcing ungrouped processes
E. None of these
A company can produce a small lot of products the first time at a cost of $10,000. If

A work center has five jobs assigned to it. They are labeled, in the order of their arrival
in the shop, as jobs A, B, C, D, and E. The work center may work on only one job at a
time and must complete any job it starts before starting another job. Job A has a
processing time of 6 days and is due to the customer in 9 days. Job B has a processing
time of 2 days and is due in 16 days. Job C has a processing time of 4 days and is due in
10 days. Job D has a processing time of 3 days and is due in 7 days. Job E has a
processing time of 5 days and is due in 12 days. Using the slack time remaining priority
rule, in what order should these jobs be undertaken?
