Among the major trends in health care that relate to OSCM is the increased use of gene
therapy.
Job design is defined as the function of specifying the work activities of an individual
or group in an organizational setting.
In a department 25 machines are kept running by three operators who respond to
randomly occurring equipment problems. An analyst who wanted to know how much
production was being lost by machines waiting for service could use queuing theory
analysis to find out.
In causal loop analysis, reinforcing loops generate increase or decrease in a measure in
which the increase or decrease, if left unmodified, would continue at an ever-increasing
rate.
An organizationally driven reason for outsourcing is that it can improve effectiveness
by focusing on what the firm does best.
One of the many lean techniques that have been successfully applied in service firms is
the upgrading of quality.
In recent surveys, about 55 percent of all Americans said they were dissatisfied with the
quality of health care.
You time someone completing a single task the first time at 100 minutes, and the fourth
time they do the task it takes 81 minutes. You should use a 90 percent learning curve to
estimate the length of time this worker will take to complete this task in the future.
Because little or no inventory is carried in a service operation, it is easy to separate the
operations management functions from marketing in services.
The term “dependent events” refers to a process sequence.
When a make-to-order production process is used, production is based on forecasts.
If it takes a supplier 2 days to deliver an order once it has been placed and the daily
demand for 3 days has been 120, 124, and 125, which of the following is the standard
deviation of usage during lead time?A. About 2.16
B. About 3.06
C. About 4.66
D. About 5.34
E. About 9.30
The standard deviation (Equation 20.6) of daily demand = Square root of (14/3) =
2.1602. This number squared is 4.6667. The square root of 2 days x 4.6667 = the square
root of 9.3333 or 3.055.
You are developing an X-bar chart based on sample means. You know the standard
deviation of the sample means is 4, the desired confidence level is 99 percent, and the
average of the sample means is 20. Which of the following is your LCL?
A. 36
B. 24
C. 9.68
D. 16.79
E. 30.32
Which of the following priority rules used in scheduling the sequence of production is
calculated as the slack time remaining in the schedule divided by the number of
remaining operations, with the smallest value being run first?
A. STR
B. Johnson’s
C. STR/OP
D. LCFS
E. FCFS
If it takes a supplier 4 days to deliver an order once it has been placed and the standard
deviation of daily demand is 10, which of the following is the standard deviation of
usage during lead time?A. 10
B. 20
C. 40
D. 100
E. 400
From Equation 20.8, the standard deviation of usage during lead time is equal to the
square root of the sums of the variances of the number of days of lead time. Because
variance equals standard deviation squared, the standard deviation of usage during lead
time is the square root of [4 x (10 x 10)] = square root of 400 = 20.
How often are major software changes typically made to ERP?
A. Every 12 months
B. Every 1 to 2 years
C. Every 3 to 5 years
D. Every 5 to 10 years
Which of the following is a characteristic of a well-designed service system?
A. Provides an unconditional service guarantee.
B. Each element of service system is consistent with the operating focus of the firm.
C. The front end of the service encounter is equal to the back end.
D. It segments the pleasure for the customer.
E. It lets the customer control the process.
A BOM file is also called which of the following?
A. Product tree
B. Stocking plan
C. Inventory usage record
D. Production parts plan
E. Time bucket schedule
For a mid-volume type of manufacturing, which of the following is the typical
production scheduling approach?
A. Finite forward scheduling
B. Finite backward scheduling
C. Infinite forward scheduling
D. Infinite backward scheduling
E. Precision forward scheduling
Which of the following is not a characteristic that distinguishes services from goods?
A. Service jobs are unskilled.
B. A service is intangible.
C. Services are perishable.
D. Services are heterogeneous.
E. None of these
In general, which forecasting time frame is best to detect general trends?
A. Short-term forecasts
B. Quick-time forecasts
C. Long-range forecasts
D. Medium-term forecasts
E. Rapid-change forecasts
Which of the following industry types will not benefit greatly from the application of
MRP?
A. Fabricate-to-order
B. Assemble-to-stock
C. Assemble-to-order
D. Manufacture-to-order
E. None of these
Which is the most challenging kind of supply chain to manage according to Hau Lee?
A. Agile supply chain
B. Efficient supply chain
C. Risk-hedging supply chain
D. Erratic supply chain
E. Responsive supply chain
Using the cut-and-try method for aggregate operations planning, we can determine the
production requirement in units of product. If the beginning inventory is 400 units, the
demand forecast is 900 units, and the required safety stock is 10 percent of the demand
forecast, what is the production requirement? _________________________________

developing a process-intensive product?

took 1 minute to produce the first unit, what will be the total time to produce 1,000
units? ______________________
