Which of the following steps should be first in determining operation start dates for capacity
planning?

• A. Input/output control
• B. Forward or backward scheduling
• C. Finite or infinite loading
• D. Order preparation and release

A work center has one machine that is operated for one shift per day. The shop runs an 8-hour shift 5
days per week. Machine utilization has been 60% with efficiency at 80%. A routing through this work
center has a standard run time of .10 hours per piece. Job number 1234 is for 200 pieces. If the
utilization is improved to 80%, the difference in calculated lead time for the job is how many days?

• A. 1.0
• B. 1.3
• C. 2.1
• D. 2.7

The average length of time a job must wait at a work center is a function of the:

• A. operation duration.
• B. estimated start date.
• C. planned size of the queue.
• D. transportation time to the work center.

When an order is split into two orders, the immediate effect on a job shop work center is to increase
which of the following elements?

• A. Setup time
• B. Work-in-process quantity
• C. Run time
• D. Lot size

A supplier of roller bearings makes lots of 10,000 and sorts them automatically according to size. In
a typical lot of 10,000, the sizes break into the categories:
The product requires rollers on target or, at most, 0.0001 oversize. Experience indicates that 100%
must be reinspected before use because the machine inspection lets a few defective units slip
through. The supplier should be encouraged to take which of the following actions?

• A. Learn what factors cause variability.
• B. Tighten the inspection criteria.
• C. Seek deviations from Quality Control.
• D. Doubly inspect the rollers

If an operation on a routing is performed out of sequence and the change in sequence is not
reported to the formal system, which of the following situations will occur?

• A. An alternate routing will be created.
• B. The capacity requirements planning data will be inflated.
• C. The order will appear on a dispatch list in the wrong work center.
• D. The error will be corrected by cost accounting.

In a continuous flow environment, it is necessary to report which of the following data from the shop
floor?

• A. Setups
• B. Material issues
• C. Defects and scrap
• D. Direct labor hours on and off an operation

The actual output of a work center for a given time period can be determined by evaluating the:

• A. number of standard hours in the queue.
• B. number of standard hours per units produced.
• C. number of machine hours.
• D. amount of rated capacity less rework.

Which of the following project characteristics would suggest using the PERT technique, rather than
the critical path method?

• A. Estimates of individual task times are probabilistic.
• B. Project tasks are backward scheduled.
• C. Due dates are needed to identify critical tasks.
• D. Project management can determine the critical path.

Statistical process control is a technique primarily used to:

• A. implement mistake-proofing techniques.
• B. identify special-cause variation.
• C. reduce preventive maintenance.
• D. reduce the number of inspection steps.
