In a process sequence where a product flows from process A to process B, process A is
called the mother process.
A -chart has upper and lower control limits expressed as lines on the chart. As long as
the sample values fall between these two lines, there is no need to investigate process
behavior.
MRP provides the schedule specifying when each part and component of an end item
should be ordered or produced.

Total, 100 percent inspection can never be cost justified.
Process selection refers to the strategic decision of choosing the volume of output to
produce in a manufacturing facility depending upon the way that facility produces.
“Green belt” programs are coordinated public works projects aimed a placing an
environmentally friendly zone around major cities.
Effective management of services requires a clear focus on understanding operations, so
much so that it may even require the exclusion of consideration of marketing or

The Poisson probability distribution is used in waiting line management when one is
interested in the number of arrivals to a queue during some fixed time period.
Among the major trends in health care that relate to OSCM is integrated medical care.
Most services consist of a bundle of goods and services known as the service package,
which is the major output of the development process.
You time someone completing a single task the first time at 10 minutes, and the second
time they do the task it takes 9 minutes. You should use an 80 percent learning curve to
estimate the length of time this worker will take to complete this task in the future.
Looking at the loads that are placed on each resource by the products that are scheduled

Using the assembly-line balancing procedure, what is the required cycle time if the
production time in minutes per day is 2,400 and the required output per day in units is
1,200? _________________________________
In setting up a kanban control system, you need to determine the number of kanban
card sets needed. If the expected demand during lead time is 24 per hour, safety stock is
10 percent of the demand during lead time, the container size is 5, and the lead time to
replenish an order is 5 hours, what number of kanban card sets is needed?
