Capacity is directly related to: (Choose all that apply)
output
but whatelse
Equipment utilization is normally expressed as a percentage of design capacity.
True
Which of these in not an approach to capacity planning?
forecasting
"Economies of scale" means that large factories operating a planned capacity are able to make many different products at the same time and promise short delivery times.
False
Foundries owe much of their success to:
Flexibility
Benefits received from "economies of scale" include: (Choose all that apply)
-volume purchases of materials and supplies
-lower cost per unit produced
-a steady stream of customer orders
Which of these is a proper application of the learning curve? (Choose all that apply)
-When production processes are highly automated
-When the supplier is using a new process
Because they are paying for the contract, the buyer's company should receive the cost savings from a learning-curve application.
False
The output of a factory can be no higher than the output of the slowest machine, the constraint of the system.
True
The first step in the Theory of Constraints is to:
Identify the bottleneck
Which of these is a true statement? (Choose all that apply)
-A system can have more than one bottleneck.
-A factory's bottleneck can change depending on what products are being made.
-According to the Theory of Constraints, each machine should operate at its maximum throughput.
The simplest way to think about throughput is the quantity of work completed.
False
Throughput is generally equal to which thing?
Arrival Rate
Throughput is a ...?
Rate
Little's Law states there is a relationship between: (Choose all that apply)
-Inventory
-Flow Time
-Throughput
-Output
Throughput, sometimes referred to as output rate, is expressed in units produced per hour.
False
If you maintain inventory at a constant level and keep the throughput rate constant:
Customer delivery dates become more reliable
"Queuing" means the scientific study of the use of the letter Q in the English language.
False
Which of the following results in waiting lines?
Variability
Which of the following are the components of a queuing system? (select all that apply)
-Servers
-Waiting Area
-Arrivals
-Computers
What can managers do with queuing theory?
Measure and predict preformance
The "C's" in the equation for the general queue stand for "Coefficient of Variation."
True
"tp" stands for "average service" time and can be found by taking the inverse of which thing?
Service Rate
The second, simpler formula is only valid for which condition?
The arrival and service rates are derived from a Poisson distribution
Utilization is equal to which of the following?
Arrival rate divided by service rate
The saturation effect says that queuing performance changes with utilization in a steady, straight line.
False
Increasing which of the following causes degraded queuing performance according to the saturation effect? (choose all that apply)
-Utilization
-Line Length
-System Size
Which statement best describes the performance curve of a queuing system as system utilization approaches 100%:
Congestion and delays skyrocket
An example of a short-term capacity increase decision is:
Adding low- skilled labor
Continual improvement of processes is important because:
-Competitors are improving their processes.
-Customer preferences change over time.
-Technology is constantly changing.

ans: all of these
Subcontracting is typically considered at what time horizon when doing capacity planning?
medium-term
Which two of the following effects directly result from bottlenecks?
Decrease in output and increase in lead-times.
Process thinking causes managers to address critical process elements, including:
If you don't like the outcome, change the process
A process having the same activity being performed by two or more resources simultaneously is said to have what kind of structure?
parallel
