umontreal.iro.lecuyer.contactcenters.app.EstimationType
public enum EstimationType
Represents the type of estimation specified for a group of performance measures. The estimation type gives clues on how performance measures are estimated.
Enum Constant Summary | |
---|---|
EXPECTATION
Estimation of an expectation, by an average in the case of simulation. |
|
EXPECTATIONOFFUNCTION
Estimation of the expectation of a function of several random variables whose expectations are themselves represented by other types of performance measures. |
|
FUNCTIONOFEXPECTATIONS
Estimation of a function of multiple expectations, e.g., a ratio of expectations. |
|
RAWSTATISTIC
Raw statistics which do not estimate expectations. |

public static final EstimationType EXPECTATION
PerformanceMeasureType.RATEOFABANDONMENT
is defined as the expected rate of contacts
having abandoned without receiving service during some time interval.
Types of performance measures whose names begin with
SUM are also normalized the same way as rates.
By default, rates are considered relative to one main period, so
PerformanceMeasureType.RATEOFABANDONMENT
corresponds to the expected number
of contacts having abandoned during a main period.
However, if the normalizeToDefaultUnit
attribute in simulation parameters is set to true,
rates are treated as relative to one simulation time unit.
Expected
time-averages, which are not normalized as rates,
are part of groups with names beginning with AVG,
e.g., PerformanceMeasureType.AVGQUEUESIZE
for the time-average queue size.

, and
PerformanceMeasureType.ABANDONMENTRATIO
. For now, these
functions are ratios estimated as follows.
Let
(X0, Y0),…,(Xn-1, Yn-1) be
random vectors generated during an experiment. Pairs of
observations can come from independent replications or from batches,
depending on the method of experiment.
