This module defines some useful predefined servers that hold the current process for the corresponding random time interval, when processing every input element.

Synopsis

Documentation

newRandomUniformServer Source

Arguments

:: Double	the minimum time interval
-> Double	the maximum time interval
-> Simulation (Server () a a)

Create a new server that holds the process for a random time interval distributed uniformly, when processing every input element.

By default, it is assumed that the server process cannot be preempted, because the handling of possible task preemption is rather costly operation.

newRandomUniformIntServer Source

Arguments

:: Int	the minimum time interval
-> Int	the maximum time interval
-> Simulation (Server () a a)

Create a new server that holds the process for a random time interval distributed uniformly, when processing every input element.

By default, it is assumed that the server process cannot be preempted, because the handling of possible task preemption is rather costly operation.

newRandomTriangularServer Source

Arguments

:: Double	the minimum time interval
-> Double	the median of the time interval
-> Double	the maximum time interval
-> Simulation (Server () a a)

Create a new server that holds the process for a random time interval having the triangular distribution, when processing every input element.

By default, it is assumed that the server process cannot be preempted, because the handling of possible task preemption is rather costly operation.

Arguments

:: Double	the mean time interval
-> Double	the time interval deviation
-> Simulation (Server () a a)

Create a new server that holds the process for a random time interval distributed normally, when processing every input element.

By default, it is assumed that the server process cannot be preempted, because the handling of possible task preemption is rather costly operation.

-> Double	the deviation of a normal distribution which this distribution is derived from
-> Simulation (Server () a a)

Create a new server that holds the process for a random time interval having the lognormal distribution, when processing every input element.

By default, it is assumed that the server process cannot be preempted, because the handling of possible task preemption is rather costly operation.

Arguments

:: Double	the mean time interval (the reciprocal of the rate)
-> Simulation (Server () a a)

Create a new server that holds the process for a random time interval distributed exponentially with the specified mean (the reciprocal of the rate), when processing every input element.

By default, it is assumed that the server process cannot be preempted, because the handling of possible task preemption is rather costly operation.

-> Int	the shape
-> Simulation (Server () a a)

Create a new server that holds the process for a random time interval having the Erlang distribution with the specified scale (the reciprocal of the rate) and shape parameters, when processing every input element.

By default, it is assumed that the server process cannot be preempted, because the handling of possible task preemption is rather costly operation.

-> Simulation (Server () a a)

Create a new server that holds the process for a random time interval having the Poisson distribution with the specified mean, when processing every input element.
