Description
Tested with: GHC 7.8.3
This module defines random streams of events, which are useful for describing the input of the model.
- randomStream :: Parameter (Double, a) -> Stream (Arrival a)
- randomUniformStream :: Double -> Double -> Stream (Arrival Double)
- randomUniformIntStream :: Int -> Int -> Stream (Arrival Int)
- randomNormalStream :: Double -> Double -> Stream (Arrival Double)
- randomExponentialStream :: Double -> Stream (Arrival Double)
- randomErlangStream :: Double -> Int -> Stream (Arrival Double)
- randomPoissonStream :: Double -> Stream (Arrival Int)
- randomBinomialStream :: Double -> Int -> Stream (Arrival Int)
Stream of Random Events
Arguments
| :: Parameter (Double, a) | compute a pair of the delay and event of type |
| -> Stream (Arrival a) | a stream of delayed events |
Return a sream of random events that arrive with the specified delay.
Arguments
| :: Double | the minimum delay |
| -> Double | the maximum delay |
| -> Stream (Arrival Double) | the stream of random events with the delays generated |
Create a new stream with delays distributed uniformly.
Arguments
| :: Int | the minimum delay |
| -> Int | the maximum delay |
| -> Stream (Arrival Int) | the stream of random events with the delays generated |
Create a new stream with integer delays distributed uniformly.
Arguments
| :: Double | the mean delay |
| -> Double | the delay deviation |
| -> Stream (Arrival Double) | the stream of random events with the delays generated |
Create a new stream with delays distributed normally.
randomExponentialStream Source
Arguments
| :: Double | the mean delay (the reciprocal of the rate) |
| -> Stream (Arrival Double) | the stream of random events with the delays generated |
Return a new stream with delays distibuted exponentially with the specified mean (the reciprocal of the rate).
Arguments
| :: Double | the scale (the reciprocal of the rate) |
| -> Int | the shape |
| -> Stream (Arrival Double) | the stream of random events with the delays generated |
Return a new stream with delays having the Erlang distribution with the specified scale (the reciprocal of the rate) and shape parameters.
