# The aivika package

Aivika is a multi-paradigm simulation library which has the following features:

allows defining recursive stochastic differential equations of System Dynamics (unordered as in maths via the recursive do-notation);

has a basic support of the event-driven paradigm of the Discrete Event Simulation (DES);

has a basic support of the process-oriented paradigm of DES with an ability to resume, suspend and cancel the discontinuous processes;

allows working with limited resources (you can define your own behaviour or use the predefined queue strategies);

allows customizing the queues (you can define your own behaviour or use the predefined queue strategies);

supports the activity-oriented paradigm of DES;

supports the basic constructs for the agent-based modeling;

allows creating combined discrete-continuous models;

the arrays of simulation variables are inherently supported (this is mostly a feature of Haskell itself);

supports the Monte-Carlo simulation;

the simulation model can depend on external parameters;

uses extensively the signals to notify the model about changing the reference and variable values;

allows gathering statistics in time points;

hides the technical details in high-level simulation monads (three of them support the recursive do-notation).

Aivika itself is a light-weight engine with minimal dependencies. However, it has additional packages Aivika Experiment [1] and Aivika Experiment Chart [2] that offer the following features:

automating the simulation experiments;

saving the results in CSV files;

plotting the deviation chart by rule 3-sigma, histogram, time series, XY chart;

collecting the summary of statistical data;

parallel execution of the Monte-Carlo simulation;

have an extensible architecture.

All three libraries were tested on Linux, Windows and OS X.
