# The aivika package

**This is a package candidate release!** Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

**Warnings:**

- 'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit and not just imposing longer compile times on your users.
- Exposed modules use unallocated top-level names: Simulation

Aivika is a multi-method simulation library focused on discrete event simulation (DES) with partial support of system dynamics and agent-based modeling.

The library has the following features:

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

supports the event-driven paradigm of DES as a basic core for implementing other paradigms;

supports extensively the process-oriented paradigm of DES with an ability to resume, suspend and cancel the discontinuous processes;

allows working with the resources based on specified queue strategies (FCFS/FIFO, LCFS/LIFO, SIRO, static priorities and so on);

allows customizing the infinite and finite queues based on strategies too;

supports the resource preemption;

allows defining a queue network based on streams of data (transacts) and their processors;

allows simulating circuits with recursive links and delays;

supports the activity-oriented paradigm of DES;

supports basic constructs for the agent-based modeling such as agents, states, timeout and timer handlers;

allows creating combined discrete-continuous models as all parts of the library are well integrated and this is reflected directly in the type system;

the arrays of simulation variables are inherently supported;

supports the Monte-Carlo simulation;

the simulation model can depend on external parameters;

uses extensively signals for notification;

allows gathering statistics in time points;

hides technical details in high-level simulation computations (monads, streams and arrows).

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

automating 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;

has an extensible architecture.

The charting package has two interchangeable back-ends [3, 4], where one of them uses Cairo and it is more preferable.

The PDF documentation and installation instructions are available on the Aivika Wiki website [5].

Moreover, the method was generalized [6] and applied to nested simulation [7] and parallel distributed simulation [8].

The libraries were tested on Linux, Windows and OS X.

A more full information about Aivika is available on the project website [9].

P.S. Aivika is actually a genuine female Mari name which is pronounced with stress on the last syllable.
