The aivika package
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 .
Moreover, the method was generalized  and applied to nested simulation  and parallel distributed simulation .
The libraries were tested on Linux, Windows and OS X.
A more full information about Aivika is available on the project website .
P.S. Aivika is actually a genuine female Mari name which is pronounced with stress on the last syllable.
