jMarkov and jPhase: object-oriented tools for modeling and so`lving large-scale Markov Chains and represent Phase-Type distributions. Visit the jMarkov website at COIN-OR . This tool facilitates the development of large-scale Markov chains. It is composed of four modules: jMarkov (to build and analyze Markov chains); jQBD (for Quasi-Birth-and-Death processes); jPhase (to represent Phase-Type distributions); and jMDP (for Markovian Decision Processes).
More details on these tools can be found on the papers: Algorithm 972: JMarkov: An Integrated Framework for Markov Chain Modeling.

Q-MAM: A MATLAB toolbox for solving Infinite Queues using Matrix Analytic Methods (Visit the website). This tool requires the SMCSolver tools, which can be found here.
This tool is composed of a set of MATLAB functions (i.e., .m files) to compute the queue length, waiting time and delay distributions of various queueing systems of infinite size. It includes, among others, implementations of the following queueing models, both in discrete and continuous time: PH/PH/1, MAP/MAP/1, MAP/M/c, MAP/D/c, RAP/RAP/1, MMAP[K]/PH[K]/1, MMAP[K]/SM[K]/1, SM[K]/PH[K]/1. State-of-the-art solution techniques are used to solve these models efficiently.
