Performance modeling tools with applications

This paper deals with the role of performance modeling tools. It introduces 3 major tool development centers and shows how a given tool can be applied to investigate the performance of a finite-source retrial queueing system

The Möbius state-level abstract functional interface

Abstract. A key advantage of the Möbius modeling environment is the ease with which one can incorporate new modeling formalisms, model composition and connection methods, and model solution methods. In this paper, we describe a new state-level abstract functional interface (AFI) for Möbius that allows numerical solution methods to communicate with Möbius state-level models via the abstraction of a labeled transition system. This abstraction, and its corresponding implementation as a set of containers and iterators, yields an important separation of concerns: It is possible to treat separately the problem of representing large labeled transition systems, like generator matrices of continuoustime Markov chains, and the problem of analyzing these systems. For example, any numerical solver (e.g., Jacobi, SOR, or uniformization) that accesses a model through the Möbius state-level AFI can operate on a variety of state-space representations, including “on-the-fly, ” disk-based, sparse-matrix, Kronecker, and matrix-diagram representations, withou
