TANGRAM-II is a modeling environment tool developed for research and educational purposes that provides a flexible user interface to describe computer and communication system models. It has a sophisticated graphic interface based on the public domain software package TGIF (Tangram Graphic Interface Facility) and an object oriented description language. The tool is a second and significantly more sophisticated version than the original prototype developed during the TANGRAM project. The current version is implemented in C++ and C and has several solvers for transient and steady state analysis of performance and availability metrics.
