Rhapsody was first released in 1996 by Israeli software company I-Logix Inc. [5] Rhapsody was developed as an object-oriented tool for modeling and executing statecharts, based on work done by David Harel at the Weizmann Institute of Science, who was the first to develop the concept of hierarchical, parallel, and broadcasting statecharts.
A few online and downloadable software tools help automate the ACH process. These programs leave a visual trail of evidence and allow the analyst to weigh evidence. PARC ACH 2.0 [17] [18] was developed by Palo Alto Research Center (PARC) in collaboration with Richards J. Heuer, Jr. It is a standard ACH program that allows analysts to enter ...
Differs from traditional system dynamics approaches in that 1) it puts much greater emphasis on probabilistic simulation techniques to support representation of uncertain and/or stochastic systems; and 2) it provides a wide variety of specialized model objects (beyond stocks, flows and converters) in order to make models less abstract (and ...

Originally developed for growth modelling, it allows for more flexible S-shaped curves. The function is sometimes named Richards's curve after F. J. Richards, who proposed the general form for the family of models in 1959.
The software produces finite difference equations that describe the graphical model and allows users to select a numerical analysis method to apply to the system, either the Euler method or various Runge–Kutta methods (either second or fourth order). [16] Before running a model, users may also specify a time step and runtime for the ...
