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.

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 ...
RUCAPS (Really Universal Computer-Aided Production System) is a computer-aided design (CAD) system for architects, first developed during the 1970s and 1980s, and today credited as a forerunner of building information modeling (BIM). It runs on minicomputers from Prime Computer and Digital Equipment Corporation (DEC).
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 ...
The first known prominent public usage of the term "Model-Based Systems Engineering" is a book by A. Wayne Wymore with the same name. [8] The MBSE term was also commonly used among the SysML Partners consortium during the formative years of their Systems Modeling Language (SysML) open source specification project during 2003-2005, so they could distinguish SysML from its parent language UML v2 ...
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 ...
Martin Richards (born 21 July 1940) is a British computer scientist known for his development of the BCPL programming language [3] which is both part of early research into portable software, and the ancestor of the B programming language invented by Ken Thompson in early versions of Unix and which Dennis Ritchie in turn used as the basis of his widely used C programming language.
