Journal ArticleDOI
Environs: Relativistic Elementary Particles for Ecology
TL;DR: It is suggested that ecology lacks an elementary particle of its own, with discoverable properties that can clarify the nature of environment and its relationship to life, and what is known about it and some directions for learning more.
Journal ArticleDOI
Modeling formalisms for dynamic structure systems
TL;DR: A new concept for a system network to represent systems that are able to undergo structural change is presented, and three new system specifications are derived that provide a shorthand notation to specify classes of dynamic structure systems.
Journal ArticleDOI
A multimodel methodology for qualitative model engineering
TL;DR: A methodology and formalism for developing multiple, cooperative models of physical systems of the type studied in qualitative physics that combines discrete-event and continuous models and offers an approach to building intelligent machines capable of physical modeling and reasoning.

An Initial Theory of Value-Based Software Engineering
Barry Boehm,Apurva Jain +1 more
TL;DR: This chapter presents an initial “4+1” theory of value-based software engineering (VBSE), which addresses the questions of “which values are important?” and “how is success assured?’ for a given software engineering enterprise.
Journal ArticleDOI
An integrated approach to system modeling using a synthesis of artificial intelligence, software engineering and simulation methodologies
TL;DR: This work presents a perspective that serves to characterize simulation models in terms of their procedural versus declarative orientations, and has had considerable success in relating the field of modeling within computer simulation to other subdiscipline within computer science.
