" We often fail to realize how little we know about a thing until we attempt to simulate it on a computer " [Donald Knuth, 1968] Abstract The state-of-the art of psychological knowledge about the personality types is distilled to provide a basis for the specification of fuzzy agents with dynamic personality for the simulation of human behavior. The thirty… (More)
Dynamic model update and replacement are critical capabilities for modeling problems, the underlying processes of which are uncertain. The trajectory of most complex social phenomena, including conflicts, for instance, is never fixed and predictable. Symbiotic simulation is yet another emergent challenge that requires model adaptivity in response to… (More)
Data has strong impact on different aspects of scientific thinking. The article starts with a milestone example of the impact of data. Then clarifications are offered for some basic concepts such as, belief, fact, data, information, and knowledge. Three perceptions of simulation, namely non-scientific, scientific, as well as military views are outlined.… (More)
" The unexamined life is not worth living. " Socrates (469-399 BC) " What you don't want done to yourself, don't do to others. " Confucius (551-479) BC) Abstract Growing importance of and scope of application areas of modelling and simulation oblige us to reexamine our field and reflect upon whether or not those who are involved in any aspect of it have any… (More)
Knowledge – There are five groups of knowledge:-M&S body of knowledge (BoK) Examples to the growing importance of modelling and simulation (M&S) are given. The implications are highlighted in three categories: (1) Professional implications, (2) Ethical implications, and (3) Desirable research and development (R&D) areas in science, methodology, and… (More)
The significance of simulation modeling at multiple levels, scales, and perspectives is well recognized. However, existing proposals for developing such models are often application specific. The position advocated in this paper is that generic design principles for specifying and realizing multiresolution, multistage models are still lacking. Requirements… (More)
Nearly 60 types of machine understanding is presented in an ontology-based dictionary as a basis for the development of software agents with understanding abilities. Then a framework for software agents is presented.
The aim of this panel session is to promote discussion on emergent challenges and the need for advancements in the theory, methodology, applications, education in M&S. The changing landscape in science and engineering (e.g., industrial and defense application, medicine, predictive homeland security, energy and environment) introduces new types of problems… (More)
