Conceptual models are best thought of as design-tools – a way for designers to straighten out and simplify the design and match it to the users' task-domain, thereby making it clearer to users how they should think about the application.
Holland's and Kauffman's work, together with Dawkins' simulations of evolution and Varela's models of autopoietic systems, provide essential inspiration for the new discipline of artificial life, This approach, initiated by Chris Langton (1989, 1992), tries to develop technological systems (computer programs and autonomous robots) that exhibit lifelike properties, such as reproduction, sexuality, swarming, and co-evolution.john henry holland
The use of Enterprise Architectures is becoming increasingly widespread in the private sector. Borrowing insights from enterprise reference architectures developed during the last decade, IT vendors and companies belonging to specific industries are establishing reference data and process models advancing the standardisation of their businesses and creating a more integrated environment for their activities. Although public administrations share the same problem of non-standardisation, which is being magnified rapidly in a changing and demanding environment, little has been done so far in the direction of integration...
The successes of modern control theory in the design of highly accurate space navigation systems have stimulated its use in the theoretical analyses of economic and biological systems. Similarly, the effectiveness of computer simulation techniques in the macroscopic analyses of physical systems has brought into vogue the use of computer-based econometric models for purposes of forecasting, economic planning, arid management.
If the system exhibits a structure which can be represented by a mathematical equivalent, called a mathematical model, and if the objective can be also so quantified, then some computational method may be evolved for choosing the best schedule of actions among alternatives. Such use of mathematical models is termed mathematical programming.george dantzig
It has been very humbling and gratifying to have these men as our role models... Your generation enabled America to close out the twentieth century as the greatest nation in the history of mankind, the only remaining superpower, the world's leading economy and the world's most respected and feared military force in the world- respected by our friends and allies, feared by our adversaries.eric shinseki
One can always find inflationary models to explain whatever phenomenon is represented by the flavour of the month.joseph silk
For the theory-practice iteration to work, the scientist must be, as it were, mentally ambidextrous; fascinated equally on the one hand by possible meanings, theories, and tentative models to be induced from data and the practical reality of the real world, and on the other with the factual implications deducible from tentative theories, models and hypotheses.george e. p. box
Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful.george e. p. box
Essentially, all models are wrong, but some are useful.george e. p. box
In Stage I, divorces were not allowed, so men's [sexual] affairs did not put women's economic security in jeopardy; in Stage II, affairs could lead to divorce, so men's affairs did place women's economic security in jeopardy. We did not want political leaders who would be role models for behavior that would put women's economic security in jeopardy.warren farrell
It's a pity, a gentleman in refined retirement composing poetry: He models his work on the classic verse of China. And his poems are elegant, full of fine phrases. But if you don't write of things deep in your own heart, What's the use of churning out so many words?ryōkan
The Greeks put us to shame not only by their simplicity, which is foreign to our age; they are at the same time our rivals, nay, frequently our models, in those very points of superiority from which we seek comfort when regretting the unnatural character of our manners. We see that remarkable people uniting at once fullness of form and fullness of substance, both philosophising and creating, both tender and energetic, uniting a youthful fancy to the virility of reason in a glorious humanity.friedrich von schiller
Stale is stale and borrowed is borrowed, no matter how original your models may have been.robert silverberg
When one turns to psychological models of mental illness, one finds that the psychodynamic model of human mind and of mental disease is also of considerable antiquity. Thus, Empedocles of Agrigentum (490-430 B.C.) from whom Hippocrates took the theory of four elements, stressed the importance of emotions of love and hate as the controlling agents of human behavior and of physiological functions.
The best way to support dreams and stretch is to set apart small ideas with big potential, then give people positive role models and the resources to turn small projects into big businesses.
Executable UML (xUML) consists of UML class diagrams, UML state machines and an action language which complies with the UML action semantics. There are several action languages in use; we refer to for a somewhat limited overview. The xUML models to be translated are expressed in the Cassandra/xUML dialect, as developed by KnowGravity.
[The] company’s Chief Information Officer (CIO) should guide the rationale behind the development of EA models. In particular, distribution of IT related information and knowledge throughout the organization is emphasized as an important concern uncared for. Secondly, the lack of architectural theory is recognized...
An organization chart is a convenient place to begin building planning models. A Note that as an organization is an object, so are the organization units. An organization chart depicts an object aggregation hierarchy
Much of my work in this period was concerned with exploring the logic of economic models, but also with attempting to reconcile the models with every day observation.
Here I had tried a straightforward extrapolation of technology, and found myself precipitated over an abyss. It’s a problem we face every time we consider the creation of intelligences greater than our own. When this happens, human history will have reached a kind of singularity a place where extrapolation breaks down and new models must be applied and the world will pass beyond our understanding.

Some form of self-awareness is surely essential to highly intelligent thought... On the other hand, I doubt that any part of a mind can see very deeply into other parts; it can only use models it constructs of them.
Today, nearly all biologists acknowledge that evolution is a fact. The term theory is no longer appropriate except when referring to the various models that attempt to explain how life evolves. ... It is important to understand that the current questions about how life evolves in no way implies any disagreement over the fact of evolution.
