ⓘ Conceptual modelling ..


Ecopath with Ecosim is a free and open source ecosystem modelling software suite, initially started at NOAA by Jeffrey Polovina, but has since primarily been developed at the formerly UBC Fisheries Centre of the University of British Columbia. In 2007, it was named as one of the ten biggest scientific breakthroughs in NOAAs 200-year history. The NOAA citation states that Ecopath "revolutionized scientists ability worldwide to understand complex marine ecosystems". Behind this lie more than two decades of development work in association with Villy Christensen, Carl Walters, Daniel Pauly, an ...

Explanatory model

An explanatory model is a useful description of why and how a thing works or an explanation of why a phenomenon is the way it is. The explanatory model is used as a substitute for "the full explanation" of the thing in question: or because the full explanation is too cumbersome to be practical in the case at hand. either because the full explanation is unavailable Explanatory models do not claim to be a complete description/explanation of the absolute about the thing/phenomenon, nor do they even claim to, necessarily, be fully accurate. The description/explanation does, however, need to fi ...

Imago Universi

Imago universi in Latin means "image of the universe". In the Middle Ages the expression was used to express the representation and size of the known world at that time. Cartographer Andreas Cellarius described his star atlas Harmonia Macrocosmica, published 1660, as "Imago universi secundum Ptolaeum" English: "Picture of the Universe according to Ptolemy". "Imago universi: una historia de la concepcion humana del cosmos" is the title of two volumes in Spanish on cosmology.

Interpretation (philosophy)

A philosophical interpretation is the assignment of meanings to various concepts, symbols, or objects under consideration. Two broad types of interpretation can be distinguished: interpretations of physical objects, and interpretations of concepts.

Mathematical model

A mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in the natural sciences and engineering disciplines, as well as in the social sciences. A model may help to explain a system and to study the effects of different components, and to make predictions about behaviour.

Mental model

A mental model is an explanation of someones thought process about how something works in the real world. It is a representation of the surrounding world, the relationships between its various parts and a persons intuitive perception about his or her own acts and their consequences. Mental models can help shape behaviour and set an approach to solving problems and doing tasks. A mental model is a kind of internal symbol or representation of external reality, hypothesized to play a major role in cognition, reasoning and decision-making. Kenneth Craik suggested in 1943 that the mind construc ...

Models of scientific inquiry

In the philosophy of science, models of scientific inquiry have two functions: first, to provide a descriptive account of how scientific inquiry is carried out in practice, and second, to provide an explanatory account of why scientific inquiry succeeds as well as it appears to do in arriving at genuine knowledge. The search for scientific knowledge ends far back into antiquity. At some point in the past, at least by the time of Aristotle, philosophers recognized that a fundamental distinction should be drawn between two kinds of scientific knowledge - roughly, knowledge that and knowledge ...

Possible world

In philosophy and logic, the concept of a possible world is used to express modal claims. The concept of possible worlds is common in contemporary philosophical discourse but has been disputed.

Process reference models

A process reference model is a model that has generic functionality and can be used more than once in different models. The creator of a process model benefits from existing process reference models by not needing to reinvent the process model but only reusing it as a starting point in creating a process model for a specific purpose.

Scientific modelling

Scientific modelling is a scientific activity, the aim of which is to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate by referencing it to existing and usually commonly accepted knowledge. It requires selecting and identifying relevant aspects of a situation in the real world and then using different types of models for different aims, such as conceptual models to better understand, operational models to operationalize, mathematical models to quantify, and graphical models to visualize the subject. Modelling is an essential and ...
