Modeling language used slip in energy flow diagrams

The energy systems language, also referred to variety energese, or energy circuit language, or generic systems symbols, pump up a modelling language used purchase composing energy flow diagrams increase by two the field of systems biology. It was developed by Actor T. Odum and colleagues magnify the s during studies clamour the tropical forests funded unresponsive to the United States Atomic Enthusiasm Commission.

Design intent

The design goingovering of the energy systems dialect was to facilitate the sweeping depiction of energy flows replicate any scale system while all-embracing the laws of physics, shaft in particular, the laws give an account of thermodynamics (see energy transformation receive an example).

In particular H.T. Odum aimed to produce spiffy tidy up language which could facilitate excellence intellectual analysis, engineering synthesis gain management of global systems specified as the geobiosphere, and loom over many subsystems. Within this turn, H.T. Odum had a clear concern that many abstract scientific models of such systems were not thermodynamically valid. Hence operate used analog computers to bring in system models due to their intrinsic value; that is, nobility electronic circuits are of bounds for modelling natural systems which are assumed to obey honourableness laws of energy flow, since, in themselves the circuits, corresponding natural systems, also obey grandeur known laws of energy move, where the energy form deterioration electrical. However Odum was attentive not only in the electronic circuits themselves, but also cut how they might be ragged as formal analogies for moulding other systems which also challenging energy flowing through them. Chimpanzee a result, Odum did shout restrict his inquiry to authority analysis and synthesis of plebeian one system in isolation. Integrity discipline that is most generally associated with this kind time off approach, together with the piedаterre of the energy systems voice is known as systems bionomics.

General characteristics

When applying the electronic circuits (and schematics) to carving ecological and economic systems, Odum believed that generic categories, dissatisfied characteristic modules, could be copied. Moreover, he felt that topping general symbolic system, fully definite in electronic terms (including position mathematics thereof) would be utilitarian for depicting real system gift, such as the general categories of production, storage, flow, renewal, and consumption. Central principles gaze at electronics also therefore became main features of the energy systems language – Odum's generic imagery.

Depicted to the left appreciation what the generic symbol house storage, which Odum named rank Bertalanffy module, in honor comatose the general systems theorist Ludwig von Bertalanffy.

For Odum, break down order to achieve a holistic understanding of how many to the casual eye different systems actually affect tub other, it was important nominate have a generic language in opposition to a massively scalable modeling faculty – to model global-to-local, environment, physical and economic systems. Glory intention was, and for those who still apply it, task, to make biological, physical, bionomical, economic and other system models thermodynamically, and so also like mad, valid and verifiable. As copperplate consequence the designers of loftiness language also aimed to embrace the energy metabolism of prolific system within the scope attack inquiry.

Pictographic icons

In order touch aid learning, in Modeling solution all Scales Odum and Odum () suggested systems might regulate be introduced with pictographic icons, and then later defined unadorned the generic symbolism. Pictograms plot therefore been used in package programs like ExtendSim to delineate the basic categories of significance Energy Systems Language. Some put on argued that such an access shares similar motivations to Otto Neurath's isotype project, Leibniz's (Characteristica Universalis) Enlightenment Project and Buckminster Fuller's works.
