Model Theory

https://plato.stanford.edu/entries/model-theory/

`A primeira vista, aconteceu com o conceito de “modelo” o mesmo que aconteceu com o conceito de sistemas. De repente deixaram o objeto real, o fato, para um lado e se entregaram a exercitar as abstracoes mentais sobe o fato ( Already by the late 17th century the word “model” could mean an object that shows the form, not of real-world objects, but of mathematical constructs. Leibniz boasted that he didn’t need models in order to do mathematics.)

Pode se ver isto nesta encyclopedia definindo teoria dos modelos. Ela inicia falando do que ‘e a teoria em matematica e so’ mais tarde retorna ao que realmente e’ modelo de fato.

Universal Systems Model : Academic perspective x Matrix/DNA perspective

Na area academica do ensino denominada Universal Systems Model, eles usam um diagrama:

Input > Process > Output > Feedback > Input > Process > ….

Observe que isto e’ um diagrama resumido da formula da Matrix/DNA, onde:

Input = F1

Process = F2,F3.F4,F6

Output = F7

Feedback = F7>F1

A principal diferenca e’ que a formula da Matrix/DNA se refere a sistemas naturais, os quais funcionam movidos pela forsa do ciclo vital, enquanto que a formula academica se refere a sistemas mecanicos, para maquinas ou operacoes automatizadas. Uma segunda nota, e’ a que ( como vemos no texto abaixo), os academicos se referem a ” open loop ” e “closed loops”, onde o Sistema comeca com o open loop e o component “feedback” constitui o closed loop, numa clara referencia aos estados de sistemas abertos e sistemas fechados da formula da Matrix/DNA.

The MatrixDNA as Astronomic Closed System

The MatrixDNA as Astronomic Closed System

Devo pesquisar os textos academicos desta area, assim como os nomes tecnicos da disciplina, etc.,  para buscar modos de interacao entre as duas formulas visando aplicar a formula da Matrix/DNA para otimizar a tecnologia.

Neste sentido, o primeiro passo e’ googlar ” universal systems model” e ver os itens. Iniciando, registro o link para um PDF:

Onde se inicia lendo:

Explain the universal systems model

• Explain the components of the universal systems model

• Explain systems models in the context of the systems of technology such as communication and transportation

• Explain the elements or resources of technology as inputs to systems
The universal systems model is an attempt to graphically depict processes of all sorts. Viewing something through the scheme of the universal systems model is an attempt to simplify something that is relatively complex. The model typically includes a look at system inputs, processes, and outputs for open loop systems and a fourth component, feedback, is included in systems that are perceived to be closed loops.

These are often referred to as the “resources of technology.” System Inputs • People • Information • Tools and Machines • Materials • Energy • Time • Capital

Processes vary depending on the area of endeavor. For example, one of the main processes for a manufacturing company would be secondary material processes: separating, combining, conditioning, forming, and casting. However, a communication company would be encoding, storing, retrieving, transmitting, receiving, and decoding information. Outputs generally include certain eventualities such as expected, unexpected, desirable, and undesirable. For example, a manufacturer expected to make a profit, and this is desirable. However, the company did not expect to pollute the water when it accidentally spilled chemicals onto its loading dock. This output is undesireable.

Systems experience entropy.  Entropy is the degradation of all systems whether man-made or natural.  For example, the fuel system in an automobile malfunctions over time. Systems and sub-systems are interdependent. For example, in order for the automobile’s fuel and electrical systems to work together, the engine must be correctly timed.

Component Systems of Technology
The component systems of technology are:
B. Communication Systems – Systems that change information into messages that can be transmitted.  These systems include a sender, message, receiver, and feedback.
B.  Structural Systems – Systems that use goods and materials to build structures that will resist external force, support a load, and hold each structural element in a relative position to other parts.
C.  Manufacturing Systems – Systems using materials and processes to produce usable products.
D.  Energy, Power and Transportation Systems – Systems that convert energy into mechanical, fluid, electrical, radiant, chemical, and thermal energy.
