Modeling consists in defining rules of evolution for intervals of time defined over a given period, then to calculate and to reproduce this evolution.
Intervals of time and period define temporality of the model, rules are actions (agents).
Temporality
Modeling based on discrete flows is of sequential decision type emanating of actions individually planned by six temporal parameters :
- chronology, start, repeat, interval, type of cycle and filtered cycles.
The out of synch of floating cycle and circularity
are possible.The scales of time are virtual, defined for basic or floating cycle.
The model is calculated for a defined number of cycles.
Actions (agents)
There returned values modify objects, they are :
- constant, temporal array, cloud (no temporal array with double entry) and procedure.
In procedures, all needed code is permitted :
- all functions are writed with power language in French or in English in a very easy syntax, like natural language, they will be dynamically compiled.
Results analyze
During phase of calculation all results are stored in the data base of studied model.
They are then naturally displayed in the model through its elements, objects and links(pipe).
Dynamic charts and 3D or 4D objects can be encrusted in the model.
Dynamic 3D or 4D objects are created with a 3D modeller
, its permits to associate all parts
of these objects with the elements of the model to control them.The graphic user interface, intuitive and wysiwyg, permits to create, modify and analyze models.
Dynamic optimization
During phase of calculation, actions can dynamically loop temporally until obtaining the waited results. This functionality is called retro-calculation,
it permits overlaped looping, training
and thus artificial intelligence.Vectoring
Elements can be vectored by vectors made up of domains.
A subset of vectored model could thus be associated to various cases of figures.
Other vectors can be created by making the cartesian product of normal vectors.
One can thus combine up to twenty vectors, but this limit can be increased.
Charts
They represent the values of the elements over the simulated period.
3D or 4D objects
They are created using a 3D modeler; it calls primitives of the OpenGL graphic library.
Each primitive can be associated with an element of the model.
The 3D object thus created becomes 4D object. All its parameters will be vary according to the value of the elements of the model, for the current unit of time during restitution.
The primitives are assembled, repeated and separately initialized.
Equation and integrity
For any studied model and at any moment during the simulated period, the sum of the objects will remain equal to the sum of the initial dotation of this one, because the values computed by the actions are transferred between a source object and a target object.
Diachrony and synchrony
Synchrony is study of all the relations between the elements at a given time.
Diachrony is evolution of a system in time, elements by elements.
These two characteristics are possible simultaneously by the dynamic graphic restitution of the values of the elements of the model.
Collateral effects
Since the principle used is that of the dynamic balance of the systems, any variation of value of an object must be compensated, giving prominence thus obligatorily the collateral effects caused by this variation.
- creation and modification of the model
- calculation of the model
- restitution of the results

Graduated time scale
Blue cursor indicates the time corresponding to the state of the system.
Objects, rectangles
Each rectangle represents the value of an object.
They are called objects.
Actions, circles (agents)
Each circle represents the value of transfer which permit to modify objects.
They are called links of transfer and they contain planned actions.
The lines and the arrows indicate the way of the transfer.
Charts
They represent the variation of the elements over the simulated period.
4D objects
They represent in four dimensions (x,y,z,t) evolution of elements.
