- Objectives of the presentation -
• Define the key elements of EMR
• Define the fudamental rules – For connecting elements – For solving conflicts of associations
• Define the notions of – Action, reaction and tuning paths
• Assumption – As EMR is an intermediary step, coming after a modeling activity, one will
consider that models are already defined…

- Accumulation elements -
• Back to definitions – System: interconnected subsystems organized for a common objective, in
interaction with its environment. – Input: produced by a subsystem, imposed to its close subsystem – Output: consequence of the subsystem evolution, imposed to its close
subsystems – Interaction principle: each action induces a reaction – Internal accumulation of energy (with or without losses)
• Key transformation for safety and efficiency • Output(s) is an integral function of input(s), delayer fron input(s) changes • Causal description: fixes input(s) and output(s)
– Needs in defining an element representing the accumulation of energy, and the links with its close subsystems
• According to a causal description, and to the interaction principle

• Remain – The property of a non causal element to permute inputs and outputs can be
efficiently used • I/Os of a non causal element are fixed by state variables (accumulation
element), does not necessarily solve conflicts of associations • In case conflicts of association subsist

Seminar Sept. 2014 “Energetic Macroscopic Representation”
« Conclusion » EMR = multi-physical graphical description based on the interaction principle (systemic)
and the causality principle (energy)
Basic elements = energetic function sources, accumulation, conversion and distribution of energy
Association rules = holistic property of systemic enable keeping physical causality in association conflict
Applications analysis, design, simulation, control structure…
