Definition.A technical system is a structured whole of functions technical and intended to meet a felt need.
History of the Engineerings.
This concept is closely related to the history of the man since the time of the first tools. The models of description of these systems also evolved/moved with the centuries growing rich with the fur and measurements by the state of the art by the moment. It is thus naturally that the Mécanique was essential a long time like the engineering. Even if since the first quarter of the XXe century, the electricity joined the constitution of the systems until becoming itself an engineering, mechanics forever been able to be put at the variation would be only by the material existence of the components and the reality of the problem of manufacture. The electronic then the Informatique is, in their turns, distinguished and taken an undeniable place in the products of the daily life.
The engineerings thus draw from the whole of the scientific knowledge of the moment (mathematical, physical but also biology, economy, sociology) and compose their own Modèles (technology) constantly updated. The standardization, often imposed by industry, also influences its models.
Today the Engineerings are exempted under this name as a Discipline from the College in School of Engineers.
Life cycle of a product
Stage in the life of a technical system, concepts and associated tools of representation. epuis
- design: diagram, plan, models of calculation
- production: plans, contracts of phase
- distribution: market research, competition, publicity
- use: note, diagram
- maintenance: SAV, spare parts.
- destruction and recycling: sustainable development
Models of representation of a system pluritechnic.
With share the ball point pen, and the medecine-chest, it has there no more entirely mechanical systems. Even the toilets concern high technology. The design of such systems proves often complex, requiring new tools of description or decision.
