Relativized Systemic & applications


RS, RSE and KGM developments



Her long experience of quantum physics drove M. Mugur-Schächter to discern beneath the mathematical formalism a general and systematically relativized method of building knowledge. She called this method Method of Relativized Conceptualization (MRC). Physical reality in regarded as a substratum which cannot be described on its own, but in which we act, guided by our conceptualizations and our experiences, finality driven. MRC brings to light some descriptional features that universally characterize the very first step of any knowledge building process, analyzed in terms of “transferred descriptions”. These features had remained hidden beneath languages, logical and scientific thought and especially probabilities. While we classically regard physical reality as made of persistent entities endowed with properties, these entities now emerge explicitly as the result of conceptualization processes unfolding from this very first built knowledge layer.

It follows that it should be possible to develop an MRC based approach to endow the purely qualitative concepts of Systemic with a scientific legitimacy and a specific role in a comprehensive construction that would turn them into meaningful, operational and objectifiable concepts. Contrasting with the fuzzy conceptual basis of System Engineering as it is, and its poor operational results, such a move would entail a tremendous qualitative change in our mastering of complexity to either build and organize consensual knowledge, or to design industrial artefacts.

Such has been the motivation which has steered us toward designing an MRC based methodological framework to master the facto-conceptual genesis of physically meaningful concepts, guided by a dominant goal: to get an effective control over the industrial System Engineering of embedded mechatronic devices.

Such an ambition has imposed :

These works fit into a broader perspective of general application, we can bring to mind inspired by the formula E. Schrödinger used to describe his own project :

Explicitly integrating in cognitive as well as innovative processes the active finalities which determine the framework of our conceptualization process of “the” reality, but this, without any concession to the principles of generality, of precision and of refutability which have fostered our adaptive successes, but, on the opposite, endowing them with a new basis to optimize the mastery of our destiny.

Applications field

Experimentations achieved have historically focused on two application fields: data mining and system engineering. In the first domain, the concept of relativizing point of view is generally accepted and there is no doubt as to the artifactitious nature of informational entities manipulated. On the opposite, in the second one, dominates the idea of a physical reality endowed with an organization of its own, independent from any point of view, a posture deeply rooted in our daily experience.

It comes therefore not as a surprise that Data mining applications first unfolded independently from the CeSEF epistemological word, chaired by Pr. M. Mugur-Schächter. The awareness of this work in 1998 came as an incentive to proceed and fostered the idea of extending the experimentation field to physical system engineering. In quantum physics as well as in Innovative processes, there is no preexisting entity but a constructive process to conceptualize the material support of either scattered traces in space and time or the realization of motivating finalities. This applicative transposition of an emerging logically formalized epistemology proceeded first by analogy, up to 2008, when we undertook the setting up of a mathematized framework to operationally fully benefit of the conceptual breakthrough.

Data mining

First tooled experiments were conducted by H. Boulouet from 1996 to 2004 in the aeronautical and military domain, focusing on Integrated Logistic Support and technical documentation. The stakes where to dynamically construct data consulting environments, according to different contexts, views and user’s profiles, based on a unique data repository. The applications should also make possible to construct on the fly documents conforming to national or international standards (NATO, French and German standards).

Meanwhile F. Fleuchey undertook independently, from 2004 to 2010, complementary developments. He focused on the management of technical and organizational information genesis within the automotive industries (engine control), in a renewed and broader understanding of Product Life Management (PLM) related stakes. This work has unfold within the Relativized Systemic (RS) framework since 2008. PSA engine department management stopped the project in 2010 despite users’ satisfaction, when PSA R&D management decided to develop a comprehensive project lifecycle management system relying on external resources, in connection with his decision to develop a System Engineering method based on functional analysis.

System engineering

Prototypes were developed and evaluated within the automotive industry at PSA from 2005 up to early 2011. Y. Rogard, confronted with the complexity of mechatronic system design, was looking for a new methodological framework. It led to H. Boulouet’s hiring who started the job.

These developments were operationally applied up to 2008 to car body mechatronic systems whose design was relying on common organic components, such as car doors and windows control systems, automated car body configuration according to users profiles, … These prototypes eventually relied on an RSE Integrated Development Environment (EDI) whose code was generated out of the RS formal language through the RS Software Engineering Workshop. Success made possible to get a one million funding by the French government to make public application results to testing activities. The reluctances of PSA R&D electronic department management stopped the project. Services modeling, at the vehicle level came as the new successful application field, up to 2010 when PSA R&D management decided that any System Engineering development should exclusively rely on functional analysis.


Main realizations

Data mining realizations

Within Aerospatiale (now EADS)

Starting point : (in collaboration with J.Y. Lambert) : confronted with the failure of functional analysis as a method to master the production, broadcasting and display of “complex” technical data (1995: Rafale, Apache system, technical data design environment – BEST project), introduction of the concept of “relativized view” at all the stages of the process.

Within Ligeron

Within PSA (F. Fleuchey)

System Engineering realizations

Within PSA

2006-2010 (with E. Campo, G. Hou): Design of a RS Software Workshop based on Topcased open platform and RS language using MOF (Meta Object Facilities). This workshop was used to design different RSE integrated development environments offering optimized services according to the complexity levels of the system to be designed (user HMI and automation level, documentation generation, simulation or static modeling). These IDE consisted in applications wrapping UML modeler Rhapsody from IBM.

2006-2008 (with E. Campo): design of several car body mechatronic systems using RSE IDE, each time taking independently into account different points of view whose overlapping eventually determine the specifications of shared ressources.

This work gave rise to computerize mock-ups, including abstraction levels to trace concepts against observable facts. These mock-ups made possible automated technical documentation generation (specifications). They were also used to evaluate the compliance of the realized with the expected. The full integration of safety analysis within RSE framework was undertaken with V. Brindejonc.

Methodological guidelines were elaborated by B. Massy de la Chesneraye to make the technical documentation classical writing process compliant with RSE framework.

2009-2010: computerized mock-ups used to model product services, relying on the RSE concept of biopsychic description to describe human usages. The method makes possible to describe such phenomena as habituation, sensitization, active and passive conditioning, etc.

PSA management decision in 2010 to base System Engineering on functional analysis brought RS related projects (RSE and Sonia) to a standstill.

As a result, work has proceeded on the sole theorical level.
