Then, for this inverse problem, several uniqueness and continuous dependence results are developed. The case of harmonic conductivities is also investigated in detail.

The amplification of such uncertainties through upward or downward transitions by a homogenisation model is emphasized and exemplified with the Mori-Tanaka model. In particular, the sensitivity to data uncertainty in the inverse determination of constituent parameters based on downward transitions is stressed on an example. Then a database improvement method, which exploits simultaneously the available information on constitutive uncertainties at all scales instead of just propagating those associated with one scale, is presented and shown to yield substantial reductions in uncertainty for both the constitutive parameters and the response of structures. The latter finding is demonstrated on two examples of structures, with significant gains in confidence obtained on both.

Starting with the positioning in the action research literature stretching to organizational development, the second stream studies the ontological and epistemological underpinning followed by the socioeconomic methodology and strategy. The third stream situates the method in the strategic management control realm. The approach builds on a literature review that yielded a theoretical positioning diagram, and proved to be a solid basis for the subsequent socioeconomic interventions in management consultancy.
