Constraint based modelling as a mean to link dialectical thinking and corporate data. Application to the Design of Experiments

Problem solving is a key activity for any innovative company. As the dialectical approach has shown its efficiency in problem solving, the starting point of our work is the use of contradiction in problem formulation stage. In this article, we analyse the possibility to use information brought by a Design of Experiments (DoE) to formulate a contradiction. Constraint Satisfaction Problem is employed to present information brought by the DoE. To use the dialectical approach, we define the concept of the Generalised Contradiction (GC). In the framework of DoE data, we show how to formulate a GC, and propose an algorithm able to identify OTSM-TRIZ System of Contradictions. Results and perspectives are discussed.
