Towards A Decision Approach For The Characterization Of Potential

This paper discusses the issue of characterization and evaluation of potential crucial knowledge in medical field. We are interested almost in medical know-how. The aim of the paper is to propose a preference model based on DRSA approach in order to characterize this kind of knowledge known as "potential crucial knowledge" which can be validated in the short or medium term and is considered provisionally realistic by an actor at least or presumed by the study men for the decision support. We reuse the method for identifying crucial knowledge already tested in the automobile field and we adopt it in the medical field. We propose to build a new decision class for potential crucial knowledge which is located between two classes: Cl1 for non crucial knowledge and Cl2 for crucial knowledge. The decision classes are ordered by preference. The characterization of the new class is established using the criteria previously used to characterize the two other classes. These criteria are measured in terms of vulnerability, role of knowledge and duration of use of the knowledge. This class has been tested in the organization of protection of motor-disabled of Sfax-Tunisia (ASHMS). The aim of this society is to take early care of a handicap affected by a cerebral palsy (IMC). This global process contains many medical examinations. In this paper, we are interested in physiotherapy examination.
