Résumé (EN)

The paper begins with a succinct presentation of what OR-DA seeks to accomplish and then goes on to develop two examples. Section three, which explains why the search for robustness is a major concern in the field, details the meaning of the qualifier robust, as used in this paper. The two requirements presented in section four must be taken into consideration appropriately, if the concern is to be addressed properly. Section five deals with the framework schema wherein the standard answers to the concern can be found. The two sections before the conclusion provide an overview of less traditional approaches.Robustness for OR-DA is a subject that has given rise to many publications over the last several years. I will first present the focus of OR-DA and deal with two examples that will be developed further in my article. I will go on to explain why robustness is a major concern in OR-DA, which will lead me to underscore the two requirements that must be tackled to deal with this concern properly. Then, I will present the framework schema for most research and the way that the concept of a robust solution is usually addressed. In the sections titled “Other Ways of Defining the Concept of ‘Robust Solutions”’ and “The Concept of ‘Robust Conclusions”’, I will examine the most recent research outside the schema, with other definitions of robust solutions and other types of answers (robust conclusions).
