Abstract

e-Learning platforms are of a great help in teaching and learning fields given their ability to improve training activity quality. Subsequently, several e-Learning systems have been developed in many domains. The diversity of such platforms in a single field makes it arduous to select the optimal platform in terms of tools and services that meet users’ requirements. Therefore, we propose in this paper a ranking approach of e-Learning platforms relying on symbolic values, borrowed from the Qualitative Weight and Sum method (QWS) (Stufflebeam, 1994), preference relations and aggregating operators providing a total order among the considered e-Learning platforms.

  9. 3. pre f Max is idempotent iff ?a ? S : pre f Max(a, a) = a. From the main diagonal of table 3, we conclude that pre f Max is idempotent.
  10. 4. pre f Max has 0 as neutral element iff ?a ? S : pre f Max(a, 0) = a. Table 3 shows that pre f Max has 0 as neutral element.
  11. 5. pre f Max has E as absorbent element iff ?a ? S : pre f Max(a, E) = E. Table 3 also shows that pre f Max has E as absorbent element.
  12. 1. pre f Min is associative on S : ?a, b, c ? S : pre f Min(pre f Min(a, b), c) = pre f Min(a, pre f Min(b, c)). We denote by I the left term Pre f Min(Pre f Min(a, b), c) and by II the right term Pre f Min(a, Pre f Min(b, c)). Table 10 shows results of evaluation of the left and the right terms, which are identical. Therefore pre f Min is associative.
  13. 5. pre f Min has 0 as absorbent element iff ?a ? S : pre f Min(a, E) = E. Table 3 also shows that pre f Min has 0 as absorbent element.
