A Recommender System Based on Multi-Criteria Aggregation

Fomba, Soumana; Zarate, Pascale; Kilgour, Marc; … - In: International Journal of Decision Support System … 9 (2017) 4, pp. 1-15

Recommender systems aim to support decision-makers by providing decision advice. We review briefly tools of Multi-Criteria Decision Analysis (MCDA), including aggregation operators, that could be the basis for a recommender system. Then we develop a multi-criteria recommender system, STROMa...

Fuzzy Optimal Approaches to 2-P Cooperative Games

Al-Mutairi, Mubarak S. - In: International Journal of Applied Industrial Engineering … 3 (2016) 2, pp. 22-35

In game theory, two or more parties need to make decisions with fully or partially conflicting objectives. In situations where reaching a more favourable outcome depends upon cooperation between the two conflicting parties, some of the mental and subjective attitudes of the decision makers must...

Parallel Scatter Search Approach for the MinMax Regret Location Problem

Ibri, Sarah; Cherabrab, Mohammed EL Amin; Abdoune, … - In: International Journal of Applied Metaheuristic … 9 (2018) 2, pp. 1-17

In this paper we propose an efficient solving method based on a parallel scatter search algorithm that accelerates the search time to solve the minmax regret location problem. The algorithm was applied in the context of emergency management to locate emergency vehicles stations. A discrete event...

Query Frequency based View Selection

Kumar, T.V. Vijay; Haider, Mohammad - In: International Journal of Business Analytics (IJBAN) 4 (2017) 1, pp. 36-55

View selection deals with the selection of appropriate sets of views capable of improving the response times for queries while conforming to space constraints. Materializing all views is infeasible, as the number of possible views is exponential with respect to the number of dimensions and,...

Hierarchical Fuzzy Rule Interpolation and its Application for Hotels Location Selection

Jiang, Yanling; Jin, Shangzhu; Peng, Jun - In: International Journal of Cognitive Informatics and … 10 (2016) 1, pp. 55-79

Fuzzy rule interpolation offers a useful means for enhancing the robustness of fuzzy models by making inference possible in systems of only a sparse rule base. However in practical applications, as the application domain of fuzzy systems expand to more complex ones, the curse of dimensionality...
