The purpose of this work is to give a decision support to meet requirements in competencies management. We assume that the building, the development, and the use of each competency need the concurrence of different kinds of interactions in the real work situation. The competency characteristics can be evaluated by an expert within an analysis of work situation, to get an interpretation of these...

This paper provides a Fuzzy based decision support system (DSS) for risk analysis in E-tourism ( Electronic Tourism ) investment. In general term, E-tourism is the use of information and communication technology (ICT) in tourism which may allow operating tourism in least variable cost, least time and increased work efficiency. It is worth noting that there are many factors that affect the deve...

Intensive Care Unit (ICU) medical processes can be so complex and unpredictable that physicians sometimes must make decisions based on perception. Both decision support system and Intuitionistic Fuzzy Logic (IFL) techniques can assist doctors to handle this complexity in a safe, harmless and efficient manner. To this end, we propose a prototype called Medical Intuitionistic Fuzzy Expert Decisio...

The present report further investigates the multi-criteria decision making tool named Fuzzy Compromise Programming. Comparison of different fuzzy set ranking methods (required for processing fuzzy information) is performed. A complete sensitivity analysis concerning decision maker’s risk preferences was carried out for three water resources systems, and compromise solutions identified. Then, a ...

Complexities of geological processes portrayed as certain feature in a map (e.g., faults) are natural sources of uncertainties in decision-making for exploration of mineral deposits. Besides natural sources of uncertainties, knowledge-driven (e.g., fuzzy logic) mineral prospectivity mapping (MPM) is also plagued and incurs further uncertainty in subjective judgment of analyst when there is no r...

The success of an industry depends on optimization of product cost and for achieving above goal supplier selection should be error free and efficient. The supplier selection Problem is a multi objective problem involving both qualitative and quantitative factors. These factors and their interdependencies make the problem highly complex one. The supplier selection issue has been founded out as o...

This study presents an integration of fuzzy sets theory with analytic hierarchy process (AHP) to model landslide hazard. The approach involves developing expert knowledge from existing landslide datasets which are used for standardizing digital terrain attributes, a pairwise comparison method for the elicitation of attribute weights, and their subsequent aggregation through weighted linear comb...

In this paper we present a method for early identification of students who would have serious difficulties in studying a particular subject due to lack of preliminary knowledge. Methods from formal concept analysis are applied for finding relationships between results from a test on students’ preliminary knowledge and the outcome of learning new knowledge within the same subject. Fuzzy logic ru...
