A fuzzy based matrix methodology for evaluation and ranking of data warehouse conceptual models metrics

الملخص EN

The authors present a methodology for ranking data warehouse conceptual models metrics based on opinion of experts using fuzzy inference technique.

The fuzzy based approach gives a precise ranking methodology due to its ability to handle imprecise data involved ranking of metrics and ambiguity involved in expert decision making process.

The proposed work aims towards ranking of quality metrics already proposed and validated by Manuel Serrano along certain identified parameters based on expert opinion and evaluation of criteria matrix using permanent function.

The results obtained are also compared with the actual experts ranking.

The achieved results are better as the imprecise human thinking is taken into consideration during calculation of results to give realistic results
