“…By applying the procedure of QoS selection described in Section 3.4 we are able to propose a service among those three that minimizes the response time for the considered time window. The calculated values of the index (7) are quite close, as C 1 = 0.9, C 2 = 0.81, C 3 = 0.86, but selection is still possible. Service 1 is chosen as it covers at most the client's requirement.…”

“…Thus, part of the effort is directed to accounting for the existing uncertainties. The recently introduced approaches to software service quality estimation combine the two concepts of uncertainty -probability and fuzzy description -that ensure power and a well-grounded frame for assessment [1,2,6,7].…”

The paper presents an approach to QoS selection of webservices. It introduces a theoretical frame and respective applicableselection procedures, in which the solution accounts for the uncertainty ofthe existing metrics data and client preference. Methods of two generalcases are revealed in detail. The first method considers a selection basedon one service quality. The second method assesses the integrated QoS ofinteresting properties. The theoretical analysis is validated throughexperimental investigation of real data of services’ quality metrics.ACM Computing Classification System (1998): H.3.7, K.3.1.* The author acknowledges the financial support of the National Science Fund, BulgarianMinistry of Education and Science, under project grant DN 02/11 and the Science Fund ofthe St. Kliment Ohridski University of Sofia under project grant No 80-10-196/24.04.2017.
