Abstract

The paper proposes a new approach for tackling the uncertainty and imprecision in outsourcing and evaluating Information Technology services. Identifying suitable outsourcing options, evaluating them and choosing the best one are regarded as multiple decision criteria decision making problems under uncertainty, where the imprecise decision-maker’s judgments are represented as fuzzy numbers. A fuzzy modification of the Analytic Hierarchy Process is applied as an evaluation technique. Unlike the known fuzzy prioritization techniques, the proposed method derives crisp weights from consistent and inconsistent fuzzy comparison matrices, which eliminates the need of additional aggregation and ranking procedures. A detailed numerical example, illustrating the application of our approach to outsourcing evaluation and selection is given.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
