The outsourcing of information systems can not only reduce installation cost, but also allow a company to focus more on its core competence. Being sure of selecting the best contractor can increase the likelihood that information system outsourcing will be a success. This study uses the fuzzy concept to develop a decision support system which can help decision-maker to get a better judgement and with the explanations for the result. Via implementing this system, we not only can select the best one contractor among the outsourcing information service companies, but also the information service companies can assess themselves to adjust or improve the caused factors if the aggregative capability does not meet the needs.
