Abstract: In recent years, because of the high potential for insurability in Turkey and the rapid improvement of insurance sector, foreign investors are interested in Turkish insurance market. Since insurability rate has reached saturation point in their countries, foreign investors tended to make investments in Turkey and start to purchase local insurance companies in Turkey. In this paper we analyze five Turkish insurance companies for a foreign investor who wants to purchase a local insurance company. For selecting the most appropriate alternative we used the extended VIKOR method which applied to determine the best feasible solution according to the selected criteria. This method was developed to solve multiple criteria decision making problems with conflicting and non-commensurable criteria, assuming that compromising is acceptable for conflict resolution. In this paper, the alternatives are evaluated according to all established criteria with the VIKOR method completely under fuzzy environment with fuzzy sets. [Copyright &y& Elsevier]

Abstract: Service sector is under pressure to deliver continuing performance and quality improvement while being customer-focused. In recent terms, there exists web based or electronic service quality (e-sq) concept. With the birth of electronic commerce, it has become important to be able to monitor and enhance e-sq. Therefore, this study will examine the e-sq concept and determine the key components of e-sq. The e-sq framework is employed by the aid of service quality (SERVQUAL) methodology as the theoretical instrument. Finally, proposed e-sq framework is illustrated with a web service performance example of healthcare sector in Turkey by using a combined multiple criteria decision making (MCDM) methodology containing fuzzy analytic hierarchy process (AHP) and fuzzy technique for order performance by similarity to ideal solution (TOPSIS). The work presented in this paper shows the applicability of the e-sq framework in explaining the complexity of aspects observed in the implementation of healthcare services via internet.
