In today’s worldwide competitive business environment, effective investment planning and partner selection is one of the key issues for companies which are planning investment in abroad. The purpose of study is to propose a selection system, will provide a comprehensive approach for selecting the best GSM operator for Call Center, is selling GSM operator’s prepaid minutes, investment. For this purpose, a literature review is performed about GSM. Then, extensive interviews have been carried out with authorized experts, and qualitative and quantitative decision factors have been defined for alternative regions, countries and GSM operators, which have been evaluated by using AHP respectively. Finally, by using developed evaluation formula, each alternative has been evaluated and, the best alternative GSM operator has been selected by using Goal Programming to investment, raw material cost, labor cost, profit and market share goals. In the conclusion of our study, the results have been discussed in detail and the future work is presented as well.

3. Usability: Evaluating a relationship between criteria and investment analysis according to presentation level to alternatives.
4. Representative: Evaluating a relationship between criteria and investment analysis according to importance level to alternatives.
5. 3rd Step: In this step, GSM operator evaluation criteria (GOEC) are determined according the literature review an expert interviews as shown in Table 5.

7. RECPC = Region Evaluation Criteria’s Priority Coefficients
16. When analyzing a country, not only general indicators about country, such as population, have been evaluated, but also specific factors, which are related in investment, must be evaluated.
17. To analyze a GSM company, not only general criteria has been evaluated, such as Total Subscriber, bur also investment related criteria’s, such as revenue per user, must be evaluated.
18. In investment planning and analyzing process, evaluating only regional based criteria’, can be give wrong results. Because of that, country and GSM based criteria’s must be evaluated also.As stated in research, findings are given for managers and researchers for implementation and/or further research. <br />This paper prepared with only one firm expert and their expectations. In the future more than one firm’s expert may join this methodology and therefore results should be generalized. <br />On the other hand, this study can be carried out by using Fuzzy AHP, in order to eliminate unknown parameters in strategic decision support process.<br />References<br />[1] Vural, İ.Y., 2005.
