چکیده
A review of the supplier choice literature revealed that the locations and financial positions of the companies are among the most important elements in the supplier selection decisions (Stadtler, 2005). Therefore, distance between buyer and potential suppliers was selected as one input variable. Number of employees is the other input variable that is used as a proxy for the financial position of the suppliers. In other words, suppliers with higher number of employees are considered to have a better financial position in a given industry. Although this assumption could be doubtful in a study with highly aggregate industry classification, this does seem reasonable for this study with a fairly disaggregate six-digit NAICS. The only output variable, however, is likelihood of partnership.
