The focus of the paper is on the travel scene depicted on the funerary stele of L. Blassius Nigellio (CIL III 1650), a speculator of legio VII Claudia, from Viminacium. Seeking to gain a more comprehensive understanding of this scene from the everyday professional life of a Roman speculator, it draws attention to an iconographic pattern shared by a group of monuments of Roman principales (speculatores, frumentarii, beneficiarii consularis) among which the scene from Viminacium holds a very important place. It also takes a look at the origin and social status of the Upper Moesian speculator who could afford such a costly tombstone.

By using the methods of multi-criteria analysis it is possible to make decisions which have significant influence on companies' business. The aim of this paper is to evaluate different suppliers using the integrated model that recognizes a combination of fuzzy AHP (Analytical Hierarchy Process) and the COPRAS method. Based on six criteria, the expert team was formed to compare them, so determination of their significance is being done with fuzzy AHP method. Expert team also compares suppliers according to each criterion and on the base of triangular fuzzy numbers. Based on their inputs, COPRAS method is used to estimate potential solutions. Suggested model accomplishes certain advantages in comparison with previously used traditional models which were used to make decisions about evaluation and choice of supplier. It is vital to make the right decision when selecting a supplier, because the optimal choice ensures lower cost and higher quality of the product itself, and therefore more competitiveness in the market.
