Byline: Panayiotis Tahinakis, Dimitrios Ginoglou, Nikolaos Protogeros The growth and expansion of firms into foreign markets have resulted in the aggregation of financial information that includes non-homogeneous elements. This paper seeks to investigate the difficulties of reporting on segments of a business. Emphasis will be laid on analysing the existing accounting recognition and measurement difficulties deriving from reporting research and development (R&D) expenditures in the light of investment decisions by the Greek banking sector. In conclusion, this study indicates that there are accounting and auditing problems of defined, measured and disclosed R&D to users of financial statements. Despite these difficulties, the importance of R&D expenditures will increase, as the capital market grows and there is a constant need to supply reliable accounting information.

The purpose is to solve the optimisation problem, taking into account constraints such as the salesmen capacity and income increase in a uniform way and the company's turnover increase. In this approach a sales schedule is developed dynamically by all of the concerned participants. The negotiation methodology used allows agents to negotiate with other agents in a certain geographical area based on their sales capacity, commission percentage and the area's sales turnover. A simulation model based on Repast3 has been developed to evaluate the algorithm accuracy and the system's convergence. By executing this prototype with various utility functions, interesting results have been achieved showing a convergence in total company's turnover, salesmen capacity and salesman income.
