Assisting negotiations and supporting decisions in small e-business

A lot of current small businesses involve very simple interaction models that are being formalized for carrying out electronic commerce via open networks, like the Internet, or closed, private networks. E-commerce implies carry on negotiation between suppliers and customers, and makes a decision. We develop a technique for multi-issue negotiations in competitive environments in which many sellers negotiate with one agent buyer who has to make a decision. The technique leads the negotiation carrying out comparison-based analysis of multi-options provided for sellers and gains relevant information about each option. Moreover, an algorithm is developed to support buyer's decision based on that acquired information.
