During an interaction between several software entities trying to solve a problem, two kinds of attitudes can occur: cooperation if all entities have the same goal, negotiation if self-interests are in conflict. Cooperation has largely been studied, whereas the later has not really been computationally studied. In this paper, we define a generic agent state model and a generic protocol for contract negotiations, called ANTS, and we propose a three-level methodology to build generic negotiation applications based on a communication protocol, a generic internal structuration for problem representation and a strategy level to obtain better rationality. Before comparing our approach with other researches on the same topic, we give an example of application of this work to solve a concrete virtual market problem and another exemple of application for appointment taking. The aim of this paper is to show that it is possible to describe precisely a generic model that we can use in several negotiation and marketplace problems. These researches on negotiation take place in software engineering works for artificial intelligence and multi-agent systems.
