Negotiation is used to solve more efficiently logistics and crisis management problems, among others, when at least two parties are involved in the decision process. Most of the current negotiation approaches only deal with problems concerning mono-dimensional negotiation, i.e. which only concern a single negotiation dimension, such as allocating a single task to a co-workers. But recently, some studies have been conducted on the topic of combined negotiations, in which the negotiation process concerns multiple interrelated objectives, a more realistic modeling of what occurs in real world applications. Therefore, we suggest to study the problem of multi-criteria and combined negotiation in multi-agents systems by designing a new protocol to solve some of existing negotiation problems.
This deliverable follows a previous one, a report titled “Cooperation-based Multilateral Multi-issue Negotiation for Crisis Management” (Hemaissia et al., 2006). The negotiation protocol proposed here, is suited for multiple agents with complex preferences and taking into account, at the same time, multiple interdependent issues and recommendations made by the agents to improve a proposal.
