Constraints-based Negotiation using Argumentation

In this paper, we propose a framework for constraints-based negotiation using argumentation. Agents’ constraints such as budget and time constraints play a key role in determining the set of offers agents can make. An offer in our setting consists of assigning values to a set of negotiation constraints such as prices of goods and services and delivery time. To reach an agreement, agents’ constraints must be satisfied. Each offer must be supported by arguments and each agent tries to achieve an agreement using arguments to persuade the other agent to make a concession, which is a fundamental notion in negotiation. We propose a negotiation policy specifying when a concession can be made and showing when an agreement is reached. We also propose an algorithm specifying this policy and discuss its formal properties and implementation.
