Abstract

Multiparty agreements often arise in a multiagent system where autonomous agents interact with each other to achieve a global goal. Multiparty agreements are traditionally represented by messaging protocols or event- condition-action rule sets in which agents exchange messages in a predefined sequence to ensure both global and local consistencies. However, these models do not readily incorporate agents' autonomy and heterogeneity, which limits their ability to help build a flexible open system. Commitments have been studied for modelling various agent interactions. This paper introduces commitments as the key elements in formulating multiparty agreements. Our model focuses on how agents may negotiate with each other to build a mutual agreement based on their individual constraints. The actual execution sequence is validated by checking the compliance of commitment casual relations. Our approach is geared toward constructing business processes where agents are mutually constrained in a manner that preserves their autonomy and heterogeneity.
