“…There is abundant research on interdependence extraction in negotiation [11,1]. For example, a method grouping highly interdependent issues by collecting meta-level information about the agenda in prior to the negotiation was developed and evaluated in [27]. A method was then proposed for using meta-negotiation.…”

The success of a negotiation depends largely on the actors and the negotiation domain. It is common that negotiators rely on an agenda to simplify the process and reach better deals. This is particularly the case when the preferences of the negotiators are complex and when multiple issues are at stake. Using an agenda to explore and decompose the interdependence relationships between the issues is one way to address this problem. In this paper, we propose to address this challenge by applying the classical divide-andconquer approach to automated negotiations through means of utility decomposition and bottom-up agenda construction. The approach does not impose an agenda from the top level of the negotiations, but builds it bottom-up given the individual utility functions of the agents and the relationships between the issues. Our approach reduces the cost of exploring the utility spaces of the agents and the resulting bidding processes. We implement the approach in a novel protocol called the Decomposable Alternating Offers Proto-col (DAOP). The experimental results show that our divide-and-conquer algorithm makes a positive influence on the global performance of an automated negotiation system.

“…The approach in [27] showed promising results on the effectiveness and compu-tational cost aspects. However, the process of meta-negotiation is not very intuitive comparing to real-world negotiations since the collection of meta-information and meta-negotiation cost extra time and resources.…”

“…In most complex negotiation scenarios, whether the problem under negotiation is a process, a system, or a component, it can be decomposed into a hierarchical structure using domain knowledge abstractions. A hierarchical representation for negotiation problems presented in (Zhang and Klein 2012) is summarized here. A complex negotiation system/problem S can be further decomposed as a set of subsystems (components) {S 1 , S 2 ,...,S n }, and each sub-system S i can be further decomposed as {S i1 , S i2 ,...,S in }.…”

“…Hierarchical structure, including multiple-level decomposition, is commonly used in human-design systems to reduce system management complexity. We adopt a hierarchical model for negotiation problems proposed in (Zhang and Klein 2012). In this model, the system/problem in negotiation is represented as a decomposition of a set of subsystems, which reflects the interdependency relationships among negotiation attributes (hereinafter, used interchangeably as issues): the attributes that belong to the same subsystem are highly interdependent, while the interdependency level across different sub-systems is much weaker.…”

A large number of interdependent issues in complex contract negotiation poses a significant challenge for current approaches, which becomes even more apparent when negotiation problems scale up. To address this challenge, we present a structured anytime search process with an agenda management mechanism using a hierarchical negotiation model, where agents search at various levels during the negotiation with the guidance of a mediator. This structured negotiation process increases computational efficiency, making negotiations scalable for large number of interdependent issues. To validate the contributions of our approach, 1) we developed our proposed negotiation model using a hierarchical problem structure and a constraint-based preference model for real-world applications; 2) we defined a scenario matrix to capture various characteristics of negotiation scenarios and developed a scenario generator that produces test cases according to this matrix; and 3) we performed an extensive set of experiments to study the performance of this structured negotiation protocol and the influence of different scenario parameters, and investigated the Pareto efficiency and social welfare optimality of the negotiation outcomes. The experimental result supports the hypothesis that this hierarchical negotiation approach greatly improves scalability with the complexity of the negotiation scenarios.
