Dynamic Multi-Agent Based Variety Formation and Steering in Mass Customization

Large product variety in mass customization involves a high internal complexity level inside a company’s operations, as well as a high external complexity level from a customer’s perspective. To cope with both complexity problems, an information system based on agent technology is able to be identified as a suitable solution approach. The mass customized products are assumed to be based on a modular architecture and each module variant is associated with an autonomous rational agent. Agents have to compete with each other in order to join coalitions representing salable product variants which suit real customers’ requirements. The negotiation process is based on a market mechanism supported by the target costing concept and a Dutch auction. Furthermore, in order to integrate the multi-agent system in the existing information system landscape of the mass customizer, a technical architecture is proposed and a scenario depicting the main communication steps is specified.Product Configuration, Mass Customization, Variety Formation and Steering, Multi Agent System

Diffusion of shared goods in consumer coalitions. An agent-based model

This paper focuses on the process of coalition formation conditioning the common decision to adopt a shared good, which cannot be afforded by an average single consumer and whose use cannot be exhausted by any single consumer. An agent based model is developed to study the interplay between these two processes: coalition formation and diffusion of shared goods. Coalition formation is modelled in an evolutionary game theoretic setting, while adoption uses elements from both the Bass and the threshold models. Coalitions formation sets the conditions for adoption, while diffusion influences the consequent formation of coalitions. Results show that both coalitions and diffusion are subject to network effects and have an impact on the information flow though the population of consumers. Large coalitions are preferred over small ones since individual cost is lower, although it increases if higher quantities are purchased collectively. The paper concludes by connecting the model conceptualisation to the on-going discussion of diffusion of sustainable goods, discussing related policy implications

A Multi-Agent Method for Forming and Dynamic Restructuring of Pareto Optimal Coalitions

International audienceThe first part of this paper presents a coalition formation method for multi-agent systems which finds a Pareto optimal solution without aggregating the preferences of the agents. This protocol is adapted to problems requiring coordination by coalition formation, where it is undesirable, or not possible, to aggregate the preferences of the agents. The second part proposes an extension of this method enabling dynamic restructuring of coalitions when changes occur in the system

Exploiting simple corporate memory in iterative coalition games

Amongst the challenging problems that must be addressed in order to create increasingly automated electronic commerce systems are those which involve forming coalitions of agents to exploit a particular market opportunity. Furthermore economic systems are normally continuous dynamic systems generating many instances of the same or similar problems (the regular calls for tender, regular emergence of new markets etc.).The work described in this paper explores how simple forms of memory can be exploited by agents over time to guide decision making in iterative sequences of coalition formation problems enabling them to build up social knowledge in order to improve their own utility and the ability of the population to produce increasingly well suited coalitions for a simple call-for-tender economy.Postprint (published version

Introduction & Coda, Multi-Party Dispute Resolution, Democracy and Decision Making: Vol. II of Complex Dispute Resolution

The Complex Dispute Resolution series collects essays on the development of foundational dispute resolution theory and practice and its application to increasingly more complex settings of conflicts in the world, including multi-party and multi-issue decision making, negotiations in political policy formation and governance, and international conflict resolution. Each volume contains an original introduction by the editor, which explores the key issues in the field. All three volumes feature essays which span an interdisciplinary range of fields, law, political science, game theory, decision science, economics, social and cognitive psychology, sociology and anthropology and consider issues in the uses of informal and private processes, as well as more formal and public processes. The essays question whether the development of universal theoretical insights about conflict resolution is possible with variable numbers of parties and issues and in multi-cultural and multi-jural settings. Each volume also presents a coda, summarizing key issues in the field and suggesting further avenues for research. The second volume (and the introductory essay here) applies the theoretical foundations and practices of primary processes in dispute resolution–negotiation, mediation, arbitration and some hybrid processes in both public and private, informal and formal settings to more complex multi-party and multi issue settings, and asks whether foundational theories must be altered when there are more parties and issues. What difference do larger numbers make in theory and practice of dispute resolution and decision making? Other theoretical and empirical observations of the role of third party neutrals and facilitators in multi-party settings are explored, and applied disciplines such as game theory and decision sciences are applied to complex dispute resolution settings. Illustrations of uses of these processes in different substantive areas, e.g. legal disputes, public policy decision making, politics and governance, environmental matters, institutional relations, and high conflict settings are provided. The volume collects classic articles in multi-party, multi-issue theory and practice while interrogating the issues of how the numbers of parties and issues, different contexts and cultures challenges our efforts to create generalizable theory and practice of human conflict resolution. The review essay also discusses recent efforts to seek correspondences and learning from application of conflict resolution theory and practice to the work on deliberative democracy and political decision making. The coda suggests avenues for future research. Some attention is paid to issues of ethics and political theory, as well as evaluation of efficacy, in the use of third party facilitators in public policy and governance disputes
