Proposal of Symbiosis ADS concept and negotiation support methods for cooperative resource allocation

We propose a conceptual system model for public infrastructure systems, the Symbiosis-Autonomous Decentralized System (Symbiosis-ADS) and negotiation support methods. In this conceptual model, each agent system is owned by an individual stakeholder in a city, including individual residents or companies, and operates autonomously depending on the owner's decisions. These agent systems disclose information about their resource consumption and supply to other agents. An agent that has over consumed (resource shortage) and another agent that has under consumed (resource surplus) communicate and make an agreement, then one gives or lends resources to the other (accommodation). For this conceptual model, we developed negotiation and planning methods for supporting each agent's and owners' decision making by minimizing the negative effect of information incompleteness and environmental uncertainty. With a prototype system and simulation, we evaluated the effectiveness of these negotiation methods in a situation with information incompleteness.
