SIMULATION OF A RECURRENT ARCHITECTURE NETWORK BASED CIRCULATION SOCIETY

To conserve natural resources and reduce CO2 emissions, the authors developed a simulation system for an artificial society in which resources are circulated. Furthermore, parameters for the recycling and reuse of structural members were considered. An artificial circulation type of society is developed based on a concept of a recurrent architecture network proposed previously by the authors. This artificial society is described by a multi-agent model comprising the following agents: users, a builder, a blast furnace steelmaker, an electric furnace steelmaker, a reuse manufacturer with a stockyard, and a waste disposer. Objective structures are assumed to be steel structures, and steel members are traded among employed agents. Simulations are performed under different parameters such as the used steel collection rates, the steel recycling yield, and reused steel relevance ratios. Effects of such parameters on resource conservation and reduction of CO2 emissions are discussed based on simulation results.
