This thesis develops a demanufacturing system modeling and simulation tool as an interface between simulation methods and demanufacturers. This tool can mimic the behavior of demanufacturing facility and obtain penetrable understanding of the system. By this modeling tool, one can intuitively analyze the behavior of a system and improve the operational efficiency. Detailed designs on the simulation tool including user interface, logic, and user view are presented in this thesis. The initial prototype version of the system modeling and simulation tool has been completed with fourteen modules in the developed template. Each object in the template refers to a specific demanufacturing activity and uses detailed simulation logic behind its design to perform that activity.

The application to an electronic demanufacturing facility illustrates the usefulness of the interface to manage and improve the overall efficiency of facilities. This thesis also applies the simulation tool to a typical demanufacturing facility. Relevant system performance is analyzed. The comparison of different operational scenarios is made and the suggestion for better options of the system is discussed. This work is useful to assist designers in the design of efficient demanufacturing systems to tackle the environmental problems that may be caused by retired or faulty products.
