In response to requests for wide-area treatment plans that promote restrictions on plant location and energy recovery such as power generation and heat utilization, it is necessary to construct a comprehensive evaluation system that expands collection and transportation within the waste management field. However, the conventional Grid City Model that has been used for the evaluation of collection and transportation has non-linearity, rendering it unable to respond to simulation of wide-area and energy recovery. It has also been difficult to evaluate regional characteristics. We therefore worked to construct a model that can be applied over a wide area and addresses regional characteristics through a process of manageable calculations. In this study, we develop a modified model for improving the conventional Grid City Model :. With Aichi Prefecture as the target site, our results advocated optimization for transportation and a multi-regression model for collection. The collection and transportation models must be constructed to calculate and evaluate costs and carbon dioxide emissions from the entire process using public statistics. As a result, we were able to successfully develop a reproducible regression Grid City model, a linear collection-transportation model, and a model that can evaluate the cost, CO2 emissions, regional characteristics, and collection time per staff member.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
