Abstract
Deterioration of Municipal Solid Waste Incineration Plants (MSWIPs) is becoming a significant social issue in Japan, especially considering decrease of population, and some plants can be renewed or closed under some circumstances. To make a scheduling for renewal or closure of MSWIPs, we apply the multi-period multi-plant location model by Okubo et al., to the south part of Miyagi prefecture. We examine the stability of the timings and priority of renewals and/or closures against the changes in population prediction, maintenance cost of plants, reconstruction cost, and so on. As a result, under realistic parameter changes and error of population forecasting, renewal and closure strategy are very stable at least first 6 years. On the otherhand, the closure decision and timing of the MSWIPs having later year closure plan may vary due to the parameter change.
