Disasters can produce a substantial amount of waste that can threaten the capacity of waste management systems. This paper presents a methodology for estimating waste accumulation caused by disasters considering the uncertainty of the timing and scale of disasters that can be used to estimate the return period and the reliability of the disaster waste management system. To estimate the reliability of the system, the first-order second-moment reliability assessment method, in which the reliability index () is used to judge the reliability of a system, is applied in this paper. In addition, two case studies illustrate how the methods can be applied to the real world. The reliability index curve of the system developed from sensitivity analysis can provide information for decision-makers in terms of disaster waste clean-up arrangements. The approach developed can be used to analyze the effects of different parameters involved in the waste clean-up system after disasters.
