Daily Waste Collection at Local Autonomous Entity : Strategizing Using Reverse Logistics Network

In this paper, we propose an efficient methodology of daily waste collection at a local autonomous entity using reverse logistics (RL) network. Currently, five district offices (Dong-gu, Nam-gu, Buk-gu, Seo-gu, Gwangsan-gu) at the local autonomous entity are treating their daily wastes by using a RL network. However, the current practice reflected inefficiency of network operation and the necessity of integration of each RL network. Therefore, we propose a revised method through a mathematical model for improving efficiency and integration. In conducting the case study, various real-life data for comparing each method were used. Various analyses and comparisons including sensitivity analysis were performed. Finally, we prove that our proposed method is more efficient than the current method.
