의료폐기물 처리업체 최적 위치선정에 관한 사례 연구

초록

The amount of medical waste generated in South Korea has been consistently increased in the past 10 years. Although medical waste disposal companies currently in operation provide enough capacity to manage them, demand forecast shows that the disposal need will exceed the total capacity of all the disposal companies in the near future. This paper develops a facility location model considering two possible scenarios to provide alternative solutions to this problem; scenario 1 proposes constructing additional facilities given a set of candidate locations, and scenario 2 suggests expanding capacity of the existing facilities. A case study is conducted using forecasted disposal demand in year 2020 when the current disposal capacity will be insufficient. The result demonstrates that scenario 1 generates better solution than scenario 2 in terms of the total cost, where four more facilities will be built. In the case of opposition by residents near the candidate locations, scenario 2 will be able to provide the second-best solution.
