Location of Infectious Waste Incinerator of the Hospital in Maha Sarakham Province
This research aims to develop mathematical model for locating the infectious waste incinerator for 13 hospitals in Maha Sarakham province. Mathematical model was developed as a Goal Programming with three goals, minimizing the total cost, minimizing the total distance between hospitals and the location of infectious waste incinerator, and minimizing the number of location of infectious waste incinerator. This mathematical model was solved by LINGO. The result showed that there were two locations of infectious waste incinerator in Mahasarakham hospital and Nadun hospital with capacity of 1,200 and 400 kg/day, respectively. The total cost is minimized to 16,108 baht/day. Additionally, infectious waste was transported from Mahasarakham hospital, Borabue hospital, Kosum Phisai hospital, Chiang Yuen hospital, Kae Dam hospital, Kantharawichai hospital, Kut Rang hospital, and Chuenchom hospital to incinerator located in Mahasarakham hospital, with the total amount of 1,030.11 kg/day. Moreover, infectious waste was transported from Nadun hospital, Phayakkhaphum Phisai hospital, Wapi Pathum hospital, Na Chueak hospital, and Yang Si Surat hospital to incinerator located in Nadun hospital, with the total amount of 180.17 kg/day.
