A Hybrid Multi-Criteria Analysis Model for Solving the Facility Location–Allocation Problem: A Case Study of Infectious Waste Disposal

Abstract

Choosing locations for infectious waste disposal (IWD) is one of the most significant issues in hazardous waste management due to the risk imposed on the environment and human life. This risk can be the result of an undesirable location of IWD facilities. In this study a hybrid multi-criteria analysis (Hybrid MCA) model for solving the facility location-allocation (FLA) problem for IWD was developed by combining two objectives: total cost minimization and weight maximization. Based on an actual case of forty-seven hospitals and three candidate municipalities in the northeastern region of Thailand, first, the Fuzzy AHP and Fuzzy TOPSIS techniques were integrated to determine the closeness of the coefficient weights of each candidate municipality. After that, these weights were converted to weighting factors and then these factors were taken into the objective function of the FLA model. The results showed that the Hybrid MCA model can help decision makers to locate disposal centers, hospitals and incinerator size simultaneously. Besides that the model can be extended by incorporating additional selection criteria/objectives. Therefore, it is believed that it can also be useful for addressing other complex problems.

A Soft‐Path Solution to Risk Reduction by Modeling Medical Waste Disposal Center Location‐Allocation Optimization

“…First, the total designed daily disposal capacity of the selected MWDCs is assumed to exceed the sum of the maximal values of the fuzzy random daily generated medical wastes from all the medical institutions. Actually, in the literature, most of the medical waste disposal facility location‐allocation models used a similar total capacity constraint (Wichapa & Khokhajaikiat, 2017, 2018). However, in real systems, this may not always be economically viable due to the high operational cost with a relatively high designed daily disposal capacity.…”

“…So far, regarding soft‐path solutions, some studies have been carried out that discuss solid waste disposal site selection and location routing. To optimize the location selection of waste disposal centers, multiobjective mathematical models were widely used to solve the municipal solid, industrial hazardous, and infectious waste location‐routing problems under the influence of various factors such as physical, social, and demographic aspects in a city (Alumur & Kara, 2007; Asefi et al, 2015; Ghezavati & Morakabatchian, 2015; Samanlioglu, 2013; Yu & Solvang, 2016; Wichapa & Khokhajaikiat, 2017, 2018). These studies have significantly improved location identification, evaluation and selection for solid, hazardous, and infectious waste.…”

Selection of the optimal medical waste incineration facility location: A challenge of medical waste risk management

“…These are the reasons why this paper emphasizes adequate MWM, which involves solving the optimal location, routing and scheduling problems of MW collection, and incineration, as it is shown as good practice in other countries [33][34][35][36][37][38][39][40][41][42][43] . This is especially significant today when authors like Yu, Sun, Solvang, and Zhao 44 prove the importance of MW and optimization as one of the key tools in searching for possible solutions during the COVID-19 pandemic.…”

Location of Hospital Waste Disposal Site With FSWARA-GIS-MAIRCA Hybrid Algorithm

“…Ebadi Torkayesh et al(2019) used the entropy, fuzzy VIKOR, and ELECTRE techniqu to analzye municipal solid waste in Azerbaijan, Iran. Wichapa & Khokhajaikiat(2018) used Fuzzy AHP and Fuzzy TOPSIS algorithm to determine the weight of selected criteria in the management of hospital infectious waste. Midatana et.al(2018) used the hybrid method of AHP, TOPSIS, and GIS to evalaute and determine the asppropriate location for the construction of industrial centers.…”
