“…MCDA was first applied in the area of operations research, but over the years, MCDA has become of great interest to other disciplines. It is widely used in resource allocation [23], telecommunication [24,25], waste management [26], marketing [27], healthcare [28], energy planning [29], manufacturing [30], business decision [31], and budgeting [32]. Inadequate economies and analytical deficiencies of previous studies on medical waste management have prompted the use of an integrated evaluation framework known as the multi-criteria decision analysis (MCDA) in recent years [4].…”

Application of Multi-Criteria Decision Approach in the Assessment of Medical Waste Management Systems in Nigeria

Globally, the pandemic of COVID-19 has penetrated all spheres of human endeavors, and noteworthy is the tremendous increase in the volume of healthcare wastes generated in Nigeria. There has been an increase in medical waste materials produced as a result of the extensive use of both disposable personal protective equipment (PPE), such as face shields and nose and face masks, and highly infectious waste materials, such as contaminated syringes, needles, and soiled bandages from diagnosed positive cases. Despite the huge volume in waste generation, a standardized evaluation framework is currently lacking in the management of medical wastes in Nigeria. This study has developed a novel assessment framework for managing medical wastes, which is curated from the technical guidelines of the World Health Organization (WHO). The applicability of the framework was examined on seven designated public and private-owned hospitals in Ota. The fuzzy analytical hierarchy process (FAHP) and analytical hierarchy process (AHP) approaches of multi-criteria decision analysis were utilized in modelling an evaluation framework for the objective of medical waste management. Carefully designed interview questionnaires, observations, and site visits were carried out to obtain data from healthcare professionals in Ota. Results show that waste segregation was practiced more decisively in private hospitals than public hospitals. Waste segregation is established as a key determinant in implementing an effective waste management system in any healthcare facility. The success of waste segregation in healthcare institutions is highly dependent on good hospital management, organizational policies, efficient budget planning for waste management, and the operational running cost. Disposal methods investigated were mostly open burning and incessant dumping for most public health care centers. Deficient waste management practices were observed in waste disposal, waste transportation, storage, and organizational policies. While the awareness and capacity building on occupational safety practices and environmental public health is widely known by health workers and waste handlers, compliance and enforcement are critical challenges. The validation of results using fuzzy TOPSIS and a sensitivity analysis shows a high degree of the consistency, stability, and robustness of the model. Findings from the present study can aid decision making, as this will benefit policy makers and key stakeholders in developing more comprehensive and effective medical waste management guidelines in Nigeria. In addition, future decision-making studies could augment the results from the current research by assessing the impact of the pandemic preparedness and response on medical waste management.

“…The stakeholders of the decision problem are the inhabitants of the town. However, to simplify the decision-making process and because we focus on the consideration of multiple periods and uncertainties, generic [18,47,64,86] or PROMETHEE-specific [87,88] group decision-making frameworks are not employed. We also adopt the same transition paths Ψ, which are described in detail in Table 2.…”

“…Multi-criteria decision analyses, especially approaches from multi-attribute decision making (MADM), which evaluate a finite and discrete number of alternatives, have been applied in combination with energy scenarios; this achieves more transparent decision support processes, helps to structure complex decision problems, and provides the basis for making informed decisions [8][9][10][11][12]. MADM approaches can provide decision support for and have long been applied in complex decision problems, such as the evaluation of sustainability, which are characterized by conflicting criteria measured in incommensurable units (see [6,[13][14][15][16][17][18]). By aggregating decision-relevant information, MADM approaches provide the basis for an analysis, comparison, and ranking of alternatives, and eventual selection of the best option.…”

Methods of multi-criteria decision making (MCDM) from operations research have been applied to provide information for making long-term decisions in the energy sector, and energy policy. For example, in sustainability evaluations, multiple conflicting criteria can be considered. While most MCDM approaches have been applied to evaluate energy systems in a single period, the multi-criteria evaluation of energy system evolution over time has received less attention. To evaluate such transition paths, multi-period MCDM approaches can be used. Because of long-term planning horizons, deep uncertainties need to be considered. Based on prior multi-period MCDM approaches, this paper provides an extension of the outranking approach preference ranking and organization method for enrichment evaluations (PROMETHEE) for multi-period evaluations in deep uncertainty settings. In order to adequately address the consideration of uncertainties and to obtain an additional level of information, a multi-period PROMETHEE approach and scenario planning are combined. In an illustrative example, this method is applied to a case study from the German energy sector regarding a renewable energy transition. This highlights the potential interactions of a multi-period perspective and the consideration of external scenarios in the decision-making process.

“…In Brazil, the Minas and Energy Ministry (MME) launched the Program for Development of Electric Energy Distribute Generation (ProGD) to broaden and deepen the actions to stimulate the energy generation by consumers themselves, based on renewable energy sources, especially solar, photovoltaic, wind, and biomass, to support and clarify energy companies investing in energy projects, which DG aggregates, both in terms of the National Agency of Electric Energy (ANEEL) [46][47][48].…”

Combining Value-Focused Thinking and PROMETHEE Techniques for Selecting a Portfolio of Distributed Energy Generation Projects in the Brazilian Electricity Sector

et al. 2021

This article aims to propose a multi-criteria model to support decision-making from a portfolio in selecting technologies for Distributed Generation of Energy (DGE) projects based on the characteristics of the geographic space in Brazil. The decision model involves using multi-criteria to support the evaluation, prioritization, and selection of projects under a multistage decision-making process that fits into a strategic management cycle within the energy sector of Mato Grosso do Sul (Brazil). The over-classification techniques Preference Ranking Organization Technique for Enrichment Evaluations (PROMETHEE) II and V were applied under the Value-Focused Thinking (VFT) approach, reflecting the decision-maker or manager preferences among several conflicting criteria in the investment context of sustainable distributed energy generation projects. Based on real data, a numerical application is employed to view the steps of this decision model and illustrate the adequacy and effectiveness in practical issues of portfolio management.
