“…The hybrid fuzzy‐Delphi‐AHP‐DEMATEL approach has been used for the following reasons: first, selecting the evaluation criteria for sustainable HCWM is MCDM, which involves subjective judgments, perceptions, qualitative inputs, and vague information. Hence, to handle this imprecision, literature has proposed a fuzzy set theory (Goyal & Kaushal, 2018; Kharat et al, 2016). Second, fuzzy‐Delphi can scrutinize the identified criteria by considering the stakeholders' preferences in real‐life situations, which cannot be given in terms of crisp values (Hsu et al, 2008).…”

Healthcare waste management (HCWM) has become the most concerned issue for hospitals to enhance their environmental performance while reducing the waste disposal costs. The present study aims to standardize the evaluation criteria for the stakeholders to ensure sustainable environmental development by safe disposal of infectious healthcare waste (HCW). The present study applied the fuzzy‐Delphi method to scrutinize the criteria identified from the literature and experts' opinions and resulted in 20 subcriteria under the following six main dimensions: experience, relationship, environmental factors, technology and qualification, economic factors, and firm's capabilities. Further, this study proposed a hybrid approach based on analytic hierarchy process (AHP) and decision‐making trial and evaluation laboratory (DEMATEL) under fuzzy environment to analyze the importance and interrelationships of these listed criteria. The study also showed that the experts have given approximately 70% weightage to three main criteria: firms' capabilities, economic factors, and technology and qualification. The implications of the study would help the healthcare administration and Pollution Control Boards to prepare check sheets for recording HCWM practices and, hence, contribute to sustainable environmental development in an efficient way. Understanding the prioritized cause‐group criteria would further protect hospitals' environment from the spread of infection caused by the HCW in the long run.

“…The basic idea of Analytic Hierarchy Process (AHP) is to construct the problem hierarchically according to the goal of decision-making (as shown in figure 2). The target level is the highest one, the middle level is the criterion level, and the bottom level is the solution level [8,9].…”

Considering the deepening of electric power market reform, it is urgent to analyze the operation efficiency of the full voltage level of provincial power grids, of different cities. And then, to seek the cities with lower operation efficiency, which will give guidance to the accurate investment of power grids and enhance the comprehensive investment benefits. This paper established an evaluation model of full voltage level operation efficiency of provincial power grid, and an evaluation index system of sub-voltage level operation efficiency of provincial power grid. Using analytic hierarchy process (AHP), the weights of evaluation indexes have been determined, and the evaluation results of power grid operation efficiency in different cities have been obtained. Finally, according to the scores, the cities with low operation efficiency were determined, and the specific indices of the cities with low operation efficiency were analyzed to guide the investment planning of the power grid. Keywords-analytic hierarchy process (AHP); electric power grids; operation efficiency; investment planning I.

“…The basic idea of the AHP is to build the problem hierarchically based on the decision goal (as is shown in Figure 4). The highest level is the target level, several intermediate levels are the criterion level, and the bottom level is the various options selected for solving the problem, which is called the plan level [24,25]. The weights of indexes are determined by AHP as follows:…”

In the context of current energy shortage and environmental degradation, the penetration rate of demand-side energy resources (DSER) in the power grid is constantly increasing. To alleviate the problems concerning the energy and environment, it is of tremendous urgency to develop and make effective use of them. Therefore, this paper proposes the evaluation model of DSER in urban power grid based on geographic information, and a variety of demand-side energy resources in a region is evaluated. Firstly, as for five kinds of DSER, revolving wind power generation (WG), photovoltaic power generation (PV), electric vehicle (EV), energy storage (ES), and flexible load, the commonality indexes and individuality indexes of all kinds of resources are selected based on geographic information. The commonality indexes are common indexes of all DSER, and the individuality indexes are unique indexes of all DSER. Then the weight of each subindex under the commonality and individuality indexes are determined by analytic hierarchy process (AHP) and entropy weight method, respectively. Finally, weighted overlay are made according to the weights and quantized values of each index, and a comprehensive score is obtained from the commonality indexes and individuality indexes upon various demand-side energy resources in the region. The result depicts that the proposed evaluation model of demand-side energy resources is of well practicability and effectiveness, which is beneficial to the planning of the city and the power grid. Most of all, such model provides a strong support for the long-term optimization planning and the medium-term optimization aggregation of DSER.
