Construction and demolition waste management: Fuzzy Analytic Hierarchy Process approach

Abstract

<jats:p> Construction and Demolition Waste (CDW) has recently received significant attention in the most developing countries, such as Iran. Since CDW generation is unavoidable, so development and implementation of an appropriate CDW management is widely recognized as an essential need. Different alternatives in CDW management have been proposed and implemented currently. In this study, a novel framework was established based on the Fuzzy Analytic Hierarchy Process approach in order to assess different CDW management alternatives in Tehran, Iran. Proposed alternatives (including landfilling, recycling, reusing, and reduction) were investigated with respect to 16 different individual criteria. The criteria were divided into four different groups, namely environmental, social, technical, economic. A database in this study was established through a questionnaire survey. The relative significance of alternatives with respect to each criterion was assessed. The obtained results revealed that reduction has the highest and landfilling has the lowest priorities. Furthermore, it was found that economic criteria have the highest and social criteria have the lowest importance among the studied criteria. Also, the proposed framework can be used as a beneficial tool that will assist decision-makers in determining the most suitable CDW management alternatives in the case of different criteria that are completely/partially in conflict. </jats:p>

A Synthesis of Express Analytic Hierarchy Process (EAHP) and Partial Least Squares-Structural Equations Modeling (PLS-SEM) for Sustainable Construction and Demolition Waste Management Assessment: The Case of Malaysia

“…AHP refers to an structured technique for analysing multi-criteria decision making (MCDM) problems according to a pairwise comparison scale [90], which manages a large number of decision factors and provides a taxonomic process to rank a lot of decision variables [24,91]. AHP has extensively been applied in different areas of construction management such as construction technologies assessment, material assessment, market decision making, contractors' selection, equipment selection, etc.…”

Prioritizing the effective strategies for construction and demolition waste management using fuzzy IDOCRIW and WASPAS methods

“…CDWM is an interesting and emerging field in the construction industry (Khoshand et al , 2020). The negative consequences of poor CDWM can be the most conspicuous feature of this industry, which has become a significant concern (Khoshand et al , 2020; Mahpour, 2018; Khodaverdi et al , 2008). There have been studies in the area of improving CDWM.…”

“…Zhang et al (2020) proposed a heterogeneous group decision-making method for the CDW utilization mode selection problem with interval-valued hesitant fuzzy numbers. Khoshband et al (2020) presented a fuzzy AHP approach to evaluating different CDWM alternatives in Tehran, Iran.…”

“…The lack of a clear political or legal framework can generate a possibility to exploit it in a manner that is not aligned with its original intention. Moreover, the lack of (1) sufficient funds and financial resources, (2) effective strategic plans, (3) skilled personnel in implementing a CDWM plan and (4) limited public participation and so forth are some existing practices that demonstrate the prevention of developing an efficient CDWM (Khoshand et al , 2020; Asgari et al , 2017). Boosting productivity and facilitating the performance of construction projects are other CDWM remarkable ramifications (Khoshand et al , 2020).…”

An Evolutionary Game Theory Study for Construction and Demolition Waste Recycling Considering Green Development Performance under the Chinese Government’s Reward–Penalty Mechanism

“…Therefore, free-riding behavior should be considered in the decision-making process of the closed-loop supply chain. In order to maintain the operation and development of an enterprise, the decision-maker is most concerned about profitability [15]. The social reputation and corporate image gained by production units in the process of participating in the closed-loop supply chain belong to social performance, which can promote the sustainable development of enterprises [16].…”
