MCDM Method for Managing the Water Resources Based on Possibility Theory under Bipolar Fuzzy Environment
Authors: Totan Garai, George Biswas, Uttaran Santra and Sourav Kumar GiriAvailable online: 17 October 2024More LessBackgroundUncertainty is a common factor in every real-life decision-making problem. Possibility theory is one uncertainty theory in Fuzzy sets (FS). The possibility-based decision-making under a fuzzy environment is a significant multi-criteria decision-making (MCDM) method.
MethodsA bipolar FS is an extension of a fuzzy set. With the bipolarity concept, we can handle both positive and negative thoughts. In this study, we have provided a possibility mean of a bipolar fuzzy number. We have developed a ranking method for bipolar fuzzy numbers using this possibility concept. A novel possibility MCDM method is suggested for solving the water resources management (WRM) in the Nagpur area, Maharashtra State, India.
ResultsThe MCDM technique is an effective tool for solving WRM problems in an area. Many uncertainties and bipolarities occur together in the Nagpur water resources systems WRM technique with fuzzy is one approach that can be used to solve the area's water problem. We have used the proposed MCDM to address the water-related issues of this district. With this proposed MCDM method, numerically, we employed water resource problems under a bipolar fuzzy environment.
ConclusionThe Nagpur area is covered by Basaltic rock and faces water shortage. The district is experiencing severe water shortages. Groundwater, surface water, and rainfall are three water resources considered as alternatives. According to the proposed MCDM technique in Nagpur district, Groundwater is the best water source from three flanks: quality of water, affordability, and availability.

Evaluation of the Critical Success Factors for Household Product Sustainability
Available online: 09 October 2024More LessIntroductionSustainability and sustainable development have received growing attention in both industry and academia due to concerns regarding the rapid decrease in natural resources and increase in carbon emissions.
MethodsIn this study, we focus on the determination, evaluation, and analysis of the critical success factors in product sustainability by specifically focusing on the household goods industry. In the first phase of the study, we determine the critical success factors by referring to the existing literature and opinions of the experts who have experience in the household goods industry. Next, we use a trapezoidal type-2 fuzzy AHP algorithm to rank the determined criteria and discuss the main findings from a practical point of view.
ResultsComputational results bring several important managerial insights. First, we observe that all three aspects of sustainability (economic, environmental, and social) should be considered to ensure product sustainability. Second, the analysis reveals that cost (economic), quality (economic), generated waste and emission during the life cycle (environmental), energy and water consumption during the life cycle (environmental), and occupational health and safety (social) are among the highly ranked criteria.
ConclusionIn order to increase product sustainability, the companies should determine ways to decrease water usage, energy usage, carbon emission, and waste without neglecting the cost and quality of the product and without ignoring occupational health and safety.
