“…The present methodology of fuzzy VIKOR was compared with fuzzy TOPSIS 34 and fuzzy GRA 35 approach as reported in Table 14. From Table 14, the ranking order for different alternative composite material using proposed (Fuzzy VIKOR) methodology is as A-3 > A-2 > A-4 > A-1 > A-0, while A-3 > A-2 > A-1 > A-4 > A-0 and A-3 > A-4 > A-2 > A-1 > A-0 was the ranking order when solved with fuzzy TOPSIS and Fuzzy GRA methods, respectively.…”

Development and selection of an adequate bearing material with distinct characteristics for wear resistant applications is one of the most crucial tasks. Inappropriate selection of material may cause hindrance and result in failure of components during its functioning. To this end, this research focusses on fabrication of bearing materials reinforced with varying weight percentages of industrial waste, i.e. marble dust, and the physical, mechanical and tribological characteristics were determined. The proportions of marble dust were varied from 0 wt. % to 10 wt. % with a gap of 2.5 wt. % and filled in a silicon-bronze alloy. The physical and mechanical properties were realized by the Archimedean principle, micro-hardness tester and Instron 3369 universal testing machine respectively. The tribological properties such as friction and wear behaviour were determined utilizing pin-on-disk tribometer under different condition at normal room temperature. Due to the conflicting nature of desired properties in a bearing material, the Vise Kriterijumska Optimizacija Kompromisno Resenjemeaning under fuzzy environment was applied to rank and select the optimal composite among available alternatives because it can obtain compromise solution considering overall satisfaction and regret of the selection of the wrong provinces. From the analysis of the results, it was found that silicon-bronze-3 marble dust bearing material containing 7.5 wt. % marble dust achieved the best possible set of the properties for wear resistant applications.

China's renewable energy power has developed rapidly in recent years. Evaluating the external benefits of renewable energy power can provide a reference for the Chinese government to set diverse development goals and to implement differentiated supporting policies for different renewable energy power types, which can promote their sustainable development. In this paper, a hybrid MCDM method was applied to evaluate the external benefits of China's renewable energy power. Firstly, the impacts of renewable energy power accessing the power grid for multiple stakeholders in the electric power system were analyzed. Secondly, the external benefit evaluation index system for renewable energy power was built from the economic, social and environmental factors, based on the concept of sustainability. Then, the basic theory of the hybrid MCDM method employed in this paper was introduced in two parts: the superiority linguistic ratings and entropy weighting method for index weight determination and the fuzzy grey relation analysis for ranking alternatives. Finally, the external benefits of wind power, solar PV power and biomass power were evaluated. Taking a regional electric power system as an example, the results show that PV power has the greatest external benefit, followed by wind power and biomass power. Therefore, more policies supporting PV power should be put in place to promote the harmonious and sustainable development of the whole renewable energy power industry.
