Multi-criteria food waste treatment method selection using single-valued neutrosophic-CRITIC-MULTIMOORA framework
TL;DR: A novel integrated framework by combining criteria interaction through inter-criteria correlation (CRITIC) and multi-objective optimization based on ratio analysis with the full multiplicative form (MULTIMOORA) methods with single-valued neutrosophic sets (SVNSs) for assessing the multi-Criteria food waste treatment methods selection is offered.
Abstract: Proper management and treatment of food waste have become a key concern due to its significant environmental, social, and economic ramifications. The selection of the most appropriate food waste treatment method among a set of alternative methods can be regarded as a multi-criteria decision-making problem because of the association of numerous qualitative and quantitative attributes. In this paper, we offer a novel integrated framework by combining criteria interaction through inter-criteria correlation (CRITIC) and multi-objective optimization based on ratio analysis with the full multiplicative form (MULTIMOORA) methods with single-valued neutrosophic sets (SVNSs) for assessing the multi-criteria food waste treatment methods selection. In this methodology, the CRITIC technique is applied for computing the attribute weights, and the MULTIMOORA model is employed for estimating the ranking of the options within SVNSs context. To examine the introduced methodology’s efficiency and achievability, a case study of food waste treatment method (FWTM) assessment is discussed in the SVNSs setting. Further, comparative study and sensitivity investigation are offered to certify the presented framework for prioritizing FWTMs. The final results indicate that the proposed approach achieves better solutions than the extant models.

TL;DR: In this article, a reference point theory is used for multi-objective optimization by ratio analysis (MOORA), which takes care of different objectives with the objectives keeping their own units.
Abstract: Multi-Objective Optimization takes care of different objectives with the objectives keeping their own units. The internal mechanical solution of a Ratio System, producing dimensionless numbers, is preferred. The ratio system creates the opportunity to use a second approach: a Reference Point Theory, which uses the ratios of the ratio system. This overall theory is called MOORA (Multi-Objective Optimization by Ratio Analysis). The results are still more convincing if a Full Multiplicative Form is added forming MULTIMOORA. The control by three different approaches forms a guaranty for a solution being as non-subjective as possible. MULTIMOORA, tested after robustness, showed positive results.

01 Nov 2017TL;DR: The proposed new theoretical composite model for selection of elements, materials and other aspects of sustainability can be practically applied in creating the decision support system for the selection of single-family house elements and materials.
Abstract: This article aims to create a theoretical evaluation model based on decision support methods for the residential house construction materials and elements selection. The research and analyses of most of the scientists are invoked on individual elements and materials of the building, which have an impact on different aspects of sustainability. Meanwhile, the integrated model covering all the key elements and materials of the single-family residential house has not been implemented. Thus, the problem of development of the general composite model of the element and material selection of single-family buildings is acute in many countries around the world. Our study assessed the specific technical parameters related to building materials: cost, thermal bridging, and load-bearing capacity, the outer material selection according to localisation, environmental performance, durability, weight. SWARA (Step-wise Weight Assessment Ratio Analysis) approach is applied to decision making to calculate the relative importance of the criteria. A single-valued neutrosophic set governs the proposed new extension of MULTIMOORA (Multiobjective Optimisation by Ratio Analysis Plus Full Multiplicative Form) method and allows to deal explicitly with the indeterminacy of the initial information. Our proposed new theoretical composite model for selection of elements, materials and other aspects of sustainability can be practically applied in creating the decision support system for the selection of single-family house elements and materials.

TL;DR: Zhang et al. as discussed by the authors provided a practical model for site selection decision of photovoltaic hydrogen production project (PVHPP) based on multi-criteria decision-making (MCDM), and take Zhangjiakou City, Hebei Province as an example for analysis.
Abstract: Hydrogen production by photovoltaic power generation can not only effectively alleviate the problem of high cost of electrolysis water by making full use of light resources, but also is an efficient, clean and carbon-reducing way to produce hydrogen. The purpose of this paper is to provide a practical model for site selection decision of photovoltaic hydrogen production project (PVHPP) based on multi-criteria decision-making (MCDM) method, and take Zhangjiakou City, Hebei Province as an example for analysis. Firstly, a set of evaluation criteria system including natural factors, economic factors, technical factors, social factors and environmental factors is constructed. Secondly, probabilistic hesitation fuzzy linguistic term set (PHFLTS) and trapezoidal interval type-2 fuzzy set (TIT2FS) are combined to describe the information of qualitative criteria. Then, the subjective and objective weights are calculated by using best-worst method (BWM) and criteria importance through intercriteria correlation (CRITIC), and the comprehensive weights are obtained by using the idea of game theory. The multi-attribute boundary approximation regional comparison (MABAC) method is then used to sort the alternative plant sites. The ranking results show that A2 (Chongli District) performs the best, and A1 (Qiaodong District) is the second best. Finally, taking Zhangjiakou as an example, sensitivity analysis and comparative analysis are carried out to verify the validity and reliability of the model.

TL;DR: In this article , the authors present a framework for integrating LCA-MCDM approaches, relevant sustainability criteria and related standards were used to present a set of recommendations for performing an integrated LCA and MCDM study that ensure scientifically robust, meaningful and reliable decisions.
Abstract: Decisions on waste management systems are subjected to multiple sustainability criteria, including environmental, social, and economic criteria. Decision makers therefore can benefit from systematic approaches to evaluate different waste management options considering multiple sustainability criteria. This study reviews multi criteria decision making (MCDM) and life cycle assessment (LCA) approaches that assess the sustainability of waste management systems. We present a framework for integrating LCA-MCDM approaches. First, we identified the most used MCDM methods for waste management systems published in the literature and highlight the technical and sustainability criteria used in the literature. Then, key issues in LCA studies of waste management systems were reviewed and discussed. The review results indicated that there are only a limited number of studies that integrated LCA and MCDM to assess the sustainability of waste management systems. Furthermore, more than half of the studies that did use the integrated approach failed to consider all three pillars of sustainability. There is also a lack of detailed information on the life cycle inventory used for the LCA part which reduces the reproducibility and clarity of the studies. In addition, the normalization and weighting methods to convert environmental impact categories for each scenario into single scores were often neither clearly explained nor justified. Also, the detailed information about experts involved in the decision-making process as well as the procedure of acquiring their opinions were not fully presented. Finally, the LCA and MCDM approaches, relevant sustainability criteria and related standards were used to present a set of recommendations for performing an integrated LCA-MCDM study that ensure scientifically robust, meaningful and reliable decisions.

TL;DR: In this paper , a comprehensive framework is proposed in which decision experts (DEs) are capable to assess linguistic values to give their decisions and contribute in the decision-making needs to rank the SEE aspects that affect the sustainable perspective of LCTSs.
Abstract: In this paper, globally existing low-carbon tourism strategies (LCTSs) are recognized and then ranked over fourteen different indicators relevant to SEE analysis (social (S), economic (E), and environmental (E) aspects) of sustainability. A comprehensive framework is proposed in which decision experts (DEs) are capable to assess linguistic values to give their decisions and contribute in the decision-making needs to rank the SEE aspects that affect the sustainable perspective of LCTSs. This paper therefore proposes an integrated decision-making framework considering the various conflicting indicators and SEE aspects of sustainability. In addition, treating of uncertainty and inconsistency for data, we consider a neutrosophic setting with the use of single-valued neutrosophic numbers (SVNNs). First, the MEREC (Method based on the removal effects of criteria) weighting procedure is applied to recognize the relative significance of the SEE aspects and their indicators. Second, the generalized Dombi operators are proposed and their elegant properties are discussed to obtain aggregated information of SVNNs. Third, MULTIMOORA method is used to prioritize alternatives. A case study considering six LCTSs is taken to approve the practicality of the introduced methodology, and comparison discussion is made to illustrate the benefits of the developed methodology. Sensitivity investigation is done to evidence the rationality and permanence of the proposed methodology with variations in indicators’ weights. The outcomes of the study offer valuable facts for low-carbon tourism experts and the outcomes of the case study specify that the LCTS-I is the optimum sustainable LCTSs with overall assessment degree of 0.208 after that LCTS-II with utility degree of 0.172.

TL;DR: This work defines the settheoretic operators on an instance of neutrosophic set, and provides various properties of SVNS, which are connected to the operations and relations over SVNS.
Abstract: Neutrosophic set is a part of neutrosophy which studies the origin, nature, and scope of neutralities, as well as their interactions with different ideational spectra. Neutrosophic set is a powerful general formal framework that has been recently proposed. However, neutrosophic set needs to be specified from a technical point of view. To this effect, we define the settheoretic operators on an instance of neutrosophic set, we call it single valued neutrosophic set (SVNS). We provide various properties of SVNS, which are connected to the operations and relations over SVNS.

TL;DR: A method for the determination of objective weights which is based on the quantification of two fundamental notions of MCDM: the contrast intensity and the conflicting character of the evaluation criteria is proposed.
Abstract: The association of weights in multiple criteria problems is a critical stage of the whole decision making process. In some decision situations the extraction of subjective preferences is either difficult or undesirable. This paper proposes a method for the determination of objective weights which is based on the quantification of two fundamental notions of MCDM: the contrast intensity and the conflicting character of the evaluation criteria. The latter notion is of great importance in interfirm comparisons because the financial indices used are often highly correlated. The method developed is applied to a sample of industrial firms. The results are compared to those obtained by other sets of objective weights and show this method ensures a better compromise of the criteria examined.

TL;DR: In this paper, the authors reviewed the characteristics of food waste, the principles of anaerobic digestion, the process parameters, and two approaches (pretreatment and co-digestion) for enhancing AD in food waste.
Abstract: The uncontrolled discharge of large amounts of food waste (FW) causes severe environmental pollution in many countries. Within different possible treatment routes, anaerobic digestion (AD) of FW into biogas, is a proven and effective solution for FW treatment and valorization. The present paper reviews the characteristics of FW, the principles of AD, the process parameters, and two approaches (pretreatment and co-digestion) for enhancing AD of food waste. Among the successive digestion reactions, hydrolysis is considered to be the rate-limiting step. To enhance the performance of AD, several physical, thermo-chemical, biological or combined pretreatments are reviewed. Moreover, a promising way for improving the performance of AD is the co-digestion of FW with other organic substrates, as confirmed by numerous studies, where a higher buffer capacity and an optimum nutrient balance enhance the biogas/methane yields of the co-digestion system.

TL;DR: The new step‐wise weight assessment ratio analysis method (SWARA) allows including experts, lawyers or dispute parties opinion about significance ratio of the attributes in the process of rational decision determination.
Abstract: The paper considers major principles of application of the multi‐attribute systems to solve legislative tasks. In order to assess dispute resolution methods from economic, social and other points of view, it is necessary to apply methods for assessing solutions according to multiple attributes. All known multi‐attribute methods cannot value the atribute weights as one weight of attribute is higher or lower significant than the other attribute. The new step‐wise weight assessment ratio analysis method (SWARA) allows including experts, lawyers or dispute parties opinion about significance ratio of the attributes in the process of rational decision determination. SWARA method could be applied in practical implementation of specialised decision support systems and alternative dispute resolution in virtual environment. Starting with principles and established approaches, a problem‐structuring methodology was developed which would condition the problem to allow a more thoughtful application of existing...

TL;DR: In this article, the authors present feasibility and constraints of applying industrial symbiosis in recovering waste from food processing, focusing on recycling (excluding energy recovery) of the solid and liquid waste from the food processing industry.
Abstract: The production of food waste covers all the food life cycle: from agriculture, up to industrial manufacturing and processing, retail and household consumption. In developed countries, 42% of food waste is produced by households, while 39% losses occur in the food manufacturing industry, 14% in food service sector and remaining 5% in retail and distribution. Increasingly, industrial ecology concepts such as cradle to cradle and circular economy are considered leading principle for eco-innovation, aiming at “zero waste economy” in which waste are used as raw material for new products and applications. The large amount of waste produced by the food industry, in addition to being a great loss of valuable materials, also raises serious management problems, both from the economic and environmental point of view. Many of these residues, however, have the potential to be reused into other production systems, trough e.g. biorefineries. The present work focuses on the use of food waste coming from food manufacturing (FWm). Through extensive literature review, the authors present feasibility and constraints of applying industrial symbiosis in recovering waste from food processing, focusing on recycling (excluding energy recovery) of the solid and liquid waste from food processing industry. The main uses of functional ingredients derived from this transformation are presented and discussed, highlighting mainstream sectors of application, e.g. in the nutraceutical and pharmaceutical industry.
