Integração de métodos multicritério na busca da sustentabilidade agrícola para a produção de tomates no município de São José de Ubá-RJ.

Este estudo discute alternativas para os sistemas produtivos da terra no plantio de tomates em São José de Ubá-RJ e as relações de trabalho passíveis de serem colocadas em pratica de forma a promover uma agricultura sustentavel na região, priorizando os aspectos economicos, ambientais e culturais do problema. A introdução da questão cultural aumenta a complexidade da questão, sendo necessário o uso de uma metodologia capaz de lidar com toda a subjetividade envolvida nesse processo de tomada de decisão. O estudo visa contribuir para a conquista de um processo sustentavel na região, estabelecendo um processo de tomada de decisão pautado nas opinioes do agricultor, respeitando principalmente as questões culturais do problema. As características do ambiente de tomada de decisão indicaram o uso de uma combinação de métodos de apoio a decisão multicritério - MACBETH e VIP Analysis - para a seleção da melhor alternativa capaz de possibilitar o alcance dos objetivos propostos

The rank reversal problem in multi-criteria decision making : a literature review

Despite the importance of multicriteria decision-making (MCDM) techniques for constructing effective decision models, there are many criticisms due to the occurrence of a problem called rank reversal. Nevertheless, there is a lack of a systematic literature review on this important subject which involves different methods. This study reviews the pertinent literature on rank reversal, based on 130 related articles published from 1980 to 2015 in international journals, which were gathered and analyzed according to the following perspectives: multicriteria technique, year and journal in which the papers were published, co-authorship network, rank reversal types, and research goal. Thus our survey provides recommendations for future research, besides useful information and knowledge regarding rank reversal in the MCDM field

An integrated multicriteria decision-making approach to reale state evaluation: case of the todim method

Evaluation of real estate properties is an important factor in any economy. The appraisal process is rather subjective, based on the appraiser's experience and intuition. Attempts are being made to help appraisers produce more stable and reliable results. In the paper the authors present an integrated approach to the problem based on the multicriteria decision making framework. The process is carried out through three phases using the multicriteria method TODIM. An "adjusted value" iterative procedure for market value estimation is proposed. The final property price ensures that the overall quality of the alternative obtained through the TODIM method is not farther from the comparable properties on the market than the stated threshold. The process is illustrated through an application in the city of Volta Redonda (Brazil). The results are compared with the "proportional approach". The "adjusted value" approach showed significant improvement compared to the "proportional" adjustment of market value

Measuring the performance of factoring and financial leasing firms under balanced scorecard perspective using pythagorean fuzzy sets

International Conference on Intelligent and Fuzzy Systems, INFUS 2019 -- 23 July 2019 through 25 July 2019 -- -- 228529The Balanced Scorecard introduces solutions to the problems that arise from the failures encountered in strategic management, and the inadequacy of traditional performance management systems that lag behind in the information age, especially, with respect to today’s intensely competitive environment to which enterprises are increasingly exposed. In this study, the performance of 7 factoring and financial leasing firms listed at the Istanbul Stock Exchange (BIST) were evaluated using the Balanced Scorecard approach under 4 main criteria. Pythagorean fuzzy sets are considered as a better way to represent expert-judgments under inconsistent and indeterminate environment. After that, the TODIM methodology, which analyzes decision makers’ psychological behaviors under risk, was used to rank the firms. While the economic loyalty sub-criterion was found as the most important one, learning and growth came out as the least important one after applying interval-valued Pythagorean fuzzy AHP. Finally, factoring and financial leasing firms were ranked according to decision makers under the balanced scorecard performance criteria and followed by a sensitivity analysi

ANP applied to the evaluation of performance indicators of reverse logistics in footwear industry

The reverse logistics (RL) seeks to facilitate the return of consumer goods, or its constituent materials, in the production cycle. The main motivators of RL are economic factors, customer service, legal, corporate citizenship and corporate image. The evaluation of RL practices involves therefore multiple interrelated aspects: environmental legislation, technology, costs, external relations etc. This article aims to present an assessment of the priorities of the indicators of reverse logistics in a small footwear industry in the Brazilian State of Ceara. The model of RL evaluation applies the Analytic Network Process, because it allows assessing dependency relationships or existing influence.
