This paper aims to show how creating a risk plan can be solved with the help of the constructivist multicriteria method. A case study using Multicriteria Decision Aid Constructivist (MCDA-C) was applied, with cybersecurity framework's controls as a reference. The study was conducted in a large Brazilian bank in Brazil. The relevance of this work is the need to show that the application of multicriteria methods can be applied in the context of information security, which recommends the use of such methods to assist in risk analysis. The methodology used in this study was both quantitative and qualitative, obtaining primary data through brainstorming with decision-makers and forms answered by experts. The secondary data were obtained through the Framework for Improving Critical Infrastructure Cybersecurity, created by NIST -the National Institute of Standards and Technology of the United States. The problem was structured according to the constructivist method, and the data collected were processed and calculated. The study concluded that the category of Security Continuous Monitoring controls stood out compared to other categories. It also shows the importance of applying the constructivist method for the management of cyber risks by unravelling a problem and providing a basis for decision making. Our work contributes to a better understanding of risk management, encouraging the adoption of the constructivist method as a form of risk management best practice.
Due to its vast maritime coast, connected to the riverbeds that flow into the sea, Brazil holds favorable conditions for cargo transportation by cabotage—a type of navigation performed between points on the coast or between these and river points. The purpose of this study was to develop and apply a model to evaluate the degree of satisfaction of users of Brazilian cabotage, specifically the containerized cargo segment, with the services offered to them. The assessment model was developed based on the multicriteria decision aid (MCDA) methodology, which was designed under the aegis of the constructivist paradigm and with the collaboration of a team of cabotage specialists. A framework was built for assessment consisting of seven axes: service level, cargo safety, cabotage routes, transportation cost, general aspects of transportation, quality of information provided by EBNs and intermediary agents, and other aspects related to transportation. The global assessment obtained a score of 7.0, on a scale of zero to ten, which is considered good. The study’s contribution to the transportation sector consists of the construction of a multi-criteria assessment model, which can be replicated for other types of transportation with the necessary adjustments.
The purpose of this study was to develop and apply a model to evaluate the operating conditions of cargo transportation by cabotage in Brazil, from the perspective of Brazilian shipping companies operating in this segment. The evaluation model was developed based on the Multicriteria Decision Aid (MCDA) methodology, conceived under the constructivist paradigm and with the participation of a team of experts in cabotage, who built a framework for evaluation of this transportation mode. The global evaluation of the conditions of cargo transportation by cabotage in Brazil, based on this framework, was scored 3.9, - on a scale of zero to ten, - a score considered extremely low for a segment of cargo transportation so important and with such weight to the Brazilian economy. It was concluded that this score reflects the situation of shortage, neglect, and abandonment currently faced by shipping companies that offer cargo transportation services along the Brazilian coast. This work contributes to the construction of a multicriteria evaluation model, which can be replicated for other modes of transportation, with the necessary adjustments.
Grupos musicais independentes são aqueles que atuam de forma autônoma, sem grandes investimentos ou parcerias, e coordenando suas próprias ações. Nesse sentido, os membros desses grupos precisam desenvolver habilidades e praticar funções que vão além do universo musical, para assim manterem um bom desempenho e alcançarem suas metas. O presente estudo teve como objetivo avaliar a gestão colaborativa de grupos musicais independentes. Para tanto, utilizou-se da metodologia Multicritério de Apoio à Decisão (MCDA), realizou-se uma pesquisa de campo, na qual representantes de quarenta e dois grupos musicais de Brasília responderam a um questionário, avaliando a gestão de seus respectivos grupos, de acordo com os critérios estabelecidos no modelo de avaliação. A construção do modelo de avaliação constou de sete etapas: Definição do rótulo do problema, identificação dos atores envolvidos no processo de avaliação, determinação dos elementos de avaliação (critérios), definição dos descritores, construção das funções de valor, determinação das taxas de substituição e construção da árvore de valor. Os dados foram tratados pelo software Hiview3 e analisados com base no modelo de avaliação desenvolvido. As avaliações obtidas na pesquisa foram baixas, indicando a insatisfação dos representantes dos grupos musicais independentes de Brasília com a gestão colaborativa exercida em seus respectivos grupos e demonstrando a necessidade de implementação de melhorias em seus sistemas de gestão e de produção.
