Purpose The purpose of this paper is to identify the relationship between the frequency of publication on food supply chain (FSC) traceability and the occurrence of foodborne diseases outbreaks. Design/methodology/approach A systematic review of the literature was carried out to locate the main articles published in the literature, followed by a content analysis in order to list the main food traceability technologies and their evolutions. Finally, a Spearman’s ρ correlation analysis between the frequency of publications on FSC traceability and the annual occurrence of foodborne outbreaks in the five largest food exporting countries in the world was performed. Findings In these analyses, the tools of radiofrequency, deoxyribonucleic acid, wireless sensor network, hazard analysis and critical control points and Internet of Things are the most researched technologies, and they are relevant in the evolution of traceability in the FSC. With correlation coefficients above 0.700 at 0.01 significance levels, this evolution of food traceability technologies has been one of the factors reducing the number of food outbreaks in the USA and Germany, countries with greater development of the health system and food control. Originality/value This paper provides an evaluation of the food traceability technologies and the effects of their evolutions in the occurrence of food outbreaks. This may help in the proposal of public policies related to food and outbreak control.
The maintenance function is critical to ensuring that products and services meet the needs of diverse stakeholders. Specifically in the industrial sector, the maintenance of physical assets such as machinery, equipment, facilities and systems make an effective contribution to the profitability of the business. The concepts, techniques and methodologies applied to asset maintenance management have evolved since the principles of industrialization, through the consolidation of Total Productive Maintenance-TPM, and currently seeking the application of technologies called industry 4.0. However, the application of concepts, techniques and tools by industries vary according to the degree of maturity of the process management model. Maturity assessment models are applied in various industrial processes, with the purpose of evaluating whether or not organizations have maturity for the implementation of new technologies. Thus, this paper presents an analysis of the methods for evaluating the maturity level of the maintenance-oriented maintenance management system 4.0. The proposed model was built based on the literature review, the analysis of its results and comparison of evaluation models currently applied to industrial maintenance. To build the model, three priority elements were considered: People and their skills, Maintenance processes or routines, and Digitization. Thus, it was observed that the evaluated models meet the priority elements People and Processes, however, they are deficient in relation to emerging technologies of industry 4.0.
Com relação ao tema Big Data, observa-se atualmente uma quantidade significativa e um aumento considerável de publicações relacionadas ao assunto, porém ainda os pesquisadores sentem falta de meios para auxiliar na escolha dos referenciais teóricos. Desta forma, o objetivo deste trabalho é demonstrar um processo utilizado para a seleção das publicações relevantes, as quais são o produto de uma revisão sistemática da literatura e que buscam nortear os pesquisadores, agregando conhecimento para conduzir uma pesquisa sobre os métodos analíticos aplicados em Big Data, em ambientes de Manufaturas Inteligentes e apoiadas por abordagens multivariadas. Para buscar esse objetivo foi desenvolvido um roteiro de pesquisa e uma técnica de classificação das publicações mais relevantes. Como principais resultados deste processo, foi possível identificar 14 publicações aderentes, e que permitiram integrar os conceitos sobre Big Data, Indústria 4.0 e abordagens multivariadas, além de demonstrar a análise preditiva de dados como uma dos modelos mais utilizados na análise de Big Data.
A indústria 4.0 também conhecida como quarta revolução industrial, possui foco na produção inteligente. Neste contexto, a manufatura aditiva é uma importante tecnologia, pois tem revolucionado a maneira de produzir peças. Essa técnica de processo por adição, estabelece sucessivas camadas de material até atingir a forma desejada. Este artigo foi desenvolvido com objetivo de apresentar uma análise sistemática que identificou artigos científicos que destacam a importância da manufatura aditiva na indústria 4.0. A pesquisa demonstra que publicações relacionadas ao tema são recentes, com crescimento de 2017 a 2019, observou-se características como a relação de autores, periódicos e relevância científica das publicações. Para validar a busca de conhecimento na pesquisa, utilizou-se a metodologia ProKnow-C, que proporciona um procedimento estruturado para revisão. O portfólio bibliográfico encontrado, destaca a versatilidade da manufatura aditiva que desempenha um papel fundamental na indústria 4.0, reduzindo tempo, custos e desperdícios, aumentando eficiência e assim permitindo uma prototipagem rápida.
