Abstract Paper aims This paper analyzes the work quality and productivity of during the COVID-19 pandemic from five Brazilian regions with three work models: face-to-face, virtual and workshiting. Originality Despite the number of studies on COVID-19 since the pandemic’s beginning, the literature lacks research that demonstrates relationships between productivity and the emergence of problems, illnesses, and adverse situations that compromise worker performance in the routines of these three work models. Research method The study used an experimental, descriptive, and transversal research design, without identification data Southeast of the participant, as anonymous and exclusive research, with 801 participants from different regions of Brazil (North, Northeast, Midwest, Northeast, and South), with different age groups. The work consisted of work issues focusing on the quality of work pandemic, for issues of analysis of time and productivity problems. The questions were about health issues in 6 parts of the study: mental demographics and increased sleep quality, fear of SARS-CoV-2, exercise, stress, and productivity. Main findings There was a strong significant relationship between the three work models and five variables: area of activity, work equipment used during quarantine, diseases found during the pandemic, problems reported during quarantine pandemic like sleep, stress, workload performed, and future expectations regarding the work performed and the pandemic. Significant relationships were also found with diseases before the pandemic, those perceived and reported during the pandemic period studied, and the sleep profile before and during. The statistical significance relationship was also strong between the areas of work audience and new diseases during the pandemic. Implications for theory and practice The research practically validates several other theoretical studies, with guidelines for the scientific community on work behavior for the three work models. The results, together with the relationships found by the statistical analysis of the p-value of the variables, help the public and private authorities to understand and rethink preventive measures in the emergence of new diseases and the optimization of work operations without compromising their quality and productivity.

Resumo: Os sistemas de medição de desempenho (SMD) vêm sendo muito estudado ao longo dos anos, porém este é ainda um tema muito importante para as empresas e continua sendo objeto de estudo, pois tais sistemas auxiliam na tomada de decisão, permitem o acompanhamento e controle de indicadores e contribuem para a realização da estratégia de negócios e de operações. Os estudos atuais acerca dos SMD, em sua maioria, versam sobre seus conceitos e definições, modelos, frameworks, recomendações para projeto e implementação, entre outros. Baseado em um conjunto de usos para um SMD descrito na forma de papéis para serem desempenhados, este artigo tem como objetivo principal discutir as inter-relações entre os papéis de um sistema de medição de desempenho, agrupando-os para então indicar recomendações para o seu uso. Para tanto, um survey foi aplicado à representantes de empresas, os quais puderam expressar seus níveis de concordância para os papéis de um SMD. Os dados foram analisados por meio da técnica de análise de cluster, onde os papéis foram agrupados em quatro grupos e comparados com a literatura existente. Dos agrupamentos formados foi possível indicar quatro principais recomendações às empresas, as quais justificam a adoção dos SMD para atingir resultados desejados.

Abstract: The performance measurement systems (PMS) have been studied over the last ten years, but this is still a very important research topic for companies and it keep being studied nowadays, because such systems help in decision-making, they allow monitoring and control indicators, and to assist business and operations strategy realization. The recent studies on PMS mostly are on reviewing their concepts and definitions, models, frameworks, design and implementation recommendations, etc. Based on a study oriented to PMS use described by roles to be played, this article aims to discuss the interrelationships between the roles of a performance measurement system, to cluster them and to formulate recommendations for their adoption and proper use. Thus, a survey collected and analyzed the perception of business representatives, who are able to express their agreement levels for PMS roles and use. Data are analyzed by using cluster analysis technique where the roles forms four groups, which can be confronted with the findings of related works from PMS literature. From the groups formed, it is possible to indicate four main domains of recommendations: to assure the alignment between strategic management of operations and its performance, promoting and improving the overall efficiency and effectiveness of the business operations results; to produce positive changes in organizational systems, processes and culture, developing the capacity to manage continuous improvement projects through integrated strategic management systems; to have a customer-oriented design approach; to be orientated and to manage stakeholders’ demands.

Resumen La solidificación del licor es uno de los pasos más importantes para el procesamiento de los cultivares de cacao. Este proceso se caracteriza como un proceso continuo, que puede convertirse en un obstáculo para la aleatorización de los tratamientos. Este artículo tiene como objetivo la optimización de los factores que influyen en el procesamiento de los cultivares de cacao durante la solidificación del licor. Para eso, se propuso un diseño experimental factorial (DOE) de tres niveles (23) con tres repeticiones. Los tratamientos se organizan en bloques aleatorizados en células divididas (split-plot). El experimento demuestra las mejores combinaciones entre los factores de “flujo de la bomba” y “velocidad de lo transportador” para cada tipo de licor de cacao. La aplicación de este tipo de diseño de experimentos en otros casos puede contribuir a la optimización de procesos con tiempos de set up largos, como los existentes en la industria de alimentos.

Abstract The solidification of the cocoa liquor is one of the most important steps for processing cocoa cultivars. This process is typically characterized as a continuous process, which may become a barrier for the randomization of the applied data treatments. This article aims at optimizing the factors that influence the processing of cocoa cultivars during solidification of liquor. Based on this, it was proposed, as a design of experiment (DOE), a three level factorial plan (23) with three repeated measurements. Treatments were organized in random blocks with divided-cells (split-plot). The experiment presents the best combinations between the factors ‘pump flow’ and ‘conveyor speed’ for each kind of cocoa liquor. The application of this kind of design of experiments in other cases may contribute to optimizing processes with long set up times, such as the ones existent in the food processing industry.

A tecnologia de prototipagem de produtos por adição de material (Rapid Prototyping) e por remoção de material (Subtractive Rapid Prototyping) pode variar em: qualidade, tempo e custos, dependendo das características do produto. A escolha da tecnologia muitas vezes está condicionada à decisão empírica do designer/engenheiro ou operador, devido ao tipo de material, dimensão e precisão. Este artigo apresenta um método para tomada de decisão que auxilia a escolha da tecnologia de prototipagem rápida mais adequada na concepção de novos produtos. Foram utilizados os conceitos de DFM (Design for Manufacturing), CAD (Computer Aided Design), RPD (Rapid Product Development) e MAUT (Multiattribute Utility) em dois produtos de diferente estrutura e material (composto leve e simples maciço) para avaliar e validar o método proposto. Os resultados apresentam comparações entre as tecnologias de prototipagem rápida a partir de critérios para tomada de decisão, aperfeiçoando a concepção de protótipos mais eficientes.

The prototyping of products by additive material (Rapid Prototyping) and by subtractive material (Subtractive Rapid Prototyping) technology can vary in: quality, time and costs, depending on the product characteristics. The selection of technology often is conditioned to the designer/engineer or operator empirical decision due to the type of material, size and accuracy. This paper presents a method for decision making to assist the best choice of rapid prototyping technology on new product conception. We used the concepts of design for manufacturing (DFM), rapid product development (RPD) and computer aided design (CAD) for two products of different structure and material (lightweight dual and simple solid) to evaluate and validate the proposed method. The results show comparisons between the rapid prototyping technologies based on decision making, improving the conception of most efficient prototype.
