The global electricity grid needs an update due to several factors, such as demand growth, use of renewable energy sources, reduction of environmental impact, and the need of reduction of non-technical losses of electricity. Updating the power grid involves the concept of smart grids, in which there is a bidirectional flow of real-time information on how much energy is produced, consumed, and stored. Smart meters play a fundamental role in the implementation of these smart grids. This article aims to aims to identify some essential issues regarding the residential consumers’ acceptance of smart meters.. In this work, a systematic review of the literature is performed using the PRISMA protocol. The results show that interest in the topic has been increasing in recent years. In addition, applied research is carried out mainly in Europe, North America, and Asia, with some occurrences in Oceania and just one in Africa. None occurrence of applied studies in Brazil and throughout Latin America was found. The need to understand the smart meteracceptance in South America is highlighted, and the results of the present study may be used as a starting point.

As empresas têm utilizado cada vez mais os indicadores de desempenho como meio de monitorar seus resultados. Conhecer o comportamento dos processos é importante para busca dos resultados operacionais almejados. Sendo assim, este trabalho apresenta um estudo sobre o comportamento de três indicadores de desempenho operacionais utilizados em um Centro de Distribuição Direta e sua contribuição para o desempenho operacional. Os indicadores selecionados foram: percentual de vendas efetuadas aos clientes da base, percentual de devolução e percentual de fora de rota. Partindo da hipótese de que esses indicadores refletem o volume de vendas, com o auxilio do software livre GrETL, foi analisado o modelo dos mínimos quadrados, depois realizado o teste de RESET, a análise de correlação e por fim o ajuste utilizando Cochrane- Orcutt. De acordo com os dados analisados aceitou-se a hipótese inicial, revelando que o modelo composto pelas 3 variáveis explica 51% do volume de vendas.

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.La solidificación del licor es uno de los pasos más importantes para el procesamiento de l...

Lean product development (LPD) is an approach that comprises lean principles and management practices that aim to reduce waste and improve operational effectiveness throughout the entire value stream in continuous improvement endless journey. Due to that, the ability to innovate, change and learn continuously is a key element in order to minimize product development problems. Several LPD techniques are presented in the literature as possible enablers for lean implementation. However, little has been known about the impact of these enablers on the problems related to product development processes. Thus, this paper aims to examine the relationship between five LPD practices' constructs and the occurrence frequency of eleven LPD problems' constructs in companies that are implementing lean. Moreover, the identification of relevant relationships between LPD practices' and problems' constructs may contribute to specify the contexts in which problems are expected to occur. ...

Despite the fact that lean production (LP) is widely used by companies from a broad number of countries and sectors, to achieve a mature LP project implementation is still considered hard to accomplish and sustain. The fact that LP is highly context dependent is one of the major difficulties that hinder its implementation. The extant knowledge about LP implementation from emerging markets is still murky and substantially lower than from developed countries This paper emphasizes LP in Brazil, one of the emerging economies where there is relatively little knowledge about how companies are implementing LP. The existing literature of LP in this country is rare and focused mainly on case studies with a few selected companies. For that, a survey with 49 firms of the automotive supply chain of Brazil was carried out and data collected was analyzed by means of multivariate techniques.

Um dos principais pilares da manufatura enxuta (ME) é a capacidade de parar processos sempre que problemas são identificados, corrigi-los antes que afetem a produção; isto é chamado de jidoka. Neste artigo propomos uma pesquisa para avaliar as relações entre os fatores críticos de sucesso (FCS) que promovem a Cadeia de Ajuda (CA). As relações foram determinadas e validadas através de uma pesquisa realizada com 50 empresas brasileiras. Objetivando identificar as relações relevantes entre os indicadores de desempenho dos FCS e poder contribuir em contextos que possam ocorrer problemas. Além disso, o estudo se concentra em duas variáveis conceituais: (i) número de funcionários e (ii) tempo de implementação lean. Nossos resultados evidenciam que o tamanho da empresa e FCS possuem uma relação significativa com a qualidade. Sobretudo, para o OEE, o tempo de implementação enxuta parece ser significativamente importante para prever o desempenho da empresa.

The automobile industry has shown a greater variety of products in an attempt to better meet customer needs. However, not always the greatest product variety is associated with a higher amount of sales, since the production costs tend to increase with higher levels of variety. The objective of this work is to identify the association between the variety of vehicles in the Brazilian market and the sale of vehicles. The sample represents the year 2013 and incorporates 94,35% of volume of sold cars in Brazil, with a total of 118 different models analyzed. The results presented confirm that the variety of cars available in Brazil is significantly associated with the sale of vehicles. Moreover, according to the market segment (entry, compact, sedan, 1

One of the main pillars of Lean Manufacturing (LM) is the capacity to stop processes whenever problems are identified, correcting them before they move downstream; which is called jidoka. Within the concept of jidoka, one of the practices of control and elimination of waste is the help chain (HC). Few evidences have been found in the literature with regards to HC implementation, and the existent ones poorly describe how to operate, systematize and manage the HC in companies undergoing a LM implementation. In this paper we propose an instrument for assessing the relationships between the critical success factors (CSF) that promote HC, providing means to enhance operational efficiency and quality performance in companies undergoing LM implementation. The aforementioned relationships were determined and validated through a survey carried out with 50 Brazilian companies. Identifying relevant relationships between CSF and performance indicators may contribute to specify the context in which problems are expected to occur. Additionally, the study focuses on two contextual variables: (i) size of the company and (ii) time of lean implementation. Our results show that these size of the company and CSF have a significant relationship with quality. However, for efficiency, time of lean implementation seems to be significantly important to predict its performance.

Service modularity has been attracting growing interest in the last decade, especially in how modularity can benefit service research and service providers. The application of modularity concepts in service context has been discussed as a way to achieve benefits such as increased variety, economy of scale, and decreased lead times. Nevertheless, although the literature suggests that service modularity can positively influence service performance, the research on the evaluation of service modularization results is still scarce. The assessment of service modularity results is necessary for the application of modularity concepts in service organizations by demonstrating the potential of modularization in achieving benefits and improvements. Therefore, this work proposes an approach to assess service modularity results based on the performance measures from modularity literature. These modularity performance measures should be selected and prioritized according to service characteristic...

The achievement of a better customer service level drives companies to structure their inventory management. High levels of inventory can cause an increase in operational expenses. However, maintaining reduced inventory levels tend to reduce the customer service level, resulting in losses and damaging the company's image in the business. This work aims at the development and implementation of a proposal to standardize the decision-making regarding the management of finished goods inventory in a small electronics sector company. The main result of this work is presented as the development of the method done from a cause and effect diagram of the company's problems and the nine steps application of the proposed method. Through this inventory management method, it is intended to improve the level of service, reducing the lack of finished goods in order fulfillment.

Socio-technical (ST) theory emphasizes the notion that the design and performance of new systems can be improved, and can only work satisfactorily within an organization, if the social and the technical are brought together and treated as interdependent aspects of a work system. The implementation of Lean Manufacturing (LM) principles and practices has become popular, despite increasing demand on the current and emerging work force to achieve higher levels of quality and flexibility with lower costs. Exploratory studies that investigate how LM practices influence the effect of ST practices on performance are still scarce, and a holistic view of such relationship is needed. In this context, this study aims at verifying the moderating effect of just-in-time (JIT) practices on the relationship between socio-technical practices and the performance of quality and workers’ health. We carried out a survey with 144 different companies from Southern Brazil that are undergoing a lean implemen...

Regardless the kind of organization, a successful lean manufacturing (LM) implementation is highly dependent on its people, both leaders and followers. Hence, the way leaders act and behave influence the attitudes and behaviors of the followers, setting the predominant culture within the organization undergoing a lean implementation. This article aims at identifying the leadership styles and contextual variables that best support companies undergoing a LM implementation. To achieve that we apply a clustering method that combines information gathered from a survey carried out with 68 leaders from different companies with different levels of lean implementation. Our approach identifies leadership styles that may contribute to the level of lean practices adoption considering specific contextual variables of the leadership such as age, experience and size of team. We argue that, viewed as an evolutionary process, there is more than one best way to lead teams that are implementing lean. ...

ABSTRACT The incorporation of tools into New Product Development (NPD) process tends to contribute to the implementation of Mass Customization strategy in companies. Different knowledge areas – such as marketing, design and engineering – offer tools for different stages of product development. The specificity of those tools makes their selection and application to NPD process difficult. This paper aims at carrying out a literature review of applicable tools in respect to the NPD aimed at MC promotion. It also aims at identifying, according to its objective, its localization and application to NPD process. By means of a systematic review, 39 tools for NPD were identified. The results present bibliometrics on the tools, identify four tool clusters according to their contributions to product development, and also identify opportunities for research about the theme.

O aumento da variedade de produto e mencionado como uma alternativa para atender melhor as necessidades especificas dos clientes. Apesar disso, o aumento de opcoes no portfolio de produtos pode resultar em uma reducao do desempenho operacional da empresa. No setor automobilistico, se verifica um crescente numero de opcoes disponibilizados aos clientes, mesmo que estudos recentes indiquem uma baixa associacao entre variedade disponibilizada aos clientes e volume de vendas em alguns mercados. No cenario nacional, os automoveis ainda apresentam uma quantidade restrita de opcoes de customizacao comparado com os niveis disponibilizados nos paises desenvolvidos. Este estudo tem por objetivo comparar a associacao entre variedade disponibilizada nos automoveis brasileiros e americanos com o volume de vendas em cada mercado. Por meio de uma analise de correlacao de Spearman, os resultados indicam que a associacao entre vendas e variedade externa no mercado brasileiro (ρ=0,642) e maior do que...

Programas de implantação de medidores inteligentes nas residências são fundamentais para se atingirem as metas de modernização da rede elétrica e uso racional das fontes de energia. Porém, além da implantação dos aparelhos nas residências é necessária a aceitação dos consumidores, que possuem papel fundamental na redução do uso de energia elétrica. O objetivo deste estudo é investigar na literatura quais fatores influenciam positivamente (benefícios) e negativamente (barreiras) para a aceitação. Para isso, foi realizada uma revisão sistemática da literatura usando o método PRISMA (Preferred Research Items for Systematic Review and Meta-Analyses). Foram analisados 172 artigos, dos quais 42 são estudos aplicados. Os resultados sugerem 26 fatores diferentes que influenciam a aceitação, sendo os benefícios mais importantes “melhor gerenciamento de energia através do feedback”, “eco-preocupação” e “expectativa de ganho financeiro”, já as barreiras mais relevantes são “segurança ameaçada”...

Devido a uma crescente concorrência mundial em relação ao desempenho operacional e lucros empresariais, a Lean Manufacturing (LM) tem sido uma matéria emergente e relevante entre os cursos de pós-graduação em Engenharia de Produção e Gestão de Negócios. Apesar dos avanços no ensino de princípios e técnicas de LM, o caráter prático inerente ao LM mina a aprendizagem e o desenvolvimento dos alunos. Nesse sentido, este estudo visa propor uma metodologia para aprimorar o aprendizado de LM de graduados em Engenharia de Produção de um curso de pós-graduação stricto sensu. A metodologia proposta combina os métodos tradicionais de ensino com a abordagem PBL (abordagem baseada em problemas), baseada em problemas reais de empresas em fase de implementação lean. O método é ilustrado com um exemplo em uma universidade pública brasileira, que foi um dos precursores no ensino de Engenharia de Produção no Brasil em nível de pós-graduação.

PurposeThis study is to propose a procedure to support decisions on which enablers should be employed to minimize the impact of barriers to implementing mass customization strategies in food companies.Design/methodology/approachThrough interpretive structural modeling, the authors analyzed the relationships between barriers. Then, with an approach similar to the quality function deployment technique, commonly used in general product and process development, the authors clarified the relationships between barriers and enablers.FindingsThe results revealed 19 barriers and 17 enablers for implementing food mass customization. The analysis indicates that most of the barriers (16) present strong associations with each other. The barrier “products with non-customizable features” depends on the whole chain of associations and causes a minor impact on the other barriers. In turn, the barrier “ingredient incompatibility” causes impact over the whole chain, and its dependence on other barrier...
