A crescente importância da cadeia de suprimentos tem levado pesquisadores a desenvolverem um volume significativo de trabalhos sobre o tema. Ao mesmo tempo, devido ao seu recente surgimento, esse fenômeno organizacional é complexo e engloba inúmeras variáveis, tornando igualmente complexo o processo de escolha do objeto de pesquisa por pesquisadores e estudantes. Por essa razão, esse artigo tem o objetivo de proporcionar uma análise dos principais tópicos estudados em 173 artigos sobre gestão da cadeia de suprimentos publicados nos principais periódicos acadêmicos internacionais entre 2004 e 2006. Os resultados mostram que os artigos focam, principalmente, a coordenação e a troca de informações entre empresas, a configuração da produção, o design e o desempenho da cadeia de suprimentos. Além disso, também são destacadas as características de alguns dos principais periódicos internacionais. Diversos tópicos, ainda, precisam ser estudados até que a gestão da cadeia de suprimentos se solidifique como disciplina.In recent years, supply chain management has received greater attention, hence leading researchers to develop many papers on this topic. Due to its recent development, this organizational phenomenon is complex and has many variables, making the process of choosing a research topic also complex for researchers and students. Thus, this paper aims to provide an analysis of the major topics studied in over 173 papers published about supply chain management in the most important international production and operation management journals between 2004 and 2006. The results show that the major topics are coordination, information sharing between companies, production decisions, and supply chain design and performance. Many topics should also be the focus of future studies until the supply chain management becomes a discipline.

Este artigo apresenta um sistema para classificar e codificar trabalhos (SCCA - sistema de classificação e codificação de artigos) que relacionam o Controle da Produção (CP) e o Controle da Qualidade (CQ). O sistema de classificação é baseado em três características principais do artigo: a natureza, o foco e os objetivos. O sistema de codificação emprega a idéia básica da tecnologia de grupo (codificação de famílias de peças), utilizando uma estrutura híbrida de três dígitos para codificar as características mencionadas anteriormente. O SCCA foi criado em função da realização de um survey, o qual procurou ser o mais completo possível, contendo 45 trabalhos que relacionam o CP e o CQ. O sistema é validado por sua utilização na classificação e codificação dos trabalhos encontrados no survey. Essa classificação e codificação serve, ao mesmo tempo, como auxílio para estruturar a revisão bibliográfica e para realizar uma análise geral sobre o tema. A partir dessa análise, este artigo consegue proporcionar maior conhecimento e comunicação das pesquisas existentes atualmente que relacionam o CP e o CQ, além de sugerir novas áreas de pesquisa dentro das relações entre CP e CQ. O artigo destaca ainda a importância de estudar a relação entre CP e CQ.This work presents a system for classifying and codifying papers (PCCS - papers classification and codification system) relating Production Control (PC) and Quality Control (QC). The classification system is based on three main characteristics. These characteristics are: the nature, the focus and the goals of the article. The codification system uses the basic idea of the Group Technology (codification of the families of parts). An hybrid structure with three digits is used to codify the characteristics aforementioned. A survey, compounded by 45 papers (we tried to perform a survey the most complete as possible) was accomplished and used to create the PCCS. The system is validated through its use on the classification and codification of the papers found on survey. The classification and codification is useful to structure the literature about PC and QC and to perform a general analysis about the theme. From the analysis of these papers, using our system, a mental clarification and communication of the researches relating PC and QC is obtained. After such analysis, new research areas within the relations between PC and QC can be suggested. The paper also highlights the importance in studying the relationship between PC and QC.

Abstract This paper aims to discuss how Knowledge Management (KM) can support the Industry 4.0 (I4.0) implementation. The paper analyzes the relevant literature and explores related research opportunities, which can provide insights and assist researchers in future studies. I4.0 technologies can influence work flexibility, autonomy, job performance and innovation, but the acquisition and dissemination of knowledge, especially on the shop floor, remain dependent on employees, indicating human concerns which can be supported by KM. We conducted a literature review on KM and I4.0 on 41 papers selected from the Clarivate Web of Science Core Collection, published between 2010 and 2021. Structured summaries were developed, that lead to broad themes. Findings indicate three themes relating KM and I4.0: Technology, which explores infrastructure demands for implementation and its influence on the knowledge creation process; KM and learning, which reinforces the importance of both hard and soft skills, and indicates the need to investigate enablers factors for knowledge creation and sharing; and Worker engagement, which consider communicational, cultural and trust-related aspects for worker's development. This paper explores the I4.0 implementation and indicate concerns involving workers and the technologies adoption, which can provide insights and assist researchers in future Operations Management practices and related researches.

Abstract The offer of business process modeling methodologies is quite extensive, making it difficult for scholars in the BPM area to choose properly. In this context, this paper has the objective to present the main modeling methodologies, with applications, examples and comparisons. A systematic bibliographic survey and the comparative analysis of these notations used in the implementation of BPM projects have been carried out. According to the bibliometric analysis, the modeling notations of the business process most portrayed in the works surveyed are: BPMN, UML, EPC and IDEF. From the construction of a consistent overview that allows the comparative analysis of the methodologies, in order to select the one that suits better its specificities it can be verified that, although they share the same objective, each notation has its specific characteristics. This study has the main purpose of providing a basis for the adequate indication of the application of studies in the field, especially those destined for papers, dissertations and theses.

Abstract: This paper aims at presenting a structure of implementation of the Workload Control (WLC) approach on a commercial discrete event simulation software by comprehensively demonstrating how to construct and simulate this approach. This research was developed considering the lack of studies fully describing this implementation on this kind of software, which hinders the dissemination and use of the WLC approach by managers. Initially, the logic was developed on a dedicated and structured language and then converted to the simulation software. A detailed description of the WLC implementation contributes to the business domain by facilitating its replication and application in other manufacturing environments, reducing the project time needed to develop the base model and allowing managers and/or researchers to focus directly on the adjustments of the model to the environment being modeled. In the academic domain, this paper addresses a gap in the WLC literature concerning the lack of tutorials for simulation and the lack of information, in the existing papers, regarding the development of the computational model.

Abstract: This paper aims to understand how the interconnection between the tacit and explicit dimensions of knowledge impacts knowledge management and its degree of maturity. Knowledge management maturity is understood as the ability firms are expected to have in order to exercise (to some degree) the skills required to manage knowledge internally. Nonaka and Takeuchi (N&T) model of organizational knowledge management was applied to a sample of companies (segmented by size) from the states of São Paulo, Minas Gerais, and Rio de Janeiro, by using the logic of fuzzy sets. The results have shown that small and medium companies have lower levels of knowledge management maturity when compared to large companies. However, in large companies, knowledge management is at medium levels. In this context, this paper suggests, as management guidelines, that companies measure their professionals' perception regarding the company level of knowledge management, pursuing to identify which of their components should be developed.

Abstract This paper analyzes how design diffusion is changing the organizational logics of established companies. If previously design activities had as its main objective packaging new technologies to create differentials for products and services and to reduce production costs, with the diffusion of digital services currently design activities expand its scope and identify functional and emotional needs from users that are relevant for creating differentiated experiences, that in turn will result in new products and services that incorporate existing and emerging technologies of the firm. This transformation reveals a new organizational strategy, in which design assumes a more relevant position for the creation of innovative business models. However, a point not yet considered in the literature is how companies are restructuring their operations in order to benefit from this transition. This paper analyzes how Brazilian organizations of different sizes and sectors have redefined their management models in order to incorporate design as a catalyst of change. The obtained framework consolidates the main propositions of design while directing of the changes in the organizations in the operational, tactical and strategic levels.
