This article presents the state of the art of Lean principles applied in Emergency Departments through a systematic literature review. Our article extends previous work found in the literature to respond to the following questions: (i) What research problems in emergency departments can Lean principles help overcome? (ii) What Lean approaches and tools are used most often in this environment? (iii) What are the results and benefits obtained by these practices? and (iv) What research opportunities appear as gaps in the current state of the art on the subject? A six-step systematic review was performed following the guidance of the PRISMA method. The review analysis identified six main research problems where Lean was applied in Emergency Departments: (i) High Waiting Time and High Length of Hospital Stay; (ii) Health Safety; (iii) Process redesign; (iv) Management and Lessons Learned; (v) High Patient Flow; (vi) Cost Analysis. The six research problems’ main approaches identified were Lean Thinking, Multidisciplinary, Statistics, and Six Sigma. The leading Lean tools and methodologies were VSM, Teamwork, DMAIC, and Kaizen. The main benefits of applying Lean Principles were (a) reductions in waiting time, costs, length of hospital stay, patient flow, and procedure times; and (b) improvements in patient satisfaction, efficiency, productivity, standardization, relationships, safety, quality, and cost savings. Multidisciplinary integration of managers and work teams often yields good results. Finally, this study identifies knowledge gaps and new opportunities to study Lean best practices in healthcare organizations.
Resumo: É importante a adoção de meios que facilitem aos alunos construírem seu conhecimento teórico e prático em assuntos relacionados a operações de manufatura. Nesse sentido, o objetivo deste artigo é apresentar o uso da metodologia ativa de ensino-aprendizagem na compreensão das abordagens da Teoria das Restrições (TOC) em operações de manufatura. Por meio de simulação com o uso do OPT Game, são apresentadas conexões entre o processo da TOC com os indicadores globais e operacionais, as regras do OPT, a sincronização da produção e o tambor-pulmão-corda. Caracteriza-se uma pesquisa aplicada, exploratória, descritiva e explicativa, por meio da técnica de simulação. O OPT Game foi aplicado em uma turma de mestrandos. Os resultados demonstraram que os alunos se sentiram motivados com a atividade, auxiliando-os na compreensão entre teoria e prática das abordagens da TOC; do qual foi considerado importante recurso facilitador à aprendizagem.Palavras-chave: Metodologia Ativa de Ensino-Aprendizagem.

Abstract:It is important adoption means that facilitate the students to build their theoretical and practical knowledge in matters related to manufacturing operations. In this sense, the objective of this article is to present the use of the active methodology of teaching-learning in the understanding of the Theories of Constraints (TOC) approaches in manufacturing operations. Through simulation with the use of OPT Game, connections between the TOC process with the global and operational indicators, the OPT rules, the production synchronization and the drum-buffer-rope are presented. It is characterized an applied, exploratory, descriptive and explanatory research, through the simulation technique. The OPT Game was applied to a group of masters degree students. The results showed that the students felt motivated with the activity, helping them to understand the theory and practice of TOC approaches; whose was considered an important resource to facilitate learning.
Purpose The purpose of this paper is to analyze the perception of the cold chicken meat value in its supply chain and how to manage the influence of quality demands in this supply chain. It is based on the views that retails and restaurants have about the main quality aspects required to meet their end customers. Design/methodology/approach This paper surveyed 135 respondents from restaurants, butcheries, supermarkets, and convenience stores located in the Southern Brazilian metropolitan area. Principal component analysis followed by quality function deployment was performed to analyze the data. Findings The principal component analysis results in seven factors: product quality and flexibility of delivery; supply flexibility; responsiveness to market changes and product assortment; measurements of the inventory and competitiveness; product specificity; product availability and specificity cost; and delivery frequency. The comparative study on the steps of the process between restaurants and retailers shows that distribution, cutting and packaging are the key process steps in this chain. Practical implications The results show what process steps must be prioritized to comply with the customers’ quality requirements. Since the most important process steps are different for different customers, companies may elect what steps require more attention to satisfy the most profitable customer types. Originality/value Several studies are found in the literature that present a theoretical discussion on the quality demands of perishable products. The management of factors related to the process steps can help members of the supply chain in their decision-making processes. The contribution of this research is to identify, by an applied study, how the demanded quality aspects should be considered by the poultry industry to satisfy customers in different market segments.
Resumo: O teste a frio (Cold Test) é um processo inovador no Brasil com relação aos testes em motores diesel. Esse processo foi implementado em uma empresa fabricante de motores diesel, com o intuito Abstract:The Cold Test is an innovative process in Brazil regarding the tests in diesel engines. This process was implemented in a diesel engine company with the intention of becoming the main validation test before engines are sent to customers. Based on this hypothesis, the main reason of this investigation is to test whether it is possible to replace the Hot Test with the Cold Test. This was a shocking question, since the Hot Test is a reliable and established process for over 18 years. This research used a case study method. The detailed research has identified several criteria for comparing the two processes, such as: flowcharts, effectiveness, efficiency, complexity, approval levels, on-board worksheets and company FMEA documents. The results showed that the Cold Test process is more advantageous and sustainable, however the two processes are complementary. The study proved that the fully replacement of the Hot Test by the Cold Test is not possible, mainly the Cold Test process fails in detecting leaks.
Money laundering has affected the global economy for many years, and there are several methods of solving it presented in the literature. However, when tackling money laundering and financial fraud together there are few methods for solving them. Thus, this study aims to identify methods for anti‐money laundering (AML) and financial fraud detection (FFD). A systematic literature review was performed for analysis and research of the methods used, utilizing the SCOPUS and Web of Science databases. Of the 48 articles that aligned with the research theme, 20 used quantitative methods for AML and FFD solution, 13 were literature reviews, 7 used qualitative methods, and 8 used mixed methods. This study contributes by presenting a systematic literature review that fills two research gaps: lack of studies on AML and FFD, and the methods used to solve them. This will assist researchers in identifying gaps and related research.
