Lean, Six Sigma and Lean Six Sigma: an analysis based on operations strategy

There is a growing need for operations management models that contribute to the continuous improvement of company processes, among them we highlight lean manufacturing, Six Sigma and, more recently, Lean Six Sigma (LSS). This article aims (1) to identify and analyse the differences and complementarities in the production decision areas for each one of the three models; (2) to identify the competitive priorities that lead to the best performance as a result of policies followed in the decision areas as a result of the adopted model. First, a theoretical conceptual model was developed based on a review of the literature, followed by a exploratory research questions applied to manufacturing companies that use the lean, Six Sigma or LSS manufacturing models in southern Brazil. The main results show that there are differences in the models in relation to the importance of the decision areas and the performance achieved in the competitive priorities. Individually, lean manufacturing, Six Sigma and LSS have varying degrees of importance in the Facilities, Vertical Integration and Production Planning and Control decision areas. The performance dimensions with the best performance are speed, quality, reliability and cost.

Green supply chain management

Purpose – The purpose of this paper is to identify the main motivating factors and difficulties in implementing GSCM; and to describe and explain how GSCM is being adopted in the Brazilian automotive industry. Design/methodology/approach – To meet the proposed objectives three case studies will be carried out in a Brazilian automotive industry, performing a total of 13 interviews, based on a research protocol. As the data collection instrument, a semi-structured interview was used based on a pre-established script, direct observation and documents from the organization researched. For the analysis of the results, the content analysis method was used, applying a triangle analysis to the research data with the patterns presented in the theoretical reference. Findings – The paper orients the companies in the automotive sector to adopt GSCM practices and principally that internal actions of automakers can be transferred throughout the supply chain. Practical implications – Contributes in a more practical so t...

Sustainable operations management: practices and measures in the food industry

The food industry represents an important economic activity, not only because it is related to basic physiological processes required for human survival but also due to the considerable losses from wasted natural resources identified in food production. Thus, this industry generates significant environmental, social and economic impacts, ranking it among the sectors with the highest greenhouse gas emissions on the planet. Accordingly, this article aims to identify sustainable practices and measures that are being adopted by organisations in the food industry. This research followed a theoretical-conceptual method by conducting a bibliographic survey of research on sustainable actions adopted by companies in the food industry. A content analysis was conducted by extracting twenty articles published between 1999 and 2012 to provide information about sustainable actions reported by authors. The results highlight the important practices and measures identified, categorise the prominent studies in this sector ...

The Application of Sustainable Practices and Performance Measures in the Automotive Industry: A Systematic Literature Review

Abstract: This article identifies the main practices and performance measures, and categorize studies of sustainability in the automotive sector. The research method used was a systematic literature review from databases related to sustainability in the automotive industry published in periodicals from 2001 to 2012. The practices and performance measures identified provide an overview of how the automotive industry is doing in the area of sustainability, thus allowing an engineering manager to adopt and review the sustainable actions carried out by companies, and contribute to the formulation of performance measures that meet the dimensions of sustainability according to the categorization process developed in this study.

CONTROLE DE ESTOQUE: A CONTRIBUIÇÃO DA CONTAGEM CÍCLICA DE MATERIAIS EM UM INSTITUTO DE ODONTOLOGIA

A busca por metodos efetivos de controle de estoque que reflitam dados confiaveis para o planejamento e execucao das operacoes passa a ser um requisito para que as organizacoes sobrevivam no mercado. Assim a qualidade das informacoes dos saldos de estoque faz com a eficiencia dos processos aumente. Para isso, e necessario utilizar metodos que auxiliem no controle do estoque, aumentando o percentual de acuracidade de estoque. Nesta linha, o presente trabalho tem por objetivo analisar a contribuicao da contagem ciclica no controle de estoque em um instituto de odontologia. Para alcancar o objetivo proposto foi utilizado o estudo de caso como abordagem metodologica. Com a implantacao da contagem ciclica de materiais conseguiu-se identificar quais fatores estavam impactando nas informacoes dos saldos de estoque, com isso o instituto implantou acoes para eliminar as principais causas das divergencias. Os resultados da implantacao foram significativos, pois o aumento foi de 14,77% na acuracidade de estoque.

UM LEVANTAMENTO DAS CAUSAS E EFEITOS DA FALTA DE ACURACIDADE NOS ESTOQUES: UM ESTUDO EXPLORATÓRIO

O controle efetivo dos estoques e um requisito para o bom andamento dos processos operacionais, para isso, os dados dos saldos dos estoques devem ser confiaveis. Caso contrario podem gerar efeitos indesejaveis nos diversos ambientes organizacionais. Baseado nessa premissa, o presente artigo objetiva identificar, com base na literatura, os principais efeitos e as principais causas da falta de acuracidade de estoque. Para alcancar o objetivo proposto, escolheu-se o estudo exploratorio e foi adotado como procedimento tecnico a pesquisa bibliografica. As conclusoes demonstram o impacto no nivel de servico como principal efeito da falta de acuracidade, ja em relacao as causas, o erro nos registros de materiais destaca-se como o maior nivel de ocorrencia.
