The use of lean tools to improve the performance of an elevators company

This paper presents a project developed in an elevators company, in the framework of a master thesis at University of Minho. The main objective of this work was to analyse the production system of one assembly section of the company and to implement some proposals that would improve its performance. This objective was achieved by applying Lean Production tools and techniques namely, 5S, Visual Management and St...

An industrial application of the SMED methodology and other lean production tools

This paper describes the improvement of the setup process of a mechanical press machine in the metal-mechanic area of an elevators company. The work results from a master thesisc project conducted during a period of five months. The Single-Minute Exchange of Die (SMED) methodology and other Lean Production tools (5S, Visual Management and Standard Work) were applied to reduce the setup times observed at the beg...

Benefits of lean management : results from some industrial cases in Portugal

This paper documents a set of Industrial Lean projects over a decade timespan in the North of Portugal, which were conducted by final year students of the Integrated Master Course on Industrial Management and Engineering (IME) in partnership with the Department of Production and Systems of University of Minho. The study analyses a total of forty one such projects and reveals a clear growth in the number of Lean...

An application of the SMED methodology in an electric power controls company

Lean production is a strategy for high competiveness in manufacturing. The capability for economical manufacture in small batch sizes is an essential requirement for achieving lean production. This facilitates mixed production of several kinds of products to match varying product demand and can have a major impact in reducing inventories. An obvious requirement for this is the high frequency of equipment setups...

Este artigo apresenta alguns resultados de um projecto de implementação da metodologia Quick Changeover (QCO) nas linhas de montagem final de uma empresa de auto-rádios. Esta implementação incluiu a aplicação de Single Minute Exchange Die (SMED) e o desenvolvimento de sistemáticas de trabalho normalizado, tanto numa linha de montagem final como nas áreas adjacentes. Os resultados da implementação do SMED e das ...

Waste identification diagrams

CLME'2011 / IIICEM – 6º Congresso Luso-Moçambicano de Engenharia - 3º Congresso de Engenharia de Moçambique Maputo, 29Ago - 2Set 2011 - Edições INEGI 2011, (ISBN: 978-972-8826-24-6), Ref: CLME’2011_0912A ; The most popular and perhaps the most effective way to represent the material flow in production units is the diagram known as Value Stream Map (VSM). Moreover these maps are also used to help in the identif...

Lean production promotes thinkers, not "androids"

This paper presents the role of the Lean Production paradigm as promoter of the workers’ human potential. In the literature it is possible to find out many authors who have a negative opinion about Lean Production and consider this organizational model as an extension of Taylorist/Fordist model where the worker is seen as a gear in the “big machine”. Based on literature review and on the Toyota Production Syste...

Towards eco-efficient lean production systems

Lean Production has proved itself a worthwhile production strategy in many distinct industries across all regions of the planet by achieving higher levels of production efficiency. Several authors identified that Lean inadvertently has had significant environmental gains. Such achievements are considered of special relevance in a global and highly competitive economy which is progressively both tied-up and driv...

Measurement rounding errors in an assessment model of project led Engineering E...

This paper analyzes the rounding errors that occur in the assessment of an interdisciplinary Project-Led Education (PLE) process implemented in the Integrated Master degree on Industrial Management and Engineering (IME) at University of Minho. PLE is an innovative educational methodology which makes use of active learning, promoting higher levels of motivation and students’ autonomy. The assessment model is bas...
