Lean Six sigma aplicado a uma empresa do setor de embalagens

With the advent of a global economy, Lean Six Sigma meets the demand of new production process that creates products within the customer’s specification without any wastage. The objectives of this work is to use the concepts Lean Manufacturing and Six Sigma parallel to minimize costs, increase the customer base, reduce the delivery time which implies an increase in the turnover of products on the shelves in a packaging company. We used the DMAIC method to continue working. The method DMAIC indicated the main failure modes that were fixed in the step improve. At this stage the tools of Lean Manufacturing gain tremendous value by optimizing processes with defects. The conclusion involves an increase in monthly billing, a corporate restructuring and, finally, a renewal in how to conduct the work of management

Aplicação do lean six sigma na linha de produção de turbinas industriais a vapor

This work evaluates the implementation of Lean Six Sigma into the Steam Turbine’s Blades Manufacturing Process, aiming to improve productivity, quality and operational efficiency. Therefore, several tools have been applied, such as VSM, Spaghetti Diagram, Ishikawa, Pareto, DMAIC, Benchmarking and Control Charts, seeking to propose process improvements, as well as Quality Indicators creation. It was obtained a significant waste reduction throughout the process, achieving a lead time reduction of 42% and 83,41% in transport. Also, were introduced the Lean Thinking concepts, such as pull production and Continuous material flow. At the same time, it was possible to calculate the process capability and the sigma level, evaluating and proposing some improvements

Verificação da eficiência da metodologia Seis Sigma na redução da divergência de estoque em uma indústria de condutores de fluídos

This work was developed in order to reduce the discrepancy found between the stock data of an item in the system and the amount found physically in stock in the company presented on this study case. Therefore, this paper makes a study on system of information that can assist in the collection, control and manipulation of data regarding the company's stock. It is very important to do the inventory management, so we can control the level of this sub-product to meet sales orders and production. In the study discussed below, we used the Six Sigma methodology to identify points that had flaws in the process and thus improve their work where the results show grater process control and provide a reliable database to the point where no further problems of lack of components in stock

A aplicação da teoria do lean seis sigma na prestação de serviços no setor agrícola

This thesis aims to analyze the applicability of Lean Six Sigma and DMAIC to improve processes focused on agriculture. We discuss the origins of each system separately, Lean Manufacturing, the Toyota plants in Japan, and Six Sigma, by Motorola in the U.S., and then appears to merge them and can meet their complementarities and synergy between their tools. Finally, we describe a case study focused on the harvesting department, applicable to all types of manuals crops, covering the production of fruits, vegetables and greens. This study shows the ability to reduce costs, increase productivity and elimination of defects that the methodology developed with the fusion of Lean Manufacturing with Six Sigma allows

Projeto DMAIC com ferramentas six sigma para redução de custos logísticos de uma multinacional

This work has a focus on project execution DMAIC ( Define Measure Analyze Implement Control) , using the statistical and quality tools to identify , analyze and implement improvements in a given process in order to reduce costs telephony transport of a multinational consumer goods . The multinational consumer goods to be studied has outsourced carriers who perform the distribution of its products , which may lead them straight to their factories or one of its distribution centers to the points of sale ( supermarkets , bakeries , gas stations , convenience cafeterias , among others ) . Whenever there is an unexpected situation or some problem at the time of delivery of the goods to the customer opens an occurrence , ie , the carrier responsible for contacts ( 0800 ) with the contact center company of consumer goods which in turn registers the occurrence, analyzes and sends a response action to the carrier . This work will study the problem with a high number of connections to handle occurrence , through analysis and data collection , identify improvement opportunities, implement them and monitor the results to ensure that the gain and loss reduction are sustainable

Projeto DMAIC com ferramentas Seis Sigma para redução de sucata em uma multinacional do ramo de acessórios automobilísticos

In this era of globalization, with fierce competition in the labor market, using the reduction cost strategy and resources optimization, has become a competitive advantage. In this graduation study, it will be exposed in form of case study the DMAIC project (Define Measure Analyze Improve Control) execution, using of Six Sigma's tools, statistical and quality knowledge, with intent of analyze, improve and control the processes of a selected problem, always demonstrating good practice of methodologies. In an auto parts multinational branch, It was identified a high scrap rate in one of his production lines. This work will study this problem to improve their processes and ensure that these improvements are perpetual. As a result, reached the stipulated goals, increasing Corporation's Intellectual, thereby providing a competitive advantage

A new limit of the AdS(5) x S-5 sigma model

Using the pure spinor formalism, a quantizable sigma model has been constructed for the superstring in an AdS(5) X S-5 background with manifest PSU(2,2 vertical bar 4) invariance. The PSU(2,2 vertical bar 4) metric g(AB) has both vector components gab and spinor components g, 3, and in the limit where the spinor components g, 3 are taken to infinity, the AdS5 X S5 sigma model reduces to the worldsheet action in a flat background. In this paper, we instead consider the limit where the vector components g(ab) are taken to infinity. In this limit, the AdS5 X S5 sigma model simplifies to a topological A-model constructed from fermionic N=2 superfields whose bosonic components transform like twistor variables. Just as d=3 Chern-Simons theory can be described by the open string sector of a topological A-model, the open string sector of this topological A-model describes d=4 N=4 super-Yang-Mills. These results might be useful for constructing a worldsheet proof of the Maldacena conjecture analogous to the Gopakumar-Vafa-Ooguri worldsheet proof of Chern-Simons/conifold duality.

In vitro production of bovine embryos using Sigma antioxidant supplement®, α-tocopherol and L-ascorbic acid

This study tested the effect of Sigma antioxidant supplement®, α-tocopherol (vitamin E) and L-ascorbic acid (vitamin C) in the culture medium of bovine embryos. In experiment 1, in vitro produced bovine zygotes were cultured in Human Tubal Fluid (HTF): Eagle’s Basic Medium (BME) with: Group 1 – 50 µm vitamin C; Group 2 – 200 µm vitamin E; Group 3 – 25 µm vitamin C and 100 µm vitamin E; Group 4 – 1 µl/ml Sigma antioxidant supplement®; and the Control group – HTF:BME only. In experiment 2, embryos were cultured in high or low oxygen tension with HTF:BME + Sigma antioxidant supplement® or in HTF:BME alone (Control). The data were analyzed using ANOVA followed by Tukey’s test. The results of experiment 1 showed a negative effect (P < 0.05) of vitamin E on blastocyst production in Group 2 (19.7 ± 0.1%). This effect was reduced in Group 3 by the addition of vitamin C (26.1 ± 0.2%). The use of vitamin C alone (34.9 ± 0.3%) or the Sigma antioxidant supplement® (33.3 ± 0.7%) did not increase (P > 0.05) the number of blastocysts produced compared with the control group (30.1 ± 0.5%). During experiment 2, there was no effect (P > 0.05) from the culture medium or the O2 concentrations used, indicating that the reduction of the O2 concentration did not improve blastocyst production.
