Metodologia de implantação da construção enxuta: estudo de caso em construtora de porte médio

In recent years, the Brazilian construction industry has gone by changes like currency stability, increasing competition, shortage of skilled labor and increasing quality importance required by the customer, who made the sector companies seek solutions through new management practices in order to become more efficient. A alternative to these management practices is known as Lean Construction which is derived from the Toyota System Production. Lean Construction main goals are to reduce parts of activities that do not add value, increase product value by considering customer needs, reduce variability and production cycle time, simplify process by reducing the number of parts or steps, increase the flexibility in the product execution and transparency process, focus the control on overall process, introduce continuous improvement process, maintain a balance between improvements in flows and conversions and seek to learn from practices adopted by competitors. However, the construction industry is characterized by having nomadic activity, which undertakes an unique product with high cost of production and big inertia for behavioral change, making it difficult to implement the philosophy of lean construction in companies. In this sense, the main objective of this study is to develop a methodology for implementation of the principles of Lean Construction. The method of implementing the proposed management system was designed with the aid of 5W2H tool, and the implementation process is divided into three phases. The first one aims to know in a macro way the current operation of construction, identify who is its target audience and what are the products and services offered to the Market. The second phase aims to describe what actions should be taken and which documents are needed to be created or modified; finally, the third step goal consists in how to control and monitor established processes, where through Strategic Planning the company goals would be set along with their respective targets and indicators in order to keep the system working, aiming for continuous improvement with focus on the customer. This methodology was conceived as a case study analyzing a medium size construction with more than 18 years of activity and certified for almost 10 years with ISO9001 and level A in PBQP-H. We also conclude that this implementation process can be used in any developer and / or builder

Uma contribuição à definição de indicadores de desempenho de instituições federais de educação tecnológica do Brasil na abordagem do balanced scorecard

This Master of Science Thesis deals with a study on applying the BSC Balanced Scorecard to assess the performance of Federal Centers for Technological Education Institution in Brazil, the CEFET s (Centro Federal de Educação Tecnológica), government organizations non for profit. It s accomplished a literature review in order to understand the BSC and its application to non for profit organizations and as a main result it is proposed a BSC conceptual model with an inversion of the main BSC perspective from financial to customer/society. Taking the FORPLAN/CONCEFET performance indicators matrix it is developed a set of performance indicators for the two tops perspective in the conceptual model proposed five for customer/society perspective and three for financial/budget perspective. A field survey with ten CEFET s General Directors is conducted to validate the indicators and assess the perception of the Directors on the hierarchy of the conceptual model, and a hierarchy among the indicators as well. The main results suggests that the indicators are validated, that most of the Directors support the hierarchy presented in the conceptual model but 30% of them have a traditional model with financials coming first. In terms of indicator hierarchy, there s a slight priority for the student unitary cost among the financial perspective indicators, and a relative balance among the customer/society perspective indicators

Avaliação dos indicadores de desempenho de instituições federais de educação tecnológica doBrasil na abordagem do balanced scorecard

This Master of Science Thesis deals with a study on applying the BSC Balanced Scorecard to assess the performance of Federal Institution for Technological Education Institution in Brazil, a government organizations non for profit. It s accomplished a literature review in order to understand the BSC and its application to non for profit organizations and as a main result it is proposed a BSC conceptual model with an inversion of the main BSC perspective from financial to customer/society. It is used the annual management report of thirteen Institutions and applied a Pearson correlation analysis in order to verify a cause-effect situation between indicators. The main findings suggest that the model teachers qualification in terms of degree earned, quantity of teachers in full time job, and rate of students by teacher in full time job having good pearson correlation with the results expected of quality, throughput, social and demand response. However, the student unit cost use as the sole financial indicator did not get any reasonable correlation with the results, as so the quality and quantity of books in the libraries. Although it suggests a need for improvement in the model, the general model adopted appears to be satisfactory as a starting point to a BSC-like performance measuring system to this kind of Institutions

Segurança Alimentar e Controle de Qualidade: um estudo da implantação do Programa Alimentos Seguros em supermercados de bairro

This study aimed to analyze the percentage of compliance, related to the requirements of Practice, achieved by 23 supermarkets in neighborhood after the deployment of Food Insurance Program. For its development research methodology adopted was the application start and end of a check-list (tool-specific SBP) in 23 supermarkets, target of this study. After the deployment of PAS was made a comparative study where it was possible to see that these companies need to improve conditions related to food safety, because according to the study, none of the 23 supermarkets evaluated met the criteria recommended by the SBP to 100% of compliance for the items critical of the check-list. Only 04 of the 23 supermarkets were in the range of 80 to 90% of the overall percentage of compliance, representing only 17.3% of the sample. Most of the sample submitted in a regular situation, according to the methodology of Cardoso (2001). Of the 23 supermarkets studied, 03 supermarkets were classified as poor (13.04%), 13 as scheduled (56.52%) as good and 07 (30.43%). You can see improvements in a small part of the sample, but the decline in the percentage of compliance of 02 companies after working for the implementation of the program, showing lack of responsibility and commitment of companies which should have as its top priority to food safety that market

Diagnóstico para implantação do sistema de gestão ambiental em postos revendedores de combustíveis no município de Paranamirim RN: um estudo de caso

natural resources that still enjoy, in the certainty that if we do not, could culminate at the end of that remains. The environmental contamination by fuels in the retail service of oil and biofuels, has been a subject of growing research in Brazil, due to the large pollution potential of this activity. The aim of this study was to evaluate the importance of implementing the Environmental Management System (EMS) in fuel retail service stations in the city of Parnamirim-RN, but also describe the current situation the same as licensing and environmental characterization; identify existing barriers to implementation of EMS on the costs, technologies, knowledge, vision, present the potential benefits for the implementation of the EMS (social, economic and environmental), to identify the existence of plans for future action to implement the EMS , as a subsidy to promote the implementation of it. The methodology was developed through analysis of documents provided by the environmental agency responsible for licensing of retail service stations and fuel pala ANP. For data collection, we used the questionnaire was applied directly to managers or managers of sub-stations. Data were collected in 12 of 30 posts in the municipality. For purposes of data treatment was performed a descriptive analysis with respect to the opinion of twelve managers (respondents). The data acquired, according to the Likert scale were tabulated and analyzed using software SPSS 17.0 and Excel 2003, it was generated tables and graphs to observe the behavior of the data. The results showed that most respondents have a schooling level higher (58.3%) of the jobs surveyed 50% work on average 6 to 10 years and 41.6% are in operation for over 11 years , 75.0% do not have a license to operate and 12 stations, 58.3% were sued for not having a license to operate and are therefore in full commercial activity, 83% of jobs have some practice environmentally responsible, 75% agree in making planning future action to implement 8 the EMS in their ventures, 70% in full agreement that the high cost is a form of impediment to implementation of EMS; 66.67% agreed that resistance to change is an impediment to implementation of EMS; 90.91% agreed that the implementation of EMS is very complex, 80% of respondents agreed in a very significant environmental legislation is also a key factor preventing the implementation of EMS is noteworthy that 100% of respondents agreed that the knowledge about the use of the EMS will help to solve environmental problems in the fuel retail service stations, the implementation of the EMS will benefit with increased efficiency of resources applied to the findings by the agreement of 91.66% of respondents, where only 8, 33% disagreed, there was also a percentage of 100%, agreed that the company's image will be a great benefit, but also a contribution to solving environmental problems in the fuel retail service stations. Thus, the importance of the implementation of EMS in the fuel retail service stations in the city of Parnamirim-RN, with an urgent need to be deployed.

Avaliação da importância dos sistemas de gestão da qualidade nas universidades federais

This thesis aims at analyzing from the perspective of the manager the importance of the use of quality management tools and concepts in Federal Universities. It was motivated by the following research problem: do Federal University managers consider it to be relevant the quality management in their institution? Therefore, we sought to gather evidence for a satisfactory approach that addresses the complexity of the topic researched: quality, higher education and quality management systems. We chose to adopt an applied study, the exploratory-descriptive research as to the objective and the quantitative and qualitative research as to the approach to the problem. The object of study is composed by the Planning Provosts of Federal Universities listed in the University Ranking Sheet - (RUF) in 2013. We chose to restrict the sample listing only the provosts of the 20 best-placed universities in the ranking of the Federal Universities. The research instrument was composed of 26 questions, of which 6 questions were designed to identify the profile of the manager, 16 questions of perception (manifested variables) on the importance of quality management in the University, where the managers assigned values (answers) to the affirmatives (that address the main topic of this thesis) based on a Likert scale of 5 points, and 4 open and optional questions, in order to identify general management practices used. It was used for statistical analysis (data analysis) descriptive and factorial statistics. The responses collected through the questionnaire portray the managers´ perception regarding the importance of quality management in their institutions. Sixteen variables were addressed, the results of factor analysis of importance were "Important" and "Very Important", where the variable (V2) was "Important" and all others "Very important." With this information, it is possible to prioritize some areas that deserve immediate action. As it was observed that some variables are "Very important" for the vast majority of managers, others did not show the same result as example (V2, V10, V11). It is concluded that the manager´s perception of quality management in his or her institution is relevant, but the same importance is not given to quality programs implemented in other segments of the economy, and that, despite the advancements offered by SINAES, the model does not evaluate the institution in a global way. Thus, with the results, it is expected to contribute to the advancement of the subject, trying to arouse interest from the managers of Federal Universities in the subject, emphasizing the importance of quality management systems as a necessary tool to raise the institutional quality

Implantação de um sistema de detecção de vazamentos em oleodutos com tratamento de alarmes falsos

The pumping of fluids in pipelines is the most economic and safe form of transporting fluids. That explains why in Europe there was in 1999 about 30.000 Km [7] of pipelines of several diameters, transporting millíons of cubic meters of crude oil end refined products, belonging to COCAWE (assaciation of companies of petroleum of Europe for health, environment and safety, that joint several petroleum companies). In Brazil they are about 18.000 Km of pipelines transporting millions of cubic meters of liquids and gases. In 1999, nine accidents were registered to COCAWE. Among those accidents one brought a fatal victim. The oil loss was of 171 m3, equivalent to O,2 parts per million of the total of the transported volume. Same considering the facts mentioned the costs involved in ao accident can be high. An accident of great proportions can bríng loss of human lives, severe environmental darnages, loss of drained product, loss . for dismissed profit and damages to the image of the company high recovery cost. In consonance with that and in some cases for legal demands, the companies are, more and more, investing in systems of Leak detection in pipelines based on computer algorithm that operate in real time, seeking wíth that to minimize still more the drained volumes. This decreases the impacts at the environment and the costs. In general way, all the systems based on softWare present some type of false alarm. In general a commitment exists betWeen the sensibílity of the system and the number of false alarms. This work has as objective make a review of thé existent methods and to concentrate in the analysis of a specific system, that is, the system based on hydraulic noise, Pressure Point Analyzis (PPA). We will show which are the most important aspects that must be considered in the implementation of a Leak Detection System (LDS), from the initial phase of the analysis of risks passing by the project bases, design, choice of the necessary field instrumentation to several LDS, implementation and tests. We Will make na analysis of events (noises) originating from the flow system that can be generator of false alarms and we will present a computer algorithm that restricts those noises automatically

Caracterização física do solo e desempenho operacional de máquinas agrícolas na implantação da cultura do sorgo forrageiro

Forage sorghum can be grown in areas presenting dry and hot environmental situations where the yield of other grasses can often be uneconomical. The objective of this study was to analyze the operating performance of agricultural machines in the deployment of sorghum forage in four tillage systems, as follows: no-tillage system, disk harrow + seeding, disk harrow + two light disking + seeding, minimum tillage + seeding and four seeding different speeds, as follows: 3, 5, 6 and 9 km h(-1). The study was performed under field conditions in FCA/UNESP, Botucatu County, SP, Brazil. The data were subjected to variance analysis in a simple factorial 4 x 4, and a random block design with split plots. Operational performance of the agricultural machinery, physical characteristics the soil, its water content and the yield of dry matter and green sorghum were determined. The operational performance of agricultural machines in the deployment of sorghum forage is influenced by the sowing speed and the soil tillage system used. Chisel plow was the equipment that required the highest mean traction force, mean traction and slip, as well as the lowest mean speed for the studied tillage system. Forage sorghum showed higher yields in no-tillage systems at a seeding speed of 5 km h(-1).

Implantação de Reservas Legais: uma nova perspectiva na conservação dos recursos naturais em paisagem rural

According to the Forest Code of 1965, it is mandatory that every rural property destine part of its land to the establishment of Legal Reserves. When a diagnosis is made over all Brazil, the reality is quite different from what is demanded by law. Therefore, this work, as a general objective, proposes ways of establishing Legal Reserves based on the analysis of the environmental deterioration in a river basin. For this purpose, the environmental deterioration was detected based on three diagnoses: physical-conservational, socioeconomical, and environmental quality. In this way, from a quantitative and qualitative diagnosis, it was possible to identify the main aggressive factors in the studied river basin and to indicate the main vulnerabilities that the area is subjected. According to such diagnosis, some proposals for the establishment of Legal Reserves are discussed here based on scientific arguments aimed at the conservation of water resources, soil and biodiversity. It is hoped, that from this study, the environment receives a new tool for diagnosis, pollution control, recovery and conservation of natural resources.

Produção de fitomassa e acúmulo de nutrientes pela aveia-preta em função da aplicação de calcário e gesso em superfície na implantação do sistema plantio direto

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Nutrição e produtividade de grãos da aveia-preta em função da aplicação de calcário e gesso em superfície na implantação do sistema plantio direto

A nutrição e produtividade das culturas podem ser afetadas pelas modificações químicas do solo causadas pela calagem e aplicação de gesso em superfície. Este trabalho objetivou avaliar o efeito da aplicação de calcário e gesso em superfície, na implantação do sistema plantio direto, sobre a nutrição e a produtividade de grãos da aveia-preta, em região de inverno seco, em área anteriormente utilizada com preparo convencional. O experimento foi realizado durante 2003 e 2004, em um Latossolo Vermelho distroférrico, em Botucatu (SP). O delineamento foi de blocos casualizados com parcelas subdivididas e quatro repetições. As parcelas (18,0 x 5,4 m) foram constituídas por quatro doses de calcário dolomítico (0, 1.100, 2.700 e 4.300 kg ha-1), com PRNT = 71,2 %, e as subparcelas (9,0 x 5,4 m) pela aplicação ou não de 2.100 kg ha-1 de gesso agrícola. O aumento no teor de Ca no solo, provocado pela aplicação de calcário e gesso, diminuiu o teor de Mg na folha bandeira da aveia-preta em ano com deficiência hídrica. A aplicação de calcário em superfície aumentou os teores de K e reduziu os de Cu e Fe, e a aplicação de gesso agrícola aumentou o teor de S na folha bandeira da aveia-preta. A calagem em superfície aumentou a produtividade de grãos da aveia-preta, em ano com deficiência hídrica, com efeitos mais pronunciados na presença de aplicação de gesso.
