Otimização do processo de MRP (Material Requirement Planning) de embalagens: uma aplicação da metodologia lean six sigma em uma indústria de agronegócios

There is a growing search for continuous improvement within the companies which creates an obligation of reducing and when it is possible eliminating waste. Production Planning and Control Department (PCP) is not out of this question, making necessary the application of methods and creation of tools that eliminate steps which do not add value to the planning process. This paper aims to develop a tool which concentrates in just one place all the necessary information to make the packaging material requirement planning (MRP) in a agribusiness company. Besides, it also aims, in a more visual way and using devices that prevent mistakes (Poka-Yoke), to reduce the number of reviews and mistakes made by analysts. As a result, an Excel spreadsheet was developed. This spreadsheet shows what happens with the status of planning and receiving of packaging, giving some advices when some critical situation happens. The use of Lean Manufacturing Method and the action research method helped to well define the problem and to reduce the number of steps, spreadsheets and time of process in 80%, 60% and 75%, respectively

Carne Bovina: Produtividade Vs Qualidade

Bovine meat exerts an important contribution to the human diet, mainly by its high biological value. For this reason the productivity and the quality of beef are so discussed. Productivity is defined as the ratio between production and the factors of production used and quality defined as an adjective given to the product that suits the consumer implicit and explicit. Brazil is the world leader in tonnage exported bovine meat, however the country has a relatively low income, since no exports to the markets of greater added value. Quantify the degree of importance of these two factors in a capitalist market is not easy, so knowing the science that involves this product is vital for both factors. We must know that there is a wide variability in the markets importers and Brazil should seek to be the leader everywhere, whether carcass with better conformation and degree of finish, is lean beef, organic meat is even

Implementação da metodologia lean manufacturing em uma linha de produção por meio de certificação interna

To the companies maintain competitive in the market, they need continuous improvement in quality and productivity. This continuous improvement can be achieved through lean manufacturing tools. The idea of lean manufacturing is to map the flow to identify the processes that don’t add value in the final product, according the customer specification, in others words is eliminate or reduce the waste on the production flow. However the implementation of lean manufacturing is not so simple and involves the resistance of the employees, lack of training and the lack of knowledge to make the implementation. The objective of this study is determinate the good practices and difficulties found by a multinational company in the field of healthy that aims implementing the Lean Manufaturing through an internal certification. The methodology used to approach the problem is a case of study that analyzes the information introduced through discussion made by a semi structured interview. The case study describes the steps to get the certification, involving the concepts of 5S, balancing, standardization and routine management. The literature and the study case showed that the good practices, such as productivity increases, safety level increases and the machine stability were accomplished, but the majority difficulties was found in cultural factors and planning. Some recommendations were proposed to the others companies, such as the elaboration of a qualification matrix and the review of the activities chronogram during the implementation. The way that the company found to implement Lean Manufacturing concepts was a creative method to show to everybody the objective and the target to be accomplished and is one way to recognize the effort through the certification

Aumento de produtividade em uma célula produtiva com processo de usinagem utilizando conceitos Lean

In the current competitive and global scenario, companies in search for solutions that become the production every time more efficient is increasing and at the same time cost reductions and cost eliminations are becoming increasingly evident and needed. In an attempt to improve production, this work aims to compare benefits obtained using principles of philosophy Lean Manufacturing in an productivity growth of a cell from an auto parts sector industry.

Fatty acid profile and meat quality of young bulls fed ground soybean or ground cottonseed and vitamin E

The objective of this study was to evaluate the fatty acid profile and qualitative characteristics of meat from feedlot young bulls fed ground soybean or ground cottonseed, with or without supplementation of vitamin E. A total of 40 Red Norte young bulls, with an initial average age of 20 months, and an initial average BW of 339 +/- 15 kg, were allotted in a completely randomized design using a 2 x 2 factorial arrangement, with two oilseeds, and daily supplementation or not of 2500 IU of vitamin E. The experimental period was for 84 days, which was preceded by an adaptation period of 28 days. The treatments were ground soybean (SB), ground soybean plus vitamin E (SBE), ground cottonseed (CS) and ground cottonseed plus vitamin E (CSE). The percentage of cottonseed and soybean in the diets (dry matter basis) was 24% and 20%, respectively. Diets were isonitrogenous (13% CP) and presented similar amount of ether extract (6.5%). The animals were slaughtered at average live weight of 464 +/- 15 kg, and samples were taken from the longissimus dorsi muscle for the measurement of fatty acid concentration and the evaluation of lipid oxidation and color of the beef. Before fatty acid extraction, muscle tissue and subcutaneous fat of the longissimus dorsi were separated to analyze fatty acid profile in both tissues. Supplementation of vitamin E did not affect fatty acid concentration, lipid oxidation and color (P > 0.05). Subcutaneous fat from animals fed CS diet had greater C12: 0, C16: 0 and C18: 0 contents (P < 0.03). In addition, CS diets reduced the C18: 1 and C18: 2 cis-9, trans-11 contents in subcutaneous fat (P < 0.05). The muscle from animals fed CS tended to higher C16: 0 and C18: 0 contents (P < 0.11), and decreased C18: 1, C18: 2 cis-9, trans-11 and C18: 3 contents (P < 0.05) compared with SB. The Delta(9)-desaturase index was greater in muscle from animals fed SB (P < 0.01). At 42 days of age, meat from cattle fed SB had a greater lipid oxidation rate (P < 0.05). Meat from animals fed SB diets had less lightness and redness indices than meat from animals fed CS diets after 14 days of age. In conclusion, the addition of ground cottonseed in the finishing diets did increase the saturated fatty acid content of the longissimus dorsi. However, animals fed cottonseed exhibited greater lightness and redness of beef. In this study, the addition of vitamin E did not affect qualitative characteristics of meat.
