Silosuotų pašarų kokybės įtaka karvių produktyvumui ir produkcijos kokybei / The influence of quality ensiled forage on the productivity of cows and production quality

Visockas, Edvinas 26 April 2013 (has links)
Darbo tikslas: nustatyti karvėms šertų silosuotų pašarų kokybinius rodiklius, pašarų įtaką melžiamų karvių produktyvumui ir pieno kokybei. Įvertinti racionų ekonominius rodiklius. Darbo uždaviniai: įvertinti melžiamų karvių silosuotus pašarus ir racionų struktūrą. Išanalizuoti silosuotų pašarų kokybės rodiklius. Nustatyti raciono įtaką karvių produktyvumui ir pieno kokybei. Karvių šėrimo racionų ekonominio įvertinimo analizė. Pateikti išvadas ir pasiūlymus. Tyrimui medžiaga rinkta Jonavos raj., X ūkyje. Išanalizavus X ūkio 2011–2012 metų karvėms šertų silosuotų pašarų kokybę, karvių šėrimo racionų sudėtį, maistingumo rodiklius, galima daryti išvadas: žemės ūkio bendrovės karvių banda atitinka vidutinius produktyvumo rodiklius auginant Lietuvos juodmargių veislės karves. Karvės šeriamos viso raciono pašarų mišiniais. Karvėms racionai sudaromi atsižvelgiant į laktacijos tarpsnius, pagal kuriuos karvės suskirstytos į tris grupes. Racionai nekito per analizuojamuosius metus. Išanalizavus silosuotų pašarų kokybės įtaką karvių produktyvumui, galima teigti, kad racionai ūkyje yra subalansuoti. Atlikus pieno tyrimus, 2012 metais, nustatytas 10,07 proc. didesnis tirtų karvių pieno riebumas., lyginant su karvių pieno riebumu 2011 metais. Karvių pieno riebumas 2011 metais buvo 4,17 proc, o 2012 metais 4,59 proc. Pieno baltymingumas tiriamaisiais metais nekito ir išliko per visą tyrimo laikotarpį 3,48 proc. Laktozės kiekis piene: 2011 metais – 4,34 proc., o 2012 metais 4,4 proc. arba 1...

The task of the work: to assess the silage used to feed dairy cow and their rations’ structure. To analyze the ensiled forage quality indicators. To set the ration influence on cows’ productivity and milk quality. Economic evaluation analysis of cows’ rations. The conclusions and suggestions. The material for the research was collected in Jonava agricultural company X. The analysis of an X during 2011-2012 ensiled forage used to feed cows quality, cows’ feeding ration composition, nutritional indicators, conclusions can be drawn: agriculture company’s average cow herd suits the productivity indicators of Lithuanian Black and White cows. The cows are fed rations of feeding mixtures. Cows’ rations are drawn up on the stages of lactation, by which cows are divided into three groups. Diets did not change during the surveyed year. The analysis of ensiled forage quality on milk production of cows, it can be said that the farm’s rations are balanced. After the milk testing in 2012, it was established, that compared to 2011 (4.17 percent) milk fat content grew of 10,07 percent (4.59 percent in 2012). Milk protein under investigation didn’t change and remained at 3.48 percent. The quantity of lactose: 2011 - 4.34 percent, 2012 - 4.4 percent. Somatic cell count increased in 2012 to 458...

Development of a supplier quality assessment system in Eskom

Fleshman Muller, Eunamia 04 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Eskom, the South Africa and trans-Africa electrical power utility, has a capacity expansion project that is estimated to cost roughly R340 billion. The programme is anticipated to continue through 2018. Eskom will be contracting with a multitude of suppliers and it is imperative that the projects delivered under the capacity expansion programme meet Eskom’s required quality standards. The question then arises whether the set quality standards are sufficiently comprehensive to provide confidence that suppliers will achieve high quality standards. This aim of this research was to examine supplier assessment programmes to determine the criteria that will best provide supplier assurance. The researcher consulted a vast range of literature available on supplier quality assessment programmes. From the literature consulted, there appeared to be some recurring themes from the range of assessment tools. It also becomes apparent that the assessment tool cannot only focus on a quality system, but a balance of strategic and operational focus was needed to fully understand suppliers’ ability to deliver. One of the key considerations was establishing longer-term collaborative relationships with key suppliers. Long-term relations encourage trust, transparency and innovation. It was equally important to ensure that operational assessments provided insight on suppliers’ capability. Based on the literature reviewed, a proposed framework was tested against the current methodology for supplier evaluation. From these comparisons, some gaps were identified and recommendations were suggested to improve the supplier evaluation programme.

Orientador: Irany de Andrade Azevedo / Dissertação (mestrado profissional) - Universidade Estadual de Campinas, Faculdade de Engenharia Mecânica / Made available in DSpace on 2018-08-18T23:07:14Z (GMT). No. of bitstreams: 1 Martins_TalesRibeiro_M.pdf: 3049449 bytes, checksum: 5570470f66bfb2bcc9e6231e02e25dd5 (MD5) Previous issue date: 2011 / Resumo: As empresas do ramo automotivo costumam empregar testes de durabilidade para confirmar o atendimento das especificações estabelecidas em projeto, já que existe a necessidade de garantia da qualidade do produto a ser comercializado. No trabalho é realizada uma estimativa da confiabilidade de um motor diesel na fase de desenvolvimento com o uso de uma ferramenta de gerenciamento de crescimento da confiabilidade. São apresentados os conceitos essenciais para a estimação do valor da confiabilidade e de seu crescimento, o processo típico de desenvolvimento do produto e seu ciclo de vida no mercado. É descrito o procedimento atualmente realizado por uma empresa do ramo automotivo com grande participação no mercado brasileiro e internacional, são descritos os testes de validação usados, e é apresentada uma proposta de melhoria no modelo atual. A proposta consiste em classificar as falhas encontradas no decorrer dos testes, identificar os sistemas mais suscetíveis à falha nas condições de uso previstas, e utilizar uma ferramenta de software baseada no modelo AMSAA-CROW para estimar o crescimento da confiabilidade, com base no MTBF e no parâmetro de forma â. A curva de crescimento da confiabilidade gerada indica a evolução do desenvolvimento até o objetivo a ser atingido. Com os dados de falhas identificadas no decorrer do desenvolvimento é plotada a curva de evolução da confiabilidade ao longo da fase de desenvolvimento. O modelo proposto possibilita a verificação, ao longo do período de desenvolvimento do produto, da eficácia das ações corretivas. Permite, ainda, determinar se a confiabilidade especificada para o produto já foi atingida e se a quantidade de recursos alocados ao desenvolvimento é suficiente. Os dados obtidos ao longo do processo permitem a formação de um banco de dados padronizado a ser usado em outros desenvolvimentos / Abstract: Automotive companies involved in diesel engines development often use durability tests to confirm the achievement of the specifications established in a project, aiming to build the desired level of quality in a product being marketed. In this work a software based tool is used to estimate the reliability growth evolution trough engine development phase. The essential concepts for the estimation of the value of reliability and of its growth, the typical process of product development and its life cycle in the market are considered. A procedure currently performed by an automotive company with significant market share in Brazil and abroad and the validation tests it uses is described. A new procedure is proposed aiming to improve the current model through development time reduction and early failures identification and correction. It consists in classifying the failures found during testing, identifying the systems more susceptible to failure in the conditions specified during operation, and applying a software tool based on the Crow-AMSAA model to estimate the reliability growth, based on the MTBF and the shape parameter â. The reliability growth curve is generated using the desired goal at the end of development, predicting the evolution of reliability throughout the development phase. The proposed model enables evaluation of the effectiveness of corrective actions; it is a tool that can be used to judge if the reliability goal has been reached and if the resources allocated to development are enough. The data obtained during the process allow the formation of a standardized database to be used in future developments / Mestrado / Projetos / Mestre em Engenharia Automobilistica
