Breeding objectives in the turkey industry are heavily weighted towards improving growth traits. This thesis focused on methods to efficiently select for other important production traits such as reproduction, feed efficiency, and meat yield. Based on bivariate and random regression modeling it was determined that egg production, fertility, and hatchability were influenced by genotype by environment interactions and, as a result, the regulation of reproductive traits is by some unique genes in the summer and winter. This may be due to changes in day length and temperature. Feed efficiency is another important consideration in a breeding objective and feed conversion ratio and residual feed intake were both moderately heritable. Residual feed intake was also more independent of production traits than feed conversion. Feed intake, body weight, and weight gain were moderately heritable and progress can be made in feed efficiency by appropriately weighting these traits in an index. Infrared measures of surface temperature were then investigated to determine if they can be used to select for feed efficiency. Temperatures of the distal metatarsus, eye, neck, and head did not show a strong relationship to feed efficiency and therefore offer limited advantages to a breeding program. Selection for breast meat yield (BMY) is important and it was determined that breast muscle depth, measured with ultrasound technology, is heritable and highly correlated to the carcass trait. As a result, ultrasound traits can compliment conformation scoring and sibling testing in a breeding program to increase the accuracy of selection for BMY and increase response to selection. A deterministic model was also developed and could be used to determine optimum slaughter weight. This would optimise profits in an integrated system, enabling the industry to account for and capitalize on genetic gains. Overall, the population parameters and selection criteria identified for reproduction, efficiency, and meat yield traits identified in the present thesis could be used to increase selection efficiency in turkey breeding programs. Further, the developed production model can be used by the industry to slaughter turkeys at a time that maximizes profits, based on performance levels.

Mathematical modeling in animal agriculture can be applied at various levels including at the tissue, organ, animal, farm, regional and global levels. The purposes of this research were i) to evaluate models used to estimate volatile fatty acid (VFA) and methane (CH4) production and assess their impact on regional enteric CH4 inventory, and ii) to develop a process-based, whole-farm model to estimate net farm GHG emissions. In the first study, four VFA stoichiometric models were evaluated for their prediction accuracy of rumen VFA and enteric CH4 production. Comparison of measured and model predicted values demonstrated that predictive capacity of the VFA models varied with respect to the type of VFA in rumen fluid which impacted estimated enteric CH4 production. Moving to a larger scale assessment, we examined the enteric CH4 inventory from Manitoba beef cattle (from 1990 to 2008) using two mechanistic rumen models that incorporate VFA stoichiometric models: COWPOLL and MOLLY, and two empirical models: Intergovernmental Panel on Climate Change (IPCC) Tier 2 and a nonlinear equation (Ellis). The estimated absolute enteric CH4 production varied among models (7 to 63%) indicating that estimates of GHG inventory depend on model selection. This is an important consideration if the values are to be used for management and/or policy-related decisions. Development of models at the individual farm component level (animal, soil, crop) does not accurately reflect net GHG emissions generated from the whole production system. We developed a process-based, whole-farm model (Integrated Components Model, ICM), using the existing farm component models COWPOLL, manure-DNDC and some aspects of IPCC to integrate farm components and their associated GHG emissions. Estimates of total farm GHG emissions and their relative contribution using the ICM were comparable to estimates using two other whole-farm models (Integrated Farm System Model and Holos model). Variation was observed among models both in estimating whole-farm GHG emissions and the relative contribution of the different sources in the production system. Overall, whole-farm models are required to explore management options that will mitigate GHG emissions and promote best management practices. However, for full assessment of the production system, other benefits of the system (e.g., carbon sequestration, ecosystem services), which are not part of current whole-farm models, must be considered.

A primary role of the Incident Command System is to learn from past incidents, as illustrated by its origins in the wildland firefighting community. Successful emergency response operations under the Incident Command System has prompted its nationwide spread, this promulgation critically relies on the system’s capability to stabilize and continuously improve various aspects of emergency response through effective organizational learning. The objective of this study is to evaluate the potential to apply fundamental principles of the Toyota Production System (Lean manufacturing) to improve learning effectiveness within the Incident Command System. An in-depth review of literature and training documents regarding both systems revealed common goals and functional similarities, including the importance of continuous improvement. While these similarities point to the validity of applying Lean principles to the Incident Command System, a focus on the systematic learning function of the Incident Command System culminated in the discovery of gaps in approaches proposed by the Incident Command System framework. As a result, recommendations are made for adjustments in systematic problem solving to adapt Lean principles of root cause analysis and emphasis on standardization of successful countermeasures to benefit the system. Future recommendations are also proposed based on the author’s understanding of the system.

To compete, manufacturing companies need production systems that quickly can respond to changes. To handle change drivers such as volume variations or new product variants, reconfigurability is advocated as a competitive means. This implies an ability to add, remove, and/or rearrange the structure of the production system to be ready for future changes. Still, it is not clear how the production system design process can capture and support the design of reconfigurable production systems. Therefore, the objective of this thesis is to increase the knowledge of how to support the design of reconfigurable production systems. Reconfigurability could be defined by a number of reconfigurability characteristics including convertibility, scalability, automatibility, mobility, modularity, integrability, and diagnosability. In eight case studies, reconfigurability characteristics in production system design were studied in order to investigate reconfigurability needs, knowledge, and practice in manufacturing companies. In three of the case studies reconfigurable production systems were studied to identify the links between change drivers and reconfigurability characteristics. In the remaining five case studies, reconfigurability in the production system design processes was addressed in terms of needs, prerequisites, and consideration. Based on the literature review and the case studies, support for reconfigurable production system design is suggested including two parts. The first part comprises support for analyzing the need for reconfigurability. Based on relevant change drivers the need for reconfigurability must be identified to enable selection of right type and degree of reconfigurability for each specific case of application. A comprehensive view of the reconfigurability characteristics is presented and links between change drivers and reconfigurability characteristics are described. The characteristics are divided into critical characteristics, that lead to a capacity or functionality change of the production system, and supporting characteristics, that reduce system reconfiguration time but do not necessarily lead to a modification of functionality or capacity of the production system. The second part provides support in how to consider reconfigurability in the production system design process. A holistic perspective is crucial to design reconfigurable production systems and therefore constituent parts of a production system are described. According to their character physical, logical, and human reconfiguration must be considered through the whole production system design process.

The companies have sought ever more efficient ways to organize to achieve their goals and, therefore, the search for a productive system that presents a good performance is one of important factors for the company to reach a stage really different efficiency. From this point of view, the main objective of this study is to develop a system for identifying production losses of small businesses in the garment sector Cianorte-Paraná, Brazil. Thus, from a survey of data from the factory floor, is intended to apply some tools of the Toyota Production System (STP) to suggest possible ways to eliminate waste and waste in the production process. Methodologically the research can be characterized as qualitative, quantitative and exploratory. For data collection visits were made to the company, where it was possible to maintain an informal dialogue with both the Production Engineer and with the staff directly involved with the production process and direct observation of the reality of the organization. The results show that the STP tools, mapping the value stream, identifies losses along the production process of the company, and, most importantly, the possibility of the production manager from this tool eliminate losses, tracing a new mapping, called future state, which relate opportunities for improvements in the production process, synchronized steps and leaving no gaps between them. / As empresas têm buscado maneiras cada vez mais eficientes de se organizar para alcançar suas metas e, para tanto, a busca por um sistema produtivo que apresente um bom desempenho é um dos fatores importantes para que a empresa atinja um estágio realmente diferenciado de eficiência. Sob este ponto de vista, o objetivo principal deste estudo é desenvolver uma sistemática que permita identificar as perdas de produção de empresas de pequeno porte do setor de confecções de Cianorte-Paraná, Brasil. Assim, a partir do levantamento de dados junto ao chão da fábrica, pretende-se aplicar algumas ferramentas do Sistema Toyota de Produção (STP) para sugerir possíveis caminhos para eliminar perdas e desperdícios no processo produtivo. Metodologicamente a pesquisa pode ser caracterizada como qualitativa, quantitativa e exploratória. Para a coleta de dados foram realizadas visitas à empresa, onde foi possível manter um diálogo informal tanto com o Engenheiro de Produção quanto com os funcionários diretamente envolvidos com o processo produtivo e observação direta da realidade da organização. Os resultados apresentados mostram que as ferramentas do STP, o mapeamento do fluxo de valor, permite identificar as perdas ao longo do processo produtivo da empresa, e, o mais importante, a possibilidade do gerente de produção a partir desta ferramenta eliminar as perdas, traçando um novo mapeamento, denominado estado futuro, onde se relacionam as oportunidades de melhorias no processo produtivo, sincronizados as etapas e não deixando folgas entre elas.

O município de São Lourenço do Sul está assentado sobre a Planície Costeira Sul-Brasileira e o Escudo Cristalino Sul-Rio-Grandense, localizado na “metade sul” do Rio Grande do Sul, a chamada metade desfavorecida do Estado, mas com um grande potencial natural para a agropecuária, extrativismo e o turismo. Ao mesmo tempo, essas atividades têm colocado em risco a natureza. Para tentar compreender a complexidade da relação sociedade-natureza aí existente, formulou-se a questão que norteou o desenvolvimento da pesquisa: quais os elementos na paisagem que potencializam e/ou inibem a implementação e a sustentação dos sistemas agrícolas no município de São Lourenço do Sul – RS. Consideraram-se como hipóteses da pesquisa: (1) os terroirs existentes hoje, foram construídos a partir de um referencial histórico; (2) alguns terroirs se afirmam como características do aprimoramento técnico e produtivo; (3) aconteceram modificações nos terroirs no contexto histórico do município; (4) nas unidades da paisagem há sinais de desestruturação do terroir da batata e surgimento de novos terroirs como o fumo. Através da observação criteriosa da paisagem é possível constatar e interpretar a dinâmica resultante da interação entre o potencial ecológico, a exploração biológica e a ação antrópica, conceitos trabalhados por Bertrand, Sotchava e Tricart, entre outros, e que foram usados como referencial teórico e metodológico da pesquisa, para a definição e interpretação das unidades da paisagem e seus terroirs. Cada uma das unidades da paisagem e os seus terroirs representam uma porção local, com dinâmica e funcionamento diferenciados, relacionando elementos da morfologia da paisagem e a ocupação do território através dos seus sistemas produtivos, em estreita relação com o contexto histórico, abordagem usada por Deffontaines. A coleta de dados constou de observação dos indicadores visuais como a ocupação, as práticas, as estruturas, as relações e as formas de apropriações, de entrevistas com agricultores e informantes-chave do município, da análise documental, de fotografias e do mapeamento do meio físico. Como resultado foi produzido o Perfil e o Mapeamento das Unidades da Paisagem de São Lourenço do Sul, distinguindo as seguintes unidades de paisagem e terroir: Unidade de Paisagem Planície (terroir do arroz), Unidade de Paisagem Colinas (terroir da soja e milho e gado leiteiro), Unidade de Paisagem Colinas/Domos (terroir da batata, feijão e fumo) e Unidade de Paisagem Domos/Platôs (pecuária extensiva), que apresentam características originais e se manifestam em escala variadas de observação. Pode-se verificar a estreita relação do contexto histórico na construção e na modificação das unidades de paisagem e terroirs, resumida em três momentos distintos: a colonização pelos portugueses, a imigração dos pomeranos e a modernização da agricultura; e também a desestruturação do terroir da batata e o surgimento do terroir do fumo. / The municipality of São Lourenço do Sul is situated upon the Coastal Plain in southern Brazil and the Crystalline Shield at the south of the Rio Grande do Sul, a region which is known as the disfavored area of the state, but with a natural potential for agriculture, livestock, extraction and tourism. At the same time, those activities have put in risk the nature. For trying to understand the complexity of the society-nature relationship, which exists there, a guiding question has been formulated in order to develop this research: which are the elements of the landscape that strength and/or inhibit the implementation and sustenance of the agricultural systems within São Lourenço do Sul. It has been considered the following hypotheses: (1) the nowadays terroirs have been constructed from a historical reference; (2) some terroirs are confirmed as characteristics coming from their technical and productive enhancement; (3) there have been some changes on the terroirs that have occurred within the historical context of the municipality; (4) inside the lanscape units there are some signals of distructuring within the terroir of potato and the emergence of new terroirs like tobacco. Through a critical observation of the landscape, it is possible to prove and make interpretations about the dynamisms that resulted from the interaction among the ecological potential, the biological exploration and the anthropic action, concepts which are worked by Berthand, Stchava and Tricart, among other authors, and were used as theoretical and methodological reference of research, for defining and interpreting the landscape units and their terroirs. Each one of the landscape units and their terroirs represent a local portion, with differentiated dynamisms and functioning, relating elements of landscape’s morphology and the occupation of the territory throughout their productive systems, in a stretched relationship with the historical context. It’s an aproache used by Deffontaines. The collected data comprised the observation of visual indicators such as occupations, practices, structures, relationships and forms of appropriation; the interviews with farmers and key informants, the documental analysis, pictures and the mapping of the physical area. As a result, it has been produced a Profile and a Mapping, distinguishing the following landscape units and terroirs: Plain Landscape Unit (terroir of rice), Hill Landscape Unit (terroir of soya, maize and milked cows), Hill/Dome Landscape Unit (terroir of potato, beans and tobacco) and Dome/Plateau Landscape Unit (extensive livestock); which show original characteristics and are manifested in various scales of observation. It could be verified the stretched relationship of the historical context during the construction and modification of the landscape units and terroirs, which are summarized in three moments: the colonization by Portuguese, the Pomeranian immigration and the modernization of agriculture; and also, the distructuring of the terroir of potato and the emergence of the terroir of tobacco.

For this purpose, 226 farms visited and applied a questionnaire where blood of 2.692 apparently healthy sheep collected. In the present study, a mean prevalence in the northeast of 60,62% (137/226) of positive animal properties and 26,52% (714/2.692) of seropositive sheep. A mean VLA seroprevalence of 33,06% (162/490) in sheep and 82,93% (34/41) in the herds, with at least one positive animal observed in the state of CE. In AL, a seroprevalence of 2,55% was observed (7/275) from the animals and 21.74% (5/23) on farms. In the MA State, 64,13% (177/276) of the animals and 100% (23/23) of the herds were positive. Regarding the RN State, of the 33 properties surveyed, 12 (36,36%) had seroreagents and 16 of the animals studied (4,04%) were positive. In PB State, 2,82% (8/284) of the sheep were seroreagent and of the 24 farms analyzed, 2 (8,33%) presented a positive animal. In the PI, 76,98% (291/378) of the animals and all the properties (32/32) were seroreagent. In SE State, 894% (53/593) of the sheep were positive and 58,0% (29/50) in the sampled herds showed positivity. There was a significant association (p <0,05) regarding the sex, age and degree of kinship of the animals. The acquisition of animals for replacement of the herds (p <0,05) (odds ratio = 5,87, 95% CI = 2,06-16,76, p = 0,001) was identified as a risk factor for BTV in the evaluated states. In this study, the technological and sanitary aspects verified that the breeding system most adopted in the Northeast was the extensive (84,07%), with the activity directed mainly to meat (84,07%). It was verified that the animals were handled in sheepfolds on 68,14% of the properties. The predominance of joint rearing with goats and cattle was too observed. It was verified that 81,42% of the properties had some kind of technical assistance and that only 31,86% of the owners invest in their professional qualification of the employees. The most adopted practices on farms were cleaning the facilities (67,70%) and disposal of animals (80,09%). It was observed that 60,18% of the farms apply some type of vaccine. It was also observed that worm was the biggest problem faced in sheep farms (97,80%), and 96,02% of the producers used vermifugation as the control method. Other health problems frequently reported by the interviewees were Myiasis (93,83%), Caseous Lymphadenitis (89,87%), Pododermatitis (87,67%) and Bronchopneumonia (81,94%). The results obtained in this work indicate that the BTV is present in the sheep herds of the states analyzed and that the exploitation of these in the Northeast has low technological level. It was also verified that the control of the diseases of these states is deficient, which explains, in part, the low productivity of the herds / O escopo deste trabalho foi determinar a situação epidemiológica da infecção pelo vírus da Língua Azul (VLA) e caracterizar os aspectos tecnológicos e sanitários nos rebanhos ovinos dos estados de Alagoas (AL), Ceará (CE), Maranhão (MA), Paraíba (PB), Piauí (PI), Rio Grande do Norte (RN) e Sergipe (SE). Para tanto, foram visitadas e aplicados questionários em 226 propriedades, onde coletou-se o soro de 2.692 ovinos, aparentemente saudáveis. Observou-se uma prevalência média no nordeste de 60,62% (137/226) de propriedades com animais positivos e 26,52% (714/2692) de ovinos soropositivos. No CE houve uma soroprevalência média do VLA de 33,06% (162/490) nos ovinos, e de 82,93% (34/41) nas propriedades com pelo menos um animal positivo. Em AL, foi verificada uma soroprevalência de 2,55% (7/275) nos animais, e de 21,74% (5/23) nos criatórios. Já no MA, 64,13% (177/276) dos animais e 100% (23/23) dos rebanhos foram positivos. Em relação ao RN, das 33 propriedades pesquisadas, 12 (36,36%) tiveram sororreagentes e dos 396 animais estudados, 16 (4,04%) foram positivos. Na PB, 2,82% (8/284) dos ovinos foram sororreagentes e dos 24 rebanhos analisados, 2 (8,33%) apresentaram animal positivo. No PI, 76,98% (291/378) dos animais e todas as propriedades (32/32) foram sororeagentes. Em SE, 8,94% (53/593) dos ovinos foram positivos e nos rebanhos amostrados, 58% (29/50) apresentaram positividade. Houve associação significativa (p<0,05) quanto ao sexo, idade e grau de sangue dos animais. A aquisição (compra) de animais para reposição do plantel (p<0,05) (odds ratio = 5,87; IC 95% = 2,06-16,76; p=0,001) foi identificada como fator de risco para Língua Azul nos estados avaliados. No estudo dos aspectos tecnológicos e sanitários verificou-se que o sistema de criação mais adotado no Nordeste foi o extensivo (84,07%), com a atividade voltada majoritariamente para corte (84,07%), sendo verificado que os animais eram manejados em apriscos em 68,14% das propriedades. Foi observada a predominância de criação conjunta com caprinos e com bovinos. Verificou-se que 81,42% das propriedades possuíam algum tipo de assistência técnica e que apenas 31,86% dos proprietários investiam na qualificação profissional de seus funcionários. As práticas mais adotadas nas fazendas foram a limpeza das instalações (67,70%) e o descarte de animais (80,09%). Quanto à vacinação dos rebanhos, foi observado que 60,18% dos criatórios aplica algum tipo de vacina. Observou-se, também, que a verminose foi o maior problema enfrentado nos criatórios de ovinos (97,80%), sendo que 96,02% dos produtores utilizam como método de controle a vermifugação. Outros problemas sanitários frequentemente relatados pelos entrevistados foram a Miíase (93,83%), Linfadenite Caseosa (89,87%), Pododermatite (87,67%) e Broncopneumonia (81,94%). Os resultados obtidos neste trabalho indicam que o VLA encontra-se presente nos ovinos dos estados analisados e que a exploração destes no Nordeste possui baixo nível tecnológico. Verificou-se, também, que o controle das enfermidades destes estados é deficiente, o que explica, em parte, a baixa produtividade dos rebanhos / 2018-03-19

A produção de matérias-primas minerais é feita através de tecnologia conhecida mundialmente. No entanto, a crescente competição econômica mundial faz com que este domínio tecnológico não seja, por si só, suficiente para assegurar a sobrevivência das empresas de mineração. É necessário, também, que os métodos de gestão utilizados pela indústria de mineração estejam alinhados com a lógica da competitividade, visando maximizar os resultados econômicos financeiros das organizações como forma de sustentação no cenário globalizado atual. Esta tese está relacionada com a maximização dos resultados passíveis de serem alcançados nas indústrias de mineração, a ser obtida através de uma forma de gestão que integre a tecnologia intrínseca da Engenharia de Minas com a tecnologia de gestão da Engenharia de Produção. Esta integração é realizada através de um Modelo de Gestão Integrada, proposto nesta tese. A construção deste modelo teve como ponto de partida a experiência realizada pelo autor desta tese na mineração de fluorita no final dos anos 90, quando foram implementados alguns conceitos de Engenharia de Produção nesta atividade mineral.A partir desta experiência, sedimentada com a agregação de conceitos teóricos, foram selecionados três outros cenários na indústria de mineração para o desenvolvimento desta tese, nos quais foram utilizadas duas metodologias de pesquisa. Na mineração de calcário e na mineração de ametista, a Pesquisa-Ação foi a metodologia de pesquisa selecionada, enquanto que na mineração de carvão utilizou-se o Estudo de Caso. Na mineração de fluorita, a implementação de melhorias no processo de produção, devido à integração dos dois ramos da Engenharia considerados, resultou na redução dos gastos totais por tonelada de produto final, em função da eliminação de perdas no sistema de produção. A empresa transformou-se em uma organização de aprendizagem. Na mineração de calcário, a disseminação de conhecimentos da Engenharia de Produção através de processos de aprendizagem, propiciou o desenvolvimento de uma visão sistêmica do processo de produção por parte dos colaboradores, bem como a implementação de uma forma de gestão com o objetivo de otimizar o uso da capacidade existente. Neste cenário foi considerado, também, o desenvolvimento de novos produtos. Na mineração de ametista, o modelo de gestão proposto propiciou a realização de melhorias não somente no fluxo de produção, mas tambémna qualidade de vida dos trabalhadores devido à melhoria nas condições de trabalho desta atividade mineral. Na mineração de carvão, este trabalho procurou evidenciar a importância de se desenvolver novos produtos buscando a plena utilização da capacidade instalada. Neste cenário foram abordadas, também, questões relacionadas com o controle do meio ambiente. A análise e o estudo dos quatro cenários resultaram na construção de uma estrutura de mudanças e de um processo de mudanças para o Modelo de Gestão Integrada. A estrutura de mudanças do modelo é suportada pela integração das técnicas de lavra e beneficiamento mineral com as técnicas de gestão bem como pela inovação, que pode ser de produtos, serviços, métodos e mercado e, ainda, na forma de como é feita a gestão na Organização. Ela propicia a obtenção de melhores resultados nas organizações através da maior utilização dos ativos, com a ampliação do mercado, a redução dos custos operacionais e o aumento do lucro.O processo de mudanças do modelo tem início a partir da realização de um diagnóstico situacional para avaliar a sinergia existente na empresa entre os dois ramos da Engenharia considerados e tende a transformar a mesma em uma organização de aprendizagem para assimilação, integração e sedimentação dos conceitos, técnicas e ferramentas de Engenharia de Minas e de Engenharia de Produção. / Mineral raw material production is done through a well known worldwide technology. However, the technological domain seems to be insufficient to cope with the survival of mining industries in view of the increasing world economic competition. In addition, it is necessary that the management methods adopted by the mining industry be aligned with the logic of competitiveness aiming to maximize the financial and economic outcomes of the organizations as a way of supporting themselves in the current globalized scenario. This thesis deals with the maximization of outcomes to be achieved in the mining industries through a form of management that integrates Mining Engineering intrinsic technology with managing technology from Industrial Engineering. This integration is carried out through an Integrated Management Model proposed. The model was first devised by the author in the fluorspar mining in the late 90’s as some concepts from Industrial Engineering were being implemented. Drawing on the author’s experience, rooted in the aggregation of theoretical concepts, three other sites in the mining industry were chosen as a scenario for the work where two research methods were used. As for limestone and amethyst mining, the Survey-Action method was applied, while Case Study was used for coal mining. For fluorspar mining, the improvement in production based upon the integration of the Engineering areas resulted in a reduction of the total costs per ton for finished product, allowing the elimination of waste in such production system. The company became a learning organization. For limestone mining, the Industrial Engineering knowledge spread through learning steps provided a systemic view of the production process and implemented a management approach aiming to optimize the use of the existing capacity. In this setting, the development of new products was also taken into account. For amethyst mining, the management model provided improvements in the production flow and also improved the employee’s life quality due to better working conditions. In the last case study, coal mining, this work attempted to emphasize the importance of developing new products by using the company’s full capacity. In addition, issues related to environmental polution control were addressed. The analysis and study of the four scenarios led to the construction of a structure and a process of changes for the Integrated ManagementModel. The model changing structure is supported by the integration of mining and processing techniques with management through the innovation of products, services, methods and market. It provides better outcomes with the expansion of market share, operational costs reduction and higher profitability. The model changing process starts by a situational diagnostic to access the existing synergy between the two areas of Engineering previously mentioned and tends to transform the same into a learning organization to assimilate, integrate and consolidate the concepts, techniques and tools from Mining Engineering and Industrial Engineering.
