Gestão da cadeia de suprimento e vantagem competitiva: uma análise em setores industriais a partir da visão relacional

This work has as its main purpose to investigate the contribution of supply chain management in order to obtain competitive advantage by companies from the textile industry and from Ceará footwear industry, focusing its analysis mainly in the interorganizational relations (dyadic). For this, the theoretical referential contemplates different explanatory streams of the competitive advantage, detaching the relational perception of the resources theory, as well as, the main presuppositions of the supply chain management which culminates with the development of an analysis sample that runs the empirical study; the one which considers an expanded purpose of the supply chain which includes the government and the abetment institutions as institutional environment representatives. Besides supply chain management consideration as a competitive advantage source, the work also tried to identify other possible competitive advantage sources for the companies of the investigated sectors. It represents a study of multiple interpretive cases, having four cases as a total; meaning two cases in each one of the sectors, which used as a primary data collecting instrument a semi-structured interview schedule. Different methods were used for the data analysis, the content analysis and the constant comparison methods, the analytical procedure originated from the grounded theory research strategy, which were applied the Atlas/ti software recourse. Considering the theoretical referential and the used analysis sample, four basic categories of the work were defined, including its respective proprieties and dimensions: (1) characteristics concerning to the relationship with the supplier; (2) the company relations with the government; (3) the company relations with the abetment institutions and; (4) obtaining sources of competitive advantage. In general, the applied research in the footwear sector revealed that in the relationships of the researched companies related to its suppliers, there is a predominance of the partnership system and the main presuppositions of the supply chain management are applied which contributes for the acquisition of the relational competitive advantage; while in the textile sector, only some of these presuppositions are applied, with little contribution for the relational competitive advantage. The main resource which was accessed by the companies in both sectors through its relationships with the government and the abetment institutions are the tax incentives which, for the footwear companies, contribute for the acquisition of the temporary competitive advantage in relation to the contestants who do not own productive installations in the Northeast region, it also conducts to a competitive parity situation in relation to the contestants who own productive installations in the Northeast region and to the external market contestants; while for the companies of the textile sector, the tax incentives run the companies to a competitive parity situation in relation to its contestants. Furthermore, the investigated companies from the two sectors possess acquisition sources of the competitive advantage which collimate with different explanatory streams (industrial analysis, resources theory, Austrian school and the dynamic capabilities theory), although there is a predominance of the product innovation as a competitive advantage source in both sectors, due to the bond of these with the fashion tendencies

Inserção de fornecedores locais como fonte de desempenhos em custos de transação e legitimidade: estudo de caso na cadeia produtiva do petróleo e gás do Rio Grande do Norte

The inclusion of local suppliers in production chains has considerable impact on its performance, but most notably in its main actors. The results of this process may be of different kinds and can be analyzed from economic or institutional approaches. This study aimed to verify the existence of different performances of Petrobras due to the inclusion of local suppliers in the oil and gas production chain in the state of Rio Grande do Norte, from the viewpoints of transaction costs and the Institutional Theory. In order to this, were made the characterization of the PROMINP, the description of its actions and results, the mapping of its institutional context of reference, and identification of results obtained by Petrobras in terms of transaction costs and legitimacy. The theoretical framework is based on authors dealing with industrial concentration, as like Marshall, Krugman, Porter and Schmitz, from the sociological perspective of neoinstitucional theory, as like DiMaggio and Powell and Scott and Meyer, and transaction costs, as like Williamson. This is a qualitative research, with data collection done by consulting secondary fonts and semi-structured interviews with nineteen actors of three groups, namely: actors involved in actions of the program, representatives of enterprises and representative of Petrobras. To analyze the content was used the Suchman s model (1995) for categories associated with strategies of legitimation and fourteen variables associated with the three variables assets specificity, bounded rationality and opportunism (Williamson, 1995, 1989) in the case of transaction costs. The results indicate that PROMINP has achieved its objectives by encouraging the increased participation of local companies in the oil and gas production chain, reflecting in the economic development of the state. The Redepetro/RN, fostered and built upon the interaction of the participants, is presented as a solution of continuity to the participation of enterprises in the chain, after the closure of the actions of the program. PROMINP demands responses to coercive, legislative and regulatory pressures of the organizational field, whose institutional context of reference is wide. From the point of view of legitimacy, through strategies to gain cognitive legitimacy and maintaining pragmatic legitimacy, Petrobras can manipulate the environment, ensuring the compliance of the constituents to their technical and institutional demands. Enterprises, in turn, respond to the demands through compliance with technical demands, mainly through the certification of processes, and cultural changes. There aren t clear gains related to the transaction costs, however, gains in legitimacy can be seen as a cumulative capital that can serve as a competitive differential that generates economic gains. In terms of theoretical findings, it was found that, due to its explanatory power for actions that are difficult to explain only in economic terms, Institutional Theory may be used as theoretical support concurrent with other theories. TCE model has limitations in explaining the program actions. In the case, it s emphasized that Petrobras doesn t seek only economic efficiency, but has in its mission the commitment to social development.

Gestão colegiada da cadeia produtiva da cajucultura: o papel do comitê gestor no Rio Grande do Norte à luz do desenvolvimento regional sustentável

The theme of this dissertation is the collegiate management in the cashew cultivation s productive chain by the reading of the Managerial Committee s role in accordance with Sustainable Regional Development. The research had as aim to reveal the way as Managerial Committee s members of cashew cultivation s productive chain interpret the economic, social and environmental dimensions to the sustainability of entrepreneurships, using as interpretative base Sachs (2004) theoretical model. The theoretical reference is based in precepts of Solidarity Economy as a strategy to the Sustainable Regional Development. To reach this aim was done a case study, based in analysis of contents and semi-structured interviews with the solidarities economic entrepreneurships that integrate the Committee and with the group of Entities of Support and Fomentation responsible for formulating and conducting actions in favour of development of the chain. The research permitted to conclude that the economic, mainly, and social dimension, secondly, to super-impose the environmental dimension. The actions in favour of the chain are yet restricted and with low effectiveness when interpreted, in an integrated way, by a side, by the informers of this research and, by another side, in accordance with precepts of sustainable development

Tecnologia social para autogestão : um estudo em empreendedorismo econômico solidário da cadeia produtiva da cajucultura no Rio Grande do Norte

The theme of this dissertation is social technology for self-management: a study in economic enterprise supportive of Rio Grande do Norte. The research aimed to obtain evidence that the reapplication of technology management, basic economic-financial and pricing, as production costs, has the potential to contribute to the self-management of APABV. The social technology and self-management are theoretical frameworks used and where workers are central figures in both the generation and replication of technologies that are compatible with their realities, as in the conduct and management approach adopted by them in their venture, they are makers decisions. To achieve the proposed objective was accomplished participatory research, which was used in addition to document analysis, participatory methodologies such as the construction of the DRP, group interview, experience in the production environment and family of entrepreneurs APABV. This research allowed the management technologies such as spreadsheets controls basic economic and financial costs, when socialized and understood by workers has the potential informational and become part of their daily decision-making process of the project, making up social technology

Tributos indiretos na cadeia produtiva do camarão

The state of Rio Grande do Norte counts with a relevant potential in the shrimp farming supply chain. In the larviculture step the state responds for more than half of the national production. In the farming step it is the second largest producer. In the industrial step, its industries have almost 40% of the shrimp processing capacity of the northeast of Brazil. However, this country has the highest tax rate comparing with the main shrimp producer countries. Considering the influence of taxes in the competition among companies, the main goal of this research is to analyze the impact of indirect taxes in the above steps of the supply chain. To achieve it, it will be used the data of the 2011 Census of the Shrimp Farming and it will be applied the Herfindahl-Hirschman Index to identify the market form of those steps. In order to contribute with the characterization of the supply chain, CEO´s of farms and industries will be interviewed. The price-elasticity of the shrimp larvae, the in natura shrimp and the processed shrimp will be analyzed in order to verify the possibility that each one of those three steps has to pass-through the onus of the end of benefit over the ICMS. The data analysis shows that the larviculture step functions as a duopoly and, facing the end of that benefit, it will be able to pass-through most its onus to the farming step. On the other hand, this step functions similar to a perfect competing market, which diminishes its capacity to pass-through that onus to the processing step. This step operates as oligopoly with a lower concentration than the larviculture step but, due to the fact that it faces an oligopsony, it will end up assuming most of that onus, which will cause a decrease in the amount of processed shrimp. It is concluded that the end of that benefit would impact negatively, in this state, the supply chain at all, but mainly the farming and the industrial steps

Análise da gestão da cadeia de suprimentos de um supermercado varejista através da utilização do modelo SCOR

In the last decade the complexity of the environment in which organizations are embedded increased dramatically, having on one side the increasingly demanding consumers in regard to the quality and value of the product and the other companies with the need to reduce operating costs in order to achieve greater profitability, without this there is a downturn in growth or market share powers. In this context the necessity of effectively structuring actions relating to the line with the operational work processes so that business objectives are achieved organizational strategic planning, ensuring the competitiveness of the organization. This study aims to analyze how you have made the management of the supply chain in a grocery retailer in the light of guidelines of Supply Chain Management by using the SCOR model. For realization of this study a survey was needed, classified according to their goals, exploratory and descriptive as to its procedure, document, field and case study. Thus, the processing of data will be qualitative merit, using the thematic categorical analysis of Bardin (1977). Thus, to obtain data interviews together the operational and strategic management of a company that was named Supermarket Omega were performed. After analyzing the information obtained is perceived that there is an effort of the organization enhance its management of the supply chain. However, there is a lack of alignment between the various areas that compose it. About their work processes, we stress that the focus of the company is still very directed on sailing than profitability, although it is undergoing a transformation in its organizational culture However, records the existence of many improvement projects in developing. Thus, it can be noticed that there is some consistency between the assumptions of the SCOR model and applied within the supply chain Omega Supermarket, although a greater effort to better align with the model still needs to be studied

Gestão da cadeia de suprimentos sustentável: entendendo o discurso brasileiro

Com o avanço nas pesquisas internacionais sobre sustentabilidade na cadeia de suprimentos, o objetivo aqui é analisar como está sendo veiculado o conceito de Gestão da Cadeia de Suprimentos Sustentável nos principais periódicos e congressos brasileiros ligados à área de Operações e Sustentabilidade na Administração. Reconhecendo o tema como incipiente, no Brasil ainda são poucos os estudos publicados, principalmente em periódicos. Os resultados indicam que o discurso sobre o tema pauta-se em discussões pontuais com enfoque recorrente à dimensão ambiental ou econômica, mas que não engloba a definição total do conceito, este fato mostra as possibilidades de avanço na temática.

A logística reversa e suas implicações na sustentabilidade: um estudo de caso de uma organização intermediária da cadeia reversa do ramo de sucatas

A sociedade impõe relações conscientes e saudáveis entre ela, consumidor, meio ambiente e economia de custo. Considerando os processos de retorno e descarte de resíduos, desenvolveram-se técnicas para que haja equilíbrio nas dimensões econômica, ambiental e social, sendo uma delas a logística reversa. Esse método minimiza as quantidades de resíduos descartados e promove seu reaproveitamento como fonte de matéria-prima em novos processos produtivos. No presente artigo, desenvolveu-se estudo de caso em uma recicladora que há doze anos coleta, classifica e separa materiais sólidos de indústrias do Distrito Industrial do Rio Grande (RS) para vendê-los a siderúrgicas e/ou comercializar subprodutos em condição de reuso no mercado local. Esse estudo tem por objetivo a análise das relações existentes entre as atividades logísticas reversas da recicladora em questão e as três dimensões da sustentabilidade. Tal análise justifica-se ao evidenciar como ocorre o processo de utilização da prática de logística reversa por uma organização intermediária, apontando-se sistematicamente as implicações ambientais, sociais e econômicas decorrentes de sua gestão.

Classificação como Conjunto de Interesse Público (CIP) dos Vestígios Arqueológicos de Lourosa

O presente projeto tem como principal objetivo a Classificação como Conjunto de Interesse Público (CIP) dos Vestígios Arqueológicos de Lourosa, associando ao estudo o potencial turístico que advém da ligação aos recursos patrimoniais. Outros objetivos: A Criação de um Centro Interpretativo da Cultura Judaica e o Reconhecimento e Notoriedade Internacional. O Turismo Cultural e Religioso, considerado como um produto emergente e inovador e uma das apostas do Plano Estratégico Nacional do Turismo (PENT) 2013/2015 continua a ser um recurso turístico do projeto Turismo 2020. A presença judaica em Portugal é tida pela comunidade científica como muito significativa e o seu valor patrimonial muito relevante. Constituem aspetos deste património histórico-cultural: as comunas e as judiarias, as sinagogas e os armários sagrados, as inscrições e as marcas de simbologia judaica e cristã-nova, as tradições e os costumes. A confluência entre a cultura, a religião e o turismo dá origem ao denominado Turismo Cultural e Religioso. A Organização Mundial do Turismo, identifica o turismo cultural como sendo: O movimento de pessoas essencialmente por motivos culturais, incluindo visitas de grupo, visitas culturais, viagens a festivais, visitas a sítios históricos e monumentos, folclore e peregrinação (OMT, 1985, citado por McKercher e du Cros, 2002). O turismo cultural tem sido considerado a área de maior crescimento no turismo global. O turismo religioso tem igualmente uma relação forte com o património existente sendo que, o principal objetivo é a participação em rituais de culto. Assim sendo, o turismo é uma atividade multifacetada que apresenta uma forte ligação com o património material e imaterial existente contribuindo desta forma, para o desenvolvimento económico e social de uma determinada região.

Estudo sobre a participação de roedores na cadeia de transmissão de Leishmania infantum (Protozoa: Trypanosomatidae) no Rio Grande do Norte

American visceral leishmaniasis is a zoonosis caused by Leishmania infantum and transmitted by the bite of the sand flies Lutzomia longipalpis.The main domestic reservoir is the dog, while foxes and opposums are the known wild reservoirs. However, identification of natural infections with L. infantum in rodents appears for need of investigating the participation of these rodents how source of infection of the parasite. In the present work the Leishmania infantum infection was investigated in rodents captured in Rio Grande do Norte, aiming at to offer subsidies to the understanding of the epidemic chains of LVA in the State. Thirteen Galea spixii were distributed in four groups, being G1 the group control with four animals and the others, G2, G3 and G4, with three animals each. Those animals were intraperitoneally inoculated with 107 promastigotas of L. infantum and accompanied for, respectively, 30, 90 and 180 days. Weekly the animals were monitored as for the corporal weight and rectal temperature. At the end of each stipulated period the animals were killed. Blood were used for determination of the parameters biochemical and haematological, PCR, ELISA, microscopic examination and cultivation in NNN medium. Liver, spleen and lymph node were used in Giemsa-stained impression and cultivation in NNN medium. Liver and spleen fragments were still used in PCR and histopathological, respectively. At the same time 79 rodents of the species Rattus rattus, Bolomys lasiurus, Oligoryzomys nigripis, Oryzomys subflavus and Trichomys apereoides were captured in the Municipal districts of Brejinho, Campo Grande, Coronel Ezequiel, Passa e Fica and Vázea for identification of natural infection with L. infantum. Evidence of infection was checked by direct examination of Giemsa-stained impression of liver, spleen and blood and culture of these tissues in NNN medium. Antibodies were researched by ELISA. They were not found differences among the weigh corporal final, rectal temperature and biochemical and haematological parameters of the Galea spixii controls and infected. The rectal temperature of the animals varied from 36OC to 40OC. For the first time values of the haematocrit (33,6% to 42,8%), hemoglobin (10,2 to 14,5g/dl), erythrocyts number (4,67x106 to 6,90x106/mm3), total leukocytes (0,9x103 to 9,2x103/mm3), platelets (49x103 to 509x103/mm3) total proteins (1,56 to 6,06 g/dl), albumin (1,34 to 3,05 g/dl) and globulins (0,20 to 3,01 g/dl) of the Galea spixii were determined. The lymphocytes were the most abundant leucocytes. Infection for L. infantum was diagnosed in two animals euthanasied 180 days after the infection. In one of the animals was also identified antibodies anti-Leishmania. The parasite was not found in none of the five other species of rodents captured. Galea spixii are resistant to the infection for L. infantum and they are not good models for the study for visceral leishmaniose, although they can act as infection sources. More studies are necessary to determine the paper of the rodents in the epidemic chain of transmission of the visceral leishmaniose in the State of Rio Grande do Norte

Gestão da cadeia de suprimento e vantagem competitiva: uma análise em setores industriais a partir da visão relacional

Considering the theoretical referential and the used analysis sample, four basic categories of the work were defined, including its respective proprieties and dimensions: (1) characteristics concerning to the relationship with the supplier; (2) the company relations with the government; (3) the company relations with the abetment institutions and; (4) obtaining sources of competitive advantage. In general, the applied research in the footwear sector revealed that in the relationships of the researched companies related to its suppliers, there is a predominance of the partnership system and the main presuppositions of the supply chain management are applied which contributes for the acquisition of the relational competitive advantage; while in the textile sector, only some of these presuppositions are applied, with little contribution for the relational competitive advantage. The main resource which was accessed by the companies in both sectors through its relationships with the government and the abetment institutions are the tax incentives which, for the footwear companies, contribute for the acquisition of the temporary competitive advantage in relation to the contestants who do not own productive installations in the Northeast region, it also conducts to a competitive parity situation in relation to the contestants who own productive installations in the Northeast region and to the external market contestants; while for the companies of the textile sector, the tax incentives run the companies to a competitive parity situation in relation to its contestants. Furthermore, the investigated companies from the two sectors possess acquisition sources of the competitive advantage which collimate with different explanatory streams (industrial analysis, resources theory, Austrian school and the dynamic capabilities theory), although there is a predominance of the product innovation as a competitive advantage source in both sectors, due to the bond of these with the fashion tendencies

Ferramentas de apoio à implementação da sustentabilidade na gestão da cadeia de abastecimento

O presente trabalho tem como principal objetivo contribuir para o desenvolvimento de um modelo de gestão da cadeia de abastecimento sustentável, posteriormente operacionalizado num conjunto de empresas. O principal elemento diferenciador do modelo apresentado é o seu cariz operacional, focado na fase da implementação com a integração de um conjunto de práticas de apoio à sustentabilidade. Para responder às pressões da conjuntura económica atual, das alterações climáticas, da escassez de recursos e das desigualdades sociais é necessário desenvolver de forma consolidada e abrangente um novo paradigma de gestão nas empresas. Muitas destas pressões fazem-se sentir nas atividades da Gestão da Cadeia de Abastecimento. O grande desafio é conseguir que as empresas obtenham bons resultados económicos, sociais e ambientais. A sustentabilidade tem sido abordada como a área de estudo donde deverá emergir este novo paradigma de gestão. Atendendo a esta problemática, a principal questão de investigação do presente trabalho é “Como se implementa a Sustentabilidade na Gestão da Cadeia de Abastecimento?” A metodologia de investigação partiu da revisão da literatura que permitiu estruturar um conjunto de pressupostos teóricos, estruturados num modelo conceptual sobre a implementação da sustentabilidade na Gestão da Cadeia de Abastecimento. O modelo foi aplicado em dois grupos de estudos empíricos: Análise Qualitativa de Relatórios de Sustentabilidade publicados por seis empresas com atividade em Portugal (Sonae; Lipor, Galp; EDP; Portucel e AutoEuropa); e o desenvolvimento de dois Estudos de Caso nas empresas Bosch Termotecnologia e Gestamp Aveiro. Os resultados permitiram o desenvolvimento de um Modelo Teórico de Implementação da Sustentabilidade na Gestão da Cadeia de Abastecimento. Bem como, um modelo de classificação das ferramentas de apoio à implementação da sustentabilidade adequadas a cada etapa que constitui o modelo de implementação. No desenvolvimento deste trabalho, acreditou-se que o caminho da sustentabilidade é possível e tangível. Os modelos desenvolvidos explicam que a integração da sustentabilidade se enceta pela estruturação da área da sustentabilidade na organização, prosseguindo com o processo de implementação constituído por quatro etapas: Envolvimento, Execução, Monitorização e Comunicação. A implementação necessita de ser abrangente a toda a cadeia de valor e apoiada num conjunto de ferramentas adequadas a cada fase de implementação.

Utilização de n-alcanos e álcoois de cadeia longa para estimar a ingestão e a digestibilidade em porcos alentejanos

O número diminuto de estudos sobre a técnica dos n-alcanos para porcos Alentejanos motivou o interesse em realizar um ensaio que simulasse as ingestões reais dos animais em Montanheira, no sentido de se compreender melhor o comportamento alimentar destes animais em condições extensivas. Para validar a técnica dos n-alcanos com altos níveis de ingestão em porcos Alentejanos, realizou-se um ensaio in vivo, em caixas metabólicas, com nove machos castrados da raça suína Alentejana com peso médio de 97,64 kg. O delineamento do ensaio experimental foi efectuado segundo o quadrado latino e os suínos foram alimentados três vezes por dia com bolota e luzerna desidratada foi também fornecido a cada animal diariamente, dois bolinhos contendo alcanos sintéticos (C32 e C36). No período experimental foram realizadas colheitas de fezes, refugos e alimento, para se estimar pelo método in vivo a digestibilidade e a ingestão. Calcularam-se as taxas de recuperação fecal para os n-alcanos e para os álcoois de cadeia longa, com o intuito de se identificar aqueles que apresentaram valores mais elevados e semelhantes entre si. O alcano que mostrou apresentar uma taxa de recuperação mais elevada e semelhante aos alcanos sintéticos foi o C29. Em relação aos álcoois de cadeia longa o que mostrou a taxa de recuperação fecal mais alta foi o C280H. Os n-alcanos naturais que melhor forneceram uma estimativa da digestibilidade foram o C25 e o C27. Na estimativa da ingestão os pares de alcanos que mais se aproximaram do valor real foram o C 29: C32 e o C29:C36· ABSTRACT; The miniature number of studies of the n-alkanes for Alentejano pigs motivated the interest in carrying 1hrough an essay that it simulated the real intake of the animal in "Montanheira”, the direction of to better understand the alimentary behavior of these animals in extensive conditions. To validate the technique of the n-alkanes with high levels of intake in Alentejano pigs, an in vivo essay was become fulfilled, in metabolic cages, with nine castred males of Alentejana swine race with average weight of97,64 kg. The delineation of the experimental essay was effected according to latin square and the swines had been fed 1hree times per day with acorn and deshydrated lucerne (Medicago sativa). Also it was supplied to each animal daily, two cookies contend synthetic alkanes (C32 e C36). ln experimental period had been carried through harvests of faeces, rubbishes and foods, to estimate digestibility and intake. The fecal recoveries for the n-alkanes and the long chain alcohols had been calculated, with the intention to identifying those that had presented higher and similar values. The alkane that showed to present a tax of higher and similar fecal recovery to synthetic alkanes was the C29. The long chain alcohol that it showed the higher fecal recovery was the C28OH. The natural alkanes that had better supplied an estimate of digestibility had been the C25 and C27. ln the estimate of intake the pairs of alkanes that been more come close to the real value had been the pair C29:C32 and the C29:C36.
