MODERATING EFFECT OF SUPPLY CHAIN OPERATIONS STRATEGIES: THE MISSING LINK BETWEEN SUPPLY CHAIN RELATIONSHIP AND PERFORMANCE

Wang, Daisy Chen-yu 01 May 2011 (has links)
This is the first research to empirically study the congruity in supply chain operations strategies. The tests show that the congruity in supply chain operations strategies are related to performance and also moderate the association between performance and the types of supply chain relationships. 308 manufacturing firms were studied for empirical tests. Various methods including multiple regressions, cluster analyses, and logistic regressions are applied in this study. Based on the tests, five hypotheses are supported and only one hypothesis is inconclusive. This dissertation contributes in different thresholds. First, by studying operations strategies through a different angle (the supply chain instead of a firm) this study reconciles results in the relationships between performance and operations strategies and between performance and supply chain relationships. Therefore, this study contributes to reconciling two long-term puzzles in both operations strategies and supply chain management literatures. Second, this research draws on three different disciplines, operations strategies, supply chain management and organization theory (resource dependence theory). This interdisciplinary approach provides a broader perspective in operations management research. Third, through this research, guidelines are provided for not only powerful firms but also the weak ones on how to improve their performance through developing different types of supply chain relationships and integrating their operations strategies with their supply chain members.

Gonçalves, Juliana Machion 30 June 2014 (has links)
Made available in DSpace on 2016-06-02T19:50:24Z (GMT). No. of bitstreams: 1 6182.pdf: 3798401 bytes, checksum: 66577a762062dad65f82c270c5acd8cc (MD5) Previous issue date: 2014-06-30 / Financiadora de Estudos e Projetos / This research has, with main objective, the construction of activity ergonomics management model that is related operations strategies, developed from practical experience in the company with metal - mechanics production of white goods, involving a group of approximately 1.500 people and 400 workplaces, aimed at structuring an ergonomic action, based on the activity ergonomics, which it is aligned with the operations strategy and understanding the consequences (positive and negative) about ergonomics action, the perception of the operators and managers of the company, the relationship between health and work. The construction involved a participatory process the transformation of the working conditions and workplace conception. The theoretical-methodological approach has the assumptions of ergonomics work analysis and action research were used to construct the model based on the activity ergonomics of operations strategies related in order to emerge among all the actors involved greater understanding of the work, its determinants and constraints, as well as the instrument to represent the perceptions of the actors of this process and its contradictions. The demand started from high rates of removal by musculoskeletal disorders in the area of manufacturing company. The data were indicators that guided the certificates and clearances. Training, analysis / diagnosis and projects were the steps of action research. Relation about training, a ergonomics committee was formed with the performance of health professionals, process engineers and production supervisors. These actors were trained and helped to survey the descriptions of the task, the constraints involved, the rules and expected results and project items, so they would get to the point of view of activity and operations strategies, to further suggest recommendations necessary. Moreover, the process of analysis / diagnosis was developed from the ergonomics law (NR 17) with assumptions of ergonomic work analysis (AET). Finally, the stage was set designs from the results of a summary of the analysis / diagnosis. Every problem encountered was given a solution, aligning with operations strategies (organization of work, performance measures, process technologies, and human resources) through implementation of breaks, job rotation, procedure for development projects, order to modify the organization of work and technical and organizational design and in case devices, design of design processes and correction operations. From there, the team can count on financial support from the direction of the company and a specialized and skilled in analyzing work situations, innovative practices and active participation of the operator internal technical structure to generate credibility and consistency in actions that enhance and stimulate quality of work life. / Esta pesquisa tem como objetivo principal a construção de um modelo de gestão em ergonomia da atividade que esteja vinculado as estratégias de operações da empresa, desenvolvido a partir de uma experiência prática em uma empresa do setor mecânico de produção de produtos da linha branca, envolvendo um grupo de, aproximadamente, 1500 pessoas e 400 postos de trabalho, visando a estruturação de uma ação ergonômica, baseada na abordagem da ergonomia da atividade, que esteja alinhada com a estratégia de operações da empresa e a compreensão dos reflexos (positivos e negativos) da ação ergonômica, na percepção dos operadores e de gestores da empresa, na relação saúde e trabalho. A construção envolveu um processo participativo na transformação das condições de trabalho e de concepção dos postos de trabalho. Para caracterizar a abordagem teórico-metodológica, foram utilizados os pressupostos da análise ergonômica do trabalho e da pesquisa-ação, para estruturar e construir o modelo baseado na ergonomia da atividade vinculados as estratégias de operações, de forma a emergir junto aos atores envolvidos uma maior compreensão sobre o trabalho, seus condicionantes e determinantes, bem como o instrumento para representar as percepções dos atores desse processo e suas contradições. A demanda se iniciou a partir de altos índices de afastamento por problemas musculoesqueléticos na área de manufatura da empresa. Os indicadores que nortearam foram dados de atestados e afastamentos por CID M.65, M.75 e CID G56. Foram delimitadas as seguintes etapas da pesquisa-ação: capacitação, análise/diagnóstico e projetos. Em relação à capacitação, foi formado um comitê de ergonomia com a atuação de profissionais da saúde, engenheiros de processos e supervisores de produção, de forma que esses atores foram capacitados e contribuíram para o levantamento das descrições da tarefa, os constrangimentos envolvidos, as regras e resultados esperados e os itens de projetos, de modo que iriam chegar ao ponto de vista da atividade e estratégias de operações, para posteriormente sugerir recomendações necessárias. Além disso, o processo de análise/diagnóstico foi desenvolvido a partir do Manual da Norma Regulamentadora 17 (NR 17) com pressupostos da análise ergonômica do trabalho (AET). Por fim, a etapa de projetos foi definida a partir dos resultados de um resumo da análise/diagnóstico. A cada problema encontrado, foi dado uma solução, alinhando com estratégias de operações (organização do trabalho, medidas de desempenho, tecnologias de processo e recursos humanos) através de implementação de pausas, rodízio de postos de trabalho, procedimento para desenvolvimento de projetos, de forma a modificar a organização do trabalho e conceber dispositivos técnicos e organizacionais e no caso, o projeto dos processos de concepção e correção nas operações. A partir daí, a equipe pode contar com apoio financeiro da direção da empresa e de uma estrutura técnica interna especializada e capacitada em análise das situações de trabalho, práticas inovadoras e participação ativa do operador para gerar credibilidade e consistência nas ações que valorizem e estimulem a qualidade de vida no trabalho.
