Atributos para seleção das tarefas da função manutenção: um enfoque intraorganizacional em aciarias

Resumo (EN)

This thesis aimed to identify the attributes and the Critical Success Factors for the selection of the maintenance function tasks in steel mills, and relate them to the system of production and operations, using the intra­organizational model. The sample population was composed of general managers and other managers of the production unit (steel mill) of the three steel mills studied. lnitially, it was identified the areas in which the steel mills are located, using secondary data. Afterwards organizational practices related to production and operations were identified through technical visits (participant observation), as well as the intra-organizational relationship between general manager of steel mill and the managements of the production unit (steel mill) were mapped and analyzed, with the utilization of UCINET 6.0 and Netdraw softwares. The exploratory, descriptive, with qualitative approach research used the multiple cases study in three integrated steel plants located in southeastern of Brazil and also used a methodological approach combining two different types of data collection techniques. These techniques were: bibliography, from the main indications in the literature in order to lead to the mapping of references on the categorized topics and subtopics, using the technique of Content Analysis; and the achievement of field work, through technical visits (participant observation) and the sending of questionnaires to the production unit managers (steel mill) of the three integrated steel plants used for studies. The choice of this methodological approach is justified by the nature of research questions (questionnaires). Among the achievement results, it was highlighted the methodological procedure for the selection of the maintenance function tasks in steel mills, the main purpose of this thesis; the construction of the theoretical apparatus that established the relationships between the bibliographical references; the field work in order to identify attributes and Critical Success Factors for the selection of the maintenance function tasks in steel mills; and the presentation of results and analysis of the contribution generated by the thesis, as the intra-organizational relationships through the coopetition and the main factors influencing the information sharing, the knowledge and the decision making within a production unit (steel mill). Finally, the identification of a set of attributes and Success Critical Factors for selecting the maintenance function's tasks was one of the structural requirements for completing the thesis. The results replicate the theory, showing that proactive maintenance policies when adopted add synergy to the production system. Designing such strategies indicates a competitive advantage with best practices in maintaining the function of the bias intra-organizational relationships.
