Resumo
Gestão significa manter um ciclo de acompanhamento contínuo sobre os sistemas produtivos, elegendo indicadores a serem comparados com padrões e metas, e atuando sobre as discrepâncias. Neste contexto, o desenvolvimento de tecnologias auxilia no monitoramento de operações e, combinados com ferramentas de controle de qualidade, podem auxiliar na detecção de falhas, no planejamento estratégico e nas tomadas de decisão. Desta forma, objetivou-se no presente trabalho aplicar ferramentas de qualidade na gestão da utilização de um grupo de tratores agrícolas que realizam operações de preparo de solo, visando estudar a variabilidade do processo em estudo, bem como selecionar ferramentas e qual seu melhor ajuste para sua aplicação. O trabalho foi desenvolvido a partir de dados gerenciais de uma empresa agrícola localizada no município de Matão – SP, onde foram estudados também ferramentas de apontamento, e as análises dos dados foram baseadas no controle estatístico de qualidade, sendo utilizadas as cartas de controle, com diversos modelos e diferentes níveis de rigor. Foram atribuídos indicadores gerenciais para os tratores avaliados, e as ferramentas de controle se mostraram aplicáveis à análise das operações, fornecendo parâmetros complementares aos indicadores já utilizados. Destas, as cartas de controle para valores individuais se destacaram no monitoramento da utilização dos tratores, na detecção de pontos de investigação e, consequentemente, na busca pela otimização do processo. Quanto aos tratores, se mostraram operacionalmente distintos entre si, havendo a presença de tratores utilizados com menor frequência e outros utilizados mais intensamente.
Management means maintaining continuous monitoring cycle of production systems, choosing indicators to be compared with standards and targets, and acting on the discrepancies. In this context, the development of technologies assists in monitoring operations and, combined with quality control tools, can assist in fault detection, strategic planning and decision making. Thus, it is aimed in this study apply quality tools in managing the use of a group of farm tractors that perform tillage operations, aiming to study the variability of the process under study, as well as select tools and what your best fit for your application. The study was conducted based on management data of an agricultural company located in the municipality of Matão - SP, which were also studied pointing tools, and data analysis was based on statistical quality control, and used the letters of control with several models and different levels of stringency. Management indicators for the evaluated tractors were allocated, and control tools have proven applicable to the analysis of operations, providing complementary parameters to the indicators already used. Of these, control charts for the individual values are highlighted in monitoring the use of tractors on detection research points and hence the search for process optimization. As regards tractors, they are shown operably distinct from each other, with the presence of tractor used less frequently and others used more intensively.
