Resumo
O presente artigo aborda a questão da baixa utilização de modelos analíticos nos processos de decisão em planejamento da produção e estoques nas empresas. Para identificar as possíveis razões deste fato, foi realizado um estudo de caso em empresas da Indústria Farmacêutica Brasileira, por meio de visitas e entrevistas com os responsáveis pelo planejamento da produção. As empresas consideradas são multinacionais de grande porte, localizadas na região metropolitana de São Paulo. A partir dos resultados das pesquisas de campo e bibliográfica, verificou-se que a complexidade matemática e a falta de experiência dos profissionais com o desenvolvimento e implantação de modelos analíticos são os principais fatores que explicam a baixa utilização destes modelos nas empresas. Finalmente, os autores propõem algumas ações referentes a: i) formação profissional; ii) parcerias com empresas de tecnologia de informação; iii) pesquisa acadêmica na área de planejamento da produção e estoques.
Palavras-chave
Pesquisa operacional, planejamento e controle da produção, MRP, teoria e prática
Abstract
In this paper the reader will find a descriptive research, which aims to identify the reasons why people don't use operations research models in the production and inventory management. A case study is conducted in the Brazilian Pharmaceutical Industry by means of personal interviews with the operations managers of some sampled multinational companies. The results of the field research and the literature review show that both the complexity and the lack of experience with the operations research approach prevent the development and use of decision support systems based on more sophisticated models. Finally, in order to bridge the gap between theory and practice in the production and inventory management field, the authors suggest several actions in the following key areas: i) the professional education; ii) the partnership between academics and the IT companies; iii) the academic research in the field of production and inventory management.
