Projeto conceitual de um sistema de acompanhamento e controle de operações baseado na manufatura enxuta

Abstract

The present study addressed the planning and development of a system for monitoring and control of production operations, this proposal represents one of the major output from the execution of a technological innovative project sponsored by the National Council for Scientific and Technological Development (CNPq) – the Program for Human Resources Training in Strategic Areas (RHAE), the program included creating a partnership between a university and a company to carry out the research activities. The use of lean manufacturing concepts, such as Jidoka (fail-safe mechanisms and automation with a human touch), through the use of mistake-proofing devices (poka-yoke) and heijunka (production leveling) oriented the development of the system and its working principle is based on the Andon (visual management system that assists in failure identification in the production system). The system is intended to enable real-time monitoring of industrial processes, transmitting crucial information for decision making process regarding the presence of anomalies that negatively impact the production process, such as defects propagations, interruption of production flow, lack of supply, incorrect configuration of machinery and equipment. Thus, streamlining the realization of corrective and preventive actions to restore the normal production flow regime. The main benefit of implementing this system, however, is related to the paradigm shift that it causes in the organization, by modifying the current organizational culture to one more focused on innovation, the elimination of defects and to the continuous improvement of products and processes (Kaizen). Hence, the introduction of these concepts, facilitated by the use of the proposed system, can enable small and medium-sized industries to achieve high efficiency levels and allow them to implement strategies performed by market-leading companies.
