Brazilian public hospitals face several operational problems not only related to poor public management practices and their complex nature, but also the economic, and social contexts. Considering this scenario and the fact that efforts in supply management might affect a hospital organization’s excellence, this research aims to identify improvements in the logistic operations at the surgical center satellite warehouse of a Public Hospital located in Brazil. A case study based on an exploratory and qualitative approach was conducted by employing document analysis, semi-structured interviews, and on-site observations. Seven major problems concerning lack of surgical material, the non-definition of crucial logistic parameters, low information flow, surgical supply control, and management problems were pointed and addressed by seven independent but complementary actions that considered the Brazilian healthcare system’s particularities. Given the nature of exploratory research, the results are not exhaustive and cannot be generalized to different contexts. However, they help understand that reducing the waste of the logistics processes makes it possible to improve the attention to the local population that uses public health services.

The metrology area is responsible for measurement properties and is present in the market through services related to calibration, standardization, maintenance, measurement traceability, and certification. While there is a demand from metrology companies for efficient methods of managing the quality of their services and operations, lean culture encompasses the most important management techniques with applications in various segments. Considering the aspects that permeate these two areas, the question arises about a possible intersection between the demands of companies and metrology laboratories to remain competitive and certified in the market and benefits provided by lean culture. Thus, this paper performs a systematic review, according to the PRISMA protocol, in order to verify if there is an intersection between lean and metrology in the scientific literature. Through bibliometric and qualitative analyses, the research shows a gap of application with a lack of articles in this area, as well as a great potential of places and tools to be implemented.

It is not obvious to adjust the speed of a conveyor belt so that it is possible to optimize the transport for each piece conveyed even with various studies presented in this area. The complex methodologies that are shown and the many adaptations indicated in these studies may contribute to the low adoption of these configurations. A study made, in this work, from videos of advertisements showing belt conveyor in operating on the factory floor which presented only 44% efficiency. In this work, it was shown, through theoretical studies, a mathematical model that presents the relationship between the speed and the transport capacity of conveyor belts. Based on a model, a graphical method (using templates) has been proposed that helps in choosing the conveyor belt speed for most efficient configurations that can be identified and adopted simply and without many adaptations to the system as a whole.
