Evaluación de la capacidad de trabajo y estandarización de los tiempos en las pruebas de ensayo de compresión en punteras de seguridad en el laboratorio de análisis de esfuerzos y vibraciones (LAEV)

Abstract

The first chapter of this research is focused on the theoretical aspect of safety toe caps, their use, the types of toe caps that exist in the market, and the applicable mechanical tests. A brief reference is made to the LAEV laboratory, the tests carried out there, and the regulations used. Engineering method, times and their main tools are also described. The second chapter describes the research design, the methodology to be used to determine the sampling and the work times. In addition, a specific description of the types of research and its application in the present investigation is made. It also includes the definition of the 5 S and Kanban methodologies that will be used as tools for continuous improvement. For the third chapter, an explanation of the conformation of the laboratory is made, through the use of technical tools the main processes and the probable problems that may arise in the tests are described. With the application it the time’s study is possible to establish the standard time, the stop times, the real capacity of the laboratory, the performance and availability as indicators of productivity. In addition, an in order análisis state and cleanliness in the workplace is carried out. In the last chapter the proposed implementation to solve the problems detected is analyzed. With the application of the methodologies and tools described above, the analysis of times is carried out again and the flow chart of operations is also included. Obtaining positive results in the proposed indicators and showing a clear reduction in test times, verifying the initial hypothesis. Finally, the viability of this proposal is evidenced by means of the VAN and TIR indicators of the economic analysis.
