Estudio de tiempos y movimientos de los procesos de mantenimiento de las casetas en el taller de guías y montajes de los trenes 1 y 2 de la empresa Novacero S.A. planta Lasso

Abstract

The following research project deals with the study of times and movements in the maintenance processes of the rolling stands in the guide and assembly workshop of production trains 1 and 2 of the company NOVACERO S.A. Lasso plant in order to standardize processes, reduce times and movements, in addition to seeking improvement situations in maintenance activities; the problem lies in the fact that the maintenance processes are not completely documented and in the non-existence of records of the execution times of the activities. This makes it difficult to plan maintenance stops for production trains, as well as reducing the chances of discovering opportunities for improvement in the work method, transfers or plant layout. Through a study of times and movements, using the Westinghouse system for the assessment of the pace of work and the allocation of supplements according to the International Labor Organization (ILO), a plant distribution is proposed for the workshop of guides and assemblies through the SLP method through which to optimize times and distances in the execution of the maintenance processes of rolling stands. The result was a 2.62% reduction in the execution time of the maintenance process and a 65.56% reduction in the total distance traveled within the workshop. Changed the distribution type from a fixed and process layout in the current distribution to a line process layout in the proposed distribution. In addition, a manual of processes and procedures aimed at standardizing the maintenance processes of rolling booths was generated with the purpose of guiding the operators in the execution of maintenance tasks.
