Propuesta de implementación de justo a tiempo en el proceso de montaje hidráulico de cajas compactadoras para recolección de residuos sólidos

Abstract

Quality is a very important trend in companies today, since it allows guaranteeing the characteristics of each product, thus achieving customer satisfaction. The JIT methodology (just in time), indicates that in a continuous process the parts required for assembly are incorporated into it only when they are needed and in the necessary quantities (Ohno, 1993); that is why this work was carried out in an organization that has problems with downtime, increases in overtime and delays in delivering the finished product to the customer. For the implementation of this methodology the following stages were carried out: characterization of the hydraulic assembly process of the compactors for the collection of solid waste in order to diagnose the current situation, we continued with the recognition of the JIT philosophy and its application in the industry to understand its application structure, finally with the incorporation of the Just in Time methodology in the hydraulic Assembly process through the generation of an action plan. In the development, stages present in the hydraulic assembly process of garbage collection boxes were defined, the required materials and metal parts were determined and lean manufacturing tools were reviewed to define their applicability. The results obtained show a decrease in unemployment times, a reduction in overtime and an increase in delivery compliance. Based on the diagnosis obtained in the study company, it was possible to identify processes such as (storage, hydraulic assemblies, subassembly of parts) in which the methodology could be implemented, focusing actions in order to meet the objectives
