Mejoramiento del sistema productivo mediante la aplicación de la metodología lean Manufacturing en la producción de cal de MINABRADEC Compañía Limitada de la ciudad de Riobamba.

Abstract

The objective was to improve the productive system through the application of the lean manufacturing methodology in the production of lime from “Minabradec Compañía Limitada” in the city of Riobamba, which allowed reducing production times based on the elimination of processes that do not generate added value to the product. ; The information gathering was carried out by measuring times with stopwatches, process diagrams, process analysis diagrams, and journey diagrams and applying the 5S' and Value Stream Mapping (VSM) tools, achieving optimal results by implementing a continuous improvement plan. The development of the lean manufacturing methodology was contemplated in the first instance the initial assessment of the company through the VSM tool through the process analysis diagram, through an on-site inspection of the company, finding a productivity of 2,278 bags/ hour, later the non-compliance with the application of the methodology was identified as the main problem, determining a 22.6% compliance with the 5S' parameters, corresponding to an unsatisfactory percentage of performance, then the process improvement methodology was implemented through the standardization of processes, obtaining as a result 78% compliance, generating good performance, improving the culture of cleanliness and organization in the workplace and reducing the waste of material thanks to compliance with the parameters considered in the 5S' methodology, finally the methodology through a socialization of the proposal to the company personnel, in which the distribution of the plant was optimized, going from 184 m in the route diagram in the initial situation to 34 m in the proposal presented, improving productivity in 0.30 sacks/hour, that is, 4.20 sacks were increased in the production of the working day, validating the alternative hypothesis in which productivity in the organization is improved.
