Análisis de la metodología lean manufacturing para mejorar el proceso de faenamiento en el Camal Frigorífico Municipal de Ambato (CFMA)

Abstract

The activities that do not generate value, cause waste that may be present in the processes and that affect productivity, therefore, this research project focuses on the development of an analysis of the Lean Manufacturing methodology in the process of slaughtering pigs of the Camal Refrigerófico Municipal de Ambato (CFMA), since, the company does not have tools that allow it to diagnose, reduce or eliminate unproductive activities. The research has a quantitative approach, based on the calculation of numerical variables with the application of diagnostic, operational and monitoring tools of the Lean Manufacturing methodology. An initial diagnosis of the process was made, with the collection of information, using Industrial Engineering tools such as: process diagram and analytical course, describing activities, machines and inputs. A time study was developed to identify abnormalities of each process, by determining the number of samples by General Electric and timing of the activities with the back to zero method, to design a current VSM as a Lean Manufacturing diagnostic tool identifying: the activities, the times that add value and not to the process Waste was determined as: censing movements, incorrect waiting and processes, in addition, the potential causes of waste, to propose solutions with the operational tools, proposed as: 5S for the order and cleanliness of the areas, eliminating activities that do not add value to the process, and standardization to propose the reduction of incorrect processes based on work instructions and simulate them in the FlexSim 2019 program. It is concluded that the process has 30.35% of activities that do not add value to the process and affect productivity. Therefore, the process does not meet the company's specifications and improvement actions are required.
