Abstract
La presente memoria tiene por objetivo disminuir las pérdidas producidas por concepto dedesperdicio de material en una fábrica de neumáticos empleando para ello la metodología DMAIC.Se comienza con el desarrollo del marco teórico como fundamento de la metodología. Posteriora ello se describe el proceso productivo en la fabricación de neumáticos. A continuación sedesarrollan las etapas de definir, medir, analizar, mejorar y controlar del proceso en estudio.En la etapa definir se identifica el problema en el proceso de requerimiento de materiales, elcual recae en que se produce más material del requerido realmente y debido al vencimiento de losmateriales, estos deben ser eliminados. Junto con ello se identificaron los factores críticos de esteproblema con el propósito de enfocar los recursos de manera más eficiente.En la etapa medir se describe el método empleado en la toma de datos, se selecciona el tipo deanálisis a realizar y se utilizan gráficas de control para interpretar los datos obtenidos. También seconstruyen gráficas de Pareto con el fin de identificar posibles causas que expliquen el origen delproblema.Continuando con la etapa analizar, se trabaja en conjunto con todos los integrantes que conformaneste proyecto más múltiples colaboradores de planta que pueden aportar con una visióninterna y experimentada. Se construye un diagrama de Ishikawa que permite identificar diversosfactores que contribuyen a la problemática en cuestión.En la etapa mejorar se realizan varias propuestas de mejora para cada una de las problemáticasdetectadas en la fase anterior. Junto con ello se jerarquizan de manera de optimizar los recursos,dándole prioridad a las mejoras que tengan un mayor impacto utilizando un menor esfuerzo.También se designó para cada mejora un responsable y plazos específicos para implementar lasiniciativas.En la etapa controlar se propone el uso de gráficas de control y la utilización de una planillade seguimiento, la que permite detectar y mantener información actualizada de operadores queproduzcan exceso de material.Finalmente se realiza una evaluación de impacto económico y operacional sobre las propuestasrealizadas, las cuales se proyectan para el año 2017 en tres escenarios posibles: optimista, neutroy pesimista, obteniendo como resultado la viabilidad del proyecto en todos los casos, sin embargose pretenden alcanzar los resultados obtenidos en un escenario mixto entre optimista y neutro.
The obtective of this statement is to try demostrate how is possible to reduce loss of materialin a tire factory. For this proyect, it was used DMAIC methodology.First, the theroretical framework is implemented as a foundation of methodology. After this,the production process described in the manufacture of tires. Then, the stage are carry out: define,measure,analyze,improve and control.In step define, the prblem is identified in the process material requeriments, wich is requestmore material than is really needed. For that reason, the materials are due and must be eliminated.Along with this the critical factors of this problem in order to focus resources more ecientlyidentified.In step measuring method used is described in data collection , the type of analysis to beperformed is selected and control charts are used to interpret the data.They are also built withPareto charts to identify possible causes to explain the origin of the problem.Continuing the analysis stage , working together with all members that make this project moremultiple partners plant that can provide an internal vision and experienced.Ishikawa diagram thatidentifies various factors that contribute to the problem in question is constructed.In step improve various improvement proposals are made for each of the problems detectedin the previous phase. Along with this are prioritized in order to optimize resources , giving priorityto the improvements that have greater impact using less eort. He also appointed for eachimprovement responsible and specific deadlines to implement the initiatives .In step control the use of control charts and the use of a tracking form is proposed , which candetect and update of information operators that produce excess material.Finally an assessment of economic and operational impact on the proposals , which are projectedfor 2017 in three scenarios is performed: optimistic , neutral and pessimistic , resulting inthe project’s viability in all cases , however are intended achieve the results in a mixed scenariobetween optimistic and neutral.
