Propuesta de un sistema de producción para la empresa “OMEGA” ubicada en la ciudad de Riobamba en base a las herramientas del Lean Manufacturing.

Abstract

“OMEGA” Enterprise is located in Chimborazo province, Riobamba canton; which is dedicated to the manufacture of stainless steel machinery such as storage tanks, pasteurizers, yogurt maker, among others. Currently, its production system limits its productivity as well as its competitiveness in the market, limiting companies’ growth. For this reason, this research work proposes a production system based on Lean Manufacturing tools. The analysis and evaluation of the production system by means of quality tools and method engineering determined that the company has overproduction problems, delays, lack of organization in work places and the need to make a plant reengineering. In order to solve all the mentioned problems, the following tools were used: a value stream map, 5S, Just in time (JIT), SMED (Single-Minute Exchange of Die), Poka Joke and Kaizen; by means of these tools, a plant distribution is proposed which improves working conditions, maintain a unidirectional flow of production and in general improve the working method with the aim of reducing the labor cost. The production system is standardized through procedures and recommendations given by each mentioned tools. In addition, the investment of the proposed production system is justified through the indicators NPV (Net Present Value), IRR (Internal Rate of Return) and PPI (Payback Period of Investment). In general, the proposed production system improves notably its productivity, production capacity, decreases delay times and overproduction; giving the opportunity for the company to grow by attracting new markets.
