Desarrollo de un modelo de control de operaciones críticas de ajuste para mejorar la calidad en el ensamble de los vehículos en CIAUTO Ambato.

Abstract

The objective of this research was to develop a model of critical operation of setting control, to improve the quality in the assembly of CIAUTO vehicles from Ambato city. The main focus is on the adjustment process of the Assembly of a vehicle, from a large number of boards that has a unit. This document focuses on two main indicators, The Short-Term process capacity (St, Stc) and long Term (Lt, Ltc) process capacity, from these two indicators, the man indicator will be the Short-term process capacity. This indicator will show us the sigma quality level that the commercial has. As base for this indicator is suggested to start with a value of 1.33 as objective of level of quality sigma, this one will allow us to be positioned in level 4 of quality. For a better understanding of the methodology, it was structured according to the Deming or Plan cycle: plan – do – check – act (PDCA). In the plan part, it is considered everything that the CCA Auditor plans for his activities. The do part involves activities such as data, control charts, documents generation and control of it. Them, in the check part are all the indicator an finally is the Act part where is placed documented form each one of the improvements proposed. Whit the implementation of this methodology, an implemented system of 6% was possible to reach 74% of the implementation and this reflects an improvement of quality. It is important to highlight that the CCO system it in not a corrective tools by the contrary it is a preventive tool. The leadership has to ensure that the methodology be active, this can be obtained with a control crossed between the involved areas.
