Redução de custos com um sistema de gestão de qualidade: estudo de caso na montagem de pré-fabricados

Abstract

For a company to become competitive and efficient, the constant search for quality and optimization in its production avoiding errors and rework in products and consequently unforeseen costs. The research was delimited in the case study of the assembly of prefabricated concrete parts in four works, with the main objective of pointing out the percentage variation of the increase in the final cost, identifying the most recurrent nonconformities in the products and their main causes and proposing improvements in the processes. At the end of this study, we obtained the percentage values of increases in the final costs of the assemblies of the prefabricated structures in the works. In work 1 we had an increase of 6.18% in the final cost for the assembly of the prefabricated structure, in work 2 this increase was 7.25% in the cost for this assembly, in work 3 there was an increase of 5.5% in this cost and in work 4 the increase was 9.67% in relation to the initial cost budgeted for the assembly of this structure and that the main cause of these failures is an inefficient quality management in the process productive parts in the factory.
