Modelos causales para la implementación de herramientas de manufactura esbelta y cadena de suministro

Resum

Globalization has forced companies to modify their supply chains and techniques to ensure the quality in their products, since currently the production systems are geographically distributed. In the present thesis, two articles that investigate the critical success factors from the Six Sigma methodology as a tool for quality assurance in the maquiladora industry of Ciudad Juárez (Mexico) and its obtained benefits are reported. In addition, a third article addresses the effect of the flexibility and agility in the supply chain on its performance indexes, which is validated with data from the wine sector of La Rioja (Spain). Also, Structural equation models are generated to relate critical success factors from six sigma along with their benefits, as well as their flexibility and agility with their performance, also these relationships among variables portray a series of research hypotheses. In order to validate these hypotheses, data has been obtained from the maquiladora sector (Mexico) as well as from the wine industry of La Rioja. In addition, partial least squares techniques are used for evaluating the models. Finally, the results indicate that managers in maquiladora industries should focus their efforts on human resources training, such as, provide training to groups who are operating continuous improvement, as well as support an adequate knowledge management generated in projects, similarly, managers in wine sectors must make an effort to achieve flexibility in their distribution channels to generate agility in the products that are offered to customers.
