| Abstract | ROCHA, G. S. Proposta de Refinamento de Modelo de Controle Integrado da Produção e Qualidade com Uso de Dispositivos Móveis. 2015. Dissertação (Mestrado em Engenharia) – Programa de Pós-Graduação em Engenharia Civil, UFRGS, Porto Alegre. In many construction companies there are two separate production control systems in construction sites, one that is used to monitor the completion of activities, and another related to quality inspection. Previous studies pointed out that the separation between production control and quality control is a major cause of different categories of waste in construction sites, such as making-do, work in progress and rework, also contributing to the occurrence of informal tasks in project execution, i.e. activities that are not formally planned or controlled. Another consequence of this lack of integration is the lack of reliability of some production control measures, such as physical progress, and percentage of plans completed (PPC). The objective of this research work is to refine an integrated production and quality control model, proposed in previous studies, which includes the control of formal and informal tasks, and making-do waste, by using mobile computer devices. This model is linked to the Last Planner System of Production Control. Two empirical studies were carried out. In the first one some improvements were proposed in the existing model and a software tool was devised for the implementation of the model. In the second one the utility and applicability of the model was tested. The main contributions of this investigation for production control are related to the evaluation of prerequisites for starting each activity, the development of a simple way for monitoring informal tasks and making-do waste, and the flexibility for the inclusion of specific new work packages, which are needed for the Last Planner System.
