RESUMO

This dissertation considers the performance of the companies that are responsible for water, electricity and natural gas networks named Utility Distribution Networks (UDN) as productive systems, in order to understand and evaluate the way that the efforts for continuous productivity improvement of their processes are conducted in search of goals such as more quality, less cost and less lead time to customer. The model that is used as a reference for this study is the lean production model, which was developed by the Toyota Motor Company in Japan, founded on the principle of search for productivity increase by the elimination on waste. Although it was originally disseminated in the auto industry value chain, the process improvement approach from this model has been considered in different industries. Therefore, the present work is motivated by the chance to explore the possibility of extending the lean production application concepts and practices to UDN companies. Firstly, UDNs value stream is analyzed, and two processes are chosen construction and maintenance for the development of study. Then, a bibliographic review is presented, from which a set of nineteen lean practices that maybe possibly applicable on the chosen processes is identified. By the development of three case studies, an evaluation is performed with the objective to analyze to what extent the companies that are responsible for UDN apply those lean practices on their processes, and to what extent the current application or a possible future application of each lean practice is motivated by lean thinking. Based on the data from the field research, the potential for effective application of the considered practices is evaluated for each process, taking into consideration the objective of elimination of waste. The study made it possible to verify that all the nineteen practices are applicable at least on one of the considered processes, and the majority is applicable on both processes.
