Many times, however, this subject has been put aside due to other priorities, mainly the ones associated with public transportation and with people movement in general. This can be confirmed when one compares the number of scientific publications dealing with such themes. But, due to the growing volumes of urban cargo, mainly in the CBDs, the subject “urban cargo” is receiving much more attention recently, particularly when proposing measures to improve environmental conditions in these centers. Thus, with the objective of keeping urban mobility within a sustainable transportation framework, new propositions are being developed concerning new forms of delivering merchandises in the city, as a way to mitigate the negative effects of such activities (which involve nuisance of different kinds: visual, sound, pollutant emissions etc). Five key areas can be identified as possible transportation strategies, from which it is possible to extract environmental gains and increasing competitiveness for the enterprises involved in the process of displacing cargo: 1) less polluting engines, 2) personal training (truck drivers), 3) choice of more favorable transportation modes, 4) reduction of the number of vehicles in the traffic network, and 5) the adoption of city logistics concepts. In this thesis we analyze the benefits generated by the use of city logistics concepts directed to the improvement of the urban environment with a national focus. The CBD of Florianópolis-SC, Brazil, was considered in the application. The corresponding costs were estimated (man power, operations, facilities) for the actual reality. Then, these elements were compared with another alternative formulation, hypothetical, where the concepts of city logistics were predominant. Good results, either under the environmental point of view (reduction of pollution levels and of moving vehicles), or under the competitive framework (cost reduction), were observed, which endorse and stimulate the adoption of this novel concept.

The Master Production Schedule (MPS) - to the lean manufacturing - needs to be leveled with the demand (heijunka), so that clients’ needs are met, without keeping the stocks high, which according to lean approach mean a loss by overproduction. In addition, the productive system needs to meet the client’s demands without overload or idleness of the productive resources. In line with that, this thesis proposes a model to diagnose the MPS, from indexes of practices adopted and the performances obtained by the organizations, in order to relate the results from those indexes to the stage of production leveling. The literature review has identified the state of the art related to the subject of this thesis, besides substantiating its newness and relevance. It is presented the proposed method - MPSBM (Master Production Schedule Benchmarking) - which enables the diagnosis of the way how the organizations operate their master production schedule, in order to obtain the leveling, besides identifying which actions might be taken, so that the heijunka happens. It aims, in this way, to highlight the relation between the MPS leveling and the lean manufacturing stage in which the productive system encounters itself, since that relation has been depicted in the theoretical discussions present in literature, without, however, owning an instrument that allows the evaluation of that relation. In order to make possible the discussion of the relations between the leveled MPS and the lean manufacturing, it has been also applied the Lean Benchmarking diagnosis (BME), which has been developed by the Laboratório de Simulação de Sistemas de Produção (LSSP), from Universidade Federal de Santa Catarina. This simultaneous analysis is based on the observation that the production leveling influences on obtaining the lean manufacturing. It is a qualitative research of exploratory and descriptive nature. To test the proposed model, it has been used in six companies, and in one of them it has been applied in three different processes, which results in eight applications. The results of the applications have provided the identification of strengths and opportunities for improvement in the production management and have enabled verifying the relationship between the leveled MPS and the stage in which the companies encounter themselves in terms of lean manufacturing, making it, in this way, an element which deserves the attention of organizations which aim a lean manufacturing.
