This paper describes a new methodology adopted for urban traffic stream optimization. By using Petri net analysis as fitness function of a Genetic Algorithm, an entire urban road network is controlled in real time. With the advent of new technologies that have been published, particularly focusing on communications among vehicles and roads infrastructures, we consider that vehicles can provide their positions and their destinations to a central server so that it is able to calculate the best route for one of them. Our tests concentrate on comparisons between the proposed approach and other algorithms that are currently used for the same purpose, being possible to conclude that our algorithm optimizes traffic in a relevant manner.

Across the industry, regardless of the activity which is intended, the electricity distribution must meet the current and ever growing needs of the market, aiming at reliability and process efficiency. The energy must not only be available to ensure continuity of operation, but also to avoid the costs incurred due to deficiencies and failures. The tendency to migrate to intelligent systems is undeniable and this thesis will be analyzed the advantages that made this kind technology essential, focused on the analysis of the motor control center and as sturdy equipment fit to the concept of intelligent panels. The case study compares in a real scenario the acquisition of a system of low-voltage electrical panels comparing the cost to purchase the same set of panels made with and without the concept of intelligence

This work aims to express the production and consumption changes occurred in the State of São Paulo in line with the logistics, the systems of movement and the economic flows. The mentioned productive and consumption devolutions towards the interior just was possible in the fast rhythm, with the hierarchical combination of some basic elements, such as: 1) the logistics as strategy, planning and management (including in the concession of public services to the private enterprise) of transports, storage and communications; 2) the technological improvement of systems of movement (infrastructure and means of transportation) and 3) the economic flows (goods, services, informations, capital gains and people) in the territory. Thus, we go to an analysis of the impacts of the fifth logistics revolution and the alternatives between systems of movement and territorial fluidity in the service of corporative demands in the space pertaining to the State of São Paulo. © Copyright Scripta Nova, 2009.
