Many approaches to the problem of competitiveness show that, today, competitiveness is defined by the economic factors and indicators and is more a suggested/induced notion than a numerically evaluated one. The approaches are of economic and managerial nature, while the relationship with the technical aspects of competitiveness is less noticeable. At this point there is no algorithm to evaluate the technical and economic competitiveness, moreover, the technical factors are not considered, although consumption and costs incurred by the manufacturing processes are generated by technical actions. In this context, the notion of competitiveness gains new valences, including factors and policies that determine the ability of the enterprise to get a favourable place on the market, to maintain that place and to continuously improve its position. In this paper, competitiveness will be understood as the capacity (potential) to provide performance (compared with other similar elements), in a very punctual way, within a macroeconomic concrete context and at a certain time. A case study referring to the assessment algorithm is presented, showing the use of the algorithm in the on-line management of the manufacturing system to obtain maximum competitiveness.

Dynamic characteristics for transitory state working regime were deduced and possible pressure resonances induced into the base system by the pump flow variation were defined The Annals of ''Dunarea de Jos'' University of Galati Fascicle XIV MECHANICAL ENGINEERING, ISSN 1224 - 5615 Sat, 01 Jan 2011 00:00:00 GMT http://arthra.ugal.ro/handle/20.500.14043/24740 2011-01-01T00:00:00Z http://arthra.ugal.ro/handle/20.500.14043/24739 Solution for Energy consumption Uniformity at Single Bucket Excavators Axinti, Gabriel; Axinti, Adrian-Sorin This paper presents a possible technical solution for energy consumption uniformity at single bucket excavators. The basics of this proposed solution consist of energy inertially stocked up and the proper way to implement this idea into the hydraulic driving system of the equipment. This kind of system was defined as a retrieval system because of the distinctive character comparative to other driving systems as follows: Load Sensing, adaptive, classical systems, etc. The Annals of ''Dunarea de Jos'' University of Galati Fascicle XIV MECHANICAL ENGINEERING, ISSN 1224 - 5615 Sat, 01 Jan 2011 00:00:00 GMT http://arthra.ugal.ro/handle/20.500.14043/24739 2011-01-01T00:00:00Z http://arthra.ugal.ro/handle/20.500.14043/24738 The Impulsive Loading Influence on Dynamic Response Parameters of the Viaduct Type Structure Leopa, Adrian Bridges and viaducts are vital structures ensuring ways of communication, so they must be protected from dynamic loads from traffic or seismic activity. For this reason are embedded in their structure dynamic isolation systems for damping and isolating the shocks and vibration to which they are subjected. For a correct choice, from the dynamic point of view of viscoelastic type systems and to estimate their optimal lifetime is required thorough knowledge of the dynamic loads to which they are subjected. In this paper will be analyzed from the experimental point of view, the disturbing signals stemming a heavy vehicle from passing at different speeds over an obstacle positioned transversely to the travel position.
