MODELLING THE URBAN SUSTAINABLE DEVELOPMENT BY USING FUZZY SETS

The sustainable urban development is a subject of interest for regional policy makers and it needs appropriate assessment based on futile instruments for research, and for practical reasonsl (planning and decision making). Even if the sustainability’s attainment is a research topic field for academia and urban planners and managers and, as well, an ambitious goal for any resource administrator, yet there is no precise way of defining and measuring it. The sustainability of the urban development policy implies multiple and diversified aspects from rational exploitation of the local resources and well-structured workforce to environmental issues, endowment of modern urban facilities and infrastructure elements. As the urban sustainability is measured using a multitude of basic indicators, needing proper information to make long term management decision and planning, the subject is treated with fuzzy setsseen as an appropriate manner to deal with ambiguity, subjectivity and imprecision in the human reasoning when processing large volumes of data, eventually unstructured and complex. The paper proposed a modeling approach based on fuzzy sets inspired by the SAFE (Sustainability Assessment by Fuzzy Evaluation), a model which provides a mechanism for measuring development sustainability. The papers intends presenting a quantitative methodology in assessing the potential sustainability of urban development (in terms of adequacy) by pointing the failures in pursuing trends that are associated to a robust growth in the urban areas. The advantages of such approach are derived from taking into account the multi-criteria and uncertainty facets of the phenomenon; also, having in mind that the sustainability remains a non-straight-cut concept, being vaguely defined it implies a non-deterministic character by using the fuzzy set logic. The proposed model is designed to assess the divergence from desired trajectories, the weak point in reaching indicators’ target (as they are commonly regardedd as appropriate in what is understood as a good practices), it may then be addressed for policy makers in indicating some action measures in urban administration as they intendenly strive towards increasingly sustainable development on the long term.sustainability, urban management, indicators, fuzzy approach.

INTERDEPENDENCY BETWEEN SIMULATION MODEL DEVELOPMENT AND KNOWLEDGE MANAGEMENT

The paper discusses the relationship between simulation and knowledge management. Simulation models are increasingly being used to simulate processes in many different domains, including urban management, for solving decision problems. Usually, during the model development, the simulation team developing the model must rely on the knowledge provided by domain experts. In order to facilitate this simulation modelling process, appropriate collaborative knowledge management tools may be utilised. On the other hand, simulation models can facilitate knowledge management activities and processes as models could be used to evaluate decision alternatives before they are implemented or models could be used to simulate missing business data needed for discovering knowledge patterns. The paper concludes with a brief literature review of the some interdisciplinary applications that involve the combined use of both approaches. These applications include the use of system dynamics simulation for analysis of knowledge management strategies in organisational populations, learning curves, capital human modelling, and investigation of the influence of knowledge transfer and proximity (geographical, cognitive, and organizational) on the firm agglomeration process inside an industrial district.simulation modelling, knowledge management, system dynamics

The composite indicators used in assessing innovation at national level

The purpose of present paper is to present some recent developments in constructing composite innovation (or even, science and technology S&T) indicators on a national level. Measuring innovation at the national level is crucial in developing appropriate long term strategies for economic growth, because it is widely believed technological innovation is one of the main drivers of sustained economic-social welfare, if not the single most important driver of economic growth. Our purpose is to present a mapping exercise of metrics – based on composite indicators - found in the STI literature, pointing out those used in practice, with a view to corresponding values in the case of Romania. It has become standard practice to combine several indicators for science, technology, and innovation to form composite numbers. Composite indicators are increasingly being used to make cross-national comparisons of country performance in specified areas such as competitiveness, globalisation, innovation, etc.Innovation, innovation metrics, Science and Technology indicators, composite indicators, National Innovation Systems, Scoreboards.

POTENTIAL OF RURAL TOURISM IN ROMANIA

The tourism industry plays a more and more important role in the world economy, and is generally acknowledged to represent a significant source of economic growth for the European Union. In the present Romanian tourism losing the competitiveness face to demand of international market, moreover tourism contribution to the growth of the national economy is very low. This paper presents aspects of the rural tourism and analyses the Romanian tourism potential that holds a giant attractive heritage and Romanian rural tourism creates the conditions for preservation of structural and spiritual identity of the Romanian village. Modern human preferences are increasingly to rural tourism, because the villages are more accessible, more beautiful and original than many resorts suffer from smoothing
