标题：Settlement of the Pollutant Economic Agents Monitored Interval in the Romanian Southeast Region using Multi-criteria Shaping Through the Expert System DEXi
摘要：Romania has been turning in the last 20 years towards the development of the private sector. Micro-enterprises, small and medium enterprises were born in all national economy branches. Many of them were created through the partition of the large enterprises developed before 1989. The Romanian South-East region comprises six counties that cover 35.762 km2 (15% from the entire surface of the country) placing second for its size from a number of eight that Romania has. The area has a population of approximately 2.850.318 residents, representing about 13% from the country's population. The urban counts 55.5% from the population, with a tendency to diminution. The largest city in the area is represented by Constanta (309.965), followed by Galati and Braila (over 200.000 residents). The economy of the counties was mostly developed thanks to the natural resources they possess (oil, natural gases, limestone) and to the facilities created by nature (the Black Sea, the Danube, the Danube Delta, fields, hilly areas). At present, in the south-east area there are round about 6.517 industrial enterprises working (during 2010), from which 101 large industrial enterprises (1.54%).It's a known fact that the production of the large polluting enterprises in industry is permanently monitored by the Environment Protection Agencies. A lot of them were "forced" to make investments in the environment protection field, but especially respect the rules imposed by the European Union legislation. It is not the same thing happening to micro-enterprises, small and medium enterprises, where their production depends on a series of documents filled on their own account (for example: environment notice).The method we propose is that of multi-criteria modelling. To create and apply the qualitative decision pattern in order to establish the pollutant economic agents monitoring interval, expert system DEXi was used. In this work, our researches were based upon data gathered from the natural resources (oil, natural gases) extraction and processing from the south-east region. Following researches will also have in view other economic branches in the region, continuing to create in the end a monitoring interval settlement of multi-criteria pattern, which comprises as many branches as possible
