In this context the use of water for the production of hydro-energy is essential. Actually the energetic system of Kosova is based on thermo-energy, so the use of water resources for the production of hydro energy will increase further the energy production of the country. On the other hand, a master plan of multiple use of water resources, based on the principle of integrated and sustainable management, will insure better services for other users of the country. There are four basins in Kosovo： basin of the Drini i Bardhe River, basin of Ibar River, basin of Morava e Bing^s and Lepenci Rivers. The watershed of Bistrica e Pejes belongs to the basin of Drini i Bardhe, which belongs to the Adriatic Sea catchment. It has an admirable capacity therefore should be treated as a complex capacity, in which important economic components of water can be introduced such as： drinking water supply, water for irrigation in both sides of valley, fish economy and recreation, hydro-energy etc..展开更多

Weight is the type of function that changes with forecast time. A relatively rational description of the system can be proposed with the forecasting method, which is of higher precision and better stability. Two individual forecasting models, grey system forecasting and multiple regression forecasting, were generated based on the historical data and influencing factors of coal demand in China from 1981 to 2008. According to the theory of combination forecasting, the variable weight combination forecasting model was formulated to forecast coal demand in China for the next 12 years.展开更多
