Iterative methodology is given in five steps: (1) linearization the set of nonlinear constraints at particular point, (2) solving the problem of normalized linear goal programming, (3) feasible direction computation, (4) calculating optimal step length displacement, and (5) testing out convergence problem. Our idea was to apply Euler’s theorem for the “total” linearization of the nonlinear constraints (in the space) around particular point. According to Euler’s theorem, it is possible to apply this methodology to solve the problems of NGP whether the nonlinear constraint functions are linearly or positively homogeneous.

Pod odlučivanjem podrazumijevamo postupak izbora jedne od mogućih varijanti (alternativa) odluke. Glavni elementi problema odlučivanja su ciljevi koji se žele postići odlukom, alternative između kojih se vrši izbor (bira) i kriteriji koji se koriste kod izbora. Odlučivanje, odnosno izbor između dvije ili više alternativa moguće je napraviti na različite načine, koristeći: tehnike odlučivanja, pravila odlučivanja i vještine odlučivanja. Četiri osnovne tehnike u tretiranju problema odlučivanja u ekonomiji i menadžmentu su optimalizacija, simulacija, metode pretraživanja i teorija igara. U radu se veoma sažeto opisuju osnovni pojmovi koji se koriste u svakoj od navedenih tehnika i alata, kao i karakteristike situacija u kojima se one najefi kasnije koriste. Zatim, na praktičnom primjeru demonstriraju se određeni aspekti teorije igara kao analitičkog alata koji se koristi u procesu strateškog odlučivanja. Na kraju rada sagledava se značaj i mogućnost primjene teorije igara u analizi složenih ekonomskih problema, prije svega ravnoteže na oligopolskom tržištu.

Bosnia and Herzegovina have significant physical potential regarding to renewable energy sources.... more Bosnia and Herzegovina have significant physical potential regarding to renewable energy sources. Hydro, biomass, geothermal, wind, and solar potential can play important role in the whole state economy. Bosnia and Herzegovina is Non-Annex I country according to UNFCCC and according to that it is obligated to participate in the global efforts in order to reduce green house gases emission. This paper gives some analysis of the physical, technological, economic, and market potential of renewable energy sources in Bosnia and Herzegovina and their potential role in mitigation of climate changes. Paper also gives the analysis of the potential connections between renewable energy sources and sustainable development of the economy, taking in to consideration specific political structure of the state. Bosnia and Herzegovina is consisting from two entities: Republic of Srpska and Federation of Bosnia and Herzegovina, and Brcko District; energy sector and climate changes mitigation measures a...

We cannot forecast economic events with a very high scientific precision. It is very clear that there does not exist a unique "general" model, which can yield all answers to a wide range of macroeconomic issues. Therefore, we use several different kinds of models on segments of the macroeconomic problem. Different models can distinguish/solve economy desegregation, time series analysis and other subfactors involved in macroeconomic problem solving. A major issue becomes finding a meaningful method to link these econometric models.
