The use of the approach is illustrated via analysis of long-term development strategies for a national economy. The approach is based on the Feasible goals method. The method itself is quite universal and can be used for many purposes. When an economic system's performance indicators (objectives, criteria) are given, the GRS method provides a tool for multiobjective evaluation of the system's potentialities. In this paper, the GRS method helps to study a simple model describing transition from an "old" polluting technologies to a "modern" clean technologies while consumption, pollution and unemployment are taken into account.  Ключевые слова investment, economy, environment, multiple criteria programming
