When we decide the optimum operative pattern, in the strict sence, we must consider every commitment of the generating units. However, these commitments tend to increase in geometric progression. In this paper, we create a level E (0≦E<1), and remove the unit which radio of unit cost to a maximum unit cost of generating is greater than E, and we will get another commitment of generating units. By using this method, we create the commitments of generating units, and we can avoid considering every commitment, and so can reduce of the memory requirement and computing time. Applying our method to the model system, we can see that the computing time is more reduced by increasing the value of E, and the solution is sliped out from the original optimum operative pattern, but this difference is very little.}, pages = {75--83}, title = {NO_Xの累積排出量が制約された場合の火力発電機群起動停止問題 (第3報)*}, volume = {11}, year = {1979} }
