Abstract:

Several points were stressed in our discussion on the performance given by Mr. Randall and Mr. Farmer. The most essential ones are stated hereafter. In order to put the discussion on a clear base it was first explained that here it is a question of a mere OR model whose objective function, which is to maximise, comprises a range of relevant variables. In the following we discussed the problem whether or not it would be useful to reduce to a linear function although the methodical knowing and the knowledge of the market-interrelations is sufficient to work with a non-linear function.
