It is shown that the proposal for a utility-weighted informational measure discussed by Belis, and Guiasu (Belis, M., S. Guiasu. 1968. A quantitative-qualitative measure of information in cybernetic systems. IEEE Trans. Information Theory 14 593--594.) and others can be formulated in terms of...

The impact of price changes in geometric programming is analyzed in terms of technological substitution relationships. The method can also be applied to sensitivity analysis, which is illustrated by means of a numerical example.

Balance sheets and income statements are numerical decompositions of certain total sums: total assets, total liabilities, total sales, and total costs and expenses. The behavior of individual items measured as fractions of the corresponding total is important for the analysis of the company's...

Von Neumann and Morgenstern formulated the expected-utiiity approach in terms of a simultaneous utility-probability axiomatization, which makes utility unique up to a linear transformation. This note illustrates, that there are situations in which it is convenient to consider utility or, more...
