Measures for estimating transport vessels operators' subjective preferences uncertainty

The pseudo-entropy hybrid model is suggested as the measure of uncertainty of operators' subjective preferences. Because of the introduced relative prevailing preferences factor the proposed hybrid model has advantages comparatively to the traditional measures of uncertainty in the view of Boltzmann's or Shannon 's entropy. According to the relative dominating preferences index the pseudo-entropy varies within [-1...1] showing the sign and magnitude of the relative subjective assuredness. Analytical expressions have been achieved. The theoretical concept is illustrated with examples and graphs.
