We present a new method, called UTA, for multiple criteria ranking of alternatives from set A using a set of additive value functions which result from an ordinal regression. The preference information provided by the decision maker is a set of pairwise comparisons on a subset of alternatives A A, called reference alternatives. The preference model built via ordinal regression is the set of all...

Since the halophytes species have an important role in such ecosystem balance and they have been grazed by livestock as supplementary forage, the awareness of livestock's desire to grazing and their preference values of these species is of high priority. Regardless of the importance of halophyte species in the livestock feeding in Iran, there is less published research on the livestock grazing ...

the rate of time preference plays an important role in discounting instantaneous utility in economic growth models and also in calculating social discount rate in cost-benefit analysis. in empirical researchers, this rate is assumed to be constant. however, the rate of time preference might vary over time. this paper develops a new algorithm to estimate this rate as a varied coefficient for the...

This present study aims to compare how service brand preference influence service perceived value, customer satisfaction and loyalty in different countries—Japan and China. Moreover, this study purposes to explore whether countries’ image affect service brand preference of customer. Two customer surveys which were practiced in Japan and China were conducted to examine moderation hypotheses, whi...

When pigeons acquire a simple simultaneous discrimination, some of the value acquired by the S+ transfers to the S-. The mechanism underlying this transfer of value was examined in three experiments. In Experiment 1, pigeons trained on two simultaneous discriminations (A + B- and C +/- D-) showed a preference for B over D. This preference was reduced, however, following the devaluation of A. In...
