There is a method to measure quality of service in hotels. In related study [1] authors aggregate tourist opinions, measured on a scale from 1 to 10. Synthetic measure (indicator) of service quality in each hotel is calculated with the help of the aggregation operator.
Other study[2] proposed to use classical parameters EV, PV and AC to carry out the synthetic measure of project performance.
Different normalized stimulants and destimulants were used in research[3] to create synthetic measure that selects countries with the best and the worst levels of implementation of Europe 2020 targets.
