This pilot study presents an implementation of utility calculation that is based on utility difference proportions. To conduct a utility calculation for a consequence, one needs to evaluate utility difference proportions and to calculate utility values. The application can help decision makers to compare consequences pairwise and make decisions easier regarding to the final output utility value for each consequence. On the other hand, the application is limited to a specific case with specified preference ordering. The application can be further developed into a more real interactive analytic decision-making support tool in the future.
