In this paper, a new interactive multiobjective target setting approach based on lexicographic directional distance function (DDF) method is proposed. Lexicographic DDF computes efficient targets along a specified directional vector. The interactive multiobjective optimization approach consists in several iteration cycles in each of which the Decision Making Unit (DMU) is presented a fixed number of efficient targets computed corresponding to different directional vectors. If the DMU finds one of them promising, the directional vectors tried in the next iteration are generated close to the promising one, thus focusing the exploration of the efficient frontier on the promising area. In any iteration the DMU may choose to finish the exploration of the current region and restart the process to probe a new region. The interactive process ends when the DMU finds its most preferred solution (MPS).

The results of an experiment to measure the performance of the Davidson and Soundex phonetic key compression schemes in finding sets of records representing the same individual in a moderately large radiology patient file, as compared to exact surname matches, are presented. This is similar to the problem of retrieving a record by name under the assumption that neither the search key nor the recorded key is accurately known. Both phonetic schemes perform similarly in obtaining extra matches and both outperform by a large margin the exact, name match. The results also indicate that the Davidson scheme is superior to the Soundex because it produces significantly fewer mismatches.
