Abstract

A computer visualisation application has been presented for the fuzzy evaluation of windscreen wiper systems which must satisfy several requirements. Some requirements are modelled by fuzzy sets, and a compensating arithmetic mean is utilised for computing the overall performance. A computer animation of the wiper mechanism motion and rainfall is shown, which enables experts, drivers and passengers to evaluate their degree of satisfaction and the correctness of their judgements. This fuzzy evaluation approach is illustrated by considering five “subjective” requirements (driver visibility, passenger visibility, wiped surface, visibility sensation and trouble sensation), and three design alternatives (traditional single- and double-wiped systems and a variable course system). The results are shown
