Abstract: The present study is an experimental exploration of the feasibilityof applying fuzzy mathematics forecasting the degree of preference forvarious commodities. The subjects' one-dimensional evaluation [R'_(ji)] and comprehensiveevaluation [B_j] for a certain commodity was obtained from experimentI. Then, the weight set [Ai] was derived from B_j=?[Ai·R_(ji)]. The subjects' one-dimensional evaluation[R"_(ji)] for another commodityof the same kind was obtained from experiment Ⅱ. Then, the weight ofone-dimensional evaluation [R"_(ji)] with [Ai] was obtained so that thesubjects' comprehensive degree of preference[Bj] for the second commo-dity could be forecasted. The experimentation proved that the procedure was feasible andmore precise and simpler than other methods.
