The theory of fuzzy sets and system has proved to be an effective tool in handling the judgment of uncertainty. Therefore, it is well suited to the problem of hydrosystem quality assessment. The main purpose of this paper is to present a fuzzy inference model which includes the fuzzy implication and reasoning. The model has a quite simple form, but it can well to describe the main procedure of the algorithms. Application of the model to a hydrosystem which deals with streamflow estimation based on the rainfall amount and the characteristics of the watersheds is also presented. An eminent result, comparing with the result from traditional multiple regression analysis, is shown which demonstrates the usefulness of the fuzzy inference model on the hydrosystem. |
