Four methods for quantitative analysis of uncertainty, . transfer function method, numerical value simulation method, confidence interval method and second order matrix method, are expounded. At last , the approaches for lessening uncertainty, . multiple objective programming, nonparametric approach, regression analysis and expert opinion approach are put forward. Key words:uncertainty risk assessment quantitative analysis 前幾年,懷疑者們一直認為,由美國科學(xué)院院士及工程院院士Frank Press 倡議并促成的國際減輕自然災(zāi)害10年(1990~2000年)意義不大。并預(yù)言,在開始的5年內(nèi),人們將只會爭論不休,不知道應(yīng)該做些什
