Part of the Studies in Fuzziness and Soft Computing book series (STUDFUZZ, volume 99)


For showing the imprecision of risk assessment in terms of probabilities, in this chapter we introduce the possibility-probability distribution (PPD). We focus on calculation and application of a PPD. Section 12.1 gives the definition of a PPD. Section 12.2 develops the method of information distribution forming an algorithm to calculate a PPD. Section 12.3 introduces the fuzzy expected value of a PPD to rank alternatives. Section 12.4 gives a real example in flood management to show the benefit of the ranking based on a PPD. We summarize this chapter in section 12.5.
