Abstract
A discrete-time European options model with uncertainty of both randomness and fuzziness is presented, by introducing fuzzy logic to the stochastic financial model. The randomness and fuzziness in the systems are evaluated by both probabilistic expectation and fuzzy expectation, taking account of buyer’s/writer’s subjective demand goal. Fuzzy prices of European call/put options with uncertainty are given and their valuation and properties are discussed under a reasonable assumption. The meaning and properties of buyer’s/writer’s permissible range of expected prices are discussed in a numerical example.
