Multi-valued cognitive maps: Calculations with linguistic variables without using numbers

A concept of multi-valued cognitive maps is introduced in this paper. The expands the fuzzy one. However, all variables and weights are not linearly ordered concept, but only partially-ordered. Such an approach allows us to operate with partially-ordered linguistic directly, without vague fuzzification/defuzzification methods. Hence, we may consider more subtle differences degrees experts' uncertainty, than case. We prove convergence such give two simple computational examples which demonstrate using a uncertainty degree scale compared
