DMA definition

Discrete mathematical analysis (DMA) is an approach to studying of multidimensional massifs and time series, based

on modeling of limit in a finite situation, realized in a series of algorithms.

The basis of the finite limit was formed on a more stable character, compared to a mathematic character, of human idea of

discontinuity and stochasticity. Fuzzy mathematics and fuzzy logic are sufficient for modeling of human ideas

and judgments. That was reason why they became technical foundation of DMA.

Classical Set

• Classical set has a clear boundary between elements that do and don’t belong to the set.

• If U is universal set, then a classical subset A U is defined by the membership function μ(x) that takes only two values: μ(x) =1 for the elements belonging to A and μ(x) =0 for elements not belonging to A.

Fuzzy Set

• A is a fuzzy set in U if there is a map μ: U 0,1, that shows the degree of inclusion

of the element x into the fuzzy set A.μ(x) is called by membership function of the

fuzzy set A.

Fuzzy Sets Approach in Geophysics

Lofti Zadeh: A human being thinks not in terms of numbers, but rather in terms of fuzzy notions.

Норберт Винер: По-видимому, главное преимущество человека перед компьютером – это его способность оперировать с нечетко очерченными понятиями.
