Abstract: Based on inverse P-sets and random characteristics of elements translation, the concept and structure of inverse [P(ρ(σ),η(τ))]-sets are proposed. Then the relationship between inverse [P(ρ(σ),η(τ))]-sets and inverse P-sets is discussed, while the theorems on dynamic characteristics and random characteristics of inverse [P(ρ(σ),η(τ))]-sets are obtained.

Key words: inverse P-set, inverse [P(ρ(σ),η(τ))]-sets, random characteristics, dynamic characteristics
