Based on the Monte-Carlo method, the ten-state Pink model of lipid membrane was completed by the dynamic Kawasaki-type processes of nearest neighbour exchanges of lipid molecules and vacancies in lipid chain lattice. The influence of the number and distribution of vacancies in membrane on its permeability was studied. The snapshots of microconfigurations of the dipalmitoylphosphatidylcholine (DPPC) membrane model obtained from Monte-Carlo simulation were analyzed. Temperature dependences of the area of vacancies in the membrane and regional probability of an ion transfer through interface region were determined
