# Abstract:

This report is concerned with a computer simulation of a transformation scheme of distinct information chains derived and constructed in AD-680 214. The report describes the computer formalism of the transfer of information from the initial state to successive states. The program is written in Fortran and includes several subroutines. The entire program refers to statistically independent subsystems. In the first part of the report there are constructed programs for general subroutines, applied to the case in question the subroutine Constant, Random, and Mess Up. The flow charts of the computer program contain program Message, subroutine ENTV, subroutine ENTT, ENTS, RANDOM, PRT, etc. The programs are used to calculate numerically a few examples with completely arbitrarily assumed probability values. Two numerical examples are calculated following exactly the formalism and the sequence developed and constructed in AD-680 214. The calculations give the values of the entropies, sensitivity coefficients, etc. The last numerical example solved refers to the target recognition problem. In this example there are calculated the magnitudes of entropies in various environmental conditions. Author
