KA-Band Reliability Improvement. Part III. User's Manual for TASA/DEPEND Program.

Abstract : This report contains details instructions for using the DEPEND computer program to evaluate dependability, availability, reliability and other performance parameters for avionics and other systems and subsystems on aerospace vehicles. The program is run as the evaluation step in a comprehensive system performance analysis. In this manual, extensive computer experience is not assumed, but the user should have a basic knowledge of computer usage, and a technical understanding of the functional relationships among components of the system to be analyzed, and the effect on system, subsystem, and functional assembly performance resulting from malfunctions and failures of the system components. Complete information is given for setting up the input data, obtaining a run and interpreting the results. Figures defining the punch card formats for input data are provided that can be used as data sheets. Examples illustrating the use of the program are also included. The DEPEND program is written in FORTRAN IV language for the CDC Cylber 70, 6000 Series and 7000 Series computer systems. (Author)
