Abstract:

This report presents the results of a study to develop a reliability prediction technique to estimate system complexity for application during the early conceptual phases of system development. The prediction technique is based on system performance data derived from design specifications, detailed parts summaries, and detailed handbook predictions using MIL-HDBK-217A on existing systems. The technique requires only basic design information e.g. detection range, RF peak power, etc. as input data, and is applicable to four major system categories radars, computers, displays and communications. Two measures of system complexity are estimated by the technique total number of electronic parts used in the system and system failure rate based on MIL-HDBK-217A. Multiple linear regression analysis was the basic tool used to develop the prediction relationships for each system category. The data base, detailed analysis and examples of application are presented in this report.
