Reliability Analysis of the 9020A and 9020D Central Computer Complex at the National Aviation Facilities Experimental Center.

Abstract

This report summarizes 4 years of reliability and maintainability assessments on the 9020 Central Computer Complex (CCC) at the National Aviation Facilities Experimental Center (NAFEC). The original version of the CCC (the 9020A system) was monitored for a 3-year consecutive period between June 22, 1966, and June 30, 1969. A later improved version (the 9020D system) was monitored for a 1-year period between October 1, 1971, and September 30, 1972. This report also discusses printed circuit card replacements which occurred in both the 9020A and 9020D systems during the total 4 years of reliability determination. In the case of the 9020D system, additional information on usage, scheduled maintenance information, and part failures is provided.
