Abstract : The report is Volume 1 of a three volume final report describing the effort to satisfy the program's objective for refining and demonstrating the feasibility of a combined analytical prediction technique for reliability and safety. The technique is entitled 'TAbular System Reliability Analysis (TASRA)', which was previously reported in AFFDL-TR-70-81, AD877179. Feasibility of the technique is demonstrated using a typical modern control system, the F-111 triple redundant, adaptive, pitch axis flight control system. A TASRA digital computer program is written in FORTRAN language and is described in detail for both batch and terminal use. This Volume 1 describes the refinement and demonstration efforts including a comparison of TASRA predicted and field experience data for reliability and safety of the referenced system. (Author)
