Achieving a System Operational Availability Requirement (ASOAR) Model Version 3 User's Manual

Abstract

The Achieving a System Operational Availability Requirement (ASOAR) model is a macro-analysis tool. It is basically used for an early-on Logistics Support Analysis (LSA) and macro-level Reliability, Availability and Maintainability (RAM) analysis. ASOAR can determine whether a weapon system operational availability (Ao) requirement is attainable. If attainable, ASOAR estimates optimal end item operational availabilities from the system requirement. As an early-on LSA tool, ASOAR requires only system and end item level input data, not Line Replaceable Unit (LRU) input data. ASOAR usage provides concepts for major logistics support savings in attaining a system operational availability requirement. It outputs cost effective logistics downtimes and LRU order fill rates at the most forward level of supply support for each end item and the system. It also outputs optimal end item Ao goals usable as the Ao input to an end item sparing to availability model or an end item maintenance concept optimization model....
