Aviation Readiness Requirements Oriented to Weapon Replaceable Assemblies (ARROWS)
0 stars out of 5 based on 0 user ratings.

​Multi Echelon/Multi Indenture RBS sparing model for aviation weapon systems. The ARROWS model is the Navy standard consumer-level planeside RBS model and will be used for all aviation systems. The Service Planning Optimization (SPO) model within the Navy Enterprise Resource Planning (Navy ERP) program will replace legacy ARROWS. Operational needs, logistics infrastructure, and hardware information are input into the model. The sparing to availability model calculates the number of each type of spare part to be kept at each maintenance level site in order to satisfy an Ao target value. The model divides the spares budget target by the failure rate for each spare part candidate. This creates an index representing readiness per dollar spent for each part. The part with the highest index is selected. The calculations and selections are repeated until the Ao target is reached, constrained by the spares budget target.
