This paper describes a method for evaluating a ship Coordinated Shipboard Allowance List (COSAL) with respect to ship reliability. It analyzes current supply support policy and shows that a change is needed to permit ship top level reliability requirements to be met. The methodology presented can be used for inventory level--reliability "trade-off" analysis, and it can be applied now at minimal cost using NAVSEC's TIGER Simulation Computer Program. TIGER would take the spares suite selected by Fleet Logistic Support Improvement Program (FLSIP) and evaluate the Reliability and Availability (R&A) of the ship against the project timeline. If the R&A parameters are unsatisfactory, the TIGER Output list of critical equipments is examined for the possibility of adding spares. Iterative TIGER runs are made until a satisfactory spares suite is determined. This methodology identifies areas where additional spares are required and also those where onboard spares can be reduced.
