RBS Benefits

Where the early RBS analyses/implementation used one fixed value to represent the offsite delay time of all parts, the MERBS process determines the totals of retail and wholesale inventory costs for various wholesale levels based on delay time goals that achieve readiness objectives. MERBS also considers Variable Safety Level, Economic Order Quantity and repair level calculations based on total demand from other weapons systems. Thus a tradeoff is made between complex weapon system considerations, such as redundancy and mission planning, and the level of support achievable at both wholesale and retail levels.

MI-RBS provides the additional capabilities of trading off repairable components with their repair parts, thereby achieving reduced inventory investment.

Transportation impact is integrated into RBS calculations. There are two Order and Ship Times (OSTs) - one for providing direct delivery to operational forces when a spare is critical and one for routine stock replenishment. MERBS provides the ability to tradeoff OST with other parameters when alternatives need to be investigated to achieve lowest lifecycle cost.

MERBS is unique within DoD - it provides a level setting approach to reflect the changes in both wholesale and retail levels. MERBS can be used to isolate and analyze any RMS parameter, including the impact of proposed configuration changes. This marginal analysis capability to calculate readiness from numerous RMS parameters or budget changes using a phased mission is a powerful tool for making logistic support and budget decisions.

A comprehensive Business Case Analysis has been completed for the CRCS/CADS Project. This BCA conservatively estimated a 5% decrease in allowance investment for 12 aircraft carriers (CVs) as a $55.7M cost avoidance over four years in 1999 constant dollars. This translates into a 23:1 ROI over the contractor development costs of $2.5M. These projections have been verified recently through comparative analyses. Given the same list of candidates and using the improved rates projections allowance costs for various platforms (CVs, LCLASS and shore stations) have decreased anywhere from 6.7% to 18.1%. With the improved configuration capabilities the revised candidate files produce allowances at or less than previous costs with a greater range of candidates.

MERBS and CRCS/CADS can be a most valuable instrument for meeting many of today's logistics challenges in DoD and the USCG. These tools make possible the intelligent decision processes and management of multi-echelon and multi-indentured supply, distribution, point of repair selection, CLS/PBL, operations and support cost reduction, and readiness attainment.

The CACI RBS process can be used to evaluate the results of conventional logistics information systems and will interface with multiple legacy supply/logistics systems such as CCSS. Minimal effort is needed to adapt these proven tools and procedures to DoD/USCG weapons and information systems, contributing to the reduction of both the logistics footprint and the Total Ownership Cost.

CACI has already achieved significant program savings through various analyses using RBS and ME and MI-RBS implementation conservatively estimated in excess of $643M. This type of saving and efficiency is available to other services by the application and use of RBS from CACI.

The CRCS/CADS system also received a complimentary mention in a recent GAO report -

"The Marine Corps and Naval Inventory Control Point Philadelphia attribute their ability to provide rotor blades to using models to determine numbers and timing of spare parts and upgrades to sustain helicopter operations.

"The Marine Corps and the Naval Inventory Control Point Philadelphia maintain a five-year-old system, the Common Rate Computation System/Common Allowance Development System, which uses four-year historical demand data for the entire aircraft community for particular helicopters, engineering data and worldwide environmental factors to produce more accurate demand projections."
