Major advances in U.S. Navy logistics/readiness are being addressed through the use of Common Rates Computation System/Common Allowance Development System (CRCS/CADS) and Multi-Echelon Readiness Based Sparing (MERBS). MERBS is a business process and decision support system that provides the capability to achieve specified weapon system Operational Availability (Ao) or Full Mission Capability (FMC) goals and minimize investment in spares inventories. It can also maximize readiness at a fixed cost.
CRCS/CADS is a client-server system that provides the ability to update all aviation usage rates and turnaround times (ITATs) every quarter and to produce the needed allowances in a timely and flexible manner. CRCS/CADS with MERBS Workstation provides the ability to build allowances targeting single indenture and multi-indenture aviation readiness goals.
The MERBS Workstation and CRCS/CADS provide the evaluation tools to improve future equipment/weapon systems to optimize the readiness oriented logistics support infrastructure and to reduce the total cost of ownership.
Information is provided in this section about the features and benefits of this approach and the possibility of its use with other services legacy and modernized maintenance systems. CACI has already achieved significant program savings through various analyses using RBS and ME and MI RBS implementation conservatively estimated in excess of $643M.
The RBS Process
- Structured progressive process throughout lifecycle
- System and configuration definition and validation
- Engineering analysis - readiness assessment
- Data and rates development, integration and validation
- Sparing analyses
- Single Echelon (SE)
- Multi-Echelon (ME)
- Multi-Indenture (MI)
- Supporting budget analyses development
- Follow-on assessment
CACI was founded in 1962 as a modeling and simulation company. Our early private sector business was soon followed by relationships with the federal government, and especially the DoD involving various business functions and processes.
The natural evolution of these two brought simulation and modeling to bear on DoD problems such as military logistics, repair, maintenance, supply and readiness. This has led to numerous innovative approaches and technologies for logistics including key breakthroughs in readiness based sparing (RBS).
Historically, DoD has used demand based modeling to determine the appropriate consumer level of spares required to maintain a key equipments/weapon systems. Success was measured by fill rate.
Under the evolution to RBS the cost, readiness, reliability, maintainability and requisition response time for parts not available are considered to determine consumer or retail sparing requirements.
RBS is a business process and decision support system that provides the capability to achieve specified weapon system Ao or FMC goals and minimize investment in spares inventories. It can also maximize readiness at a fixed cost.
DoD and the U.S. Navy have voiced a need for the Integrated Logistics and Supply (ILS) community to help in dealing with
- Aging fleet sustainment
- Under investment recovery
- Optimization of recapitalization/reliability improvement
- Multi-echelon tools
- Cost reduction tools
