MERBS Workstation, CRCS/CADS

The CACI developed MERBS Workstation and CRCS/CADS provide the tools to evaluate future weapon system improvements, to optimize the readiness oriented logistics support infrastructure and to reduce the total cost of weapons system ownership. This is accomplished through spares optimization focusing on expanding this methodology to take advantage of best commercial practices such as premium transportation and Contractor Logistic Support (CLS)/Performance Based Logistics (PBL).

MERBS takes the RBS concept to an additional level providing a wide range of logistic support solutions (see Figure 2). MERBS is a highly flexible methodology that can be applied to new or existing systems, both aviation and ground, and to commercial and non-developmental items. MERBS recognizes the interaction between wholesale and retail inventories, using the Logistics Response Time (LRT) as the link to optimize the total inventory. It optimizes the positioning of the spares by trading off between retail and wholesale stockage decisions.

ME-RBS Inputs and Outputs

MERBS starts with the sparing decision based on RBS techniques including determining engineering-based criticality, projection of demand considering increases and decreases in system population. Using cost it then optimizes against a given readiness objective. Once readiness targets are established MERBS considers the item's Order and Ship Time (OST), wholesale requisition response time and transportation alternatives, and makes decisions on the mix of stockage positioning. These tradeoffs result in limiting inventory investments but ensuring a full range of coverage at both the retail and wholesale levels, while maintaining a given level of readiness.

Multi-Indenture RBS (MI-RBS) is an integrated spares computation that utilizes the weapon system parts breakdown, the parent/child relationships, to meet readiness objectives at least total cost. In support of a consumer chain that has a repair facility MI-RBS optimizes spares selection by trading off components with their repair parts, as well as trading off among components. This optimized spares selection and allowance based on maintenance capability and required system readiness has been applied successfully in provisioning and in the development of stockage lists for major USN and USMC systems. This includes the Aviation Consolidated Allowance Lists (AVCALs) and the Marine Aviation Logistics Support Packages (MALSPs). This tried and proven process can also be linked to wholesale in a multi-echelon role, thus giving a multi-echelon, multi-indentured readiness-based sparing model.

CRCS/CADS is a recently implemented client-server system (see Figure 3) that provides the ability to update all aviation usage rates and ITATs every quarter and to produce

  • Aviation Consolidated Allowance Lists (AVCAL)
  • Shore Aircraft Consolidated Allowance Lists (SHORCAL)
  • Consumables Consolidated Allowance Lists (CAVCAL)
  • Marine Corps PCSP, FOSP and FISP allowances

in a timely and flexible manner. It is project oriented supporting configuration management, rates updates, allowance computation and project workflow management through a series of key events. It assigns users roles and access, links data sources and defines business rules and controls for the overall RBS systems. It fully integrates with the MERBS Workstation and thus provides the ability to target single indenture and multi-indenture MERBS-based aviation readiness goals.
