Condition Based Maintenance Plus

Condition Based Maintenance Plus (CBM+) is the application and integration of appropriate processes, technologies, and knowledge-based capabilities to improve the reliability and maintenance effectiveness of Department of Defense (DoD) systems and components. It’s established by DoD Instruction 4151.22 “CBM+ for Materiel Maintenance”.  At its core, CBM+ is maintenance performed based on evidence of need provided by Reliability Centered Maintenance (RCM) analysis and other enabling processes and technologies. CBM+ uses a systems engineering approach to collect data, enable analysis, and support the decision-making processes for system acquisition, sustainment, and operations. CBM+ falls under the umbrella of Total Life Cycle System Management (TLCSM). The goal of CBM+ is to perform maintenance only upon evidence of need. [1]

The Condition Based Maintenance Plus (CBM+) strategy: [2]

  1. Enhances maintenance efficiency and effectiveness and integrates all functional aspects of life cycle management processes, such as development, acquisition, distribution, supply chain management, and systems engineering.
  2. Establishes integrated, predictive maintenance approaches, which minimize unscheduled repairs, eliminate unnecessary maintenance, and employ the most cost-effective maintenance health management approaches.
  3. Implements an optimum mix of maintenance technologies (e.g., diagnostics and prognostics), RCM-based maintenance processes, and enablers (e.g., total asset visibility) within the integrated TLCSM framework.
  4. Enhances materiel availability by identifying the optimum opportunity to perform required maintenance, thereby increasing the number of assets in operational status.
  5. Improves materiel reliability through the disciplined analysis of failure data to develop modifications that will ensure equipment meets target performance standards within an operational context.
  6. Minimizes mean downtime by providing real-time maintenance information and accurate technical data to technicians and logisticians that will expedite repair and support processes and return equipment to operational status.
  7. Reduces ownership costs by eliminating unnecessary maintenance activities and accurately positioning required assets for an effective logistics footprint in support of warfighting requirements.

Condition Based Maintenance Plus (CBM+) Examples

  • Hardware: system health monitoring and management using embedded sensors; integrated data bus ·
  • Software: decision support and analysis capabilities both on and off equipment; appropriate use of diagnostics and prognostics; automated maintenance information generation and retrieval
  • Design: open system architecture; integration of maintenance and logistics information systems; interface with operational systems; designing systems that require minimum maintenance; enabling maintenance decisions based on equipment condition
  • Processes: RCM analysis; a balance of corrective, preventive, and predictive maintenance processes; trend-based reliability and process improvements; integrated information systems providing logistics system response; CPI; Serialized Item Management
  • Communications: databases; off-board interactive communication links
  • Tools: integrated electronic technical manuals (i.e., digitized data) (IETMs); automatic identification technology (AIT); item-unique identification; portable maintenance aids (PMAs); embedded, data-based, interactive training
  • Functionality: low ambiguity fault detection, isolation, and prediction; optimized maintenance requirements and reduced logistics support footprints; configuration management and asset visibility.

Condition Based Maintenance Plus (CBM+) Implementation

The implementation of the CBM+ strategy in DoD maintenance organizations should not be construed as primarily the application of new methods and technologies. The basis for CBM+ is more precisely a focus on improving the business process of maintenance with the principal objective being improved operational performance as a result of increased maintenance effectiveness in terms of greater productivity, shorter maintenance cycles, increased quality of the process, and better use of resources.
