OPUS10 – More than Spare Parts Optimization

To US defense and aerospace organizations, OPUS10 – one of the software tools in Opus Suite – is the standard for cost-effective, readiness-based sparing across DoD programs. Trusted by Lockheed Martin, the US Army, and major prime contractors, OPUS10 delivers realistic modeling of technical systems and support solutions, with rapid calculations that reduce spare part investment by 30% or more while increasing system availability. Used across Army, Navy, Air Force, and Marine Corps sustainment programs, it has become the tool of record for organizations that need to meet MIL-STD requirements and DoD readiness targets – without overinvesting in inventory.

Spare Parts Optimization for DoD Programs

OPUS10 is the primary tool used by US defense contractors and military program offices to answer the hardest sparing questions across complex multi-echelon supply chains. For organizations operating under readiness-based sparing requirements – from LSAR-driven procurement to PBL contract performance – OPUS10 provides the analytical foundation to meet targets at minimum cost.

OPUS10 is ideal for finding the most cost-effective answer to questions such as:

• What spare parts assortment should I stock, and how should I allocate it across depots, forward locations, and CONUS/OCONUS facilities to maximize readiness at lowest cost?
• My program has multiple readiness requirements that differ by unit, location, and system type. What is the most cost-effective assortment and allocation to meet them all?
• How should my spare parts solution be adjusted during a phased LRIP ramp-up or system phase-out under a DoD acquisition program?
• For each LRU or SRU, should it be repaired or condemned when it fails – and where in the supply chain should that repair occur?
• What will total spares investment cost against my contract availability target, factoring in DFARS cost constraints and performance-based logistics requirements?
  How does my solution perform under demand surges, lead time variability, or supply chain disruption scenarios?

Evaluation of Support Solutions for US Sustainment Programs

Beyond sparing, OPUS10 provides decision support across the full maintenance concept for US defense programs. Program managers, logisticians, and system engineers use OPUS10 to evaluate and optimize support solutions under US sustainment frameworks – from depot-level maintenance allocation to organic vs. contractor logistics support (CLS) trade-offs.

• What is the most cost-effective support organization structure for this DoD program?
• Where in the maintenance hierarchy should repairs occur to minimize total ownership cost?
• Should all or part of the maintenance be performed organically or outsourced under a CLS or PBL arrangement?
• How many forward-positioned warehouses are required, and where should they be located to support operational requirements?
• What is the most cost effective transport solution?
• How sensitive is the support solution to changes in failure rates, lead times, or operational tempo?
• How should the support concept evolve as systems ramp up to full operational capability or begin phase-out?

Evaluation of Technical Systems and Acquisition Trade-offs

OPUS10 is used extensively in US defense acquisition to evaluate alternative system configurations and support solutions during the Engineering and Manufacturing Development (EMD) and Production and Deployment phases. It enables program offices and contractors to answer:

• Which system design or configuration delivers the best supportability performance from a life cycle cost perspective?
• What is the most cost-effective component choice when weighing higher unit cost against improved reliability and lower sustainment cost?
• Which component upgrades or design changes are worth the investment based on modeled improvement in availability or reduction in total cost of ownership?

Modeling and Optimization Across Complex DoD Scenarios

OPUS10 is scalable across the full range of US defense program complexity – from small fleet analysis to large multi-echelon, multi-site programs with thousands of components across CONUS and OCONUS locations. Its optimization algorithms produce results in seconds even for complex scenarios. OPUS10 accommodates:

• Repairable components, consumables, and mixed populations across multi-echelon supply chains
• Scheduled and unscheduled maintenance, including condition-based maintenance applications
• Time-phased scenarios such as LRIP ramp-up, deployment cycles, and phase-out planning
• Item-specific support solutions and program-specific criticality levels
• Multiple performance requirements per unit, location, or system type – aligned to DoD availability thresholds and objectives
