Inventory Optimization & Supply Planning

Optimize Your Inventory. Reduce Costs Increase Readiness.

Effective inventory optimization and resource planning is about managing complexity while making the best possible use of limited sustainment budgets. Consider a fighter aircraft fleet deployed across multiple bases and expected to operate at its required operational tempo. Decision-makers must ensure the right spare parts and logistics resources are available at each location to maintain readiness, without tying up excessive capital in inventory or driving unnecessary sustainment costs.

The core challenge is selecting the most effective sustainment and inventory strategy within the available budget. Organizations must balance readiness, risk, and cost when deciding what to stock, where to stock it, and how to respond to changing operational demands. Without clear insight into these trade-offs, inventory decisions can lead to reduced availability, higher lifecycle costs, or fragile supply chain performance.

The Challenge

Optimizing spare parts assortments, sizing, pooling and procurement timing across the system lifecycle is critical to sustainment performance and cost control.

Key pain points:

  • Inefficient spares planning causing overstocking or stockouts. Without a holistic view of spare parts demand across systems and locations, organizations risk overstocking in some locations while experiencing critical shortages in others.
  • Difficulty balancing costs with availability KPIs. It is challenging to understand how individual inventory decisions affect availability targets, lifecycle cost and operational risk.
  • Challenges in identifying downtime drivers. Complex systems, large sustainment networks and diverse operational environments make it difficult to determine what truly drives downtime and reduced system availability.
  • Managing shortages or new operational scenarios. Planning for shortages, supply disruptions or changing operational tempos is difficult without understanding how strategies such as pooling, redistribution or cannibalization affect availability and lifecycle cost.

     

Our Approach

With over 50 years of collaboration with defense operators and manufacturers, Systecon has developed a proven methodology for inventory optimization. This approach combines lifecycle cost analysis, advanced modeling and scenario based planning.

How We Solve It:

Optimization & Sizing: Calculating optimal stocking levels for each site to balance cost and readiness, enabling the development of an effective Recommended Spare Parts List (RSPL).

Performance validation: Simulating failure rates and operational tempos to forecast spare part consumption and validate inventory strategies and RSPLs.

Risk Mitigation: Identifying critical drivers of downtime related to system reliability, logistics constraints and resource availability, and evaluating potential mitigation strategies.

Scenario evaluation: Modeling complex operational scenarios to assess system capability and availability under different conditions, including degraded operational states where systems remain capable of performing most tasks but with reduced capability.

Scenario in Action – Inventory Optimization & Planning

A leading NATO naval systems OEM and its defense customer need to develop a fleet wide sustainment strategy for a new multi role frigate program. The program included strict availability KPIs, performance based logistics incentives and readiness requirements across multiple operational theaters, all within tight cost constraints.

How Opus Suite+ Could Help:

  • Forecasting & RSPL Validation: Simulate mission driven consumption to validate provisioning lists and recommended spare parts lists.
  • Inventory Optimization: Identify the optimal mix of spare parts that balances cost, risk and readiness.
  • Scenario Planning: Model peacetime, surge and crisis deployments to support resilient provisioning and inventory strategies.
  • Lifecycle Cost Insights: Evaluate the long-term financial impact of spares strategies.

Potential Outcomes:

  • Lower inventory holding costs while maintaining high availability at forward deployed sites.
  • Improved resilience to supply chain disruptions and surge demands.
  • Better alignment with performance based logistics KPIs and contractual availability targets.

Potential Value Delivered:

  • Reduced inventory costs.
  • Improved availability at critical locations.
  • Greater resilience in surge and crisis scenarios.
  • Stronger alignment with availability and performance based support objectives.
