Opcenter Advanced Planning & Scheduling for Aerospace & Defence Manufacturing
Whether manufacturers are producing aircraft fuselage sections, armoured vehicles, helicopters, drones, naval systems or satellite structures, one challenge remains constant: complexity. Modern Aerospace & Defence programmes involve thousands of interconnected components, specialist resources, highly skilled engineers, long-lead materials and strict delivery commitments.
As this complexity increases, Opcenter Advanced Planning & Scheduling is enabling manufacturers to improve production planning, optimise finite capacity scheduling and gain greater visibility across manufacturing operations.
By connecting planning with execution, Opcenter Advanced Planning & Scheduling helps organisations respond faster to changing demand, improve resource utilisation and deliver more reliable production schedules.
Traditional planning methods are struggling to keep pace. Many organisations still rely on spreadsheets, disconnected systems and manual processes to manage production schedules. While these approaches may have worked in the past, today’s manufacturing environment demands greater visibility, coordination and control—capabilities that Opcenter Advanced Planning & Scheduling is designed to provide.
Applied Composites, a global supplier of composite solutions for airframes, engines, defence systems, launch vehicles and satellite structures, experienced these challenges as its operations expanded. By implementing Opcenter Advanced Planning & Scheduling, the organisation created a connected planning environment that improved scheduling accuracy, resource utilisation and operational visibility across its manufacturing operations.
Why Complexity Is Increasing Across Aerospace & Defence
The products being manufactured today are fundamentally different from those built even a decade ago. A single programme may involve:
| Manufacturing Challenge | Impact |
|---|---|
| Thousands of Components | Increased dependency management |
| Specialist Tooling | Greater scheduling constraints |
| Skilled Labour Shortages | Resource bottlenecks |
| Long Supply Chains | Increased delivery risk |
| Programme Changes | Continuous rescheduling requirements |
For Aerospace manufacturers, this may mean synchronising multiple aircraft assemblies simultaneously. For Defence manufacturers, it could mean coordinating armoured vehicle production, weapons systems integration and electronics manufacturing across multiple facilities.
In both cases, visibility becomes essential. Without a clear understanding of constraints and dependencies, organisations often find themselves reacting to issues rather than preventing them.

One Delay Can Create Multiple Consequences
Modern manufacturing is rarely linear.
A delayed component may impact tooling availability, labour allocation, downstream assembly activities and final delivery dates.
The larger the programme, the greater the ripple effect.
Applied Composites experienced many of these challenges while relying on spreadsheets and ERP-generated reports.
Although their ERP system could calculate material requirements, it could not effectively manage tooling constraints throughout the manufacturing process, creating significant scheduling limitations.
Moving Beyond Spreadsheets
One of the biggest limitations of traditional scheduling methods is that they often rely heavily on individual experience, disconnected systems and manual decision-making.
As production volumes increase, this becomes increasingly difficult to sustain. Planners may spend hours collecting information from multiple sources before manually creating production schedules. Supervisors are then required to determine priorities, coordinate resources and resolve conflicts while simultaneously managing day-to-day operations.
Opcenter Advanced Planning & Scheduling provides manufacturers with a connected planning environment, replacing spreadsheets and manual scheduling with intelligent, finite-capacity planning. By bringing production data, resources and constraints together in one solution, organisations can make faster, more informed scheduling decisions while improving visibility across their operations.
The result of relying on disconnected planning methods is often:
- Reduced visibility
- Increased operational stress
- Delayed decision-making
- Inconsistent scheduling outcomes
- Greater operational risk
By implementing Opcenter Advanced Planning & Scheduling, manufacturers can improve scheduling accuracy, optimise resource utilisation and respond more effectively to changing customer demand and production constraints.
Applied Composites recognised these challenges as its operations expanded and implemented Opcenter Advanced Planning & Scheduling to create a more connected, data-driven approach to production planning and scheduling.
The Importance of True Capacity Planning
A common misconception in manufacturing is that capacity equals machine availability. In reality, capacity is influenced by multiple factors:
Capacity Depends On:
- Labour availability
- Tooling constraints
- Operator capabilities
- Material availability
- Machine capacity
- Shift patterns
- Programme priorities
If any one of these constraints is ignored, schedules can quickly become unrealistic. This is where Advanced Planning and Scheduling (APS) solutions provide significant value. Rather than creating schedules based on estimates, APS enables manufacturers to create schedules based on actual operational capability.

From Reactive Planning to Proactive Decision-Making
One of the most significant advantages of modern scheduling technology is visibility. When organisations understand where every order sits within the production process, they gain the ability to make proactive decisions rather than reacting after problems occur.
Applied Composites implemented Siemens Opcenter APS to model all key production constraints, including materials, tooling, moulds and operator capabilities. This enabled the company to schedule production according to true plant capacity rather than estimates. The results were transformative. Schedules that previously required hours of manual effort could now be generated much more efficiently while providing greater confidence in delivery commitments.
Why Defence Manufacturing Faces Similar Challenges
The same principles apply across Defence manufacturing. Consider a modern defence programme:
| Programme Type | Key Constraints |
| Armoured Vehicles | Tooling, fabrication, specialist welders |
| Helicopter Manufacturing | Complex assemblies, skilled labour |
| UAV Systems | Electronics, testing capacity |
| Naval Systems | Long lead components, engineering resources |
| Satellite Structures | Precision manufacturing and integration |
Each programme requires the coordination of hundreds or thousands of activities across multiple departments. Without visibility, scheduling becomes increasingly difficult.
Delivering Better Outcomes Through Advanced Scheduling
Following implementation of Siemens Opcenter APS, Applied Composites achieved significant improvements across its operations.
Key Outcomes:
| Result | Outcome |
| On-Time Delivery | 96–98% performance achieved on average |
| Scheduling Efficiency | Reduced scheduling time from hours to minutes |
| Visibility | Improved understanding of constraints and downstream impacts |
| Decision-Making | Faster response to production changes |
| Capacity Planning | Greater understanding of labour and tooling requirements |
These improvements allowed the company to respond more quickly to change, improve customer communication and support continued growth.

Turning Complexity Into Competitive Advantage
Manufacturing complexity is not going away. If anything, it will continue to increase as Aerospace & Defence programmes become more sophisticated and supply chains become more interconnected.
The organisations that succeed will not necessarily be those with the most resources.
They will be those with:
- The greatest visibility.
- Those that understand capacity.
- Those that can evaluate change quickly.
Those that can synchronise resources, materials and production activities across increasingly complex manufacturing environments. Advanced Planning and Scheduling is rapidly becoming one of the key technologies enabling that transformation.
Bringing Greater Control to Complex Manufacturing Operations
As Aerospace & Defence programmes continue to evolve, manufacturers are under increasing pressure to deliver more complex products while maintaining performance, quality and delivery commitments. Whether producing aircraft structures, satellite systems, armoured vehicles, helicopters or advanced defence technologies, the challenge remains the same: ensuring the right materials, resources, tooling and people are available at the right time.
Organisations that can improve visibility across their operations, understand the impact of change before it happens and build schedules based on real-world constraints will be better positioned to reduce risk, improve delivery performance and support future growth.
The good news is that many manufacturers are already making this transition. By adopting advanced planning and scheduling solutions such as Siemens Opcenter APS, companies are gaining greater control over increasingly complex operations while creating more predictable, scalable and efficient manufacturing environments.
