Integrating new production processes into existing factory structures is one of the most demanding challenges in factory planning, particularly in regulated industries such as plastics processing for pharmaceutical products. Material flow, production conditions, and structural constraints must all be precisely coordinated and aligned.
In an existing facility, this challenge was successfully addressed as part of a completed brownfield project. New production lines were integrated into an ongoing operation without acquiring additional floor space. The objectives were to harmonize processes, achieve a lasting improvement in material flow, and simultaneously create a resilient foundation for future growth.
Material Flow Planning as the Key to Successful Integration
The foundation of the project was a comprehensive analysis of existing material flows. All transport routes, transfer points, and logistical dependencies were systematically recorded and evaluated, resulting in a transparent, end-to-end picture of the current state; including bottlenecks, overloaded areas, and non-value-adding transport paths.
The material flow planning focused on:
- The structured definition of appropriate transfer points between production and logistics, considering all relevant internal material movements
- The assessment of existing traffic and transport routes
- The identification of critical areas with optimization potential
On this basis, a future-state material flow concept was developed that demonstrably reduces the burden on production and ensures stable, reproducible operational sequences.
Design of Automated Transport Systems
Building on the newly defined material flow concept, various transport systems were systematically evaluated. The central challenge was to identify a solution that could be integrated into the existing building structure, accommodate future production growth, and at the same time meet increasing demands driven by skilled labor shortages, social sustainability requirements, and advancing digitalization.
Both conventional and automated technologies were assessed in order to develop an economically sound, yet flexible overall concept.
The evaluation specifically incorporated projected transport volumes and frequencies, spatial constraints, and existing traffic infrastructure. The result was a concept that reliably meets current operational requirements while providing sufficient flexibility to accommodate future developments.
Simulation Creates Planning Confidence
To validate the practical viability of the concept, selected transport and production processes were modeled in a dynamic simulation. Real-world process sequences, peak loads, and demand fluctuations could thereby be analyzed and assessed under realistic conditions.
The simulation provided reliable answers to the key planning questions:
- Do material flows remain stable even under increasing utilization?
- Where do bottlenecks arise, and how can they be prevented?
- Which system configuration delivers long-term process reliability?
This allowed the planning concept to be not only validated but also specifically optimized before any investment commitments were made.
In parallel with the technical design, a multi-stage master plan was developed, capturing both short-term adjustments and medium- to long-term expansion scenarios. This planning instrument gives the company clear strategic direction for the ongoing development of the site and provides a solid basis for future investment decisions.
From Existing Assets to Future Potential: Production Sustainably Advanced
The completed brownfield planning delivered a robust overall solution that performs convincingly both in daily operations and at a strategic level.
Key outcomes:
- Stable, simulation-validated processes for a reliable production environment
- A clear recommendation for an economically efficient and process-secure transport system
- Significant optimization of transport routes and operational workflows
- Increased production output within the existing footprint
This project demonstrates how even highly complex existing structures can be efficiently developed further through rigorous analysis, simulation, and targeted technology selection.
Conclusion
Brownfield factory planning bridges existing structures with new production requirements. Through systematic material flow analysis, realistic simulation, and a forward-looking transport system design, the result is a solution that is stable, flexible, and economically sustainable.
This reference project shows that production growth, process stability, and structural constraints need not be in conflict, if planning and simulation are applied intelligently.
