ASSEMBLY LINE DESIGN (ALD) SUITE
The Assembly Line Design (ALD) Suite is an advanced and integrated Excel‑based industrial engineering platform that supports constraint‑aware assembly line design. It helps engineers and operations teams evaluate line configurations, balance work content across stations and operators, define line-side storage solutions, and understand the real impact of takt, product mix, operator coordination, and tooling constraints. ALD is part of the Dumontis Codification suite: practical tools that translate operational expertise into powerful, field-tested models that support better operations decisions.
Manufacturers face recurring operational pain points while balancing and designning their assembly lines. This is caused by limited access to proper methods and tools, the use of incomplete or theoretical approaches, and the abundance of fragmented spreadsheets. These issues appear on the shop floor and in engineering offices, creating instability, inefficiency, and misalignment. Typical shop floor challenges include:
Engineering and management teams face their own constraints:
These pain points create a strong need for a structured, realistic, and accessible environment for line design and improvement.
ALD Suite provides a complete, structured environment for assembly line design and improvement. Its modular architecture supports scalable adoption and enables teams to work concurrently across products, stations, operators, and materials. The system consists of interconnected modules that together form a comprehensive workflow:
This modular system ensures consistency, scalability, and efficient teamwork across the entire line design process.
ALD Suite differentiates itself through a unique combination of capability, accessibility, and realism. It provides engineering‑grade modelling without the cost, rigidity, or overhead of enterprise platforms, while avoiding the limitations of traditional spreadsheets. Key differentiators include:
These differentiators position ALD Suite as a credible, high‑value alternative to both spreadsheets and enterprise line‑balancing platforms.
CASE - VDL BUS GROUP
When VDL Bus Group began building the new generation of bus modules, the factory was driven more by effort than by design. All variants moved along a single mixed-model line that had grown organically over time, leading to long walking distances, unpredictable workloads, and constant logistical bottlenecks.
The first step was to untangle the factory. The team replaced the original line with three dedicated mixed-model assembly lines and rotated the entire layout by ninety degrees to straighten the material flow and eliminate the main logistical bottleneck. This structural redesign also made it possible to align team leader responsibilities with the value streams. “The moment we split the mixed line into three model-specific lines—and rotated the entire layout by ninety degrees—everything changed,” said the plant manager.
Next, the team used ALD to rebuild the line at a detailed level: incorporating actual task times, build sequences, task and skill constraints, tools, ergonomics, and line-side storage. “It’s the first time we have a single place where the entire line exists, based on real data from the genba,” said one of the engineers.
Flow stabilized. Logistics became predictable. Operators finally experienced balanced work instead of constant improvisation. And team leaders were able to manage the full value stream instead of isolated fragments. The result was a dramatic improvement in productivity—and a factory that felt calmer, clearer, and much easier to manage.
Curious how this approach at VDL Bus Group paved the way for a jump in productivity and a more stable process?
