Mixed-model assembly line simulator

Product mix changes everything. Simulate it before you move the line.

Flowcell helps lean teams model mixed-model assembly lines, variable work content, operators, buffers, and bottlenecks before committing to a batch-to-one-piece-flow redesign.

Model product families

Set up different product types with different routing, cycle times, and demand mix so the simulation reflects the real workload.

Watch constraints move

The bottleneck is not always the same station. Flowcell shows how queues, utilisation, and throughput change as the mix changes.

Compare future states

Try one-piece flow, smaller batches, more operators, different buffers, or a new balance before committing real labour and floor space.

Built for mixed-model flow, not spreadsheet theatre

Averages can make a proposed line look balanced when the real product mix will behave very differently. Flowcell makes the future state visible by running the work through the line, showing where WIP forms and where capacity is being lost.

What happens when high-work-content products arrive together?
Which operator becomes overloaded under the proposed mix?
Does one-piece flow actually improve throughput?
Where does a small buffer help, and where does it hide the problem?

For batch-to-one-piece-flow projects

Flowcell is especially useful for smaller manufacturers with a mix of products who want to move away from batch production. Build a quick model, run the proposed future state, and use the result to guide the next workshop or line trial.

Best-fit scenarios

Assembly cells, product families, shared operators, feeder trips, sub-assemblies, buffers, and practical line balancing decisions where the answer needs to be understood quickly.
