Didactic assembly line for learning Operational Excellence methodologies (Lean Six-Sigma)


ErmaLean is an evolving workshop that confronts learners with realistic industrial situations, such as the assembly of a mechatronic assembly. This enables them to apply the continuous improvement tools and methodologies used in industry. The learning process alternates between production phases and periods of performance analysis, using Lean and Six Sigma tools. The adjustments made on the basis of these analyses enable the quality, cost and lead-time targets set by the customer to be achieved. To implement ErmaLean, you need a workshop space of at least 100 m², so that you can configure the different layouts required for your activities.

Key points

A management role

Including a supervisory PC with Wi-Fi connection, a whiteboard and communication media

Dynamic storage

Dynamic storage system designed to hold all the containers required for three product variants

Five assembly workstations

Modular, depending on the performance being tested, with scalable management and control elements. Allows several set-ups to be tested (independent, in-line, U-shaped). Provides RFID traceability on assembly pallets and transfers between workstations

Assembly tools

Integrated assembly tools and built-in control, some of which are connected to the supervision system (measurement of screwing torques, dimensions, conformity tests, etc.)

Handling equipment

Handling, component supply and inter-station transfers are designed for the WIP volumes of the various locations tested, with evolving performance levels for the entire process


The evolution towards the assembly of other products is possible by the adaptation of the assembly trays and the modification of the documentations
