Simulation for training lean manufacturing ranges from simple paperbasedor LEGO®-based games to larger scale simulation environments, forinstance push car assembly. Whilst such simulations may be suitable for educatingstudents, they are often less suitable for training industry workers. The latter groupis more diverse and is more used to intuitive learning than to formal instruction.Thus, it is important that the training environment for this group more realisticallyrepresents the work environment; otherwise training transfer will be limited. Forthis reason, a lean training environment that includes materials processing stationsas well as assembly areas was created. The stations exhibit some realisticbehaviour such as stochastic breakdowns.
