Innovation cycles and market cycles are getting shorter and shorter. New products have to be put into production quickly and cost-effectively. At the same time, there is a growing trend toward customization of the products themselves. The result is that production lines have to be converted at ever-faster intervals. For help, engineers, planners, commissioning technicians, and plant operators can access digitalized models and data. With the rigorous digitalization of its engineering methods, Heitec - an Erlangen-based automation specialist - is showing how this approach can be used to reduce risks during planning, to commission plants faster, and to optimize processes during operation.
