The “fourth industrial revolution” is a natural result of technical and digital progress. The end of the 19th century saw the invention of the steam engine (changing over production to machine power) and industrialization. The 20th century began with the invention of the production line for more efficient production and only 80 years later, digitization with intelligent control of production processes (IT, hardware and software) followed. These three revolutions brought immense savings, but at the cost of individual products and shorter production times. Driven by the primary benefit to consumers – individual products at low prices – Industry 4.0 should once again offer the option of small batches with a higher degree of customization, cost-efficiently, on time and in the appropriate quality. PROXIA supports these new goals of the production industry with holistic, sustainable and cutting-edge MES solutions, consisting of innovative MES-Software and practical MES concepts.
