Smart factories setup is speeding up as the COVID pandemic is restricting experts, buyers, and owners from traveling to factories abroad. That’s why factories are now investing in automation and digitalization equipment and tools. But there lies a peculiar challenge. A smart factory has a higher space utilization rate, which leads to less space being provided for the machines. For example, in the shoe industry, PPM (pairs per m²) is emphasized along with PPH (pairs per person) for factory performance measures.
