Due to increasingly complex office operations and production floor management, intelligent control systems and wireless networking capabilities have been evolving to suit the needs of the modern office and factory. Smart offices allow administrators to monitor and manage the office via using a web application 24/7. For example, administrators in smart offices and factories can now use a web application for arranging meeting rooms, setting the temperature, turning on/off the lighting and electrical appliance, tracking the water supply, sewage system and gas pipelines, and monitoring for security and power statistics. Smart manufacturing systems enable production facilities and logistics systems to smoothly operate without human interposition, which is no longer a vision only in the production environment. Smart factories allow the data acquisition and control of the production takes place in real time, and make better-informed decisions to optimize production.
