Abstract:The development situation of Smart City operation management is analyzed from the perspective of information, including the scale-development of Smart City in the global view, the domestic pilot construction and information barriers, the strategic demand and technical challenge in the age of big data, and the integration of person, machine, and object promoted by the new generation information technology. Then, the connotation and confine of big data management of Smart City are defined, and a real-time information classification standard is put forward in seven dimensions: person, space, event, object, organization, area, and time. On this basis, a general framework of information coordination is structured in three phases including information starting, information flowing, and information arriving. Furthermore, information flow patterns of Smart City operation management and the adaptive optimization processes of information flow in city system are expounded detailedly. At last, a multidimensional coordination system for big data is put forward from the perspective of scientific decision.
