Identification of major components for integrated urban air quality management and information systems via user requirements prioritisation

Integrated environmental management and information systems are software applications with various components. In the current paper the identification of the major components of such systems is being performed with the aid of the prioritisation of user requirements. For this reason, the analytical hierarchy process is applied for an integrated urban air quality management and information system, which is developed as a portal for environmental information. Useful results are drawn regarding the relevant importance of the components of such systems and the sensitivity of the prioritisation during their selection as a function of their relevant cost and value.
