A knowledge-based approach for managing urban infrastructures

This paper presents a knowledge e-based approach dedicated to the efficient management, regulation, interactive and dynamic monitoring of urban infrastructures. This approach identifies the data and related treatments common to several municipal activities and defines the requirements and functionalities of the computer tools developed to improve the delivery and coordination of municipal services to the population. The resulting cooperative system called SIGIU is composed of a set of integrated operating systems (SYDEX) and the global planning and coordination system (SYGEC). The objective is to integrate the set of SYDEX and the SYGEC into a single coherent system for all the SIGIU's users according to their tasks, their roles, and their responsibilities within the municipal administration. SIGIU is provided by different measurement and monitoring instruments installed on some system's elements to be supervised. In this context, the information can be presented in different forms: video, pictures, data and alarms. One of SIGIU's objectives is the real-time management of urban infrastructures' control mechanisms. To carry out this process, the alarm control agent creates a mobile agent associated with the alarm, which is sent to a mobile station and warns an operator. Preliminary implementation results show that SIGIU supports effectively and efficiently the decision making process related to managing urban infrastructures. (C) 2002 Elsevier Science B.V.
