Abstract The problem of urban telephone planning is the problem of how to plan a telephone network in the new city. This type of problem is very suitable to be solved by an expert system approach. This thesis presents an expert system for Urban Telephone planning. The system accepts the geographic map of a city in the form of its streets and intersection nodes coordinates, the specifications of the available cable sizes, the maximum available switch size, and the cost information for both the cables and the switches. The system determines the minimum cost telephone network that satisfies the demand required by the subscribers. The system has been developed by first acquiring the domain knowledge involved in the design of such networks from experts in the Egyptian Telecommunications Authority ARENTO. Furthermore, some procedural knowledge have been incorporated in the system for developing the minimum connecting network of cables among a set of points. This knowledge is based upon an algorithm for urban telephone planning [17], which is a modification of the algorithm developed by Kan [13]. The system has been implemented using an expert system tool written in PASCAL [22] under the UNIX environment and customized for DOS environment within the framework of this research.
