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.
