Economic optimisation of alternate routes in the East African telephone trunk network

Abstract

This dissertation discusses our economic method of optimising a telephone network with alternate routes by use of a computer. The method chosen uses a mathematical programming approach in terms of junction circuits and traffic carrying and overflowing properties of the chains involved in routing traffic between the exchanges. A mathematical formulation is given and the solution by means of a convex programming technique is also given. The use of this method has been illustrated by the three node trunk network presented for study.
