Least cost route planning DSS for telecommunication operators

This article employs a mathematical programming model to solve the capacity planning problem of international direct dialling (IDD) services. Our study involves allocating forecasted IDD demand traffic to destination countries via partner suppliers at minimum cost. To facilitate its use, the model has been integrated into a decision support system (DSS). Evaluating the data provided by a telecommunication operators shows that the system can handle the problem very effectively and efficiently.
