Despite the mathematical properties and algorithmic features of an interactive method, that method's success usually lies in the kind of information it requires from the decision maker. In some cases, this information constrains the decision maker. If she does not find it easy and comfortable to...

The bandwidth packing (BWP) problem is a combinatorially difficult problem arising in the area of telecommunications. The problem consists of assigning calls to paths in a capacitated graph, such that capacities are not violated and the total profit is maximized. In this paper we discuss the...

Optical fiber systems play an essential role in today's telecommunications networks. The recently standardized SONET (Synchronous Optical Network) technology has made rings the preferred architecture for designing survivable networks. The network design problem is very complex in nature, because...

The problem of expanding the capacity of a single facility in telecommunications network planning is addressed. This problem can be formulated as a time-dependent knapsack, when relevant information is assumed to be known. We introduce the use of scenarios to model uncertainty in key data. The...
