Applying robust optimization to capacity expansion of one location in telecommunications with demand uncertainty

Article Abstract:

A study was conducted to analyze the capacity expansion of a single facility in telecommunications network planning supporting demand uncertainty. The problem was examined using the robust optimization model. It was solved in two phases that were characterized by a dynamic programming recursion and a shortest path process. An algorithm was utilized to support robust optimization formulation of the feeder capacity expansion concern. A user-interface was then designed as a decision support system for network planning executives. Results indicated the effectivity of using an Excel-based interface to solve problems associated with capacity expansion planning. Findings also showed that the algorithm was sensitive to the optimum accumulated demand across all scenarios.

Cable-TV firm wants to test phone service

Article Abstract:

Comcast Corp files a request with the US Federal Communications Commission (FCC) to provide personal communications networks (PCNs) in five cities. Comcast, which is a major operator of cable television systems, is one of several cable companies that are expressing interest in determining whether or not their cable systems can be linked with cellular phone systems and carry telephone calls. Telephone companies are expressing opposition to cable companies moving into their market, but the cable industry indicates that a successful implementation of PCNs could lead to home telephones that are more mobile, lighter and smaller than current technology allows.
