MARKETING DATA MINING AND MODELING
· Analyzed marketing data for AT&T-TCI to determine which current cable customers
are most likely to switch to digital cable in the next quarter, based on current cable,
telephony, and demographic risk factors.
· Created and validated a statistical (semi-Markov state transition) risk model to
predict product and account attrition among U S WEST customers.

cable over the next 15 years.
TELECOMMUNICATIONS NETWORK DESIGN AND OPTIMIZATION
· Created a new design for a backhaul network in Colorado that saved
AT&T Wireless over 20% on their monthly backhaul charges. The new design, based on
large-scale integer programming optimization, re-assigned traffic to hubs and recommended
adding two new hubs to reduce system costs.
· For Sprint PCS, analyzed market demand forecasts and switching and
interconnect costs. Created a 20-period network growth and capacity planning and
optimization model. Identified a way to save over $1M (approximately 10%) of network
capital expenses for a small city by reconfiguring the initial choice of switch modules to
allow a more efficient capacity expansion growth path. This capacity planning model has
been used at SPRINT/Cox California PCS since 1996.
· For Cox California PCS, created a backhaul network optimization
program, solved via a new genetic algorithm, that reduced monthly backhaul costs by over
10% through more efficient of digital circuits to hubs and more economical use of SONET
facilities.
· For PrimeCo Personal Communications Services, Ltd., created an
optimization model of Multi-Channel Controller Card assignment and inventory management to
reduce the costs of expanding network capacity through base station capacity upgrades.
