- aggregation title "Strategic planning of optical telecommunication networks in a dynamic and uncertain environment".
- aggregation abstract "The planning of today's telecommunication networks is a very complex task, because the users and the demanded services as well as the costs to deploy and operate the network are evolving over time. Because of this reason, forecasts are made, which are inaccurate in nature. The dynamic and uncertain character of the input parameters needs to be taken into account during the network planning process. This PhD dissertation studies some important techno-economic aspects of the planning process, focusing on optical telecommunication networks, which form the basis of a lot of core networks of important telecom operators. Concerning the dynamic character of network traffic and equipment costs, our research compares the use of single period planning, anticipated planning and multi-period planning and their relation with investment selection techniques. Concerning the uncertain character of traffic demand and equipment costs, the well-known techniques using safety margins is evaluated and the use of Real Options thinking (originating from a stock option valuation technique) is illustrated. Furthermore, a lot of attention is given to the development of a cost model for a network operator, paying special attention to operational expenses. An activity-based cost model allows to quantify the operational expenses of the network operator. Therefore, different operational processes like maintenance, repair, service provisioning and pricing/billing are distinguished. The process-based operational expenditures together with the continuous costs of infrastructure (costs for floor space rental, energy consumption, etc.) constitute the total operational expenditures for the telecom operator. Finally, we indicate how the suggested cost models can be applied in a liberalized telecom market.".
