To achieve a cost-effective network deployment, employing state-of-art technical advances provides a practical and effective way to enhance system performance and quality of service provisioning. Cooperative transmission has been recognized as one of the most effective paradigms to achieve higher system performance in terms of lower bit-error rate, higher throughput, larger coverage, more efficient energy utilization, and higher network reliability. This dissertation studies the location planning for the deployment of broadband access networks and explores the great potential of cooperative transmission in the context of single-cell cooperative relaying and multi-cell cooperative transmission, respectively. The placement problem is investigated in two categories of network deployment environment, i.e., an existing wireless access network and a perspective broadband access network, respectively. In an existing wireless access network, to solve some practical problems such as the requirements of capacity enhancement and coverage extension, relay stations (RSs) are introduced in the network architecture. We propose two optimization frameworks with the design objectives of maximizing cell capacity and minimizing number of RSs for deployment, respectively. Mathematical formulations are provided to precisely capture the characteristics of the placement problems. The corresponding solution algorithms are developed to obtain the optimal (or near-optimal) results in polynomial time. Numerical analysis and case studies are conducted to validate the performance benefits due to RS placement and the computation efficiency of the proposed algorithms. To deploy a new metropolitan-area broadband access network, we explore the integration of passive optical network (PON) and wireless cooperative networks (WCN) under the multi-cell cooperative transmission technology. An optimization framework is provided to solve the problem of dimensioning and site planning. The issues of node placement, BS-user association, wireless bandwidth and power breakdown assignment are jointly considered in a single stage to achieve better performance. We also propose a solution to the complex optimization problem based on decomposition and linear approximation. Numerical analysis and case studies are conducted to verify the proposed framework. The results demonstrate the performance gains and economic benefits. Given a set of network parameters, the proposed optimization frameworks and solutions proposed in this dissertation can provide design guidelines for practical network deployment and cost estimations. And the constructed broadband access networks show a more cost-effective deployment by taking advantage of the cooperative transmission technology.

Standortentscheidungen sind der strategischen Planung zuzuordnen. In diesem Beitrag geht es um Standorte, die von Kunden aufgesucht werden und im Wettbewerb stehen. Aus der Sicht eines Kunden ist die Wahl einer Einrichtung ein diskretes Entscheidungsproblem. Derartige Entscheidungen können durch diskrete Wahlmodelle (zum Beispiel Logit-Modelle) abgebildet werden. Dieser Beitrag zeigt, wie deren Ergebnisse in die modellgestützte Standortplanung integriert werden können. Die Anwendbarkeit der Ansätze wird an zwei Fallstudien demonstriert. / Within the framework of strategic planning, location decisions must necessarily take into account competition factors. The customer’s choice is a discrete decision problem. In this paper, we highlight the opportunities for integration of the results of a discrete choice model (for example a logit model) into facility location planning. The approaches are applied to two different case studies.

<p>Предмет ове докторске тезе је туристичко уређење Старе планине. Циљ рада је утврђивање оптималног модела туристичког уређења простора за развој планинског туризма. Као најбољи, аутор сматра модел који се заснива на примени стандарда и правила туристичког уређења простора која се примењују у планирању референтних (успешних) планинских туристичких дестинација данас у свету. Правила и стандарди се односе на све елементе туристичког система који посебно укључује: туристичку инфраструктуру, туристичку супраструктуру, социјалну и техничку инфраструктуру и организациони модел развоја. Посебно је важно да се планирање уређења простора спроведе спровођењем стратегијског плана развоја туризма са активним учешћем свих зааинтересованих субјеката, чија улога је кључна у развоју туризма.

The goal of the essay is to define the optimal model of tourism spatial development for growth in mountain tourism. The author believes that the best model is based on the application of standards and rules of tourism spatial development applied in planning of reference (successful) mountain tourist destination in the world today. The rules and standards are related to all elements of tourism system including: tourism infrastructure, tourism superstructure, social and technical infrastructure and organisational model of development. It is essentially important to implement the spatial development planning by putting into practice the strategic plan of tourism development with the active participation of all interested entities that have the key role in tourism development. Various theoretic arguments are given to confirm the affirmed statements.</p>
