Estratégias baseadas em análise multicritério para seleção de tecnologia de acesso de primeira milha em padrão ISDB-T
(Universidade Federal do Pará, 2012-11-23) SERUFFO, Marcos César da Rocha; FRANCÊS, Carlos Renato Lisboa; http://lattes.cnpq.br/7458287841862567
This thesis proposes the development of a planning strategy that combines: load characterization of a typical Digital TV, extraction of a weight vector from belief networks, and multicriteria decision making with analytical methods (TOPSIS and ELECTRE III), providing decision support at the service providers; in order to enable the optimal choice for the return channel technology (ADSL2 +, PLC, WiMAX and 3G), considering the typical load of an interactive Digital TV scenario, standard ISDB-T. The proposed strategy has five steps: definition of return channels and performance metrics; performance measurements of access technologies in real scenarios; scenario simulation; apply correlation techniques to generate the weight vector; and application of analytical decision making for choosing the best technology to be implemented in a given scenario. As main result a generic and flexible model is presented, validated with a case study for ordering the preference of the evaluated technologies.
