The article presents a description of a general approach to solving a class of design for network tasks supporting the activities of small and medium-sized companies based on modeling their business processes. Optimization of the infocommunication platform is formulated as a linear programming problem. The interpretation of the parameters of the optimization model and their relationship with the company's business processes and the characteristics of the infocommunication platform are given. An interpretation of the linear programming problem of the infocommunication platform is given as an optimization task in predicting changes in the input factors of the constructed model.

“…Ela é baseada num sistema real com dados existentes disponibilizados na internet [2]. A diferença dos trabalhos [16] e [8], onde são comparadas heurísticas de otimização num sistema ideal, neste trabalho foi utilizado um sistema real, onde foi verificado que o AG tem melhor desempenho que o SA. Embora os resultados alcançados mostrem que os algoritmos empregados ajudam efetivamente na melhoria do desempenho do sistema considerado, a implementação sem levar em conta antenas diretivas, Nós-B setorizados, informações específicas do terreno e a mobilidade dos usuários foi um limitante na obtenção de resultados mais adequados com a realidade.…”

Resumo-O nível de potência do Canal Piloto Comum (CPICH) do padrão WCDMA é uma ferramenta importante para conseguir um equilíbrio entre a cobertura e a capacidade dos serviços de voz e dados oferecidos num sistema UMTS. Define-se a razão de capacidade num Nó-B, como a razão entre a potência disponível para os canais de tráfego e a demanda total de tráfego para servir aos usuários dentro da área de cobertura. O objetivo deste trabalho é maximizar a razão de capacidade, minimizando o número de usuários sem cobertura. O problema resultante é multi-objetivo e técnicas de otimização numérica como o Algoritmo Genético (AG) e o Recozimento Simulado (Simmulated Annealing -SA) podem oferecer soluções válidas para este problema, dependendo de uma adequada configuração da heurística. Dados reais de uma rede UMTS na cidade de Lisboa são empregados nas simulações computacionais. As duas heurísticas conseguiram incrementar a capacidade média oferecida do sistema, minimizando a quantidade de usuários sem cobertura. Porém, a solução proposta pelo AG mostrou-se como a mais adequada para ser implementada.

There are many factors that have to be considered during planning phase of mobile radio networks. Some of the most important factors are: quality of service (QoS), cost of implementation and provisioning, traffic coverage ratio, and resource utilization. This paper analyzes economic aspects of 3G mobile radio network deployment and presents a planning model which explicitly takes into account some important factors such as QoS and investment cost. It emphasizes the impact of planning objectives and network element cost structures on 3G radio network deployment. The planning problem can be NP-hard, which is approximately tackled by a metaheuristic optimization method-tabu search algorithm. Numerical experiments with realistic problem sizes are conducted to describe some important aspects of efficient 3G network planning and demonstrate the efficiency and the practicality of the tabu search algorithm.
