Em sistemas de rede distribuída, é um dos problemas mais importantes como atribuir os arquivos aos servidores tendo em vista o custo e o atraso. É óbvio que existe uma relação de compromisso entre custos e atrasos nestes sistemas. Para avaliar a otimização de que o custo total é minimizado sujeito ao atraso total, apresentamos o Modelo de Alocação Ótima de Arquivos como programação inteira 0-1 e investigamos as características gerais em sistemas distribuídos. Neste modelo, introduzimos muitos parâmetros de custo e atraso para avaliar com mais precisão o custo total e o atraso no sistema. Na construção de sistemas práticos é necessário investigar o peso e a contribuição de cada parâmetro no custo total. É muito útil mostrar como estimar os parâmetros de custo e atraso com base nesta análise. Neste artigo, analisamos a sensibilidade desses parâmetros e deixamos clara a influência entre os parâmetros principais.

Abstract: In distributed network systems, it is one of the most important problems how to assign the files to servers in view of cost and delay. It is obvious that there is a trading-off relationship between costs and delays in these systems. In order to evaluate the optimization that the total cost is minimized subject to the total delay, we have presented the Optimal File Allocation Model as 0-1 integer programming, and have investigated the general characteristics in distributed systems. In this model, we have introduced many cost and delay parameters to evaluate the total cost and delay in the system more exactly. In constructing practical systems, it is necessary to investigate the weight and the contribution of each parameter to the total cost. It is very useful to show how to estimate cost and delay parameters on the basis of this analysis. In this paper, we analyze the sensitivity of these parameters and make clear the influence between principal parameters.
