“…Therefore, the relationship between the total system reliability r and its components' reliability R(i) (i=1:6) can be stated as: r = F (r1, r2, r3,r4,r5,r6) = r1*r2*r3*r4*r5*r6. Suppose that the reliability cost coefficient of the components [6] Estimate the values of reliability parameters of different component (r1, r2, r3, r4,r5,r6) with which the total cost C (C ＝ c1+c2+c3+c4+c5+c6) is minimized. …”

The reliability allocation and minimum cost of component in a system can be used to solve the allocation problems in components based systems as well as applicable to modular systems. A method is simulated for allocating reliability to each component of a system with a view to minimizing the system cost on specific reliability. There is a need for component developer and users to make these data available to reliability estimator so that the derived results are usefully applied to practical systems. The simulation to show near optimal solution to the problem of selecting the component and comprising the software can be obtained with minimum cost. We simulate different sizes of components and their reliability with minimum cost in a system. Finally we give the importance of how to select reliability and cost of each component in Component-based software.

O objetivo deste artigo é apresentar um modelo simplificado para avaliação da qualidade de sistema de informação. O modelo está baseado na observação do comportamento do consumidor de bens e serviços, e enfoca os aspectos ambientais que influenciam o processo de tomada de decisão de tais agentes. Este artigo, além de apresentar um modelo capaz de prever demandas futuras de usuários reincidentes, mostra a importância da existência de métricas, objetivas, para o gerenciamento da qualidade durante o processo de desenvolvimento de sistemas de informação, descreve um modelo para avaliação de tais sistemas baseado nos princípios da utilidade, usabilidade e qualidade.

“…In the literature, reliability allocation has mainly concentrated on understanding performance factors of systems in design and development stages. There are various studies to optimize early-stage reliability allocation for software [3,22,25,34,35], network systems [4,21,23], and other mechanical or electromechanical complex systems [1,2,13,17,18,31,33]. In addition, more general methodologies have also been proposed to be applied in design and development of various systems.…”
