Abstract
In
process of software architecture design, different decisions with system-wide
impacts are made. An important decision of design stage is the selection of
appropriate software architecture style. Since quantitative impacts of styles
on quality attributes have not been studied yet, their application is not
systematic. Since Reliability is one of the essential quality requirements of
software systems, especially for life critical ones, one of the main criteria
in choosing architecture style of these systems is high reliability. The goal
of this study is to quantify the impact of architecture styles on software
reliability that is desired quality of life critical software. We evaluate
styles through reliability block diagram method. First, the reliability
equation of each architectural style was computed using of Reliability block
diagram approach. Then, reliability rank of architectural styles is computed by
setting of the number of effective components in a transaction parameter in
reliability equation of architectural styles. The main innovation of this
article is quantification of impact of styles on software reliability that is
essential for style selection.
