Offering an approach on the basis of Bayesian network to evaluate the reliability of architecture in a family of software products

Software assembly-line is an important issue which puts a lot of emphasis on reusability.In the process of software assembly-line, as in the software production, architectural design begins after needs assessment and the possible alternatives to the architecture of the software are also considered.Nowadays, there are some methods such as feature RSEB, CONIPE and etc to assess the software architecture. Mostly these methods are not compatible with the principles of assembly-line architecture which is based on reusability. But the change set model is a model which is the most important one because it takes the different arrangements of items into account to achieve reliability. Each change set consists of some items which are next to each other in different products and each product consists of a combination of these change sets. State Machine can be used to display the general behavior of the system and Bayesian network can also be used to assess the reliability of each architectural.This paper presents a model which applies the Bayesian network to assess the reliability of assembly-line architecture. To achieve this purpose, the architecture is simulated first with an appropriate method, and then the assessment is done. The simulation results show significant improvement in comparison of the previous methods.
