Software reliability allocation is an important subject of software engineering,which allocate certain reliability to all modules so that the system can reach the goal reliability.When designing software, engineers will estimate reliability of the software.If the software does not reach the goal, which modules should we choose to improve reliability and how much should we improve are what Software reliability allocation to handle. Software reliability allocation develops gradually recent years, however ,many reliability allocation methods allocate reliability to software without considering the cost of software. Some methods such as AHP considers the cost of software,but its algorithm is very complicated.In this article, we introduced a nonlinear programming model for reliability allocation. The model can minimize the cost of software, as well as guarantee that software system reliability can reach the goal. At the same time,we introduced genetic algorithm to achieve the optional result for the model,it proves to be a valid way.How to estimate model parameters is very important for a model,we introduce some methods to decide model parameters.To make our model more pratical,we need continue to make a good number of experiments.
