Reliability Evaluation and Allocation of Object-Oriented System Based on Ant Colony Algorithm

In order to provide a rational reliability evaluation and allocation method with low development cost and testing cost for object- oriented systems, this paper discusses how to obtain the execution probability of system objects by the analysis of UML models, how to evaluate and allocate object reliability by using ant colony algorithm according to specific probability, and how to obtain the reliability values of every object and the system cost. This paper also presents a method to determine the reliability interval by using ant colony algorithm to obtain better allocation results. Experimental results show that the method can quickly get the specific object reliability and the minimal system cost. This approach fully takes into account the characteristics of object-oriented systems and is a reasonable reliability evaluation and allocation methods for object-oriented system.
