| Abstract: | To solve the subjectivity and fuzziness question of software risk assessment completely depending on experts’ experience,the quantitative evaluation method for software risk based on evolutionary neural network model is proposed.Firstly,by researching software risk evaluation process,the software risk evaluation index system is proposed,at the same time risk factors by applying fuzzy theory is quantified,as evolutionary neural network input value.Secondly,evolutionary neural network model based on improved back propagation(BP) neural network is constructed,combining the improved particle swarm optimization algorithm(PSO) and back propagation(BP) neural network.Finally,the feasibility of the method on quantitative analysis for software risk evaluation is validated with practical application,by simulating the model and the improved algorithm. |
