Research And Application Of Risk Management In Software Project

With the development of the information society and with the raising of demanding of people to software, the development process of software project each link exists more and more complexity, uncertainty, imperfection, the risk of software project is more and more serious, the software project risk management appears especially important.This article studied the software project risk management basic theory and the domestic and foreign trend of development, Discussed the necessity of the risk management; On the base of through research software risk management theory and relative technology, Put an emphasis on the analysis and the induction to the two stages of risk recognition and the risk assessment; Proposed the improved risk management model on the base of analyzing many classical risk management model and synthesizing the characteristic of each model.The Bayes network model is one effective method to deal with uncertainty. The purpose of this article is to establish software project risk management frame on the base of The Bayes network model, Research the model, structure as well as the inference method of the risk Bayes network, Thus provided one systematized establishing model method for the software project risk management, Provided the new technical way and the realization method for solving the software project risk iteration and the dynamic characteristic question. Research the traditional risk analysis method, Proposed the method of risk quantitative analysis which comes from Bayes network model.Based on the above theory, Proposed software project risk evaluate model based on the Bayes network, Analyzed this model construction mentality and the principle, Refinement sub-model structure of each stage model, and proposed the solution and the concrete realization method for the key technologies and the difficulty of the model.Finally, realized the software project risk evaluate system on the base of software project risk evaluate model. These article researches the risk evaluate system flow of the software project, the database design, as well as the module design. This article has using the software project risk evaluate system to track the Three-dimension Discrete Element Method computation simulation software project , to appraise the potential risk of the software in the development process, to confirm the accuracy and the rationality of the risk assessment system.
