Abstract

The invention relates a method and a device for predicting software project characteristics. The device comprises an acquisition module, an establishment module and an evaluation module, wherein the acquisition module is used for acquiring each factor which influences the specified characteristic directly or indirectly and the causal relationship of the factors by utilizing a causal relationship model according to the management information of the software project through a specified characteristic of a software project; the establishment module is used for establishing a Bayesian belief network according to each acquired factor and the causal relationship thereof; the evaluation module is used for predicting the specified characteristic of the software project according to the established Bayesian belief network. By utilizing the method and the device, each factor which influences the characteristics of the software project and the interrelation of the factors can be acquired intuitively and easily.

Description

technical field [0001] The invention relates to a method and a device for predicting properties of software items. Background technique [0002] With the development of technology, software has become an important factor affecting national economy, military affairs, politics and even social life. Because software is so important, it is often developed as a software project. In order to control the software development risk, it is necessary to predict some characteristics of the software project to understand the situation of the software project. [0003] Currently, many schemes have been proposed for predicting the characteristics of software items. Among them, there is a scheme that uses Bayesian Belief Network (BBN: Bayesian Belief Network) to predict software item characteristics. The scheme first determines the interrelationships among the factors that affect the characteristics of software items, and then builds Bayesian belief networks according to the determined i...
