Embodiment Construction

[0024] The solution of the embodiment of the present invention utilizes the Causal Modeling technology (CausalModeling) used to describe the causal mechanism of the system and the Bayesian belief network to predict the characteristics of the software project, wherein the causal relationship model technology starts from the characteristics of the software project, according to the management of the software project Information to obtain various factors that directly or indirectly affect the characteristics of the software project and their causal relationship, because the causal relationship model technology can be very comprehensive, intuitive and easy to obtain the various factors that have a direct or indirect impact on the characteristics of the software project and their causal relationship , so the solutions of the embodiments of the present invention can comprehensively, intuitively and easily obtain various factors that affect the characteristics of the software project a...

Abstract

The present invention relates to a method and device for predicting the characteristics of a software item, wherein the device includes: an acquisition module, which is used to start from the specified characteristics of the software item, and use a causal relationship model to obtain information on the management information of the software item. Each factor and its causal relationship that have direct or indirect influence on the specified characteristics mentioned above; the establishment module is used to establish a Bayesian belief network based on the obtained various factors and their causal relationship; A Bayesian belief network for predicting specified properties of said software item. By using the method and device, various factors affecting the characteristics of the software project and their interrelationships can be intuitively and easily obtained.

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...
