Software requirement analysis quantifying method and system

Abstract

Provided are a software requirement analysis quantifying method and system. The software requirement analysis quantifying method comprises the steps that a sample acquiring module uses basic processes as classification objects to acquire samples of classifiers, characteristic attribute values of items to be classified in each sample can be determined according to the characteristic attribute of one basic process in history data, an output category can be determined according to development time of the basic process in the history data, a classifier generating module uses the obtained samples as training sample training classifier models, a classifying module can determine all characteristic attribute values of the basic processes divided according to software requirements to classify through the classifiers, and accordingly the corresponding output categories, namely the development time, can be obtained. The software requirement analysis quantifying method utilizes the history data to generate the classifiers, introduces the characteristics of function points of module types to more accurately estimate software development time and has good effects on quantifying software development time and controlling the service life of software.

Description

technical field [0001] The present invention relates to software requirement analysis and quantification, and more specifically, relates to a requirement analysis and quantification method and system related to function point analysis (FPA: function point analysis). Background technique [0002] FPA mainly solves the problem of how to measure the software scale. FPA was proposed by IBM engineer Allan Albrech in the 1970s, and was subsequently inherited by the IFPUG method proposed by the International Function Point Users' Group (IFPUG: The International Function Point Users' Group). Function Point Estimation (Function Point Estimation) is a technique evolved from FPA for estimating project size. Through the ISO organization, a variety of function point estimation methods have become international standards, such as: the comprehensive function point method proposed by Alain Abran et al., the IFPUG function point method proposed by the British Software Measurement Associatio...

Problems solved by technology

[0012] However, when the above estimation method calculates the original function points, it relies too much on the tables obtained from the project experience of experts, does not take into account the influence of the module type to which the function points belong, and does not make proper and full use of historical data. Software development time is not accurate enough
