Embodiment Construction

[0022] In order to facilitate those skilled in the art to understand and implement the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] The ReqIF (Requirements Interchange Format) model is a requirement model used to implement requirements exchange and sharing XML description, and CBFM (Cardinality-based Feature model) is widely used in product lines Variability modeling. In order to explain the present invention, ReqIF is used to describe the structured requirements, and CBFM is selected as the variability model to introduce the specific implementation of the present invention, so as to establish the trace relationship between the text requirements and CBFM, and load the requirement attributes to the corresponding features of CBFM , So as to optimize the configuration of features.

[0024] The following describes the implementation case system HandlingSystem. figure 2 The CBFM model of Ha...

Abstract

The invention discloses a production line configuration optimization method based on a tracking relationship between a requirement text and a variability model, relating to the field of software production line variability configuration. According to the method, a requirement framework of a structural requirement is built through conversion of the variability model, text requirements are processedby using an NLP technology, so as to allocate the text requirements to the requirement framework to build structural requirements as well as the tracking relationship between the requirement and variability model, and finally, requirement characteristics are introduced to the variability model, an optimization series of the variability configuration is realized based on constraints of the requirement characteristics and variability model. The method solves a problem that the production line requirement characteristics cannot be used for guiding production configuration, and provides basis forproduction line configuration optimization easily, effectively and intuitively, so as to better ensure preferred configuration of the production line.

Description

Technical field [0001] The present invention relates to software product line variability configuration, in particular, to a product line configuration optimization method based on demand and variability model tracking relationship. Background technique [0002] The software product line is a method proposed for realizing software reuse, solving software crises, and realizing the industrialized production mode of the software industry. This method uses the concept of software reuse to combine shared architecture, features, codes, construction and requirements. Software products are treated as the same problem space, so as to better apply software reuse technology and improve the efficiency of software development. [0003] In order to achieve software reuse and support for product evolution, the product line method process is divided into two basic stages: domain engineering and application engineering. Domain engineering is the stage of realizing the core assets of the product li...
