Research On Software Product Line Theory In Domain Of Emergency Assisted Decision System

Accompanied by the huge demands of software, complex problems in software engineering like software storm and software crisis have emerged. Accordingly, theory of software product line has been the key research issue in software engineering.Combining emergency support in emergency support field, this thesis does an in-depth study on applied software plan theory. Extracting the specialty and future development of emergency support system on the basis of studies on software product line theory. This sets the base for the research questions and research findings in this thesis. The following have been done:First, Bringing up an software product line model. This model consists of EADS engineering and EDAS applied engineering, which correspond to different workshops of software product line. Works, like model extracting, scaffolding, and setting up reusable database of EADS’demand analysis in EADS filed, in EADS engineering session are the prerequisites of applied engineering.Second, Building extracting model of work piece for emergency support system. In accordance with demands in emergency filed, this thesis extracts work piece, builds a model, does a rank classification after evaluation, withdraw constraint among work pieces and correlation to upper work piece, and put it into work piece base.Third, Setting up an engineering core asset base for emergency decision making support filed, including core asset of database, GUI core asset, model core asset, reusable work piece base, etc, and analyzing the transferability and generality of some core assets. Exploring demands engineering and scaffolding plan etc. of emergency decision making support filed on the basis of software product line theory, and bringing up some key issues in EADS production line.In the end, based on software production line of emergency decision making support filed, an emergency decision making support system for Tianjin police is designed and carried out. By testifying extracted model, reusable base, and software production line model, experience and techniques are accumulated.
