Abstract:Some problems are existed in confirming the weighted value in the software quality model, for example, the method is relatively rough and how the abnormal value is rejected while judging the weighted value. Aiming at these problems, it is pointed out that the scientific hierarchy structure of quality characteristics and sub characteristics should be built based on the analytic hierarchy process. Through the construction of judgment matrix, single hierarchical arrangement, total hierarchical arrangement and consistency check, the comprehensive weighted value of sub characteristics of bottom quality will be confirmed. Then by the extreme judgment rejecting method, the abnormal judgment value will be rejected to avoid the unreasonable comprehensive weighted value. Finally, by adopting this method in the test of one certain communication system software, the scientificity and rationality is verified.
Abstract. Two exterior trajectory models of guided bomb in aircraft coordinate system (ACS) and body coordinate system (BCS) are built for simulation and analysis under different meteorological conditions. Simulation errors of different modelling methods are studied and analyzed to verify the rationality of modelling method adopted in this paper, which also indicates the efficient path to decrease simulation error and improve precision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
