Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments disclosed in the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] The invention discloses a satellite design knowledge ontology association scheme based on design process, constructs a design activity workflow model, and describes design knowledge from three dimensions of knowledge type, domain and process, and calculates the relationship between design knowledge and design activities based on domain ontology Relevance, to realize the connection between design knowledge and design activities. The invention takes the design process of the satellite as the main line, reorganizes the design knowledge by taking the design activity as the application scene, establishes a design task-oriented knowledge system, provides a basis for the designer to efficiently reuse the design knowledge, and provides a...

Abstract

The invention discloses a design flow-based satellite design knowledge ontology association method and system. The method comprises the following steps of: describing a design activity in a satellitedesign flow by adoption of a seven-element array; analyzing the seven-element array to obtain a design standard, a design specification used by the design activity, a design input and a design activity keyword; retrieving a design standard library according to the design standard and design specification of the design activity, and establishing an association relationship between a related designstandard and the design activity; determining a design file of the design activity according to the design input, and establishing an association relationship between an output design file and the design activity; and retrieving design knowledges from databases of a plurality of information systems on the basis of a domain ontology according to the design activity keyword so as to form a referenceknowledge set, and establishing an association relationship between the reference knowledge set and the design activity. Through the method and system, communication satellite development knowledgesare comprehensively controlled, and an innovative satellite development process is supported.

Description

technical field [0001] The invention belongs to the technical field of satellite research and development, and in particular relates to a satellite design knowledge ontology association method and system based on a design process. Background technique [0002] The current satellite research and development knowledge is scattered and disorderly, and lacks an organizational mechanism for reuse, which makes it difficult to share knowledge and support innovative research and development. It can be seen how to combine the characteristics of satellite development, carefully organize and systematize existing knowledge, organize and correlate various resource data, expert experience and other knowledge in multi-disciplinary fields, and build a knowledge system that covers and supports the entire process of satellite development , realize the association between knowledge and development process in multi-type knowledge base, so as to realize the comprehensive control of communication...
