Ontology construction methodology for complex product design

Abstract

The invention discloses an ontology construction methodology for complex product design. The ontology construction methodology comprises the steps that requirements of knowledge needed by the design are analyzed, and the ontology using object, application background and achieving function are determined; according to the requirements and the function-behavior-structure combination, the complex product design knowledge is classified; a semantic relation framework for product design ontology construction is constructed, and the semantic relation in the complex product design is determined, wherein the semantic relation framework refers to the relation in a suggested upper merged ontology (SUMO) and the relation defined by a user according to product characteristics; UML modeling is carried out on a concept ontology and a design ontology; the concept ontology and the design ontology of a complex product are constructed; the ontology modification or improvement is carried out by adopting an ontology inspection and evaluation method. By means of the ontology construction methodology for complex product design, ontology construction is achieved in the field of complex product design, and a support is provided for design knowledge share and reusing.

Description

technical field [0001] The invention relates to an ontology construction method, in particular to an ontology construction method oriented to complex product design. Background technique [0002] Complex product design is a multi-level, multi-stage, step-by-step complex activity that requires repeated iterations, involving industry standards, design formulas, design pictures, design experience values, design processes, and other types of complex activities, including a large number of design tasks. Multi-agent collaboration is required. Complex product design has extremely high requirements for designers, and at the same time relies heavily on industry standards and previous design experience. Therefore, organizing and storing the existing general knowledge such as product design and industry standards, and discovering the design experience knowledge in the minds of experts and expressing it, so that the subsequent design can be shared and reused, will carry out product des...

Problems solved by technology

However, in practical applications, there are still some deficiencies such as non-standard knowledge representation, insufficient knowledge expression, disconnection between theoretical conception and actual realization, and the inability of described knowledge to provide effective support for knowledge sharing and reuse.
