Problems solved by technology

Traditional knowledge expression methods mainly include logical representation, semantic network representation, frame representation, and rule representation, but they all have certain limitations:
However, in the past equipment management, these historical information were often filed as documents, which failed to form database records for computer retrieval, and failed to realize the knowledge model management of equipment life cycle according to the requirements of knowledge management

specific Embodiment

[0051] The following is an example of formally defining the Equipment Structure Ontology (ESO):

[0052] Using the six-element method, ESO::=(Ce, Re, Pe, Fe, Ae, Ie)

[0053] Ce is used to describe the main components of the large-scale equipment structure, which can be formalized as Ce:={Ce 1 , Ce 2 , Ce 3 ,...}, a component may also contain several or more subcomponents, such as Ce 1 :={Ce 11 , Ce 12 , Ce 13 ,...}, of course, sub-components can also contain multiple sub-sub-components;

[0054] Re is used to describe the relationship between the concepts of the equipment structure, which can be formalized as Re:={Re (n)(m)} represents the relationship between sub-component class n and sub-component class m.

[0055] Pe describes the attribute set of the equipment structure concept, which is formalized as Pe:={pe n-1 ,pe n-2 ,pe n-3 ,...} represent the attributes of subcomponent n. Considering the characteristics of component structure information, the attributes ...

Abstract

The invention discloses large equipment MRO (maintenance repair operating) knowledge construction method based on large equipment. The method comprises the following steps: obtaining the MRO domain knowledge of the large equipment; and performing ontology expression of the MRO domain knowledge so as to construct an MRO knowledge ontology base of the large equipment. In the invention, ontology is introduced into the construction of large equipment MRO knowledge, and the MRO ontology knowledge is constructed by establishing a conceptual model and an ontology model and using a drawing tool, an ontology editing tool and an ontology description language; and the method realizes unitization, standardization, formalization and sharing of the domain knowledge, and is contributed to improving the knowledge management and operation level and increasing the enterprise competitiveness.

Description

technical field [0001] The invention relates to the field of large-scale equipment MRO knowledge construction, in particular to an ontology-based large-scale equipment MRO knowledge construction method. Background technique [0002] With the rapid development of information technology, especially the development of computer technology and network technology, the capacity, speed and quality of information processing have been greatly improved, and it is able to process massive data and perform rapid information processing. Both software functions and hardware implementation have made great progress. , so that artificial intelligence can be more widely used. Knowledge representation is one of the most active fields of artificial intelligence research, which is to study the form of knowledge about problems stored in the computer for processing. [0003] MRO is a general term for various manufacturing service activities such as repair, maintenance, overhaul and operation carrie...
