Embodiment Construction

[0044] Conditions for implementation: To realize a natural environment effect knowledge reasoning method based on hybrid reasoning in the present invention, it is necessary to rely on a natural environment effect ontology model that is not the content of the present invention.

[0045] Description of the implementation mode: the present invention is a natural environment effect knowledge reasoning method based on hybrid reasoning, the flow chart of the method is as follows figure 1 As shown, the specific implementation is described as follows:

[0046] Part 1: Case-based reasoning for constructing knowledge of natural environmental effects

[0047] Case-based reasoning is to retrieve the previous experience and similar cases of solving such problems from a large amount of knowledge according to certain rules, and judge whether it is suitable for the current problem to be solved, and finally give a solution after making appropriate corrections. or several reasonable solutions....

Abstract

The invention discloses a natural environment effect knowledge reasoning method based on hybrid reasoning. Through the method, implicit knowledge mining can be performed on structured explicit knowledge (e.g., an ontology model), the natural environment effect and reliability design analysis form dynamic connection, and natural environment effect relevant knowledge can be applied to actual reliability design analysis work. The method comprises the steps that 1, case reasoning of the natural environment effect knowledge is constructed, including case library construction based on feature vectors and a case reasoning method based on property similarity measurement; 2, rule reasoning of the natural environment effect knowledge is constructed; and 3, hybrid reasoning rules of the natural environment effect knowledge are designed.

Description

Technical field [0001] The invention provides a natural environment effect knowledge reasoning method based on hybrid reasoning. This method can carry out tacit knowledge mining on structured explicit knowledge (such as ontology model), that is, to find the knowledge needed by designers from these explicit knowledge. Through the way of knowledge reasoning, the natural environment effect and the reliability design analysis are dynamically linked, so that the relevant knowledge of the natural environment effect can be applied in the actual reliability design analysis. The invention belongs to the field of reliability and system engineering. Background technique [0002] The influence of the natural environment on the reliability of military products is becoming more and more serious, but the natural environment effect data is still lacking in systematic and rational application in the process of reliability design and analysis. In order to realize the application or reuse of...
