A Novel Ontology Approach to Support Design for Reliability considering Environmental Effects

الملخص EN

Environmental effects are not considered sufficiently in product design.

Reliability problems caused by environmental effects are very prominent.

This paper proposes a method to apply ontology approach in product design.

During product reliability design and analysis, environmental effects knowledge reusing is achieved.

First, the relationship of environmental effects and product reliability is analyzed.

Then environmental effects ontology to describe environmental effects domain knowledge is designed.

Related concepts of environmental effects are formally defined by using the ontology approach.

This model can be applied to arrange environmental effects knowledge in different environments.

Finally, rubber seals used in the subhumid acid rain environment are taken as an example to illustrate ontological model application on reliability design and analysis.
