Method for analyzing conditions of technical components

A method for analyzing conditions of technical components in view of a rarity and/or an abnormality of a condition, the method comprises the following steps of:

• a) describing the conditions of the technical components in a behavioral input space being spanned by state variables, which are characteristic for the technical components;
• b) analyzing the condition of a technical component of the technical components in respect to other conditions of the technical component in the behavioral input space, whereby the rarity of the condition of the technical component is detectable, wherein step b) comprises the sub-steps of:
• determining a distribution of the conditions of the technical component in the behavioral input space for the analyzing of the conditions of the technical component;
• identify characteristic regions in the behavioral input space by using a distribution of the technical component in the behavioral input space;
• and
• determining a number of the conditions of the technical component in at least one characteristic region of the behavioral input space;
• c) analyzing the condition of the technical component also in respect to analyses of conditions of further technical components in the behavioral input space, whereby the abnormality of the condition of the technical component is detectable.

A method for observation of a state of a technical component by analyzing conditions of technical components in view of a rarity and/or an abnormality of a condition, the method comprises the following steps of:

• a) describing the conditions of the technical components in a behavioral input space being spanned by state variables, which are characteristic for the technical components;
• b) analyzing the condition of a technical component of the technical components in respect to other conditions of the technical component in the behavioral input space, whereby the rarity of the condition of the technical component is detectable, wherein step b) comprises the sub-steps of:
• determining a distribution of the conditions of the technical component in the behavioral input space for the analyzing of the conditions of the technical component;
• identify characteristic regions in the behavioral input space by using a distribution of the technical component in the behavioral input space;
• and
• determining a number of the conditions of the technical component in at least one characteristic region of the behavioral input space;
• c) analyzing the condition of the technical component also in respect to analyses of conditions of further technical components in the behavioral input space, whereby an abnormality of the condition of the technical component is detectable;
• d) obtaining different chronological conditions of the technical component by monitoring a state of the technical component over a period of time;
• and
• e) assigning the rarity and the abnormality for each chronological condition.

A method for failure prediction of a technical component by analyzing conditions of technical components in view of a rarity and/or an abnormality of a condition, the method comprises the following steps of:

• a) describing the conditions of the technical components in a behavioral input space being spanned by state variables, which are characteristic for the technical components;
• b) analyzing the condition of a technical component of the technical components in respect to other conditions of the technical component in the behavioral input space, whereby the rarity of the condition of the technical component is detectable, wherein step b) comprises the sub-steps of:
• determining a distribution of the conditions of the technical component in the behavioral input space for the analyzing of the conditions of the technical component;
• identify characteristic regions in the behavioral input space by using a distribution of the technical component in the behavioral input space;
• and
• determining a number of the conditions of the technical component in at least one characteristic region of the behavioral input space;
• c) analyzing the condition of the technical component also in respect to analyses of conditions of further technical components in the behavioral input space, whereby an abnormality of the condition of the technical component is detectable;
• d) assuming a failure of the technical component in dependency of a classification of the condition of the technical component as rare and abnormal.
