8 definitions of mean time between failure

• MEAN TIME BETWEEN FAILURE (#RDS7925234)

A period of time which is the mean period of time interval between failures.

• MEAN TIME BETWEEN FAILURE 1 A (#RDS14647190)

The time duration between two consecutive failures of a repaired item.

International Electrotechnical Vocabulary (IEV) online database• MEAN TIME BETWEEN FAILURE 1 B (#RDS14647235)

The expectation of the time between failures: Note. - In English, the use of the abbreviation MTBF in this sense is now deprecated.

International Electrotechnical Vocabulary (IEV) online database• MEAN TIME BETWEEN FAILURE 1 C (#RDS14647280)

The expectation of the operating time between failures.

International Electrotechnical Vocabulary (IEV) online database• MEAN TIME BETWEEN FAILURE 1 D (#RDS14647325)

Total time duration of operating time between two consecutive failures of a repaired item.International Electrotechnical Vocabulary (IEV) online database

• MEAN TIME BETWEEN FAILURE 2 (#RDS14647415)

Predicts the average number of hours that an item, assembly, or piece part will operate before it fails.

Jones J. V. (1987), Integrated Logistics Support Handbook, McGraw Hill Inc., USA.• MEAN TIME BETWEEN FAILURE 3 (#RDS14647145)

For a particular interval, the total functional life of a population of an item divided by the total number of failures within the population during the measurement interval. The definition holds for time, rounds, miles, events, or other measure of life units.

MIL-PRF-49506 (1996), Performance Specification Logistics Management Information• MEAN TIME BETWEEN FAILURE 4 (#RDS14646965)

The average length of time a system or component works without failure.

• Integration of Life Cycle Data for Process Plants including Oil & Gas production facilities.

• Integration– Capability to span multiple applications– Restrictions specific to applications must be kept at

application level, not affecting the integration model

• Life Cycle– Data shall last for 25-75 years– HSE requirements– Accessibility to data

• Need to know what you have data about– Value of data compared to value of installation?– System independent

Key parts of ISO 15926-2

• Precise statements– Implemented in EXPRESS– Superseded by RDF

• Physical individuals and classes– serial numbered item and model

• 4D approach to change– Practical approach to life cycle

• Small number of key relationships– partOf, connectedTo, contains

• Formal approach to physical properties

Assets and facilities

• An asset is an item of equipment which has a material identity.– Hence an asset retains its identity when it is removed a

system and is maintained or used elsewhere

• A facility is a part of a system which has a functional identity.– A facility cannot be removed from the system of which it

is a part and used elsewhere.

• An asset is installed to provide, or act as, a facility.

Temporal parts

• A period in the life of an object is another object – a temporal part.

• A statement about an object which is true for a period of time, but not always, is made about the temporal part.

Relationships between physical objects

• part of– temporally– assembly

• connected to

• contains

there is nothing much else you can say

:A part2:partOf :B .

:A part2:connectedTo :C .

:A part2:contains :D .

but if you want to defined more relationships you can – as reference data

Classification

• what sort of thing something is

:MyAsset part2:classifiedAs adv:Model_ABC_V5 ; part2:classifiedAs part4:CentrifugalPump .

Part 2 has a vocabulary for classification.

Classification

• what sort of thing something is

:MyAsset a adv:Model_ABC_V5 ; a part4:CentrifugalPump .

Part 2 has a vocabulary for classification.It is built-in to the RDF/N3 representation

Specialisation

• relationship between sorts of thing
