Overview
Function Analysis: use the function net or FMEA form to display the interaction between several system element functions.
The focus of the analysis is from OEM to first-tier suppliers and then to N-tier suppliers. The purpose of creating a function net or function matrix is to integrate the technical dependencies between functions. Therefore, it will support the visualization of failure dependency in the later stage. When there is a functional relationship between functions connected by hierarchy, there will be a potential relationship between related failures. Otherwise, if there is no functional relationship between functions connected by hierarchy, there will be no potential relationship between related failures.
Failure Analysis: according to whether the analysis is conducted at the system, subsystem or component level, failure can be considered as failure effect, failure mode, or failure cause.
Regardless of the failure effect, failure mode and failure cause, first of all, they are all failures, which belong to the continuous three-level structure, and are distinguished after the failure chain is established. To link the failure cause with the failure mode, we should ask why the failure mode occurs? To link the effect of failure with the failure mode, we should ask what happens when the failure mode occurs?
FMEA Hunter supports two net building ways: matrix net building can be checked one by one for elements, and it is suitable for occasions with moderate data volume; Tree net construction can transform the focus elements of net construction and cross-level links, which is suitable for the occasion of large amounts of data.
Function and Failure Matrix
The function failure matrix is used to create an association relationship: check whether there is an association relationship between the superior and the subordinate one by one according to the focus element. At the same time, you can display the focus elements and all the elements at the upper and lower levels on one screen. Suitable for occasions with moderate data volume
Tree-shaped Matrix
The tree matrix method is used to create association relationships: the focus elements of the network can be changed, and cross-level links can be used, which is suitable for large amounts of data.
