MTBF and the Product Structure
In our previous post we discussed the different vendors and services offered for reliability testing and prediction. One of the important issues with relation to MTBF management is the product structure. The product structure is the hierarchy (or at least at first glance) of materials that make up an overall product. [...]

Determining MTBF and ReliaTech

Posted in MTBF, PLM, SAP, SPP, tagged , , on December 9, 2008 | 2 Comments »

Service Parts Forecasting
The main way service parts are currently forecasted is through the development of a MTBF. The MTBF is often developed from using similar parts and can be derived mathematically. However, there are also companies that perform physical testing to develop the MTBF number. One such company is called Reliatech.

Different Approaches
There are several different approaches to generating the forecast in MCA SPO. Each Location-Part combination can be configured to follow one of these approaches:

Computed: Based upon historical demand and leading indicators such as causals and installed population. Blends the history based and causal forecasts. The blending of these two forecast streams is called composite [...]

INTERFACE_TIME_PHASED_PART_MTBF parameter is used to indicate whether fixed or time phased engineering failure rate is being entered into SPO.
T = Engineering
The data is stored in he PART_TIME_PHASED_MTBF table
There are several types of MTBFs available:

Engineering
Forecasted
Composite
Engineering Flight Hours
Composite Flight Hours
Engineering Pressurizations
Composite Pressurizations
Engineering Hard Stops
Composite Hard Stops

Service Parts and MTBF Forecasting

Posted in Enigma, MTBF, tagged , on January 13, 2008 | 1 Comment »

Service parts for this airplane can be predicted based upon installed base and usage. The math for doing this is simple and present in multiple service parts planning applications. However, the problem is that most companies do not invest in the data maintenance.
What Type of Demand?
All service part demand is dependent demand. That is [...]
