A new\u00a0reliability engineering search tool<\/a> was recently added to the Reliability Analytics Toolkit<\/a>. This tool indexes, on a page level basis, approximately 30,000 pages from various reliability engineering “standards” (government standards, handbooks, guides and reports related to reliability, maintainability, availability, safety, etc.). \u00a0The tool provides a more comprehensive\u00a0search capability than the Google Custom Search box at the top of each page, which only outputs pages ranked high by Google, but not necessarily\u00a0all pages that contain a particular set of words.<\/p>\n

For example, if interested in an example of a reliability calculation using the Weibull distribution, the 1000+ page Electronic Reliability Design Handbook<\/a> might be a good place to start. Selecting the checkbox for m-h-338v1 and entering the words\u00a0weibull analysis example<\/span> in the search box:
\n\"\"<\/a><\/p>\n

results in this set of words being found on five pages, as shown in the picture below:
\n\"\"<\/a><\/p>\n

The tool provides feedback as to the frequency of words within a given document, as shown above, providing some indication of words the user may want to add or subtract from a given set of search words. \u00a0Actual links from the search are shown below, with the first and last being the most relevant (basically around pdf page 500 in the document). \u00a0Each individual page is contained in a single web page and\/or pdf file, thereby allowing for the easy sharing of only the most relevant pages by a simple copy\/paste into an email message, or by saving specific pages locally.
\n1.\u00a0MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_505.htm
\n2.\u00a0<\/a>MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_115.htm
\n3.\u00a0<\/a>MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_538.htm

\n5.\u00a0<\/a>MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_499.htm<\/a><\/p>\n

The tool also provides different out options, such as “pdf only” links:
\n1.\u00a0MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_505.pdf
\n<\/a>2.\u00a0<\/a>MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_115.pdf
\n<\/a>3.\u00a0<\/a>MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_538.pdf
\n<\/a>4.\u00a0<\/a>MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_866.pdf
\n<\/a>5.\u00a0<\/a>MIL-HDBK-338-V1_Electronic_Reliability_Design_Handbook_15_Oct_1984_pp_499.pdf<\/a><\/p>\n

The pdf link option does not allow for easy navigation to nearby pages, but may be useful for some mobile device browsers that cannot display a pdf page embedded in a web page.<\/p>\n

What are the failure modes for a chip capacitor?<\/h1>\n

Want to know how a ceramic chip capacitor might fail, the 1200+ page NASA Parts Application Handbook<\/a> is a great place to start. \u00a0Selecting the checkbox for\u00a0m-h-978 and searching chip capacitor failure mode<\/span>:
\n\"\"<\/a><\/p>\n

quickly turns up two relevant pages pertaining to failure modes of ceramic capacitors, but not specifically limited to “chip capacitors”:
\n\"\"<\/a><\/p>\n

1.\u00a0MIL-HDBK-978_NASA_Parts_Application_Handbook_1_Sep_1989_pp_73.htm<\/a>
\n2.\u00a0MIL-HDBK-978_NASA_Parts_Application_Handbook_1_Sep_1989_pp_72.htm<\/a><\/p>\n

Comparing to Google Custom Search<\/h1>\n

Performing the same search with the Google Custom Search, turns up no results at all:
\n\"\"<\/a><\/p>\n

This is despite the fact that the NASA Handbook 978 pages have been indexed and the words do appear on the two pages:
\n\"\"<\/a><\/p>\n

Using the Google Custom Search, but searching just on capacitor failure mode does turn up numerous results from MIL-HDBK-978, but not, as of this date, pages 72 or 73 shown above. \u00a0This is why the tool is considered a bit more comprehensive, or exhaustive. \u00a0If the words are on a page, this tool will list the pages (subject to optical character recognition\u00a0limitations when dealing with poor quality documents).
\n\"\"<\/a><\/p>\n

Using the Google custom search option to search\u00a0ceramic capacitor failure mode<\/span> does lead to page 72, in this particular case; however, in other cases relevant content seems to be missed.<\/p>\n

 <\/p>\n

Want to know the failure modes of a ball bearing?<\/h1>\n

The 400+ page Handbook of Reliability Prediction Procedures for Mechanical Equipment<\/a> is a great place to start:
\n\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

As can be seen from clicking on the results below, the “Page score” ranking algorithm puts the first two links, which are the most relevant, at the top of the list. \u00a0The remaining links all contain the search words, but are much less relevant. \u00a0The most relevant, is the second link, page 158 of the handbook, which contains a nice summary of the various ball bearing\u00a0failure modes and mechanisms.
