This paper describes a software tool to introduce fundamental concepts of reliability and fault tree analysis to engineering students. Students can fit common failure distributions to failure data. The data can be complete, singly censored, or multiply censored. The software computes distribution and goodness-of-fit parameters. The students can use the tool to validate hand calculations. Failure distributions and reliability values for various components can be identified and stored in a database. Various components and sub-systems can be used to build series- parallel or complex systems. The components data can also be used to build fault trees. The software tool can compute reliability of complex state independent and state dependent systems. The tool can also be used to compute failure probability of the top node of a fault tree. The software was implemented in Visual Basic with SQL as the database. It operates on the Windows 7 platform.

- Authors are able to enter into separate, additional contractual arrangements for the non-exclusive distribution of the journal's published version of the work (e.g., post it to an institutional repository or publish it in a book), with an acknowledgement of its initial publication in this journal.
- Authors are permitted and encouraged to post their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work (See The Effect of Open Access).
The copyediting stage is intended to improve the flow, clarity, grammar, wording, and formatting of the article. It represents the last chance for the author to make any substantial changes to the text because the next stage is restricted to typos and formatting corrections. The file to be copyedited is in Word or .rtf format and therefore can easily be edited as a word processing document. The set of instructions displayed here proposes two approaches to copyediting. One is based on Microsoft Word's Track Changes feature and requires that the copy editor, editor, and author have access to this program. A second system, which is software independent, has been borrowed, with permission, from the Harvard Educational Review. The journal editor is in a position to modify these instructions, so suggestions can be made to improve the process for this journal.
