Determining what algorithm to use can be difficult for the new user. For that reason the following is given. All algorithms will give the same detection percentages.Only the order in which items are detected will change. Detection percentage is dependent on the tests utilized not the Algorithm. The two most used Algorithms are 1 and 5.
Number 1 "Detect malfunctions with the Fewest Tests" (the default) will utilize the largest ambiguity sets (tests with the most functions in them) first to determine detection. This will produce a shorter vertical Detection tree and much wider Isolation horizontal tree. - Detect Malfunctions with Fewest Tests
Number 5 "Prove Maximum Operation Before Detecting Malfunction"is the exact opposite. The smallest ambiguity sets (usually inspection tests of single items) will be utilized first to produce a deeper vertical detection tree with much shorter isolation horizontal tree.This is the most used Algorithm by eXpress users. - Prove Maximum Operation Before Detecting Malfunction
Number 3 "Detect Critical Malfunctions" is a good algorithm to use where the tests are using failure mode and/or failure effect tests to determine detection. This Algorithm can be used very effectively with the weighting factors to show the most critical failures at the top of the tree. Utilizing this algorithm with Isolation cutoffs can decrease the number of isolation tests utilized to breakdown an ambiguity set but may result in larger replacement sets. Cutoffs may be used where replacement down time is more critical than replacement size. For this reason helps for utilizing weighting Settings (used most often with this algorithm) will be include with this algorithm herein as well as with the isolation helps - Detect Critical Malfunctions
