Maintenance history visualizer to facilitate solving intermittent problems

Abstract

A non-transitory computer readable medium () stores instructions readable and executable by at least one electronic processor () operatively connected with a display () and at least one user input device () to perform a device service support method (). The method includes: identifying attribute values () for attributes () of a plurality of previous service cases () from a service log (); identifying a set of relevant service cases () from the plurality of previous service cases by comparing the identified attribute values for the previous service cases with attribute values for a current service case () using a comparison metric () and a relevance threshold (); plotting, on the display, a timeline () of relevant service cases () of the set of relevant service cases as a function of calendar dates of the relevant service cases; providing a relevance graphical user interface (GUI) dialog () for user adjustment of the relevance threshold via the at least one user input device; and responsive to user adjustment of the relevance threshold via the relevance GUI dialog, repeating the identifying and plotting to dynamically update the plotted timeline on the bases of the user adjustment of the relevance threshold.
