Publication number: 20100241400Abstract: A method of statistical analysis is based on an accelerated degradation model for estimating the failure rate from a set of accelerated life data (e.g. stress, humidity, temperature, voltage, resistance, vibration, etc.). The method re-samples randomly distributed data and organizes it into subsets that may be ordered. The maximum is found for each subset. From the maximums a parametric LEV distribution is determined. Maximum Likelihood Estimation methods may be used to find the parameters employed in the determined LEV distribution. The failure rate is calculated using the determined LEV distribution of the sample maximums.Type: ApplicationFiled: March 20, 2009Publication date: September 23, 2010Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Amanda E.

Patent number: 7801703Abstract: An integrity management system predicts abnormalities in complex systems before they occur based upon the prior history of abnormalities within the complex system. A topology of the nodes of a complex system is generated and data is collected from the system based on predetermined metrics. In combination with dynamic thresholding, fingerprints of the relevant nodes within a complex system at various time intervals prior to the occurrence of the abnormality are captured and weighted. The fingerprints can then be applied to real-time data provide alerts of potential abnormality prior to their actual occurrence.Type: GrantFiled: November 13, 2008Date of Patent: September 21, 2010Assignee: Integrien CorporationInventor: Mazda A.

Patent number: 7797130Abstract: According to typical inventive practice, a baseline describing a statistical distribution is established for a set of historical occurrences of an event. Comparison is made between the baseline and at least one current occurrence of the same event. Any current occurrence that is anomalous vis-à-vis the baseline is considered a possible leading indicator. According to some inventive embodiments of graphical presentation of such comparison, at least one graphical baseline comparative display component is rendered that includes a “bar” (describing a historical statistical distribution with respect to a criterion pertaining to occurrence of an event) and a “slider” (describing one or more current occurrences of the event). The bar includes at least one band representing a statistical mean range, and at least one band representing a statistical outlier range. Situation of the slider along the bar indicates whether and to what extent the current occurrence(s) is/are anomalous vis-à-vis the baseline.Type: GrantFiled: December 20, 2007Date of Patent: September 14, 2010Assignee: The United States of America as represented by the Secretary of the NavyInventors: Eric J.

Patent number: 7797415Abstract: Application health is determined by calculating baseline deviation for one or more transactions based on past data having the same context as current data being examined. The performance data is generated in response to monitoring one or more applications that perform transactions during a time period. The performance data may include transaction metric data and the context data describing conditions under which one or more transactions were performed. A baseline is determined by predicting current or recent transaction performance data values using past transaction performance data associated with the same context. Based on the comparison of the actual and predicted data with the same or similar context, a deviation from the baseline value is determined for the transaction and reported, for example to a user through an interface.Type: GrantFiled: April 29, 2008Date of Patent: September 14, 2010Assignee: Computer Associates Think, Inc.Inventor: Zahur Peracha
