The use of Model Based Condition Monitoring for predictive maintenance programs is becoming increasingly popular over time. This method involves spectral analysis on the motor's current and voltage signals and then compares the measured parameters to a known and learned model of the motor to diagnose various electrical and mechanical anomalies.
The models have two basic types - prediction modeling and estimation modeling. 1.0 Overview of Software Reliability Prediction Models. These models are derived from actual historical data from real software projects. The user answers a list of questions which calibrate the historical data to yield a software reliability prediction.
A condition is shown to affect a decision's outcome independently by varying just that condition while holding fixed all other possible conditions. The condition/decision criterion does not guarantee the coverage of all conditions in the module because in many test cases, some conditions of a decision are masked by the other conditions. Using ...
Model-based voltage and current systems (MBVI systems): This is a technique that makes use of the information available from the current and voltage signals across all three phases simultaneously. Model-based systems are able to identify many of the same phenomena also seen by more conventional techniques, covering electrical, mechanical, and ...
In this way, it can for example anticipate certain actions, predict failure or maintenance, or optimize energy consumption in a self-regulating manner. That requires a predictive model inside the product itself, or accessible via cloud. This one should run very fast and should behave exactly the same as the actual product.
RAMP Simulation Software for Modelling Reliability, Availability and Maintainability (RAM) is a computer software application developed by WS Atkins specifically for the assessment of the reliability, availability, maintainability and productivity characteristics of complex systems that would otherwise prove too difficult, cost too much or take too long to study analytically.
Software maintenance is the modification of software after delivery. [1]As per the IEEE standard glossary of software engineering terminology, software maintenance refers to the process of modifying and updating software after its initial development and deployment, to correct faults, improve performance or other attributes, add new features to meet evolving user requirements, or adapt to a ...
Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor. [1] Software testing can determine the correctness of software for specific scenarios but cannot determine correctness for all scenarios. [2] [3] It cannot find all bugs.
