Performance Prediction using Neural Network and Confidence Intervals: a Gas Turbine application

Silvia Cisotto, Randa Herzallah

Research output: Chapter in Book/Published conference outputConference publication


The combination of Condition Based monitoring
techniques with the predictive capabilities of neural networks
represents a topic of central importance when it comes to
maximizing production profits and consequently reducing costs
and downtime. The ability to plan the best strategy based on the
prediction of potential damaging events can represent a
significant contribution, especially for the maintenance
function. In fact, optimization of the management of the
equipment is a fundamental step to guarantee the
competitiveness of companies in the current market. In this
paper, a tool based on the implementation of Radial Basis
Function Neural Networks was developed to support the
maintenance function in the decision-making process. In
addition to providing an indication of the status of the
equipment, the current approach provides an additional level of
information in terms of predicting the confidence interval
around the prediction of the neural network. The confidence
interval combined with the prediction of the future state of the
equipment can be of fundamental importance in order to avoid
strategic decisions based on a low level knowledge of the system
status or prediction performance of the applied algorithm. The
developed tool is tested on the prediction of a naval propulsion
system gas turbine performance decay, where the statuses of
both the turbine and the compressor of the system are predicted
as well as predicting their confidence intervals.
