Data Analysis

• Collection of historical information. Identification of formats and data sources. Identification and classification of variables: numerical, nominal, sampling frequencies. Format, units and accuracy. Reports review. Contact with specialized staff.
• Data Mining in ascending complexity.
  • Data visualization.
  • Univariate statistical study
  • Data quality analysis. Cleaning data for analysis. Missing information replacement.
  • Resampling data analysis (increase or decrease sampling frequency).
  • Filters analysis.
  • Identification of time segments with expected and anomalous behavior:
    • Autocorrelation and cross correlation of time series. Distance measures between time series.
    • “Fingerprints” algorithms
    • Neural Networks
  • Multivariate analysis:
    • Multivariate visualization
    • Detection of correlation between variables
    • Principal Component Analysis
    • Grouping techniques
  • Classification:
    • Grouping
    • Neural Networks

Monitoring

• The workflow developed in the analysis phase is optimized to be suitable for real time monitoring, evaluating different strategies for data storage and computational requirements.
• Monitoring is performed using Aleph in its real-time monitoring version. This version of Aleph combines different algorithms running at once on their own “real time”, showing results by different real-time plots and gauges that perfectly describe the operation being monitored. Aleph handles the OPC standard.
• Aleph allows setting alarms policy sending SMS or emails to authorized recipients. It is available via web. Mobile version under development.
