Description du poste

Overview

  • Department: Maintenance - Engineering - Production.
  • Profile: Industrial / Mechanical / Mechatronics students with interest in AI and data analysis.
  • Duration indicated: 06 Months (internship period: 4-6 months).

Objectives

  • Develop AI-driven solutions to predict failures on Zeta/Omega machines and enable a shift from corrective to proactive maintenance.
  • Improve key metrics such as reduction in unplanned downtime and increase MTBF (Mean Time Between Failures).

Data & Inputs

  • Collect and preprocess historical data: breakdown records, downtime logs, vibration signals, temperature readings, and other sensor data.
  • Validate data quality, handle missing values, and create labeled datasets for supervised learning.

Tasks & Methodology

  • Implement and compare AI/ML models (regression, random forest, neural networks) using Python or R.
  • Perform feature engineering (time-series features, statistical summaries, frequency-domain features from vibration data).
  • Train, validate, and test models; evaluate with appropriate metrics (precision, recall, F1, ROC-AUC, prediction horizon accuracy).
  • Propose and design a predictive maintenance schedule based on model outputs and risk thresholds.

Required Skills & Tools

  • Maintenance knowledge and familiarity with MTBF concepts and maintenance processes.
  • Data analysis & AI/ML experience in Python or R; familiarity with libraries such as scikit-learn, TensorFlow/PyTorch, pandas.
  • Experience with time-series data, signal processing (for vibration analysis) is a plus.

Deliverables & Expected Outcomes

  • A validated predictive model or ensemble capable of forecasting failures before they occur.
  • A concrete predictive maintenance schedule and recommendations for integration into existing maintenance workflows.
  • Documentation, source code, and a short deployment/hand-over plan for production use.
  • Measurable results: demonstrable reduction in unplanned downtime and documented improvement in MTBF.

Number of Interns & Supervision

  • Number of interns: 01.
  • Work under the Maintenance / Engineering team with guidance on data access and domain validation.
