Research Interests

Recent research:
The researcher’s work synthesizes lean manufacturing, optimization, and predictive maintenance across diverse industries, with a strong emphasis on uncertainty and quality control. Across publications, methodologies such as stochastic programming, MILP, Six Sigma DMAIC, and quantitative modeling are applied to production planning, in-line weight control, and process improvements in manufacturing systems. Several studies evaluate Industry 4.0-enabled measurement and virtual metrology to enhance dimensional accuracy and reduce waste in glass container production, plastics packaging, and shrimp farming. A recurring theme is integrating Lean tools (VSM, JIT) with quantitative models to minimize cost, improve stability, product quality, and customer satisfaction under uncertain conditions, while providing frameworks and benchmarks for replication in similar sectors. The impact includes operational excellence, improved reliability, and measurable economic gains, alongside guidance for practitioners and researchers on managing uncertainty in LM environments.
Key Topics:
  • Optimization, Operations Research & Decision Support
  • Manufacturing Systems, Maintenance, Reliability & Predictive Maintenance (PHM)
  • Lean Manufacturing under Uncertainty
  • Quality Control & Six Sigma (DMAIC)
  • Industry 4.0, Virtual/Smart Measurement & Metrology
  • Agriculture & Aquaculture Applications of OR
  • Environmental Monitoring & Sustainable Manufacturing
