Applied Technical Research


  • World Class Manufacturing Technique for Automotive Assembly Optimization: In a case study at Fiat Group Automobiles' Cassino Plant, WCM was implemented to enhance flexibility and productivity in the Mechanical Subgroups ETU assembly process. The approach integrated 10 technical pillars, including Cost Deployment for stratified loss analysis via Pareto charts, Autonomous Maintenance with 5S protocols for workplace organization, and Logistics Optimization using Material and Flow Matrices for just-in-sequence (JIS) and just-in-time (JIT) commodity classification. Methods employed MUDA analysis to identify non-value-added activities (NVAA) such as walking and waiting, Spaghetti Charts for material flow mapping, and simulation tools like Flexim for ergonomic prototyping and scenario validation. Implementation followed PDCA cycles, targeting 25% NVAA and 5% low balancing level (LBL) losses, resulting in 75% direct labor productivity gains, 85% ergonomic improvements via rest factor metrics, and zero-forklift operations through ro-ro systems and advanced warehousing. Key innovations included Low Cost Automation for servo-assisted single-point picking and Value Stream Mapping for waste elimination across Muda, Mura, and Muri, enabling multi-model production on a single line.

  • World-Class Manufacturing and Productivity Through Complementary Bundles: This research explores WCM as a lean paradigm shift from Taylor-Fordist models, emphasizing process-based organization with cross-functional value chains supported by ERP systems, high-involvement practices like team-based problem-solving and multi-skilling via on-the-job mentoring, and ICT integration for real-time decentralization. Technical methods included factor analysis for bundling practices, Cronbach’s α for consistency, and econometric models with Heckman procedures to address endogeneity in productivity assessments. Empirical evidence from case studies such as NUMMI (GM-Toyota joint venture) and Japanese transplants demonstrated super-additive complementarities, where adopting bundles (e.g., Kanban with autonomation) yields lagged productivity gains of 3-7 years, as validated by longitudinal data from Bloom et al. (2011). Innovations lie in sequential adoption frameworks and micro-level analyses, promoting dynamic knowledge creation and competence building for sustained financial performance in diverse industrial contexts.  Resource: https://www.siecon.org/sites/default/files/oldfiles/uploads/2012/08/Leoni.pdf


  • Total Productive Maintenance Framework in SME Manufacturing: A 'light' TPM model was deployed in a resource-constrained SME, structured in plan-improve-sustain phases with pillars like 5S for visual organization, Autonomous Maintenance via checkpoint tables, and Kobetsu Kaizen using root cause tools such as Pareto and fishbone diagrams. Technical tools encompassed Value Stream Mapping for waste identification, OEE monitoring (Availability × Performance × Quality), and patrol audits for standardization. Challenges like shop floor resistance and breakdown reliance were mitigated through pilot implementations on critical equipment (e.g., LP20 machine), achieving OEE uplift from 54.23% to 66.90% with minimal costs (178 RMB per unit). Innovations included internal resource utilization for free-domain materials and Kaizen circles for continuous patrols, reducing setup times and losses by 18.6% in non-value-added activities.

  • Total Productive Maintenance in Malt Manufacturing Boiler Plant: At Asella Malt Industry, TPM targeted the boiler bottleneck with eight pillars, including 5S for housekeeping, Autonomous Maintenance for operator inspections, and Planned Maintenance for preventive schedules. Implementation involved preparatory education, core activities via Why-Why analysis and Poka-Yoke for error-proofing, and OEE calculation to benchmark against 85% world-class levels. Metrics showed OEE rising from 69.87% to 78.94%, availability from 90.99% to 96.67%, and downtime halving from 82hrs to 38.35hrs, with production exceeding plans by up to 10%. Innovative techniques featured holistic pillar integration for six-loss elimination (e.g., speed losses, defects) and Office TPM for administrative efficiencies, fostering multi-skilling and zero-accident environments through visual controls and kaizen registers.

  • Lean Six Sigma for Transformer Testing Efficiency at Magnelab Inc.: Utilizing DMAIC, this case addressed test equipment failures in current transformer production, aiming for 50% reduction over three months. Measure phase involved Minitab analysis of four-year data for normality and outliers via histograms and box plots, revealing low Cp indices. Analyze used VSM for workflow mapping and Fishbone for root causes like human error and MTBF/MTTR issues. Improve implemented SOP manuals for standardization, proactive soldering for part maintenance, and automated data collection. Control employed linearity charts for stability, sustaining downtime reductions. Innovations included integrating MTBF tracking with VSM for predictive planning, enhancing repeatability and quality in SME contexts.

  • Lean Six Sigma for Battery Cell In-Process Quality at Northvolt: In Formation & Ageing processes, Lean Six Sigma mapped inefficiencies using VSM to quantify lead times (3537.22 min total, 297.22 min non-value-added), Spaghetti Charts for motion wastes, and 5S for workstation consolidation. Data from interviews and surveys informed DMAIC, with FMEA for risk prioritization and Control Plans for deviation reactions. Solutions like Kaizen events and automated OCV/AC-IR accessories reduced non-value-added time by 18.6% to 241.8 min. Innovations merged Lean waste elimination (7+1 Muda) with Six Sigma data utilization for operator-led projects, minimizing defects and enhancing detection in high-tech battery manufacturing.
