Your team doesn't just get certified — they build a complete improvement ecosystem during the training itself. Not classroom theory: production-ready tools created on your live processes.
Optimizes product formulations where component proportions must sum to 100% (or 1), such as alloys, foods, chemicals, or plastics — common in injection molding or energy heater blends.
Key Principles: The response depends solely on relative proportions, not total amount. The design space forms a geometric simplex (triangle for 3 components, tetrahedron for 4+). Components cannot exceed their feasible range.
Main Design Types:
- Simplex-Lattice: Tests vertices (pure components), edges (two-component blends), and uniform blends. Simple for linear/quadratic models.
- Simplex-Centroid: Adds a center point (equal proportions) to capture curvature effects.
- Extreme Vertices: Handles real constraints (e.g., min 20% Component A, max 50% B); focuses on boundary points.
- D-Optimal: Computer-generated for complex constraints; minimizes prediction error across the design space.
Developed by Genichi Taguchi, these methods aim to design products and processes that are robust to variation and noise factors — minimizing defects without eliminating their causes.
Core Concept: Use orthogonal arrays to efficiently test multiple control factors at multiple levels, then evaluate results using the Signal-to-Noise (S/N) ratio to identify settings that minimize variation.
Key Elements:
- Orthogonal Arrays (L4, L8, L9, L16…): Structured experiment matrices that reduce the number of runs while maintaining balanced factor coverage.
- Signal-to-Noise (S/N) Ratio: Measures robustness — Smaller-is-Better, Larger-is-Better, or Nominal-is-Best depending on the quality objective.
- Control vs. Noise Factors: Control factors are adjustable; noise factors (temperature, humidity, wear) cause variation. Taguchi finds control settings that are insensitive to noise.
- Parameter Design: Optimizes factor levels to achieve target performance with minimum variation.
- Tolerance Design: Tightens tolerances only where needed after parameter design, balancing quality and cost.
- Loss Function: Quantifies quality loss as a quadratic function of deviation from target — any deviation from the ideal causes loss, not just out-of-spec parts.
Typical applications: Injection molding parameter optimization, energy systems, coating processes, electronics reliability — all areas covered by KEEPLEAN simulators.
A structured training program applying Lean principles across the entire supply chain — from supplier to end customer. Participants learn to eliminate waste, create flow, and build pull systems on real supply chain scenarios.
