Trade-off Weights Control Panel

Tune how a change in one gauge affects another. Positive = same direction; Negative = opposite. Range: −1 to +1

Context

The simulator models how improving one dimension of the supply chain often creates pressure on another. Each gauge (Cost, Service, Resilience, Efficiency, Complexity, & Cash) interacts with others based on real-world trade-offs. The default weights represent the direction & magnitude of these influences

  • Cost: ↑ Cost ↑ Service when targeted spend on inventory expedition or capacity; ↓ Efficiency; ↓ Cash; ↑ Resilience
  • Service: ↑ Service ↑ Cost & Efficiency
  • Resilience: ↑ Resilience ↑ Cost & Service, ↓ Efficiency, ↑ Complexity
  • Efficiency: ↑ Efficiency ↓ Cost & Complexity, ↑ Cash
  • Complexity: ↑ Complexity ↑ Cost & Resilience, ↓ Efficiency
  • Cash: ↑ Cash ↓ FG & RM inventory, ↓ Service; ↓ Cost via lean working capital discipline

Example chain reactions: Improving Efficiency lowers Cost & Complexity, freeing up Cash. Enhancing Resilience strengthens Service but may erode Efficiency & increase Cost. Pursuing Cash can squeeze inventories & sometimes Service unless offset by Agility or Accuracy
