The Expansion of the Toyota Production System: 1980s

• Learning Curve: $$y = ax^b$$, where y is the production time, x is the cumulative production quantity, a is the initial production time, and b is the learning curve index.
• Economic Order Quantity (EOQ): $$Q = \sqrt\frac2DSH$$, where Q is the optimal order quantity, D is the annual demand, S is the ordering cost, and H is the holding cost.
