Inventory Optimization

Links below lead to scripts related to various Inventory Optimization models and simulations.

The idea of this repository is inspired by Nicolas Vandeput and his book.

• Safety and Cycle Stock Calculation
  • What else has been calculated: average demand, standard deviation, CDF and PPF.
• Stock Simulation
  • What has been simulated: safety stock, cycle stock, stock in transit, overall stock and demand.
• Fill Rate Simulation
  • What has been simulated: fill rate, cycle service level and period service level.
• Cost and Service Level Optimization
  • What has been calculated: fill rate, cycle service level and inventory cost per several review periods.
• Gamma Distribution Calculation
  • What else has been calculated: skewness, offset skewness, up-to level, safety stock.
