| Abstract: | Propose an algorithm to optimize the strategy for an inventory system, minimize the storage cost with constraint of satisfying service level. Abstract the inventory system optimization problem into a stochastic optimization problem, combine Kriging regression and Monte Carlo tree search to solve the stochastic optimization problem efficiently. Apply this method into a real world example and get positive feedback. |

| Keywords: | supply chain management inventory optimization Kriging interpolation Monte Carlo tree search |
