We propose risk measures for resilience in the inventory system. It is based on an expected stock-out for planning horizon.
Resilience is powers of recovery against risk or business continuity. We research on risk measures in the inventory system to track the risk for resilience. Specially we investigate on risk measures concerned with
multi-period. At first, we explain the representative risk measures, that is, VaR,AVaR and clarify the relationship
between unfulfilled-order-rate and the representative risk measure. Next, we propose risk measures for multi-periods and clarify its validity by numerical experiences. Finally, future research is shown.
