| Outline of Final Research Achievements |
We proposed the replenishment policies for NAIJI production system with resilience. ①We paid an attention to AVaR (Average value-at-risk) in order to evaluate a big supply risk to happen at non-daily low frequency and expand this estimator to one for multi-period production planning. ② I developed the technique to make the flexible and resilient planning for NAIJI production system. Even if forecast is changing day by day under demand uncertainty, in the case that the sum of forecast for planning periods is same in all cases, we led the simple stock replenishment policy that is “We should keep the stock level at each periods being constant values without changing them case by case”.③ We developed the technique to estimate the potential risk at start of the planning period and to evaluate initial stock level based on the quantity of procurement from other companies in emergency. ④ We researched the classification of the NAIJI production system and basic characteristics.
