방법론
선언된 유입·유출과 지속 시간으로 사용 가능 저장량, 명목 회전시간, 구간별 재고 연속성을 계산합니다. 명목 회전은 실제 수령, RTD, T10 추적자 접촉시간, 소독 CT가 아니며 이 도구는 T10을 계산하지 않습니다.
Usable storage = gross storage × user-entered usable fraction. Operational storage is separately entered as a declared operating-storage basis and remains a subset of usable storage.
Nominal turnover time = usable storage / average throughput; nominal turnovers/day = average throughput / usable storage.
Interval continuity uses Snext = Scurrent + (Qin − Qout) × duration. When physical limits are enabled, overflow is recorded above the maximum and supply shortfall below the minimum; the modeled endpoint is limited to the applicable bound.
Working storage swing = maximum modeled inventory − minimum modeled inventory, including initial inventory and all modeled interval endpoints.
