The level of utilization of a nonbottleneck isdetermined by the throughput of the bottleneck非瓶 頸工序的利用水平由瓶頸產(chǎn)出決定3. An hour lost at a bottleneck is an hour lost for the total system 在瓶頸工序損失一小時相當(dāng)于整個 系統(tǒng)損失一個小時4. An hour gained at the constraint is an hour saved for the whole system 在瓶頸工序節(jié)省 1小時相當(dāng)于為整個系統(tǒng)節(jié)省 1小時 ﹒ 5. Bottlenecks govern both throughput and inventories 由瓶頸來管理產(chǎn)出和庫存TOC Operations Global RulesBelton Confidential 33TOC Operations Global Rules6. The transfer batch (to bottlenecks) may not and many times should not be equal to the process batch (at bottlenecks) 瓶頸工序的交收批量可以與非瓶頸工序的批量不相等7. The process batch should be variable not fixed (run whenever possible) 加工批量可以是變化的無須固定8. Schedules should be established by looking at all of the constraints simultaneously. 計劃須同時考慮各個瓶頸的情況而制定 .Belton Confidential 34Game Study Belton Confidential 35演講完畢，謝謝觀
