本课只做一件事：拿「人机工程学基础」做一次真实判断：按步骤走完，答案由推导得出而不是靠回忆。

Use Ergonomics Fundamentals in one real decision: follow the steps, derive the answer instead of recalling it.

本课不涉及：不新讲概念，也不做多题连练——只走一个场景。
Not covered here: No new concepts, no question drills — one scenario, walked through.

本课目标 | Learning objectives

  1. 按三步走完一个场景，并说出每一步的依据
  2. 区分「更有效」与「更先做」两类答案
  3. 把结论写回自己的术语表

  • Walk a scenario in three steps and justify each
  • Separate the more effective answer from the earlier step
  • Write the conclusion back into your glossary

    场景走一遍 | Walk the scenario

    电商仓库打包台：工人每小时把 12 kg 箱从地面托盘提上 75 cm 台面（水平距离约 50 cm），每小时 60 次，箱面光滑无把持边。员工投诉腰痛与「手滑摔箱」。主管申请「办一期搬举培训班」。

    E-commerce pack station: workers lift 12 kg boxes from floor pallets to a 75 cm bench (about 50 cm away), 60 per hour; the boxes are smooth with no coupling. Complaints: back pain and 'boxes slipping'. The supervisor requests a lifting-training class.

    1. 第一步：三要素定位——力（12 kg）、重复（60 次/时）、姿势（地面到腰 + 50 cm 远）同时高；把持差（CM 低）是雪上加霜 — Step 1 — locate the factors: force (12 kg), repetition (60/h) and posture (floor to waist, 50 cm out) are high together; poor coupling compounds it
    2. 第二步：用乘数定位杠杆——VM（地面起始）与 HM（距离 50 cm）是最差两项，它们决定 RWL 被打到很低；LI 大概率 > 2 — Step 2 — find the leverage: VM (floor-level origin) and HM (50 cm reach) are the worst two and crush the RWL; LI likely above 2
    3. 第三步：工程措施排序——托盘升高/升降台（VM→接近最优）、斜面或转台把箱子送到近身（HM 改善）、加装把持把手（CM 改善）；培训只作为补充 — Step 3 — rank engineering fixes: raise pallets or a lift table (VM), a chute or turntable to bring boxes close (HM), add handles (CM); training only as a supplement

    走完这三步再往下答题；答案不是背出来的，是按步骤推出来的。/ Work the three steps before answering — the answer is derived, not recalled.

    情景自测 | Scenario check

    考点应用Exam-point application

    这道题考什么：考乘数与工程措施的一一对应：改哪项条件、动哪个乘数。
    Tests multiplier-to-fix mapping: which condition, which multiplier.

    按上述三步，对 RWL 提升最大的一组措施是？

    Following the three steps, which set raises the RWL most?

    自编练习题，不是 BCSP 官方真题，也不能用来预测分数。 / Original practice item, not an official BCSP exam question.

    动手练 | Practice

    1. 为该工位写一份「评估 → 改造 → 复评」的三段计划（含时间点）。
    Draft a three-phase plan — assess, fix, re-evaluate — for this station with dates.
