DSM — Goods-to-Person Retrofit

Fourteen design activities for retrofitting goods-to-person robotics into a live distribution centre, listed by engineering discipline as the vendor's scope document lists them, computing that discipline order forces 10 rework loops where the real sequence needs 3 — a four-way slotting/racking/fleet/charging sizing loop plus the pick-station and labour-model pair.
