Production lines, queues & inventory — how work flows through a factory or system and how it is optimized.
Move two task boundaries across a three-station pump assembly line and compare cycle time, takt, balance efficiency and idle work content.
Run a filler, capper and labeler with finite accumulation lanes and see which machine blocks, starves and sets line throughput.
Vary arrival and service rates at a single-server desk and compare the observed queue with stationary M/M/1 waiting predictions.
Run a continuous-review (Q,R) policy against steady demand and lead time, tracking shelves, inbound orders and backorders.
Balance annual ordering and holding cost on a cost beam and compare your chosen lot size with the continuous optimum Q*.
Compare pull and push release in a compact assembly cell through a customer pause and watch finished stock and backlog respond.
Circulate numbered kanban cards and containers through consumption, return, refill and delivery and see what the card count controls.
Compare a long-reach bench with point-of-use placement, follow the hand path and convert observed time to normal and standard time.
Plot subgroup means of machined shafts against three-sigma limits and tell a process signal from an out-of-specification part.
Compare three arrangements of six process stations and measure weighted travel, mean trip distance and transport workload.
