See how systems of people, goods and money behave: queues that explode near capacity, stock that runs out, supply chains that whip, and markets that clear.
11 live simulators
Simulate customers arriving at random and being served by one or more servers, change arrival and service rates, and compare queue length and waiting time with M/M/c theory.
College & beyondCollege operations research
Launch simulator: Queueing Systems
Run a shop's stock day by day with random demand, set the reorder point, order quantity and lead time, and compare stockouts, holding cost and ordering cost.
College & beyondCollege operations management
Launch simulator: Inventory Control
Run a four-stage retailer–wholesaler–distributor–factory chain, change demand and delays, and watch small changes in consumer demand amplify into the bullwhip effect.
College & beyondCollege operations management
Launch simulator: Supply Chain
Simulate a serial production line, change station times, variability and buffer sizes, and find the bottleneck that sets throughput.
College & beyondCollege operations management
Launch simulator: Assembly Line
Time a fixed-cycle traffic signal at a two-phase junction, change green times and arrival rates, and compare measured queues and delay with Webster's formula.
College & beyondCollege transport engineering
Launch simulator: Traffic Signals
Run one lift in a ten-floor building, add calls by clicking floors, and compare first-come-first-served, nearest-stop-first and the classic sweep (elevator) algorithm on waiting time and fairness.
College & beyondCollege operations research
Launch simulator: Elevator Dispatch
Place items to pick in a six-aisle warehouse and compare the walking distance of return, S-shape, nearest-neighbour and optimal picking routes.
College & beyondCollege operations research
Launch simulator: Warehouse Picking
Edit task durations and dependencies in a small building project, and watch the critical path method find the project length, the critical path and every task's slack.
College & beyondCollege project management
Launch simulator: Project Scheduling
Enter hypothetical bidder values and bids, compare who wins and what they pay under first-price, second-price, English and Dutch auctions, and test revenue equivalence over many random auctions.
College & beyondCollege economics
Launch simulator: Auction Mechanisms
Shift linear supply and demand curves, add a tax, price ceiling, price floor or quota, and inspect the modelled equilibrium, consumer and producer surplus, and deadweight loss.

Follow 100 tonnes of packaging through collection, sorting and reprocessing, change collection, contamination, sorting accuracy and purity limits, and track how much becomes new material over repeated cycles.
