Try an ordering decision, test a forecast, or compare inventory policies. Each activity gives you a different way to work through a supply chain problem.
Explore decisions, uncertainty, and trade-offs with reproducible experiments.
Follow named customer relationships across S&P 500 firms. Switch between a network and a headquarters globe, and inspect each filing.
● LiveExplore the map →Compare optimal Wagner–Whitin schedules with lot-for-lot and Silver–Meal. Inspect orders, inventory and the cost of each decision.
● LiveOpen lab →Compare regional and centralized safety stock. Explore how demand correlation and lead time change potential inventory savings.
● LiveOpen lab →Compare inventory policies under uncertain demand and delivery delays across 100 shared scenarios.
● LiveOpen lab →Test forecasts on unseen periods and compare accuracy with the cost of shortages and surplus.

Watch how a small change in consumer demand gets amplified upstream. Adjust lead times, safety stock, and smoothing to explore the bullwhip effect interactively.
● Live Play Now →Explore the Economic Order Quantity model interactively. Adjust demand, holding costs, and ordering costs — watch the total cost curve update in real time, then test your skills in quiz mode.
● Live Play Now →Apply Moving Average, Exponential Smoothing, and Linear Trend methods to real demand patterns. Pick the best method for each scenario and minimize forecast error.
● Live Play Now →Experience panic buying in a supply chain. Decide how much to order when news events hit — watch how individual rational decisions create collective chaos through the bullwhip effect.
● Live Play Now →Evaluate suppliers using weighted scorecards across price, quality, reliability, stability, and sustainability. Learn why the cheapest option isn't always the best.
● Live Play Now →Source from global suppliers while carbon prices rise each round. Optimize for both cost and emissions — watch how carbon pricing reshapes sourcing strategy.
● Live Play Now →Set optimal order quantities under demand uncertainty. Balance overage and underage costs to maximize profit in a single-period inventory setting.
● Live Play Now →Set the right safety stock level for each product-demand scenario. Too much costs money, too little means stockouts — find the sweet spot.
● Live Play Now →Match supply chain strategies (lean, agile, leagile) to business scenarios. Test your understanding of when each approach works best.
● Live Play Now →Sort items by annual usage value, then decide which ones need the closest inventory control.
● Live Play Now →Estimate total lead times across multi-tier supply chains. Account for processing, transit, customs, and variability at each stage.
● Live Play Now →Longer games where each round's decision changes the one after it. Every scenario is deterministic, so two people who make the same calls get the same result and can compare them line by line.
Three plants, eight rounds, one growing market. The cheapest plant takes three rounds to build a line and two more to ship what it makes — so you commit capacity against a forecast and are graded against what actually happened.
● Live Play Now →Five delivery days over one territory. You size the fleet and cluster the stops; the model sequences each vehicle and prices the day against capacity, time windows and the length of the shift.
● Live Play Now →Five suppliers whose quotes span four dollars a unit and whose landed costs span about one. Eight quarters to work out which gap is real, while the exchange rate moves and a duty rate changes.
● Live Play Now →Ten weeks of a supply crisis and six ways to respond. The cheap levers need notice you do not have; the fast ones are capped. Doing nothing and doing everything are both computed, and neither is right.
● Live Play Now →Multiplayer simulations — requires login and an instructor-hosted session.
Experience the bullwhip effect firsthand. Manage a 4-tier supply chain as retailer, wholesaler, distributor, or factory — and see how small demand changes amplify upstream.
