Simulation resources: papers, talks and the tour
Read our articles and published papers, walk through past models, watch a talk, or pick up a book by one of our founders.
Insights
Short articles on the questions we get asked most: buffer sizes, run lengths, safety stock, moving bottlenecks and when to model by rate.
Read the articlesPapers
Winter Simulation Conference papers by SDI authors since 1995 on bulk flow and discrete rate simulation, plus related research by others.
Browse the papersSelf-guided tour
Our work sorted into four areas: manufacturing, supply chain, logistics and resource management, with model screens and plots.
Take the tourCase studies
Twenty projects, each with the question, the model and what the client did with the answer.

How data-based simulations find the fastest wins
A 2025 talk: "How Data-Based Simulations Find the Fastest Wins and Best Options for Optimization."
Essay, 2003
Why supply chain management matters
Hidden safety stock on both sides of a pipeline, orders that sit for days waiting for someone's planning cycle, and a truckload policy that creates the variability it insures against. Our 2003 essay, still cited.

Tell us your problem
What would happen if you changed it?
Describe the decision in front of you. We'll tell you whether a model can answer it, and what it would take.
- A straight answer on whether simulation is the right tool
- Which tool fits, even if it isn't one we use every day
- A rough scope and timeline, before any commitment
