Summary
👤
Senior🎓
Top SchoolKlaas Krutein is an Applied Scientist II in Seattle with 8 years of experience applying operations research, stochastic optimization, and simulation to large-scale logistics and supply chain problems. He has driven measurable impact across industry and research—from cutting middle-mile resource planning costs at Amazon to leading production routing systems at Convoy that delivered a 7.1% cost reduction and a 21.6% drop in scheduling losses. His work blends rigorous academic training (PhD/MS in Industrial Engineering from the University of Washington) with practical productionization skills, including harmonizing modular routing machines and deploying an LLM-based chatbot to reduce support load. Currently he leads simulation and explainability for tactical supply chain decisions in Devices Supply Chain, focusing on short- and long-term decision dynamics under uncertainty. Klaas’s background in evacuation modeling and urban freight research reveals a knack for translating complex mixed-integer and stochastic models into concrete time-savings and infrastructure improvements.
