Brawny Brackets: Connecting the dots from layout design to pull flow

Lean production (“Lean”) is a topic frequently taught in undergraduate and graduate operations/supply chain management courses. Lean's “pull system” is a common component of the instruction, and several useful simulations have been developed that allow students to experience a pull system firsthand. While existing simulations focus on the mechanics of a pull system, the Brawny Brackets simulation focuses on improving “flow”—that is, framing a pull system in the context of layout design and batch sizing, and the waste associated with jumbled flow patterns. The robust and flexible simulation allows instructors to expand or contract the topics taught to match the course objectives and teaching time available.

Brawny Brackets is a useful tool to help students learn how to improve operational efficiency and effectiveness. As this article demonstrates, the Brawny Brackets simulation can enhance student learning in operations and supply chain management courses in both undergraduate and graduate courses.
