There is a slew of courses taught on inventory and supply chain management as a subset of industrial engineering, and there are also schools that teach both disciplines alone. Managing inventory is a large part of both, and you can discuss things like the bullwhip effect, the formulas and principles behind economic order quantities (EOQ), and warehouse visuals and organization. The sky's the limit here, so pick an area of warehousing and/or logistics and discuss what you know about inventory management in these cases.
