I can’t think of any online courses but last semester I took OTM 722 – Logistics Management. Its course description is “A foundation in transportation, order fulfillment, warehousing, materials planning including MRP, demand planning, import/export fundamentals, ERP systems, supply chain metrics, and leading supply chain technologies such as RFID.” It was a great class and I highly recommend it. I took it with Peter B. Lukszys and he’s a great professor. Also enrolled in OTM 727 – Enterprise Systems and Supply Chain Management with him this semester and I would also recommend that course.
