If you use inventory (WIP) as a buffer and decide to be "lean" and limit the amount, what must you do first to maintain or increase throughput (TH). c. Refer to the FP "Process Batching Law," and the "Move Batching Law," and define the term "lot splitting." What are the tradeoffs in "lot splitting" in how you size each one in terms of WIP, conveyance devices, and material handling costs? d. If you reduce the "move" batch size, will the CT increase or decrease. Why? e. In general what happens to TH whenever more buffer space is added ahead of the bottleneck station
