Inventory levels refer to the number of raw materials and components that are needed to produce the desired quantity of cars (1). Lead time refers to the amount of time required from when material is ordered until it arrives at its destination(2). Batch size is defined as the maximum number of units that can be produced by a certain manufacturing process before switching production over to another model or component (3).
