Reference work entry

A batch is a quantity either in production or scheduled to be produced. The concept of batch size is best defined in terms of two different concepts, the process batch and the transfer batch. A process batch is the quantity of a product processed at a work center before that work center is reset to produce a different product. A transfer batch is the quantity of units that move from one work center to the next. The transfer batch size need not, and in most cases, should not be equal to the process batch size; process batch can be equal or grater than transfer batch. In synchronized or lean manufacturing systems, the transfer batch size generally should be kept as small as possible in order to ensure a smooth and rapid flow of materials. The process batch size should be determined by the requirements of the system and should be allowed to be variable as needed over time. At bottleneck work centers, especially those with significant setup times, the small transfer batches should be used...
