Reference work entry

When a component or product is produced in a factory, the production run normally refers to the batch size or quantity of a specific component or product produced before resetting the machine to make a batch of a different product. Every production run normally requires a variety of setup activities such as equipment preparation, cleaning, adjusting, and tools and fixtures change. Therefore, every production run normally has some associated setup time and setup costs. A production run size that is supposed to minimize all relevant costs including carrying costs and setup costs may be determined by various formulas to compute an economic run quantity. Some contemporary production systems, such as kanban or drum-buffer-rope systems, require that the production run size should be variable and determined by the requirements of the overall system.
