Abstract
In this paper, we propose that stock-turn-over under the assumption of ordering point system is available as a measure of stratification between a group of the items in the production-to-order system and the other group of the items in the production-to-stock systam in the case that what items should be changed from the production-to-order system to the production-to-stock system in a factory where many items of catalogued product are manufactured under the production-to-order system.
