Such a system is not only agile and accurate, it besides provides management with continuously updated information on the status of inventory levels. many manufacturing companies ’ suppliers and distributors besides use bar code systems and handheld laser scanners to armory materials, supplies, equipment, in-process parts, and finished goods .
Periodic Review System (P)

You place an decree for an amount ( Q ) equal to the target inventory tied ( TI ), minus the quantity on hand ( OH ), alike to the min-max system. The deviation is that with the periodic review system, the time between orders is constant ( such as every hour, every day, every week, or every calendar month ) with varying quantities ordered. The min-max system varies both the time between orders and the quantities ordered .
