The reorder point (ROP), also reorder level (ROL) or "optimal re-order level", [1] is the level of inventory which triggers an action to replenish that particular inventory. It is a minimum amount of an item which a firm holds in stock, such that, when stock falls to this amount, the item must be reordered.
If there are backorders, the reorder point is: =; with m being the largest integer and μ the lead time demand. Additionally, the economic order interval [ 8 ] can be determined from the EOQ and the economic production quantity model (which determines the optimal production quantity) can be determined in a similar fashion.
Material requirements planning (MRP) is a production planning, scheduling, and inventory control system used to manage manufacturing processes. Most MRP systems are software-based, but it is possible to conduct MRP by hand as well.
When a product is in a warehouse or store, it can be tracked via its barcode and/or other tracking criteria, such as serial number, lot number or revision number.Systems for Business, Encyclopedia of Business, 2nd ed. Nowadays, inventory management software often utilizes barcode, radio-frequency identification (RFID), and/or wireless tracking technology.
Reorder level: Reorder level refers to the point when a company place an order to re-fill the stocks. Reorder point depends on the inventory policy of a company. Some companies place orders when the inventory level is lower than a certain quantity. Some companies place orders periodically.
The precedent theorems are used in the proof of the Planning Horizon Theorem. [1] Let = [< [+ = = + + ()] + ()]denote the minimal cost program for periods 1 to t. If at period t* the minimum in F(t) occurs for j = t** ≤ t*, then in periods t > t* it is sufficient to consider only t** ≤ j ≤ t.
Material theory (or more formally the mathematical theory of inventory and production) is the sub-specialty within operations research and operations management that is concerned with the design of production/inventory systems to minimize costs: it studies the decisions faced by firms and the military in connection with manufacturing, warehousing, supply chains, spare part allocation and so on ...
