What is replenishment system?
A replenishment system is a process of maintaining inventory levels to ensure that products are available for customers who want to purchase. There are two types of replenishment methods that are manual and automatic. This method involves to track inventory levels, forecast demand, and reorder products when necessary.The manual component of a replenishment system involves regular physical checks of inventory levels to determine when products need to be restocked or stop the dispatch. This process can be done on the basic regular schedule like daily/weekly/monthly, or triggered by specific events like suddenly increase in demand due to occasion/festival or new assortment of products arrival. This process seems slow and more error-prone, but it can be a good choice for smaller businesses or those who have low inventory turnover rates. Some businesses may prefer a manual system because they want more control over their inventory management process..
The automatic component of a replenishment system uses software including a certain set of rules like reorder level, economic order quantity, min/max, and lot size to monitor inventory levels and generate automatic purchase orders when inventory falls below a certain threshold. This automatic process can help to reduce the risk of stockouts and ensure that products are always available for customers who want to purchase..
Overall, a replenishment system is a process that can help businesses to manage inventory levels more efficiently, reduce cases of stockout and overstocking, and improve customer satisfaction by ensuring that products are always in stock and available for purchase.

Most common method of automatic replenishment systems used in inventory management:
1. Min/Max: This system involves setting a minimum and maximum inventory level for a given product, and automatically triggering a replenishment order when the inventory falls below the minimum threshold.
Formula: Reorder point = Max - (Current Inventory Level + On Order - Safety Stock).
Example: A hardware store sets a min/max inventory level of 10-50 for a particular type of drill. When the inventory level falls to 10, the system automatically triggers a replenishment order to bring the inventory level back up to 50.
2. Reorder Level: This system involves setting a specific reorder level for a given product, and automatically triggering a replenishment order when the inventory falls below that level.
Formula: Reorder point = Lead time demand + Safety stock.
Example: A grocery store sets a reorder level of 50 for a particular brand of cereal. When the inventory falls below 50, the system automatically triggers a replenishment order to bring the inventory level back up to the reorder level.
3. Economic Order Quantity (EOQ): This system calculates the optimal order quantity for a given product based on factors such as demand, lead time, and order costs.
Formula: EOQ = sqrt(2DS/H), where D is the annual demand, S is the order cost, and H is the holding cost.
Example: A clothing store uses the EOQ system to determine the optimal order quantity for a particular style of t-shirt. Based on their data, they determine that the annual demand is 10,000, the order cost is $50, and the holding cost is $0.50 per shirt. Using the formula, they determine that the optimal order quantity is 447.
4. Minimum Based Quantity (MBQ): This system determines the minimum amount of stock that needs to be maintained to meet the demand for a particular product.
Formula: MBQ = (Demand per unit of time x Lead time) + Safety stock.
Example: let's say a company sells a particular product that has a demand of 100 units per month. The lead time for ordering and receiving inventory is two weeks, and the company wants to maintain a safety stock of 50 units to ensure that they have enough inventory to meet unexpected demand and MBQ is 200 units.
5. Current Sale: This system involves automatically triggering a replenishment order based on the current sales data for a particular product. This system takes into account the rate at which the product is selling, as well as the expected rate of sales in the near future.
Formula: Reorder point = Sales rate x Lead time.
Example: A grocery store uses the current sale system to automatically trigger a replenishment order for a particular type of fruit based on the current sales data. If the fruit is selling faster than expected, the system will trigger a replenishment order to ensure that the store has enough inventory to meet customer demand.
6. Sales Cover: This system involves setting a target number of days that a particular product should be in stock, and automatically triggering a replenishment order when the inventory falls below the target level.
Formula: Sales cover = (Current Inventory Level + On Order) / Average daily sales.
Example: A fashion retailer sets a sales cover target of 30 days for a particular style of dress. If the current inventory level plus any inventory on order is not enough to cover 30 days of sales, the system will trigger a replenishment order to bring the inventory level up to the target level.
Formula: MBQ = (Demand per unit of time x Lead time) + Safety stock.
Example: let's say a company sells a particular product that has a demand of 100 units per month. The lead time for ordering and receiving inventory is two weeks, and the company wants to maintain a safety stock of 50 units to ensure that they have enough inventory to meet unexpected demand and MBQ is 200 units.
5. Current Sale: This system involves automatically triggering a replenishment order based on the current sales data for a particular product. This system takes into account the rate at which the product is selling, as well as the expected rate of sales in the near future.
Formula: Reorder point = Sales rate x Lead time.
Example: A grocery store uses the current sale system to automatically trigger a replenishment order for a particular type of fruit based on the current sales data. If the fruit is selling faster than expected, the system will trigger a replenishment order to ensure that the store has enough inventory to meet customer demand.
6. Sales Cover: This system involves setting a target number of days that a particular product should be in stock, and automatically triggering a replenishment order when the inventory falls below the target level.
Formula: Sales cover = (Current Inventory Level + On Order) / Average daily sales.
Example: A fashion retailer sets a sales cover target of 30 days for a particular style of dress. If the current inventory level plus any inventory on order is not enough to cover 30 days of sales, the system will trigger a replenishment order to bring the inventory level up to the target level.
7. Top-Off: This system involves automatically triggering a replenishment order whenever the inventory level falls below a predetermined threshold, regardless of the order quantity.
Example: A bookstore uses the top-off system to automatically trigger a replenishment order for a popular book whenever the inventory level falls below 5 copies.
8. Periodic: This system involves automatically triggering a replenishment order on a regular, pre-determined schedule, regardless of inventory levels.
Example: A pet supply store uses the periodic system to automatically trigger a replenishment order for dog food every two weeks, regardless of inventory levels.
