The assumption of constant demand is consistent with the assumptions underlying the EOQ formula. If suppliers take some time to provide goods, orders need to be placed in advance of running out. Point A represents the cost at the order quantity indicated by the EOQ. If inventory is ordered in larger quantities, total costs will increase to point B1, at which stage bulk discounts are available, bringing the costs down to point B. Any calculations will involve finding which cost out of A, B or C is the lowest, as Example 1 will show. Coronavirus is certainly going to disrupt manufacturing and supply for many businesses.

For example, you cannot spend a budget on marketing campaigns to sell obsolete stock. In addition, you cannot use warehouse space efficiently and this can increase inventory costs. Referring to businesses that manage more than one facility across multiple locations. Businesses may operate several facilities for reasons such as expanding storage capacity, faster shipment of products to the end users by being closer to shipping facility, or stock occasional overstock with buffer warehouses. EOQ is the optimal level of inventory to purchase to meet customer demand. Having the perfect amount of stock on hand reduces storage, order and holding costs while eliminating unnecessary expenses.

Obsolete Inventory.

Inventory management allows for demand planning, and based on that information, businesses can determine reorder points and stock levels to avoid over or under-stocking products. Demand planning predicts the number of goods anticipated to sell so businesses can plan effectively to maintain sufficient inventory levels to satisfy that demand. It requires a variety of data sources, such as historical sales, customer trends, and seasonality data aiding organisations in making informed decisions about production, inventory management and resource allocation.

Also known as the Wilson formula, it determines the right amount of inventory stock to purchase at a given time. The EOQ formula can also be used to determine how many orders need to be made annually to satisfy demand. The supplier retains ownership of the products until they are sold, eliminating the need for business owners/retailers to bulk purchase the products upfront.

There are some pro-active solutions available to help manage die obsolescence, such as making project last-time-buys or use of long term storage/supply plans. Buffer inventory is simply the amount by which ROL exceeds average demand in lead-time. It is needed when there is uncertainty in lead-time demand to reduce the chance of running out of inventory and reduce the cost of such shortages. If orders are placed too soon, when there are still substantial supplies in inventory, then inventory levels and holding costs will be unnecessarily high. The re-order level as explained below should not be confused with the inventory control levels referred to in textbooks – this article ignores these. When it comes to calculating re-order levels, three sets of circumstances can be envisaged.

Intermittent demand: Linking forecasting to inventory obsolescence

Excess inventory ties-up capital, the cost of storing and managing and the added risk of the inventory becoming obsolete. Alternatively, shortages can lead to stockouts, loss of sales and delays in the customer purchase process leading to dissatisfied customers. Though inventory is recorded as a ‘current asset’ on the balance sheet, it consumes company capital. It ties up cash that can otherwise be redirected into other areas for growth or expansion.
