Secondly, many products have seasonal demand, where sales will rise and fall at certain times of the year. For example, products in the growth stage will see demand increase over time, whilst those at the end of maturity and facing decline will tend to see demand get lumpier and more inconsistent before it drops off. Firstly, as items move through their product lifecycle their demand will change. Using the EOQ model would be relatively simple for a business that has consistent demand for each inventory item throughout the year – but this is often not the case. Here are some key problems: How do you deal with demand fluctuations? But, in reality there are many limitations to this over-simplistic framework. Many inventory planners think that finding the right EOQ for each item they stock will help them achieve lower inventory costs. Limitations of the Economic Order Quantity (EOQ) model

Our blog post on how to calculate economic order quantity gives you a working example of how to use the formula. The economic order quantity will identify when both of these costs are at their lowest.
But, at the same time, the more items you hold at one time in your warehouse, the higher your carrying costs will be.
The EOQ model is used by inventory planners to work out the most ‘cost effective’ amount of stock to reorder.Įconomies of scale states that the more goods you procure in one order, the lower the ordering cost per unit. The Economic Order Quantity (EOQ) is the ideal quantity at which inventory carrying costs and ordering costs are both at their lowest. In this post we take a closer look at the economic order quantity model and its limitations. However, EOQ is often criticised for being over-simplistic and relying on consistent data inputs which don’t really reflect reality. The economic order quantity (EOQ) model is a fairly popular means of calculating inventory reorder quantities and working out how many orders to place per annum.
