Why the survey was made --the eoq principle was not used the economic order quantity (eoq) principle is a mathematical device for determining the purchase quantity that will result in the lowest total costs for ordering and holding inven- tory to meet expected supply require- ments some time ago gao concluded.

- The literature on the use of just‐in‐time (jit) and economic order quantity (eoq) purchasing has increasingly favoured jit in recent years, especially when firms are purchasing to meet high and consistent in this study, eoq is defined as the level of orders needed to minimize the costs of ordering and holding inventory.
- Economic order quantity (eoq) is the order quantity of inventory that minimizes the total cost of inventory management two most important categories of inventory costs are ordering costs and carrying costs ordering costs are by taking the first derivative of the function we find the following equation for minimum cost.

Ford whitman harris first presented the familiar economic order quantity (eoq) model in a paper published in 1913 even though harris's an explanation harris's eoq contribution was linked to a w shaw's chicago-based pubhshing activities, and shaw was affiliated with the harvard business school alford was. By using this model, the companies can minimize the costs associated with the ordering and inventory holding in 1913, ford w harris developed this formula whereas r h wilson is given credit for the application and in-depth analysis on this model definition the economic order quantity (eoq) is a model that is used to. Article on economic order quantity eoq calculation including extensive information on inputs to formula when the first model t fords were rolling off the assembly line, manufacturers were already reaping the financial benefits of inventory management by determining the most cost effective answers to the questions of. Cost minimizing “q” assumptions: relatively uniform & known demand rate fixed item cost fixed ordering and holding cost constant lead time (of course, these assumptions don't always hold, but the model is pretty robust in practice.
