Economic lot size

The same principles used for developing an optimum design can be applied when determining the most favorable conditions in the operation of a manufacturing plant. One of the most important variables in any plant operation is the amount of product produced per unit of time. The production rate depends on many factors, such as the number of hours in operation per day, per week, or per month the load placed on the equipment and the sales market available. From an analysis of the costs involved under different situations and consideration of other factors affecting the particular plant, it is possible to determine an optimum rate of production or a so-called economic lot size.

Detailed inventory plans and shipping schedules can be developed, taking into account forecast of demand, economic lot size and planned production capacity. These are all correlated to financial advice on costs, and a model is utilized to project the cause and effect if any of these particular items are radically modified.

To fill its pipeline, TLC also purchased several containers of furniture, committing to a large inventory without firm customer orders. The manufacturers considered 20- or 40-foot containers an "economic lot size" for efficient transportation. However, TLC sales in the early stages were less than a container a month, leading to low inventory turnover.
