Optimization of a product batch quantity

Abstract

Companies encounter various challenges when entering the global market, one of the most significant being the calculation of the optimal batch quantity of a product. This paper explains how to calculate the optimal batch quantity using first the basic model, and then the extended model that takes into account the tied-up capital in a production, in addition to the costs of changing the batch and storage costs. There is a case study of calculating the optimal batch quantity using the basic and extended models, together with conclusions regarding when either of the two models should be used. For optimal batch quantities we also calculated lead times, corresponding costs of tied-up capital per piece, and the difference between costs per piece when using the basic and extended models. © 2014 Journal of Mechanical Engineering.
