CHIU, Y.-S.P.; WU, M.-F.; CHIU, S.W.  e  CHANG, H.-H.. A simplified approach to the multi-item economic production quantity model with scrap, rework, and multi-delivery. J. appl. res. technol [online]. 2015, vol.13, n.4, pp.472-476. ISSN 2448-6736.  https://doi.org/10.1016/j.jart.2015.09.004.

In a recent paper, Chiu et al. (2014) utilized mathematical modeling and differential calculus to determine the common production cycle time that minimizes total production, inventory, and delivery costs for a multi-item economic production quantity (EPQ) model with scrap, rework, and multi-delivery. The present study proposes an algebraic approach substituting the use of differential calculus on the system cost function for deriving the optimal common cycle time in the aforementioned multi-item EPQ model. This simplified approach may enable managing practitioners to resolve real multi-item EPQ models more effectively.
