A conventional approach for solving an economic production quantity (EPQ) model with multi-delivery policy and quality assurance is to use mathematical modeling for deriving the system cost function and to employ differential calculus for proving convexity of the cost function before determining the optimal operating policy. This paper presents a simplified solution procedure to reexamine a specific EPQ model [1] and demonstrates that both, the optimal manufacturing lot size and the long-run cost function can be derived without derivatives. The proposed approach may enable practitioners-with little knowledge of calculus-to understand such a real life vendor-buyer integrated system with ease.
