The EOQ and EPQ models with linear and fixed backorder costs are newly analyzed and all formulae are proven using only algebra. Two cases are identified, where backorders should and should not be allowed. The results are shown to include several known special cases. r 2004 Elsevier B.V. All rights reserved.

Inventory management is the core of supply chain system, in which economic order quantity (EOQ) model a fundamental inventory model. This paper develops fuzzy EOQ presence inspection errors single sampling plans. The assumes probability mis-classifications. An system hypothesized where orders undergo acceptance sampling, back-orders are eliminated, and defectives set aside from inventory. Due t...

The algebraic arithmetic-geometric mean inequality method (the algebraic AGM method) is used to derive the optimal lot size and the optimal backorders level for the EOQ and EPQ models with backorders and defective items introduced by [6]. The method is easy to derive both the optimal lot size and optimal backorders level without derivatives. AMS Subject Classification: 90B05

UMKM Hoki Tahu adalah industri yang bergerak dalam pembuatan tahu dengan bahan baku kedelai. Bahan kedelai memegang peranan penting kegiatan produksi sehingga pengendalian stock harus dikontrol baik supaya tidak adanya kekurangan atau penumpukan terlalu lama menimbulkan pemborosan biaya. Saat ini, menggunakan metode Aktual, peneliti mencoba membandingkan EOQ, POQ, dan Min – Max selama tahun 201...
