The economic order quantity (EOQ) model is the simplest and earliest inventory model in the literature. Its simple mathematics is attributed to its assumptions, which are rarely met. Salameh and Jaber [2000. Economic production quantity model for items with imperfect quality. Int. J. Prod. Econ. 64, 59–64] addressed one of these assumptions that items received or produced are not of perfect qua...

 This paper presents an inventory model with non-instantaneous receipt under the condition of permissible delay in payments. Certain items like volatiles deteriorate during production process. In this paper, we consider deterioration into two phases i.e. phase 1 and phase 2. The purpose of this paper is to determine the optimal replenishment policies under conditions of non-instantaneous recei...

Penelitian ini bertujuan untuk menganalisis pengendalian persediaan obat pada Apotek XYZ sehingga pihak apotek dapat mengetahui secara efektif dan efisien. dilakukan dengan menghitung analisis metode ABC berdasarkan nilai pemakaian. Dari penelitian diketahui dari hasil pemakaian kelompok A terdiri 3 item atau 14,36% jumlah sebesar Rp. 88.090.000 58,89%. Kelompok B 4 19,39% 46.236.000 30,91%. C ...

The purpose of this paper is to develop a multi-item economic order quantity (EOQ) model with shortage for a single-buyer single-supplier supply chain under green vendor managed inventory (VMI) policy. This model explicitly includes the VMI contractual agreement between the vendor and the buyer such as warehouse capacity and delivery constraints, bounds for each order, and limits on the number ...

Available online 28 August 2014 In today's era of globalization, periodically new products with better value and added features are introduced into themarket. The rapid technological breakthroughs are creating significant risks of obsolescence at the product level. It creates enormous challenges to coordinate between technologymanagement and inventory control policies. Due to the dynamic nature...

Peranan sektor petanian di Indonesia sangat penting dalam perekonomian, terutama subsektor perkebunan. Salah satu perkebunan yang potensial dikembangkan Maluku adalah tanaman pala. Berdasarkan data rata-rata produksi pala Indonesia, merupakan salah sentra terbesar. Saat ini luas areal Pala sebesar 32.797 ha dengan sebanyak 5.859 ton. Hasil dapat menjadi peluang usaha baik lokal maupun antar neg...

We consider a continuous-review inventory model for a firm that faces deterministic demand but whose supplier experiences random disruptions. The supplier experiences “wet” and “dry” (operational and disrupted) periods whose durations are exponentially distributed. The firm follows an EOQ-like policy during wet periods but may not place orders during dry periods; any demands occurring during dr...

The purpose of this study is to find the optimal raw material inventory a company if it calculated using EOQ method. (case at Pt. Budi Strach & Sweetener, Tbk). data used in were taken from company's books and interviews with HRD personnel Tbk 2021. are: purchase data, usage frequency, cassava ordering storage cost data. analysis was carried out formula, safety stock, reorder point, total c...

Several authors have developed models for the EOQ when only a percentage of stockouts will be backordered. Most of these models are complicated, with equations unlike those for the EOQ with full backordering. In this paper we extend work by Pentico and Drake [The deterministic EOQ with partial backordering: a new approach. European Journal of Operational Research 2008; in press] that developed ...

This paper presents a simple algebraic approach for deriving the optimal lot size for economic production quantity (EPQ) model with rework process. Conventional methods for solving lot size problems are by using differential calculus on the long-run average production-inventory cost function with the need to prove optimality first. A few recent articles proposed the algebraic approach to the so...
