Inventory models play a leading role in analyzing a lot of realistic situations arising at places like, food and vegetable markets, market yards, oil exploration industries, etc. In the present article, we developed an inventory model for deteriorating items with permissible delay in payment under inflation. In the given model, demand rate is considered as stock-dependent and deterioration rate...

this study considers an eoq inventory model with advance payment policy in a fuzzy situation by employing two types of fuzzy numbers that are trapezoidal and triangular. two fuzzy models are developed here. in the first model the cost parameters are fuzzified, but the demand rate is treated as crisp constant. in the second model, the demand rate is fuzzified but the cost parameters are treated ...

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...

The main objective of this paper is to develop a Supply chain model of a volume agile manufacturing process for the deteriorating items. It is assumed that an EOQ model in which inventory is depleted not only by demand also by deterioration. In this study, a model for the producer by assuming stock dependent demand rate is developed. It is assumed that the deterioration rate follows the Weibull...

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...

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.
