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...

Several researchers have recently derived formulae for economic order quantities (EOQs) with some variants without reference to the use of derivatives, neither for first-order necessary conditions nor for second-order sufficient conditions. In addition, this algebraic derivation immediately produces an individual formula for evaluating the minimum expected total annual cost. The purpose of this...

a r t i c l e i n f o This paper expands an inventory model for deteriorating items with stock-dependent demand. This model provides time varying backlogging rate as well as time varying deterioration rate. The aim of this model is to determine the optimal cycle length of each product such that the expected total cost (holding, shortage, ordering, deterioration and opportunity cost) is minimize...

Business organizations that deal with consumable and perishable items have consistently incurred enormous loss as a result of the nature their goods. The losses direct negative impact on revenues. Unplanned lack precise production prediction models are responsible for this. An appropriate model, developed to guide plan processes will help manufacturers in deciding which product make what quanti...

It was suggested in 2004 by some researchers that it might be possible to improve production systems performance by applying the first and second laws of thermodynamics to reduce system entropy. Then these laws were used to modify the economic order quantity (EOQ) model to derive an equivalent entropic order quantity (EnOQ). Moreover the political instability or uncertainty of a country (as wel...

Lack of purchasing planning and proper demand forecasting causes hospitals to suffer from drug inventory mismatches with actual demand; in other words, the management cost is high if quantity exceeds or less demand. Therefore, this research aimed plan an appropriate purchase reduce costs effectively meet hospital's pharmaceutical needs a case study: i) for 29 AV drugs using Minitab 19, ii) econ...
