In this paper, the study attempts to determine the optimal capital investment in setup cost reduction and optimal lot sizing policies for an economic order quantity (EOQ) model with random yields. The setup cost is treated as the function of capital expenditure in technology. The study shows that the expected total annual cost functions with capital investment is convex and develop a solution p...

This paper develops an economic order quantity (EOQ) model with uncertain data. For modelling the uncertainty in real-world data, the exponents and coefficients in demand and cost functions are considered as interval data and then, the related model is designed. The proposed model maximises the profit and determines the price, marketing cost and lot sizing with the interval data. Since the mode...

We developed an economic order quantity (EOQ) model with a learning effect and carbon emissions under inflationary conditions inspection for retailers where the items deteriorate naturally. Finally, total profit of retailer is maximized respect to cycle length. A sensitivity analysis was also performed understand robustness model. In analysis, we discuss impact rate, inflation deterioration rat...

PT. Trijaya Tirta Dharma is an industrial company who produces products in form of the bottled drinking water. In several types water such as glass 150 mL and 240 mL, bottles 600 1500 final product gallon 19 L.
 Analysis cup material inventory control by using method EOQ to reduce production cost, especially cost materials infentory type tipe. Raw have a functions avoid shortage or excess....

This study aims to analyze and show how calculate EOQ prove that the use of method can make inventory costs efficient because number purchases is not excessive lacking, frequency exact time reordering. The theory underlying this research management, especially Single Item Method. analysis technique used descriptive using Optimalization , purchase (N), Reorder Point (ROP) results showed cost eff...

In this paper, we develop an economic order quantity (EOQ) model for fixed shelf-life items and a non-increasing demand. The objective of is to maximize the total profit. We find criterion decide (i) interior maximum solution or (ii) boundary solution. Eight numerical examples are given illustrate all possible scenarios generalized model. Our results identify scenario which profit always negati...

Raw material inventory is an important factor in supporting the company's production activities. purchase scheduling can increase productivity. When company faced with continuous demand, supplies control should be done optimally. This research aims to carry out of raw materials method Economic Order Quantity casing weaving Jenggolok hamlet, Gedangkulut Village Cerme-Gresik subdistrict. type qua...

Supplier selection and order allocation decisions are the main parties of a supply chain network which has high impact on economic performance this network. This study using an Economic Order Quantity (EOQ) concept proposes optimization model for integrated supplier problem where lot sizing, discounts, disruptions contributed among first studies in research area. To address uncertainty, scenari...

The study employed an innovative exercise-based instrument to identify individuals at risk for eating disorder (ED). The Exercise Orientation Questionnaire (EOQ), a reliable and valid instrument, was used to compare 80 ED patients, 74 obese patients, 99 elite runners, and 214 controls from a previous study. Runners resembled ED patients in scoring high on total EOQ and exercise intensity but di...

A new type of replenishment policy is suggested in an entropy order quantity model for a perishable product possessing fuzzy holding cost and fuzzy disposal cost. This model represents an appropriate combination of two component demand with discounted selling price, particularly over a finite time horizon. Its main aim lies in the need for an entropic cost of the cycle time is a key feature of ...
