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...

INTRODUCTION Metal scrap is a widely used material in steel production, with international trade amounting to about 40 million tons a year. As Italy has no iron production worth mentioning from mines, the country is the first importer of metal scrap in the European Union. The Italian Association of traders of iron and steel, non-iron metals, iron scrap, iron-mongery and similar products (ASSOFE...

In the present paper we investigate a EOQ model for imperfect items under time variable linear demand. The defective items is being screened out by a 100 % screening process and then sold in a single batch by the end of the 100% screening process with a salvage price. The unsold perfect item during the cycle is sold at a different salvage price at the end of cycle. Two different types for cost ...

Experiments were conducted to demonstrate the utility of a rule-plus-exception model for extending current exemplar-based views of categorization and recognition memory. According to the model, exemplars that are exceptions to category rules have a special status in memory relative to other old items. In each of 4 experiments, participants first learned to categorize items organized into 2 ill-...

Recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver...
