Over recent years, the model-based parameter tuning of computational systems has become an emergent research topic. When the considered systems are subject of stochastic effects, the parameter tuning can be seen as a noisy optimization task, as often faced in production engineering. In this paper, the current research on parameter optimization is discussed based on experiences from an engineeri...

In this paper, greening, pricing, and advertising policies in a supply chain will be examined with government intervention. The supply chain has two members. First, a manufacturer seeking to determine the wholesale price and the greening level and second, a retailer that has to determine the advertising cost and the retail price. The government is trying to encourage the manufacturer to green t...

degradation of o,o-dimethyl -o-4-nitrophenylphosphorothioate (methylparathion) by ozonation in aqueous solution was studied in a batch reactor under constant ozone dosage and variable ph conditions. the effectiveness of the process was estimated based on the degree of cod (chemical oxygen demand) reduction and conversion of methylparathion. it was observed that ozonation is more effective at a...

the aim of this study was to represent effective componentsin demand chain which help organizations attain high performance levelsthrough identification of these components and determining theirdegree of importance. the following questions were major ideas of thisstudy: what are the most effective components in demand chain? andhow are they effective on organizational performance? to this end,m...

ABSTR ACT: Modern medicine faces a growing crisis as demand for organ transplantations continues to far outstrip supply. By stimulating the body’s own repair mechanisms, regenerative medicine aims to reduce demand for organs, while the closely related field of tissue engineering promises to deliver “off-the-self ” organs grown from patients’ own stem cells to improve supply. To deliver on these...
