There are potential eco-efficiency benefits from ‘closing the loop’ in product life cycles. However, its implementation is not always straightforward especially for manufacturers of complex products such as electronic devices. They need to know how, where and when to close the loop in order to achieve the desired improvement in eco-efficiency. To help them do this, we propose a methodology that is...
This paper applies methods of fuzzy mathematics to set up the fuzzy comprehensive evaluation model for evaluation of enterprise culture. It provides a scientific and practical quantitative method for systematic analysis and comprehensive evaluation of enterprise culture of merged and acquired enterprises after their cultural integration.
Reuse of resources should be considered in the design stage to improve the efficiency due to the implementation of reverse logistics management by the enterprises. The keys for manufacturing companies to carry out reverse logistics are extended producer responsibility and lifecycle-oriented design. And cycle-logistics system which combines forward logistics and reverse logistics will be the trend...
In this work, approaches to improve current efficiency of white organic light-emitting diodes (WOLEDs) with high color purity have been studied. The emission layer in devices consists of 2-(t-butyl)-9,10-bis(2'-naphthyl)anthracene (TBADN) blue host and 5,6,11,12-tetraphenylnaphthacene (rubrene) yellow dopant. The efficiency can be enhanced by using architecture of dual emission layers and hole-blocking...
