In scheduling a large number of user jobs for parallel execution on an open-resource grid system, the jobs are subject to system failures or delays caused by infected hardware, software vulnerability, and distrusted security policy. This paper models the risk and insecure conditions in grid job...

RFID emerges to be one of the key technologies to modernize Logistics and supply chain management. In a typical RFID enabled logistics and supply chain application, there exist RFID readers to detect and identify the goods with RFID tags attached. Considering the huge amount of goods, the...

The "Grid", an initiative of the distributed computing community, offers unprecedented levels of computing power for organisations to apply to solving their business problems. Uniquely it also offers the communications infrastructure required to overcome the "tyranny of distance" observed by...

This paper reports a UK Economic and Social Research Council project that is exploring the use of Grid technologies to manage distributed data and act as a secure infrastructure for the delivery of computing power to distributed teams. The application focus used to test this infrastructure is...

The PERFORMS self-assessment scheme measures individuals skills in identifying key mammographic features on setsof known cases. One aspect of this is that it allows radiologists’ skills to be trained, based on their data from this scheme.Consequently, a new strategy is introduced to provide...

Economic scheduling needs to be considered for Grid computing environment, because it gives an incentive for resource providers to supply their resources. Moreover, it enforces efficient use of resources, because the users have to pay for theiruse. Tendering is a suitable model for Grid...

Mit zunehmender Verbreitung von Grid-Infrastrukturen in Unternehmen gewinnt die Frage nach Vertrauen immer mehr an Bedeutung. In einer offenen, heterogenen, sich st?ndig ver?ndernden Umgebung, wie z.B. der Grid-?konomie ist hundertprozentige Sicherheit nicht zu gew?hrleisten; aus diesem Grund...

As Grid computing commenced in the scientific sector, it slowly enters the commercial environment. Although it proposes interesting features for horizontal integration of hardware and resource sharing, businesses slowly implement Intragrids in their companies. Open Grid markets are yet not deployed.

This work is concerned with the conduct of MCDM by intelligent agents trading commodities in ALNs. These agents consider trustworthiness in their course of negotiation and select offers with respect to product price and seller reputation.

Any major research institution has a substantial number of computer systems on its campus, often in the scale of tens of thousands. Given that a large amount of scientific computing is appropriate for execution in an opportunistic environment, a campus grid is an inexpensive way to build a...
