In a grid computing environment, it is important to be capable of agilely quantifying the quality of service achievable by each alternative composition of resources. This capability is an essential driver to not only efficiently utilizing the resources but also promoting the virtual economy. In this paper, we design an efficient scheduling algorithm of minimizing completion time for component-b...

Much of the radical transformation of the world economy from an industrial, manufacturing-oriented economy to a post-industrial, service-oriented one comes from the application of information technology (IT) to service delivery (Rai and Sambamurthy 2006). IT has contributed – and continues to contribute – to increased efficiency and effectiveness in service delivery. ITalso reduces the cost of ...

This paper proposes and describes a new method that can be used to schedule individual traffic flows, which share a common channel and have been shaped/policed by means of a Token Bucket (TB) mechanism. The method can also be extended to dynamically allocate bandwidth to this channel, based on information derived from TB states. Simulation results are presented and discussed.

The virtual economy operates like the one in the physical world, which is realized by players with two functions–demand and supply, only using the form as avatars. Only that in virtual worlds, the prices of virtual items is decided by the players instead of by its quality or scarcity, so the player behavior analyses became an important tool to monitor the persistent virtual worlds. In order to ...

A final report of RISE: RTOs in the service economy-Knowledge infrastructures, innovation intermediaries and institutional change RISE reports may be downloaded from:

Services have been regarded as something intangible, perishable, and heterogeneous so that it is difficult to measure the quality and productivity of them. Services also have long been considered non-productive economic activities. However, considering the recent growth of service industry across the world, it is imperative to study the very nature of service and its systems in the knowledge-ba...
