Research on the Resource Sharing Among Hierarchically Distributed Virtual Enterprises Based on Grid System

ABSTRACT

In the virtual manufacturing process based on grid technology, the user and resource provider share resource and service connected through different virtual enterprises. In order to realize the target, virtual enterprise manages the enterprises at its lower level, and then the hierarchically distributed environment is formed. The resource provider and virtual enterprise should achieve the agreement on the strategy of resource sharing, such as the quantity, type and proportion of resource sharing. Therefore, the users in the virtual enterprises at lower level could get access to the resource of the upper level to achieve the common aim. The problem of allocating resources among hierarchically distributed virtual enterprises is the focus, and at the same time, suitable proportion of sharing resource is also discussed. In addition, under specific proportion condition, a new resource sharing scheme is put forward. Compared with some other resource sharing methods, the effectiveness of sharing resource is verified by using simulation software. The most effective and suitable resource sharing method among hierarchically distributed enterprises is explored.
