Towards Trustworthy Resource Selection in Grid: A Fuzzy Partial Ordering based Approach

The problem of resource selection in Grid is challenging because of the wide range of selection and the high degree of strangeness. Efficient resource sharing and utilization cannot be achieved without the guarantee of a higher degree of trust relationship. In this paper, reputation mechanism is introduced to resource selection in Grid, which aims at leverage the guarantee of trustworthiness and reliability. According to the fact that reputation is multi-faceted and uncertain, guided by the evaluation and decision making ideas from fuzzy partial ordering, the proposed approach makes fuzzy partial order modeling on each resource provider's multi-faceted reputation, integrates overall information, and choose proper resource providers according to the final integrative order. Compared with other methods, this approach has better overall consideration.
