Abstract: Grid service scheduling algorithms are kernel technictue in task management system of computing grid. Using a grid service deployment agent technology based on the fuzzy-PID feedback control model, a new grid service deployment agent technology was put forward for solving the uncertainty in task scheduling of the computing grid. This method fuses the fuzzy theories and PID technology. Theory analysis and numerical experiment illustrate that this method can express the dynamics and uncertainty of expected time to compute of tasks and bring the dummy executing competence into play in the computing grid environment, they are the generalization of traditional grid scheduling algorithms.At the same time, it can afford the balanced bandwidth, delay and reliability.
