Abstract: A system and method of load balancing using fuzzy logic and, more particularly, to a system and method of load balancing tasks over a grid environment including, for example, CPU utilization, traffic over a network and other functions. The method comprises defining cause and effect relations associated with input variables and output variables. A current utilization is assessed. The method further includes determining which cause and effect relations are associated with the current utilization and calculating a weighted balancing factor for the cause and effect relations having membership with the utilization. A load is balanced using the weighted balancing factor.
