In view of the problem that resources utilization rate is not high and node load are imbalance in current cloud computing environment
this paper presents a heuristic hybrid method based on genetic algorithm for workflow scheduling.At first
the tasks are sorted by priority in this algorithm.Then
it merges Best-Fit method to make an optimal initial population
and apply crossover and mutation operations to achieve the best solution finally.This algorithm in the task completion time and load balancing rate and speedup is better than other algorithms.
