Abstract: As resource allocation becomes a main problem in grid computing area，at present，research of some computational intelligence method forces on solving resource allocation of grid environment，but the resource on enhancing the efficiency of resource allocation on condition of mixed methods is not very abundant.In this paper，a hybrid search algorithm with heuristics for resource allocation problem is proposed.Searching in the resource through genetic algorithm with heuristics，making a further explore in generated results by making use of ant colony algorithm.The result of the simulation shows that the proposed algorithm can effectively improve grid resource utilization rate.

摘要： 资源分配是网格计算研究领域中的一个要点问题，目前已研究的若干计算智能方法大多是单一的用于解决网格资源分配问题，对于在混合的前提下提高资源分配性能方面还缺乏深入的研究。为此，针对网格资源分配问题提出了一个启发式混合搜索算法，通过带有启发式的遗传算法在资源中进行搜索，在生成的解中再利用蚁群算法做进一步的探索。仿真实验结果表明，该算法在满足用户需求的前提下，有效地提高了网格资源利用率。
