Set packaging of battle storage spare parts was one way to realize unit packaging of battle storage spare parts and determinination of the variety and number of battle storage spare parts is the premise to realize set packaging. Aimed at the problem of determining the variety of meteorological and hydrological battle storage spare parts in set packaging, DHGF integrated algorithms was applied. The basic theory and structure of DHGF integrated algorithms was introduced. 9 evaluation index, such as vitality, availability, and relaiblity, were screemed from the aspects of importance, consuming, economy and packaging characteristic of spare parts. The evaluation model was constructed by using DHGF integrated algorithms. An example of power divider belonged to X-model wind profiler was given, and the last evaluation value was 7. 4241, which showed that application of DHGF integrated algorithms in spare parts set packaging is feasible and effective.
