基于混合遗传的粗集理论在工期目标实现中的应用

提出了一种基于混合遗传算法的相对约简算法,把模拟退火融入到遗传算法中形成混合遗传算法,提高了遗传算法的优化效率,并用这种混合遗传算法寻求最小条件属性集及最小属性值约简.并把该算法引入到工程管理中,提出若干条决策规则,工程管理人员按照这种决策规则进行施工过程的管理,确保在预定时间内完成工程任务.如果对整个施工过程的每道工序都提出决策规则,就可以实现施工过程的智能化管理.

Apply of the Rough Set Theory on the Basis of the Hybrid Genetic Algorithm in the Subject of the Engineering Period

A kind of relative reduction algorithm based on hybrid genetic algorithm was proposed. Genetic Algorithm combining with Simulated Annealing produces HGA in order to improve performance of GA. And the HGA is utilized to search of minimum condition attributes and their values. The algorithm is introduced into construction management so some decision rules can be extracted. Construction managers ensure to finish expected task in provided period according to the decision rules. The whole construction process will be managed by brainpower if every activity has its own decision rules.
