| 摘 要： | 为了提高耦合活动集割裂规划的有效性,针对现有割裂方法只考虑设计活动之间行为上依赖关系的局限性,提出基于互相关度和自相关度综合指标的割裂准则.在构造该准则的过程中,用三角模糊数的层次分析法(AHP)分析设计资源之间的关系;用互相关度指标分析设计活动与设计资源之间的关系;用自相关度指标分析设计活动之间的关系.最后,结合某型起重机改进设计的实例,对新的割裂准则进行说明和验证.实践表明,该方法能有效保证并行设计过程在资源约束条件下顺利进行,并为设计资源快速调度规划提供依据.

| Abstract: | To improve the effectiveness of tearing algorithm of coupled activity set,a new tearing criterion is presented in view of the disadvantages of the existing algorithms.In its construction process,the relations between two resources were analyzed by the analytic hierarchy process(AHP) method based on triangular fuzzy number,and the relations between resource and activity were analyzed through degree of cross-correlation.Then the relations between two activities were analyzed through degree of autocorrelation.... |

| Keywords: | coupled activity set tearing resource density degree of cross-correlation degree of autocorrelation |
