并行设计中耦合任务集割裂规划的新方法

耦合任务集的割裂规划有助于并行设计过程的组织管理，以加快设计过程收敛和减少产品开发时间。割裂规划方法研究旨在提高割裂规划的有效性。针对现有割裂规划方法的不足，本文提出了一套从构造到割裂数字双指标耦合任务集的系统化新方法：用敏感度与可变度双指标表征任务间依赖关系，用基于层次结构法的两两比较技术数字化双指标耦合任务集；用基于次序指标的算法割裂数字耦合任务集。最后，用汽车车门并行设计的实例对方法进行了验证。实践表明，该方法不仅能有效地保证并行设计过程的尽快收敛，而且具有一定的科学性系统民生，简单易用，具有实际的推广应用价值。

A New Tearing Method of Coupled Task Set within Concurrent Design Process

Tearing Algorithms of coupled task set is helpful in organizing and managing the concurrent design process to increase the efficiency of the design process and reduce the product development time. The study aim of the paper is to improve the effectiveness of tearing algorithms. In view of the disadvantages of the existing tearing algorithms, a new and systematic method is proposed. This new method measures the dependency between two tasks through sensibility and changeability, and numeralizes the bi-measure coupled task set based on a proposed pair-wise comparison technique of AHP method. And then, by defining a new concept of order index, a new algorithm to tearing coupled task set is provided. In the end of the paper, an auto door design case has been given to validate the new method, and the result shows that the proposed method is not only effective and efficient to converge design process to a desired solution, but also scientific, systematic, simple and easy to use.
