并行设计中任务量与时间模型的研究

STUDY ON TASK LOAD AND TIME MODEL IN CONCURRENT DESIGN

本文首先分析了以布尔量设计结构矩阵［１］表示活动联系与作用的不足和局限性，并由此引入了任务转移矩阵，建立了并行设计的任务量与时间模型。然后，在此模型的基础上，进一步分析了由耦合而引起的设计过程反复与迭代的规律，以确定影响该设计过程的主要因素——设计的驱动力，从而为多领域集成而引起的复杂性。

The lack in representing the relation between activities with Boolean Design Structure Matrix(DSM) is analysed,and task load and time model is also presented by introducing Task Transition Matrix(TTM)in this paper.Based on the model, we study the law of the repetition and overlay caused by coupled tasks in design process in order to identify the chief factor—design drive,which affects design process strongly.This can help implement Concurrent Design,which can be extremely complex and systematic because of the integration among multi domains.
