工程设计中三维协同设计的多任务优化

摘要

针对三维协同设计过程中的并行多任务冲突问题，建立了工程中三维协同设计的矩形组织结构和并行多任务执行工作流程，并利用系统的任务执行时间、系统任务设计成本和设计质量区间不确定性，结合设计工作逻辑关系和任务的一系列约束，基于系统的多目标决策要求，建立了三维协同设计并行多任务优化模型，实现了根据实际环境条件的不同复杂度任务的协同布置，满足了三维协同设计任务关于质量、效率和成本的目标要求。%In order to solve the problem of the parallel multi-assignment conflicting each other in three-dimensional col-laborative design, according to the feature of the multi sector, multi-collaborative assignment and network online collabo-ration, the article structured the rectangular organization structure and the parallel multi assignment execution process, es-tablished 3D collaborative parallel multi assignment optimization model , by using the interval uncertainty of the executing time, the design cost and quality. It achieved the collaborative arrangement that is provided with the assignment of different complexity degrees, and met the requirement about the target of quality, efficiency and cost in the actual conditions of 3D collaborative design environment.
