基于设计结构矩阵的舰船设计流程多分辨率建模

Multi-resolution modeling based on a design structure matrix for warship design process

针对因舰船设计系统规模庞大、设计任务间关系复杂,导致研制风险评估可信度较低的问题,本文提出一种符合系统流程分解细化、设计要素粒度提升的建模与评估方法。根据分辨率反映模型描述对象的精细程度,建立基于设计结构矩阵的多分辨率建模方法。并根据舰船方案设计的主要内容及其相互关系建立不同分辨率的设计结构矩阵,通过仿真对设计流程进度、费用进行评估,比较了不同分辨率模型的优缺点。在考虑建模工作量和难度的情况下,本文的结果为采用不同分辨率模型提供了模型之间差异量的近似估计方法。

Large-scale ship system design and the complex relationships among its design tasks carry low-confidence development risk assessments.In view of this,a modeling and assessment method is presented in accordance with system process breakdown and upgrade of design element granularity.By employing resolution to describe the level of modeling object details,multi-resolution modeling based on a design structure matrix(DSM)is presented.A DSM with differing resolutions was built according to ship design tasks and their involvement in warship scheme design.The schedule and cost of the design processes were evaluated by simulation;also,advantage and disadvantage of the different resolution models were compared.By comparing the difficulties and work of modeling with different resolutions,the difference between models with different resolutions was analyzed,and additionally an approximate method to estimate this difference between models was presented.
