【摘要】：設(shè)計(jì)活動(dòng)間的重疊是并行研發(fā)項(xiàng)目的基本特征,重疊可以縮短工期,但也會(huì)帶來返工風(fēng)險(xiǎn),并增加與重疊并行性相關(guān)的成本.為探索重疊活動(dòng)間的多次溝通對(duì)返工風(fēng)險(xiǎn)的影響,本文構(gòu)建了基于多次溝通-風(fēng)險(xiǎn)的重疊模型,建立了上游活動(dòng)信息變更率和下游活動(dòng)返工影響敏感度計(jì)算模型,在此基礎(chǔ)上構(gòu)建了活動(dòng)返工風(fēng)險(xiǎn)和返工量計(jì)算模型及與重疊并行性相關(guān)的成本模型,進(jìn)一步,以成本節(jié)約值最大化為目標(biāo)函數(shù),采用Fmincon算法優(yōu)化得到了多次溝通時(shí)最佳的溝通次數(shù)和溝通間隔.最后,結(jié)合典型案例,在對(duì)重疊活動(dòng)間溝通變量?jī)?yōu)化的基礎(chǔ)上,對(duì)設(shè)計(jì)結(jié)構(gòu)矩陣(DSM)進(jìn)行排序優(yōu)化并將優(yōu)化結(jié)果進(jìn)行仿真,結(jié)果表明本文提出的方法可降低項(xiàng)目時(shí)間和成本.
[Abstract]:Overlap between design activities is the basic feature of parallel R & D projects. Overlap can shorten the duration of the project, but it will also bring the risk of rework and increase the cost associated with overlapping parallelism. In order to explore the influence of multiple communication between overlapping activities on rework risk, an overlap model based on multiple communication-risk is constructed, and a calculation model of upstream activity information change rate and downstream activity rework impact sensitivity is established. On this basis, the calculation model of activity rework risk and rework volume and the cost model related to overlapping parallelism are constructed. Furthermore, the goal function is to maximize the value of cost savings. The Fmincon algorithm is used to optimize the optimal communication times and communication intervals. Finally, based on the optimization of communication variables between overlapping activities, the optimization of design structure matrix (DSM) is carried out and the results are simulated. The results show that the method proposed in this paper can reduce the project time and cost.
