The most probable point (MPP) based reliability analysis is an approach that utilizes the safety index \u03b2 to measure the effect of uncertainties. Collaborative optimization (CO) is a two-level optimization method specially created for large-scale distributed-analysis applications. Simulated annealing-based collaborative optimization (SA\u2014CO) is one of the improved forms of CO that overcomes the difficulty of convergence given the existing of highly nonlinear consistency constraints. By combining the MPP-based reliability analysis method with SA\u2014CO, we present a new collaborative reliability analysis method under the environment of MDO to deal with uncertainties existing in MDO, that is, MPP\u2014SA\u2014CO. Demonstrated by two typical examples, the proposed method inherits the advantages of CO. Also, accurate and efficient results are obtained by employing simulated annealing algorithmic as the system level optimizer and it features response surface instead of disciplinary optimization.<\/jats:p>","DOI":"10.1177\/1063293x11420177","type":"journal-article","created":{"date-parts":[[2011,8,25]],"date-time":"2011-08-25T20:56:03Z","timestamp":1314305763000},"page":"245-254","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["Collaborative Reliability Analysis under the Environment of Multidisciplinary Design Optimization"],"prefix":"10.1177","volume":"19","author":[{"given":"Hong-Zhong","family":"Huang","sequence":"first","affiliation":[{"name":"School of Mechatronics Engineering, University of Electronic Science and Technology of China, Chengdu, Sichuan 611731, China,"}]},{"family":"Xiaoling Zhang","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, University of Electronic Science and Technology of China, Chengdu, Sichuan 611731, China"}]},{"family":"Wei Yuan","sequence":"additional","affiliation":[{"name":"Medical Systems Development Center, Toshiba Dalian Co.
