In order to break through the performance bottleneck of the scientific solution, a method was presented to optimize and evaluate the performance of the scheme by introducing technology combinations while fully considering technical risks. Because the risks brought about by the immaturity of technology itself will cause uncertainty problems. In order to reasonably estimate the impact of technology combination on the degree of performance optimization, an evaluation method of technology index impact based on technology maturity was adopted, and a method was presented to evaluate the optimization results of the scheme performance caused by various technology combinations by using a combination of technology uncertainty impact and scheme performance index tree. Simulation results show that, this method, taking into account the risk and impact caused by technology maturity, makes the evaluation result more scientific and reasonable. Finally, an example of evaluating the high-speed civil transportation model was given to illustrate the applicability of this method. | | 查看全文查看/发表评论下载PDF阅读器 | |
