AN APPLICATION OF A MULTI-OBJECTIVE OPTIMAL SATISFICING TECHNIQUE TO CONSTRUCTION ACCURACY CONTROL OF CABLE-STAYED BRIDGE

斜拉桥施工精度控制可归结为一个多目标优化问题。在这种情况下，有用的目标函数的数量变得非常大。这项研究项目的首席研究员提出了一种有效的方法，称为满意权衡方法，用于解决具有大量目标函数的此类问题。本研究的主要目的之一是将满意度权衡方法引入到具有一定人机界面的施工精度控制系统中，以减轻决策者在斜拉桥施工精度控制中的负担。在此基础上，编制了精确权衡方法的计算机程序，使权衡分析变得更加容易。在下一年的研究中，在精度控制系统中建立了精确权衡方法的计算机程序。此外，通过将输入输出界面可视化，制作了一些人机界面设备，使决策者可以非常方便地使用该系统。其次，将该系统应用于一些实际的斜拉桥数据，以期从实用的角度加以完善。最后，看来我们已经建立了一套实用程度足够高的斜拉桥精度控制系统。

The construction accuracy control of cable stayd bridge can be formulated as a multi-objective optimization. In this event, the number of objective functions useally becomes very large. The head investigator of this research project has suggested an efficient method, called the satisficing trade-off method, for solving such a problem with a great number of objective functions. One of main aims of this research is to decrease the burden of the decision maker in construction accuarcy control of cable stayd bridges by incorporating the satisficing trade-off method into the construction accuracy control systems with some devices of human interface.In the first year of the research term, the computer program of the satisficing trade-off method was built in the construction accuracy control system. Furthermore, the computer program of the exact trade-off method which makes the trade-off analysis much easier was accomplished.In the next year of the research term, the computer program of the exact trade-off method was built in the accuracy control systems. In addition, some devices for the human interface were made by visualizing the input-output interface so the decision maker can utilize the system very easily. Next, the system was applied to data of some real cable stayd bridges in order to be polished up from a practical viewpoint. Finally, it seems that we have established an accuracy control system for cable-stayd bridge with a sufficiently high degree of practical use.
