项目摘要

Current year is the final year of a research concerned, and the following two items were executed based on the study results of the last year as well as the year before last.1) Construction of parallel calculation system and program development of genetic algorithm : The further tuning to the program developed to make the parallel calculation system which was introduced by this research promotion at the first year for the optimization process of the genetic algorithm was carried out and the computational environment to enable us to execute a high-speed calculation was constructed. As a result, whether the efficiency of the calculation of the parallel computing was actually possible up to which extent was directly examined and the special technique of the programming for the parallel computation and the method of efficiency improvement were studied, and the basic data for the research in the future was gathered.2) Application of uncertain factor to optimization process by introduction of probability theory Among the design loads, the earthquake force and the wind loading has the element of the uncertainty in both time and space field. It is necessary to put the influence of these loads on the building during the use period in the evaluation for the life cycle. A highly effective calculation process was constructed with the accomplishment of a basic research to construct the computational morphogenesis which could handle the influence of the uncertainty for a theoretical examination

本年度是该研究的最后一年，在去年和前年研究成果的基础上，进行了以下两项工作。1）并行计算系统的构建和遗传算法的程序开发：进一步调整开发的程序，使并行计算系统，这是由本研究推广的第一年，为优化进行了遗传算法的过程，并构造了使我们能够执行高速计算的计算环境。结果，直接检查并行计算的计算效率实际上是否可能达到何种程度，并研究并行计算的编程的特殊技术和效率提高的方法，2）引入概率论，将不确定性因素应用于优化设计过程中。在设计荷载中，地震力和风荷载在时间和空间上都具有不确定性。在对建筑物进行寿命周期评价时，有必要考虑这些荷载在使用期内对建筑物的影响。通过基础研究的完成，构造了一个高效的计算过程，构建了能够处理不确定性影响的计算形态发生模型，并进行了理论验证
