The constraints used in optimum design are determined by design criteria on the basis of elastic analysis. The most effective constraints are found by successful design experiences. A direct optimization method-the "net and search" method is then introduced in which a "net" is placed in the "most effective constraint surface". The process leads rapidly to a limit within some preselected tolerance, and no extreme points can be missed after a subsequent "search". The computer program is relatively simple...

The constraints used in optimum design are determined by design criteria on the basis of elastic analysis. The most effective constraints are found by successful design experiences. A direct optimization method-the "net and search" method is then introduced in which a "net" is placed in the "most effective constraint surface". The process leads rapidly to a limit within some preselected tolerance, and no extreme points can be missed after a subsequent "search". The computer program is relatively simple and straightforward. A feature of this method is that the intermediate results-which can be printed or plotted as graphs-are intuitive as they show clearly how the objective function varies with the parameters to be optimized, this is well suited to engineering applications.

在弹性力学分析和结构设计分析的基础上,可以建立一个很好的设计模型,而成功的设计经验则可从中找出最有效的约束。由此就可采用一个直接寻优方法——筛网法,其搜寻区局限在最有效约束面上,它的计算程序简捷,中间结果可打印或绘成曲线,直接反映目标函数与最优参数之间的关系,十分直观,便于工程应用。

This paper presents a method which may solve the quasi-geometric pro- gramming by means of a sequential geometric programming. In the method the dual problem of geometric programming is transformed into a maximizing pro- blem with the same constraints and logarithm objective function. It has been proved that both the problems have the same extreme point. The latter is solved by using a sequence of quadratic programming-GDQ algorithm. Further, in this paper the quasi-G.

This paper presents a method which may solve the quasi-geometric pro- gramming by means of a sequential geometric programming. In the method the dual problem of geometric programming is transformed into a maximizing pro- blem with the same constraints and logarithm objective function. It has been proved that both the problems have the same extreme point. The latter is solved by using a sequence of quadratic programming-GDQ algorithm. Further, in this paper the quasi-G. P. problem is actually solved by an iterative se- quence of GDQ. The pratical applications show that the above metioned method is quite efficient.

本文提出的算法是将拟几何规划通过Duffin公式等缩并办法化为序列几何规划 去逼近,再将几何规划的对偶问题化为相同约束下对数目标的极大化问题。为此,证 明了这两个问题具有相同的极值点。对于后一问题,采用序列二次规划解法GDQ 逼近之。所以,对于拟几何规划,实际上采用了序列几何规划对数对偶问题的序列 GDQ方法进行求解。 将上述算法通过一种特形式的几何规划进行了数值实验,算例表明该方法求解拟 几何规划是高效的。文中对一些结构优化问题进行应用,其中油船横仓壁和舯剖面优 化的效果是显著的。

This paper represents a simple method of reduction of dimensionality using the geometrical model of extreme points. The high-dimensimed sample points are projected to a 2 or 3 dimensioned space, keeping the similar relationship between original points. In this way, one can see the clustering distribution of high-dimensioned points in a plane of two dimensions.
