摘要
優(yōu)化設(shè)計(jì)是最優(yōu)化理論和方法在設(shè)計(jì)中的應(yīng)用,力求以最低的成本、最高的效率達(dá)到最優(yōu)的目標(biāo)。本文通過(guò)一系列的分析,對(duì)控制網(wǎng)的優(yōu)化方法進(jìn)行分析,說(shuō)明可行性。
為了解決控制網(wǎng)優(yōu)化設(shè)計(jì)問(wèn)題,本論文分兩大部分,GPS網(wǎng)的優(yōu)化設(shè)計(jì)和GPS網(wǎng)的精度和可靠性,在 GPS網(wǎng)形設(shè)計(jì)中,首先根據(jù)工程的特點(diǎn)和GPS網(wǎng)設(shè)計(jì)規(guī)范的要求,大致確定網(wǎng)的規(guī)模,用圖論和樹的有關(guān)算法推導(dǎo)出GPS網(wǎng)形中點(diǎn)、邊、異步環(huán)之間的關(guān)系,然后給出一種生成網(wǎng)形的算法,自動(dòng)生成初步網(wǎng)形,并用模擬法在顧及精度和可靠性準(zhǔn)則下對(duì)初步網(wǎng)形進(jìn)行優(yōu)化設(shè)計(jì),確定最終網(wǎng)形,并按最小路徑方法生成觀測(cè)方案。

OPTIMIZING DESIGNING OF CONTROL NETWORK
ABSTRACT
The optimization design is a application of the most optimizative theory and method in the design. It is hopeful that the best target obtained through the expenditure of the fewest cost and the best efficient. The essay is a feasibility report of the optimization design of GPS control network’s methods by a series of analysis.
This paper consists of two parts: Optimizing designing of GPS control network and the Precision and Reliability of GPS network. When designing a GPS control network ,its scale should be predicted as the project requested and the GPS surveying standard disciplined. According to the relationship among GPS points , edges and nonsynchronous loops, we can use an algorithm of Graphic Theory to produce a network when given the number of points and the maximum edges of each nonsynchronous loop, after being modified by using simulate optimizing method we can draw the ultimate network, then the observation plan can be gained by using the best way algorithm.
