Proceeding of the Joint International Symposium on Deformatuon Monitoring. 2-4 November, 2011. Hong Kong. China. Report. Geodetic deformation measurements and analysis concepts are one basis for minimizing the risk of, e. g. unexpected collapses of artificial objects and geohazards. The idea behind these activities is the need of the society in minimizing the negative environmental impacts. An optimal configuration for measurement setups and all other decisions shall therefore review and rate the risks of an individual project. In this study, a methodology is introduced that allows considering consequences or costs within Geodetic decisions in order to meet the real requirements. The theoretical concept is based on the so called utility theory in decision making. This allows to introduce costs or consequences for type I and II errors. Finally, the most beneficial decision is chosen which leads to the minimum costs or consequences for the specific project. Additionally, this procedure allows identifying the most beneficial measurements in Geodetic monitoring to reduce the risk of an individual process. The paper shows the general concept of the decision making process with consideration of risk (cost, consequence) values. The theoretical concept is applied to two examples in landslide monitoring and in the quality assessment within an automatic inspection process.
