Fuzzy similarity ratio method is a widely used method of fuzzy decision-making, not only to classification, but also to sort. In this paper, we constructed a geochemical anomaly evaluation model using the Fuzzy similarity ratio method; we also program it with C# language and applied the model to practical work. Practice has proved that the fuzzy decision-making applies to the evaluation of geochemical anomalies can effectively improve the accuracy of the evaluation.

Networked control system is a subject of integrated computer technology, automatic control, communication technology and optimization theory, the effects of network scheduling on the property of network control system is a hot issue in the research of international academic circles in recent years. This paper introduces the basic composition and network control system schedulability analysis method, puts forward a network dynamic scheduling theory improved by real-time scheduling theory-Earliest Deadline First (EDF) dynamic scheduling algorithm. And the construction of multi loop networked control simulation platform based on CAN network using Truetime and Simulink toolbox. Simulation results show that, the earliest deadline first dynamic scheduling algorithm can make the performance of each loop controller in the uncertain network environment optimal.
