Early Warning Indicator

Coal and gas outburst is one of the major disasters in the safety production of coal mine. According to the mechanism of coal and gas outburst, based on the comprehensive analysis of various influencing factors of coal and gas outburst, with the principles of selected early warning indicator, the basic information database of coal and gas outburst warning is constructed, and the information data query function is realized. The mathematical model of coal and gas outburst warning is established by the logistic regression analysis based on the gas concentration, the gas desorption index of drill cuttings, and the initial velocity of gas emission from the borehole. The multivariate information coupled warning was conducted according to the selected early warning indicator system, and the early warning level was divided with the result of early warning. The design and research of the coal and gas outburst warning system are carried out based on the geographic information system (GIS). The coal and gas outburst warning system was verified by taking the Tunliu mine of Lu’an Group as an example. The establishment of the early warning system is a new technical way to the early warning management of coal and gas outburst and can provide a guarantee for coal and gas outburst prevention.

Our objective is to establish the patent infringement litigation early warning model and early warning indicator system for pharmaceutical companies. Reversely generate the warning model based on incentives of patent infringement litigation. A combination of qualitative and quantitative methods were used to determine the specific early warning indicators. According to the hierarchical analytical process, the three-tier warning indicator was established system including the target layer and factors, and three stages of the early warning indicator system: were put forward: preliminary warning phase, target company judging phase, and accurate early warning stage. Quantified statement was given to all the warning indicators, to establish a mathematical model.
