Cloud model for risk evaluation of coal mine intelligent projects and its application
In order to solve the problems of difficulty in quantifying the indicators and difficulty in taking into account randomness and fuzziness in the evaluation process of the risk of the coal mine intelligentization project,the cloud model theory was adopted to carry out a quantitative and comprehensive evaluation of the system.First of all,based on the coal mine informationization system construction project,a multi-dimensional analysis was carried out to establish a multi-indicator and multi-dimensional evaluation system of the project risk.Then,the combination of hierarchical analysis(AHP)method and criteria importance though intercrieria correlation(CRITIC)method was used to assign weights,determine the weight matrix of the indicators,and the cloud model was used to realize the conversion between the quantitative and qualitative indicators,to complete the evaluation of the risk of the coal mine intelligence project,and to put forward the targeted policy according to the evaluation results.The cloud model was used to realize the quantitative and qualitative conversion of indicators,complete the risk evaluation of the coal mine intelligentization project,and put forward targeted policies based on the evaluation results to minimize the existing risks of the project.Finally,taking a coal mine of National Energy Group as an example,the risk evaluation of the construction and implementation process of coal mine intelligentization project was carried out.The results show that the cloud model can realize the quantitative evaluation of project risks,and the results of risk evaluation coincide with the actual situation on the site;the results of risk evaluation can help to solve the hidden risks on the site and improve the ability of risk control.
