【摘要】：本文构建了一套石油化工码头装卸作业安全预警指标体系,与其它常用安全预警模型对比之后,可拓理论比较适合码头动态、复杂的特点,选择其作为预警模型并予以应用研究。基于Lab VIEW8.5,一种可视化编程语言的开发平台,可用于配置程序,实时的处理大量复杂的数据。运用该软件对预警体系编制程序以实现对石油化工码头装卸作业安全管理现状进行评价,及时发出预警信号。结合石油化工码头装卸过程实际,设计和实现了一个实例,构建了石油化工码头装卸过程预警指标体系,包括6个一级指标和33个二级指标。文中用层次分析法确定指标客观权重,采用差异驱动原理确定指标的客观权重,由于主观赋权法和客观赋权法对同一指标权重确定存在的差异,故最后对两种方法进行组合,最终确定了石油化工码头装卸过程预警指标的组合权重。其中,对差异驱动原理的计算过程进行Lab VIEW编程,避免了繁重的人工计算工作。该预警程序分别对石油化工码头装卸过程的一级预警指标即人员因素指标、工艺设备设施指标、作业安全指标、环境因素指标、管理因素指标和应急管理指标进行预警等级评估,结果表明所有指标均为无警状态。因此,根据最大关联度准则,整个石油化工码头装卸过程为安全状态。本实例中,人员因素指标的权重最大,然而与无警的关联程度最低,所以有必要提高该码头的人员因素安全管理水平。环境因素指标与无警关联程度最高。该预警模型在某石油化工码头装卸过程中的应用表明可拓理论能够较好的对石油化工码头装卸过程安全状况进行预警分析,以综合关联度作为评价准则,客观有效,基于Lab VIEW的计算机程序使得运算更加快速准确。用相应的指示灯亮来实时显示预警等级结果直观且易于察觉。
[Abstract]:In this paper, a set of safety early warning index system for loading and unloading operation of petrochemical wharf is constructed. Compared with other commonly used safety warning models, the extension theory is more suitable for the dynamic and complex characteristics of the wharf. It is chosen as an early warning model and applied to research. Based on Lab VIEW8.5, a visual programming language development platform, can be used to configure programs, real-time processing of a large number of complex data. The software is used to compile the program of early warning system in order to evaluate the present situation of safety management in loading and unloading operation of petrochemical terminal and send out early warning signal in time. Combining with the actual loading and unloading process of petrochemical wharf, an example is designed and implemented, and a warning index system for loading and unloading process of petrochemical wharf is constructed, which includes 6 first class indexes and 33 second class indexes. In this paper, the objective weight of the index is determined by analytic hierarchy process, and the objective weight of the index is determined by the principle of differential driving. Because of the difference between the subjective weighting method and the objective weighting method to determine the weight of the same index, the two methods are combined at last. Finally, the combined weight of early warning index of loading and unloading process of petrochemical wharf is determined. Among them, the calculation process of differential driving principle is programmed by Lab VIEW, which avoids the heavy manual calculation work. The early warning procedure has been applied to the first grade early warning index of the loading and unloading process of petrochemical wharf, that is, the index of personnel factor, the index of process equipment and facilities, the index of operation safety, the index of environmental factor. The management factor index and the emergency management index are evaluated, and the results show that all the indicators are no alarm state. Therefore, according to the maximum correlation degree criterion, the whole loading and unloading process of petrochemical wharf is safe. In this example, the weight of the personnel factor index is the largest, but the correlation degree with the police is the lowest, so it is necessary to improve the safety management level of the personnel factor in the wharf. Environmental factors had the highest correlation with no police. The application of this early warning model in the loading and unloading process of a petrochemical terminal shows that the extension theory can better analyze the safety situation of the loading and unloading process of the petrochemical terminal and take the comprehensive correlation degree as the evaluation criterion, which is objective and effective. Computer programs based on Lab VIEW make computing faster and more accurate. The corresponding indicator lights are used to display the warning level in real time and the results are intuitionistic and easy to detect.
