基于功能区域方法的项目安全性分析

Safety analysis of a project based on function area method

利用传统方法进行工业项目的安全性分析,安全效益和安全价值都只能部分地反映系统的安全状况,所得分析结果对改善方案安全效果的作用很有限且应用性不强.通过引入价值分析理论,建立安全效益-价值联立方程和优选判据,再结合最合适区域法,最终形成了功能区域分析方法和理论.将功能区域方法应用于实际工程项目中,根据项目技术数据得出最合适曲线和区域分析结果,极大地改善了项目的安全价值和成本.

Using traditional methods to analyse the safety of industrial projects, safety benefit and value can only reflect the safety situation of system partially, the effect of analytical results on improving the safety situation of system is limited and its application is not satisfied. By introducing the theory of value analysis, safety benefit-value simultaneous equations and optimization criteria were built. Integrating the only area chart, the function area method （FAM） was finally developed. By applying this method to engineering projects, the only area chart and curves were obtained based on the technical parameters of projects, and the safety value and cost of projects were greatly improved.
