摘要
从企业是否有安全投资及事故损失分析了生产系统的三种状态.通过对生产系统中现金流量的变化分析了投入、产出和安全投资效益的内在变化关系.通过"有无对比法"对生产系统"有安全投资"与"无安全投资"进行对比,分析了生产系统在极端状态和现实状态两种状态下安全投资效益与事故损失之间的相互作用和变化规律,推导出通常情况下安全投资效益与事故损失的相互变化的4种关系,及其每种关系下的安全投资效益.推导结论为企业进行安全投资效益评估提供了理论依据,从企业角度建立起了评估安全投资效益的基本理论.
An evaluation model for safety investment benefits is presented. From the viewpoint of production system situations and capital flow transition between safety investment and accident loss in enterprises, the relationship of production investment, production output and safety investment benefits are deduced. By comparing production systems with and without safety investment, the variation rules and their model between safety investment benefits and accident loss in extreme and actual situations are analyzed. Finally, the expressions of safety investment benefits are derived for general actual cases. The proposed evaluation model can provide an important and scientific basis to evaluate safety investment benefits and be employed in a number of ways to improve it for enterprises and safety administrator.
