投入产出数学模型

针对企业安全管理工作中的安全性评价问题提出了多级模糊综合评价方法，并以投入产出数学模型进行了企业安全经济的分析。

Through technological designing and developing , the database structure is determined , and the division of model , system function analysis and function design are accomplished . A method of multistage fuzzy comprehensive evaluation is suggested for safety evaluation in occupational safety management .

给出了3类动态投入产出系统的数学模型，重点研究了投资时滞为多年但仅考虑一个投资周期的拓展动态投入产出模型（模型Ⅱ）均衡解的存在性。

The mathematic models of three kinds of dynamic I / O systems have been given . The model ,ⅱ, with multi-time-lag but only one cycle of investment , is the main subject for discussion .

投入产出分析的Fuzzy数学模型

A fuzzy mathematical model of input-output analysis

讨论了投入产出法中的数学模型应用的矩阵运算，并利用Excel软件进行投入产出法的应用操作，使投入产出法能得到更广泛的应用。

This paper studies matrix calculation about input output analysis method , and uses the method to forecast input output cost of enterprises with the help of Excel software , so as to make the method applied more broadly .

投入产出模型：一个系统投入和产出的数学模型。

Input-output model : A mathematical model of inputs and outputs to a system .

第六章是论文的结束部分。论文的结论是：通过数学方法对投入产出法进行改进研究，可以优化投入产出数学模型，修正适时编制投入产出表时的投入和产出系数；

The sixth chapter end up this paper , it draws a conclusion : the input-output mathematics model can be improved through mathematics research to the input and output method , the input-output coefficient can be Simultaneously amended ;

依赖于同质性和比例性假设，并遵循生产与使用、投入与产出、国民收入与其最终使用等平衡关系，建立了投入产出数学模型。

The establishment of mathematical input-output models depends on the suppositions of homogeneity and proportionality , following the balancing relations between production and use , input and output , national income and its final disposition .
