We employed the assumption on the differences in future increase rates of companies, taking into account of the expected Economic Value Added (EVA) discount and the capital investment, to establish a high increase model, a two-stage EVA discount model and a three-stage EVA discount model for the intrinsic value assessment. Those models eliminate the great fluctuation of free cash flow in calculating the capital expenditure by setting aside the cash flow of the company’s investment in the year and considering only the capital cost. This method needs only to assess the EVA flow in different year in probing the intrinsic value of a company, thus give more consistent conclusion than conventional methods.展开更多

In the issues related to seismic and rockburst hazards, the analyses of distributions of stress component values in the rock strata are performed, similarly as those of deformation parameters of the strata. To do this, commercial computer programs are used which function on the basis of the finite element-, separate element-, finite difference-, boundary element methods, or individually designed computer programs. They enable to obtain information, unattainable with other methods, being of importance for further concluding on those hazards. The programs based on applying those methods have contributed to important progress and development of science in the domain of analyzing and predicting the hazards. To this end, the commercial computer programs are used that are based on the methods of: finite elements, separate elements, finite differences, boundary elements, etc., or on individually developed computer programs. They enable to obtain information, unavailable using other methods, being of vital importance for further concluding on these hazards. The programs based on these methods have contributed to essential progress and development of science in the field of analysing and predicting the hazards. Apart from their obvious advantages, they have many drawbacks that hinder their practical, routine application. To allow making these type of analyses, without the necessity of constructing complicated models and knowing the detailed geomechanical parameters of rocks, together with laborious computation using a high-rank computer hardware, an analytical-empirical method has been developed at Central Mining Institute, Poland, to make prediction (modelling) of the distribution of pressure values (vertical component of stress) in SIGMAZ coal seams. It is based on geophysical measurements, generalized for the conditions of the Upper Silesia Coal Basin, of disturbing effect of the mining edge and tectonic faults on the state of stress. The paper presents methodological and programming assumptions of the method. The scope of its application has been discussed, and results of demonstration analyses for Polish hard coal mines presented. There have been also given the advantages of the method in relation to classical numerical methods.展开更多

The water resource plays an important role in the sustainable development of this system. The value of water conserved by the forest is influenced by natural, economic and social factors. In this paper, the water quality, per capita water resources, per capita GDP and population density are chosen as indices to construct an index system for a comprehensive evaluation of water resources value. The weights of these indices are 0.443, 0.31, 0.141 and 0.106 respectively, which are determined by the analytic hierarchy process(AHP) method. The water resources value has been assessed by the fuzzy comprehensive evaluation model. The results show that the water resources value in the Hani Rice Terraces System is 4.25 RMB/m^3. Evaluating the value of water resources in the Hani Rice Terraces System can provide a reference for ecological compensation, for raising public awareness of the importance of protecting the system, and ultimately achieving its sustainable development.展开更多

Based on the essential principle of sustainable development, this paper puts forward a general idea on water resources optimization and eco-environmental protection in Qaidam Basin, and identifies the competitive multiple targets of water resources optimization. By some qualitative methods such as Input-output Model & AHP Model and some quantitative methods such as System Dynamics Model & Produce Function Model, some standard plans of water resources optimization come into being. According to the Multiple Targets Decision by the Closest Value Model, the best plan of water resources optimization, eco-environmental protection and sustainable development in Qaidam Basin is finally decided.展开更多

Also, in the previous study, we suggested the target domains and entities of product and process based on the TQM Matrix and view point of Three Dimensional Unification Value Models for managing quality of organization systems. Furthermore, in the previous study, we suggest the Common Management Process of organizations. Based on the above suggestion, in this paper, we would like to propose the Common Management Process Model of Total Quality Management based on the consideration of situation analysis and more precise definition of TQM Matrix and Three Dimensional Unification Value Model of “Product and Process”. Improvement of quality and efficiency of organization management can be expected by the integration of conventional different management such as quality assurance, quality improvement, risk management, investment individually from the view point of common management process.展开更多

The traditional corporation valuation methods don not work well when encountering these types of corporations. Just in these backgrounds, a new method called CVBC model is brought forward to evaluate these types of corporations in our article, which is based on the customer lifetime value. In essence, it extends the concept of customer lifetime value and combined with the traditional financial methods, then creates a new valuation method. It can work well to the corporations, which have been said before. The principle, mathematical model of the method and the effect of the practical application are discussed in detail.展开更多

We separate the model space into N-subspaces based on their physical properties or computational convenience and solve the N-subspaces systems by damped least-squares and singular-value decomposition. Since the condition number of each subsystem is smaller than that of the single global system,the approach can greatly increase the stability of the inversion. We also introduce different damping factors into the subsystems to reduce the tradeoffs between the different parameters. The damping factors depend on the conditioning of the subsystems and may be adequately chosen in a range from 0.1 % to 10 % of the largest singular value. We illustrate the method with an example of simultaneous determination of source history,source geometry,and hypocentral location from regional seismograms,although it is applicable to any geophysical inversion.展开更多

Aiming to transform the potential to a reality, customer values are systematically analyzed on basis of Value-Focused Thinking, which includes five aspects of identification, expression, organization, measurement and utilization. Nine types of heuristic questions are firstly used to identify customers' value statements. These statements are then transformed into a common expression. Then means-ends analysis and part- whole analysis are used to infer the relationships among statements, and result in a means-ends network and a hierarchical value tree for organizing them. To measure achievement of customer values, a decision model is used to identify and select the measurable attribute of each value statement, and a value model is then constructed from the set of measurable attributes. Finally, customer values are actively applied to support decision customer procurement, website design, creative or improved design of industrial robots. making of展开更多

文摘This article is based on traditionally intrinsic value assessment model. We employed the assumption on the differences in future increase rates of companies, taking into account of the expected Economic Value Added (EVA) discount and the capital investment, to establish a high increase model, a two-stage EVA discount model and a three-stage EVA discount model for the intrinsic value assessment. Those models eliminate the great fluctuation of free cash flow in calculating the capital expenditure by setting aside the cash flow of the company’s investment in the year and considering only the capital cost. This method needs only to assess the EVA flow in different year in probing the intrinsic value of a company, thus give more consistent conclusion than conventional methods.

文摘The Hani Rice Terraces System, based on gravity-flow irrigation, is one of the Globally Important Agricultural Heritage Systems(GIAHS) pilot sites selected by FAO in 2010. The water resource plays an important role in the sustainable development of this system. The value of water conserved by the forest is influenced by natural, economic and social factors. In this paper, the water quality, per capita water resources, per capita GDP and population density are chosen as indices to construct an index system for a comprehensive evaluation of water resources value. The weights of these indices are 0.443, 0.31, 0.141 and 0.106 respectively, which are determined by the analytic hierarchy process(AHP) method. The water resources value has been assessed by the fuzzy comprehensive evaluation model. The results show that the water resources value in the Hani Rice Terraces System is 4.25 RMB/m^3. Evaluating the value of water resources in the Hani Rice Terraces System can provide a reference for ecological compensation, for raising public awareness of the importance of protecting the system, and ultimately achieving its sustainable development.

文摘In order to realize sustainable development of the arid area of Northwest China, rational water resources exploitation and optimization are primary prerequisites. Based on the essential principle of sustainable development, this paper puts forward a general idea on water resources optimization and eco-environmental protection in Qaidam Basin, and identifies the competitive multiple targets of water resources optimization. By some qualitative methods such as Input-output Model & AHP Model and some quantitative methods such as System Dynamics Model & Produce Function Model, some standard plans of water resources optimization come into being. According to the Multiple Targets Decision by the Closest Value Model, the best plan of water resources optimization, eco-environmental protection and sustainable development in Qaidam Basin is finally decided.
文摘In the previous study, we suggested the concept of new TQM based on the consideration of basic concept of Quality Control. Also, in the previous study, we suggested the target domains and entities of product and process based on the TQM Matrix and view point of Three Dimensional Unification Value Models for managing quality of organization systems. Furthermore, in the previous study, we suggest the Common Management Process of organizations. Based on the above suggestion, in this paper, we would like to propose the Common Management Process Model of Total Quality Management based on the consideration of situation analysis and more precise definition of TQM Matrix and Three Dimensional Unification Value Model of “Product and Process”. Improvement of quality and efficiency of organization management can be expected by the integration of conventional different management such as quality assurance, quality improvement, risk management, investment individually from the view point of common management process.
文摘This paper discusses an organizational model to be used for both conventional and virtual organizations. The model deals with variable relationships within an organization and provides a framework for overall organizational design that may include relationship among different design variables and external relationship with environment. Based on the researches of virtual organization, this paper also illustrates the new model of organization in the real world such as Beijing 2008 Olympic games and Dongfeng Automobile group.
文摘Most of the Internet or e-commerce corporations have few earnings or even none. The traditional corporation valuation methods don not work well when encountering these types of corporations. Just in these backgrounds, a new method called CVBC model is brought forward to evaluate these types of corporations in our article, which is based on the customer lifetime value. In essence, it extends the concept of customer lifetime value and combined with the traditional financial methods, then creates a new valuation method. It can work well to the corporations, which have been said before. The principle, mathematical model of the method and the effect of the practical application are discussed in detail.

文摘A method for simultaneous determination of mixed model parameters,which have different physical dimensions or different responses to data,is presented.Mixed parameter estimation from observed data within a single model space shows instabilities and trade-offs of the solutions. We separate the model space into N-subspaces based on their physical properties or computational convenience and solve the N-subspaces systems by damped least-squares and singular-value decomposition. Since the condition number of each subsystem is smaller than that of the single global system,the approach can greatly increase the stability of the inversion. We also introduce different damping factors into the subsystems to reduce the tradeoffs between the different parameters. The damping factors depend on the conditioning of the subsystems and may be adequately chosen in a range from 0.1 % to 10 % of the largest singular value. We illustrate the method with an example of simultaneous determination of source history,source geometry,and hypocentral location from regional seismograms,although it is applicable to any geophysical inversion.

文摘Internet commerce of industrial robots has the potential to provide higher value to customers in downstream industries. Aiming to transform the potential to a reality, customer values are systematically analyzed on basis of Value-Focused Thinking, which includes five aspects of identification, expression, organization, measurement and utilization. Nine types of heuristic questions are firstly used to identify customers' value statements. These statements are then transformed into a common expression. Then means-ends analysis and part- whole analysis are used to infer the relationships among statements, and result in a means-ends network and a hierarchical value tree for organizing them. To measure achievement of customer values, a decision model is used to identify and select the measurable attribute of each value statement, and a value model is then constructed from the set of measurable attributes. Finally, customer values are actively applied to support decision customer procurement, website design, creative or improved design of industrial robots. making of
