Under the new historical condition, strengthening the communication and popularization of science and technology is both the requirement to implement the national development strategy and need for social development as well as the basis and key point for the development of popularization of science itself. Relevant data of five characteristic indexes, talents, funds, place, communication and activity...
There is great scope and enormous potential for economic cooperation between China and India. The investment between two countries is far from the due standard owing to so many obstacle factors. The Chinese enterprises who invest in India are facing poor investing environment. In this thesis, the investing environment in India can be evaluated objectively and comprehensively by questionnaire survey...
This paper considers optimization chemical control in integrated pest management. The impulsive models of the pest management consisting of the spaying pesticides and the pesticide effect of crops are established and analyzed. Making use of the optimal control theory to solve the optimal dosages of the pesticides and the time intervals with spaying pesticides. Thus, given an optimal pest management...
To evaluate the development of 9 provinces (or cities) of China, we analyze the relative advantage of different provinces ities) from four aspects: economy, society, sustainable development and politics and culture. Considering the difference of resource of rent provinces (or cities), we provide a new evaluation model. Specifically, first, the provinces (or cities) are divided into three regions,...
The correlation degrees among carbon emissions and influencing factors help to make correct judgment and insightful short and long term policies for the low-carbon economy. According to the carbon emissions data provided by American Oak Ridge National Laboratory Carbon Dioxide Information Analysis Center (CDIAC), from which we selected the data of world's top 11carbon emitting countries, a comparative...
Equipment is the foundation and precondition of the survival of the enterprises, the advanced level and the update problem of which directly affect the enterprise's survival and development, which also are paid more and more attention. Based on network model, this paper studied the update problem of the construction equipment, through changing the equipment update problem to the shortest path problem...
In order to study the relationship between transporation and economic growth from he macro, in this paper he concepts of impact factor and converson efficiency of tansporation level are introduced. Based on the analyss of New-Clascal Growth Theory, an economic growth model wih transporation factors is set up. Through analyss of he model the action mechanism and influence path of tansporation on regional...
On the basis of systematical analysis of the competitiveness, target elements, the main elements and resource elements of innovative enterprises, the power system model of enhance the competitiveness of innovative enterprises was put out. Basing on the system dynamics theory, this model revealed the rule of competitiveness enhance of innovative enterprises.
This paper evaluated the innovation capacities of Shandong Province and Guangdong Province quantitatively using the regional innovation capacity evaluation system. Then the author compared different innovation degree associated with local economic growth using gray correlation theory. Finally this paper presented several suggestions of improving innovation capacity.
In this paper, linear quadratic stochastic zero-sum differential games for discrete-time Markov jump systems are discussed. It is shown that the existence condition of finite horizon stochastic zero-sum games is equivalent to the solvability of the associated difference Riccati equations, and that of infinite horizon stochastic zero-sum games is equivalent to the solvability of the associated algebraic...
With the development of medical and health services, as well as the advance of treatment technology, there are more health demands in our society. The rapid growth of the absolute value of medicare fund expenditures has put lots of pressures on countries' national health care system. However, the medical insurance fund is the direct key to the health care system. The increases of fund expenditures...
Due to process disturbances and some uncertainties, the process operating performance will deviate from the optimal operating point along with time, so it is very important to develop strategies for online operating performance assessment on optimality. However, a little work has been published in this research area to our knowledge. In this study, a new online operating optimality assessment method...
This paper will establish a reasonable evaluation index system and research method as a solution of main problems. First of all, according to the specific problems on solar house design, evaluation index system is constructed, Then, the idea of integrating the AHP method and the intuitionistic fuzzy entropy method is proposed to determine the weight coefficient of each index; Finally, using the grey...
Location problem is about selecting one or more facility's geographical location to make the objective function to be optimal. in this article, firstly, we introduce three location models of project, single source of continuous, discrete location model for single source and multiple source location model of discrete location model. Then we illustrate three numerical examples and provide solution by...
Currently, when tourists' demands of the standard massive tourism are transferring toward personal and systematic tendency, the original model of meeting demands by accommodation, travel, shopping, entertainment etc. is meeting with trouble. Tourism supply chain can assist tourism companies and partners in cooperating well. On the one hand, it integrates tourism factors and organizes tourism products...
At present, the ratio of unemployment was rising slightly in China, and the employment pressure was bigger and bigger than before. To make a scientific explanation for unemployment is the key to solve the focus problem of employment. The study listed seven factors that affect unemployment of labor force by the method of factor analysis and principal component analysis. Seven factors were defined as...
