As the competitiveness of China's food industries tends to decrease year by year, the effects of foreign direct investment (FDI) on the competitiveness improvement is investigated for a sample of China's food industries. Estimates of labor productivity in domestic owned plants are constructed and employed as the dependent variable. The capital intensity and plant-scale economies in domestic owned...
The situation of the safety production of enterprise is very severe in China due to the insufficient safety investment. The accounting has unique effect if using it to manage the safety investment activity. However, the accounting function in safety investment of enterprise in China does not effectively mobilized. Based on the factors, Current situation of accounting of safety investment of enterprise...
With theory of technology innovation, enterprise development strategy and applying statistics applied, this paper summarizes and abstracts factors of high-tech enterprise independent innovation capability. It analyzes and modifies the factors using research and factor analysis, then makes the evaluation index system of high-tech enterprise independent innovation capability.
The urban technology innovation system is an important driving force of urban development, this article evaluates the construction degree of Dalian' technology innovation system form four aspects: Organization construction, market mechanism, power mechanism and support system. First, based on these four aspects the author establish an evaluation index system; Second, build the evaluation model of...
In the course of evaluation of coal industry security, determination of the index weight is the key problem to decide whether the evaluation result is scientific. Triangle-adjustable fuzzy number is adopted in this paper, which enhances the objectivity of evaluation. The multi-experts decision is made convergence twice by means of the clustering analysis theory. The first convergence eliminates abnormal...
Scientific evaluation on reverse logistics system of city solid wastes is an important method for optimizing reverse logistics system operation of the city solid wastes, for finding the bottleneck to influence the efficiency of the reverse logistics system, for optimizing and improving the management process, and finally for improving the overall performance. From the perspective of circular economy...
The modernization of agricultural logistics involves the operating efficiency and quality of the entire economy, agricultural modernization and the fundamental interests of farmers. Thus the development of modern agricultural logistics is one of the important means to the promotion of competitiveness of agricultural produces. Adopting the factor analysis model, this article analyzes the conditions...
The role of information technology in enterprise has changed fundamentally. Emphases on IS return researeh have turn into how to promote competition advantage and how to inerease the value of IS investment. After analyzing the partieularity and complexity of IS investlnent project, an ex-ante evaluation model is set up, which aims to find the real value of IS investment and to provide the decision...
In order to improve energy investment efficiency, it is necessary to measure energy investment efficiency scientifically. And so far, no scholars both at home and abroad have studied for energy investment efficiency systematically. Using for references of investment efficiency of predecessors, this paper puts forward the concept of energy investment efficiency. It points out that the necessity of...
ACO is a new distributed intelligent biologically-inspired algorithm simulated evolution, and is widely used for solving various combinatorial optimization problems. The simulation results showed that this method is better than genetic algorithm in the iterations and results. So ant system algorithm with variance as the risky measure indexes is better than basic ACO and genetic algorithm in real estate...
There are usually multiple mineral deposits in one mineral area, so comprehensive exploitation is very important. Based on the interpretation of the working mechanism of neural network expert system, first, a mining condition evaluation index system was designed; second, according to the mining conditions of the mineral deposit, a three-layer neural network was built; third, a detailed study on knowledge...
In the development of complex systems the requirements for the system will almost always remain uncertain late into the software development. In gas turbine engine control systems at Rolls-Royce, typically 50% of requirements will change between Critical Design Review and Entry into Service. Ignoring or not planning for requirements uncertainty will cause scrap and rework that will manifest later...
Proceed from economy theory, this paper selects the best treatment method of slopes based on minimum investment principle. In economic analysis, the most important one is to find failure probability of slopes. Traditional calculation method doesn't consider the fuzziness of mechanical parameters. However, the fuzziness exists objectively. In this paper, fuzzy technique is introduced and failure probability...
Based on the in-depth analysis of urban network's characteristics, a comprehensive model composed of an evaluation index system and a novel evaluation methodology is described for studying environmental effects that planning schemes might cause if they were implemented. The novel model focuses on various typical perspectives, such as pollution emissions, carbon emissions and environmental coordination...
In order to resolve the redundant information in High-tech project evaluation, a high-tech investment risk evaluation model combining a rough sets RS and the RBF neural network is presented. First using the rough set's powerful numerical analysis capabilities, this model does the attribute reduction on the evaluation index which reduces the training data of RBF neural network and simplifies the network...
This paper defines the connotation of industrial independent innovation capability, based on which, it establishes an evaluation index system of industrial independent innovation capability from the view of industrial input and output. The system includes three class indexes. First class index includes 4 indexes: innovative resources input capability, independent transformation capability, innovation...
On all countries building an innovation — oriented national strategy, this issue studies on the establishment of evaluation index system of science and technology policy implementation level and states technique and criterion of concrete evaluation indexes detailed. And the author indicates applied prerequisite and range.
Science and technology are playing more and more important role in the upgrade of the industry in Wuhan. The efficiency of input and output in science and technology is an issue worthy of being studied. So, the paper makes an analysis and evaluation of the input-output efficiency in science and technology of Wuhan industry by factor analysis method. Finally, the paper draws conclusions that the number...
Power Plant Construction project plays a very important role in ensuring the national economic and social development, promoting industrial structure adjustment and optimizing the allocation of resources, while post project evaluation is a vital sector and link as well to test whether Power Plant projects achieve the construction goal and benefit effect. Through analyzing and research the existent...
Through several field surveys about Wenchuan earthquake stricken area, according to land damaged characteristics and the local basic conditions, it is concluded that the reclamation of damaged land in Wenchuan earthquake is restricted by natural conditions,basic conditions and social-economic conditions which are related with various factors or targets. In light of analytic hierarchy process, assessment...
