This article the technology system, and analyzes factors of technology system, the ecosystem evolution theory applied technology system. Constructed model of the evolution of technology systems, and finally the use of A model and system to promote the evolution of the A model, aims to improve the speed of evolution of technology systems, promoting technological development.
In this paper we consider the mechanism design of traffic BOT project auction. We set up the model of traffic BOT project auction where firms bid on capacity and concession term, and bids are evaluated by a scoring rule designed by the auctioneer. We educe the optimal auction mechanism by analyzing the incentive compatibility. In addition, we find that the optimal capacity is chosen independently...
Based on the latest research of neo-institutional economics, the frontier of corporate governance is extended, and the concept of ldquoventure capital governancerdquo is brought forward. Game theory is applied systemically in this paper to discuss all stages of venture capital governance. Especially, we analyze the aspect of participation in the management of venture business by means of game theory...
In order to reduce error following the improper model chosen to forecast the exchange rate by means of the traditional statistics, the continuous time Markov process is applied to forecast the short time exchange rate, which can describe the frequently fluctuation of exchange rate accurately. Time interval between two state transitions is regarded as a stochastic variable. By the aid of the transition...
Because of the current coexistence of two economy systems in China, namely planned economy system and market economy system, the electricity price is restricted. Considering only one economy system, the prevailing methods to calculate the profits of two parties, coal industry and electricity industry, are not applicable in China. Based on Nash equilibrium, a synchronous reaction model is established...
In the market economy, the cost of purchasing is one of the factors affecting the profit, so apply the theory of ldquodominant strategyrdquo to the process of purchasing, the decision-makers can control the daily transaction of purchasing more smoothly, and thus to realize the purpose of controlling and reducing cost. Practice shows this model is fairly reasonable and scientific especially applying...
Based on the theory of core competence, the paper analyzes construction enterprise's core competence from the perspective of knowledge capital. It establishes evaluation index system of construction enterprise's core competence, and then uses BP neural network to set the model of calculating construction enterprise's core competence. This model avoids subjectivity and uncertainty brought about by...
Urbanization has brought great challenges to the sustainable development of cities, especially in developing countries. Simulation of urban expansion thus captures increasing interests in research. SLEUTH model, a cellular automata-based dynamic model, is a powerful tool for simulating complex urban expansion and description of urban spatial dynamics. For further study of the dynamics change of urban...
In this paper we present a model of the formation and evolution of innovation network in an oligopolistic industry. A series of theoretical analysis of knowledge characteristics and simulation analysis of the weighted efficient have been studied. The results indicate that there exists the optimal relative knowledge distance and the codified extent of knowledge for collaboration. Moreover the weighted...
Along with increasing credit cards and growing trade volume in China, credit card fraud rises sharply. How to enhance the detection and prevention of credit card fraud becomes the focus of risk control of banks. This paper proposes a credit card fraud detection model using outlier detection based on distance sum according to the infrequency and unconventionality of fraud in credit card transaction...
The massive amount of visual inputs could easily go beyond the systempsilas computational limit. Visual attention provides an efficient way to discard the trivial inputs and achieve good performance. In this paper we develop a unified and consistent theoretical framework for the visual attention and inference with Bayesian decision theory. A visual attention scheme is simulated with an artificial...
As rapid development of economy and people's gradually great attention to energy environmental problems, more and more researchers have started researching the relationship between economy, energy and environment, we urgently need methods and models to solve the disagreement between them, and so 3E-based forecast and early-warning models began to emerge, and develop towards high-precision and comprehensive...
The paper discussed the optimum uses of water resource in a city based on social-economic-environmental (SEE) complex system by applying system dynamic model, which fully considered the interactions and interrelations amongst each element in the SEE complex system. The SD model can be used to estimate the overall development trends based on the current development status, and then relevant information...
The traditional group decision-making method mostly is static aggregation method which scientifically defines the decision weighted vector of each decision makers. In fact, the group decision making convergence is always a dynamic process. The preferences of decision maker are dynamic changing in this process, it is more realistic to apply the dynamic model to consider the consistence convergence...
With the development and advancement of reverse logistics concepts and practice, the evaluation and selection of vendors or partners for the specific function of reverse logistics support becomes more important. This paper firstly analyses the framework of selecting a third-party reverse logistics provider. Next, this paper presents a set of evaluation index system for choosing a third-party reverse...
A novel gene regulatory network model via the fuzzy logic is proposed. Fuzzy logic can effectively model gene regulation and interaction to accurately reflect the underlying biology. By judging genes expression level on the fuzzy rule, Fuzzy Boolean network (FBN) makes it possible to handle simultaneously the randomness and fuzziness of biological phenomena.
This paper states the necessity of establishing the economic evaluation system for safety resources in traffic enterprises systematically. The author gives the connotations of the proposed new economic evaluation system in traffic enterprises. The proposed evaluation system for safety resources can be used in all units with possible traffic accidents for estimating and reflecting the economic effectiveness...
This paper proposes a cooperation mechanism among seller agents and builds a model based on multi-agent system. In the model, a manger agent has been set to watch activities of other agents. It will encourage the cooperative sellers and punish the non-cooperative seller agents by adjust the sellerpsilas reputation in the repository. With this mechanism, a seller would complete the trade with the buyer...
In order to satisfy the Chinese enterprisespsila demand for the import of hi-tech equipment and reduction of costs during the import process, we need to construct an electronic alliance import platform for hi-tech equipment. This article attempts to apply the advantages of a large-scale electronic purchase platform for hi-tech equipment through the implementation of an "online reverse auction"...
Taking M2, the broad money supply, as the index of the level of liquidity and M2/GDP as the index of the surplus of liquidity, the paper examines systematically the long-term and dynamic relationship among the price, the level of liquidity and the surplus of liquidity. The results suggest that it is the surplus of liquidity instead of the level of liquidity that influences the fuel oil future. The...
