This paper aims to compare three models in terms of development policies, development potentials and operational mechanism by evaluating, identifying and choosing the best one to meet the needs of tourism development and management in the nonoptimal tourism districts (NTDs). The methods of Participatory Rural Tourism Appraisal and Analytic Hierarchy Process are employed to collect the necessary data...
In this paper, the city input-output efficiency analysis which includes electric power input has been done based on the extension models of DEA to Chinapsilas typical cities. At first, it established index system of comprehensive evaluation of city efficiency, and did input-output-effectiveness evaluation which include electric power input for China's 23 cities in 2006 and sorted by the urban development...
For a three-echelon stochastic inventory system in the supply chain, it is difficult to get optimal inventory control policies by analytical methods. The paper sets up an optimization model, which is built on the basis of the discrete event system simulation theory. The simulation-based optimization method is used to solve the problem by combining the simulation model and the particle swarm optimization...
Regional brands are the senior stage of industrial cluster development as well as the strategic choice for elevating the competitiveness of industrial clusters. The public characteristics of regional brands contribute to the existence of "prisonerpsilas dilemma" in constructing regional brands and the key to the problem is local governments. This paper analyzes the two models in government...
The theory of quadratic variation suggests that, realized volatility is an unbiased and highly efficient estimator of return volatility under suitable conditions. In this article, we compare the realized logarithmic volatilities models VAR-RV and AR-RV computed from high-frequency intra-period data with the traditional daily return evaluation models VAR-R and Daily-GARCH in China A-stock market. The...
Public service is a special mission, which is to resolve public issues involved the whole community. However, given the goals of building a harmonious society evidence shows that investment on public service in China is still insufficient. This article explores the incentive of local government on public service. Using game-theoretic framework this paper analyzes the possible strategies and payoffs...
In order to study the effects of the contract coordination in the supply chain, the complex adaptive system (CAS), Agent model-building and supply chain theories were introduced, and the competitive rules and assumption conditions of simulation of the corporations in the supply chain were described. Then competitive environment of the supply chain was constructed on the Swarm simulation platform,...
This paper introduced the conjectured supply function equilibrium based model in order to construct the company's strategy model under the incomplete information. It can be used to apply in the market with inelastic electricity demand and it is more suitable to evaluate potential market power existed in real electricity market. On the basis of supply function equilibrium theory, it gives out the optimized...
There are usually three methods for supplier slecetion, they have their own characteristics and are suitable for different environmental requirements. In real economic activity, supplier selection usually take place in the environment with insufficient information, the evaluation indicators of which show both the quantitative and qualitative characteristics. Grey system theory solved the evaluation...
The paper improved the evaluation model of real estate project risk which based on Monte Carlo simulation technology. That is use three point which are maximum possible value, minimum possible value and the most possible value to estimate the risk variable. Using AHP method, variable weight of delivered and extended risk to determine the weight of each risk factor in the model objectively, and verifying...
In order to implement the multiple factors and multi-target assessment of real estate investment risk, a model of real estate investment risk evaluation based on fuzzy DEA method was put forward by using the relatively effective evaluation characteristic of Data Envelopment Analysis (DEA). And the feasibility of this method was verified through an example. This study offers a more rational basis for...
