In order to monitor the promoting effect of science and technology advancement on traditional industry upgrading, the logical structure of science and technology advancement reflecting traditional industry upgrading has been analyzed, and on the base of this, an evaluation index system has been proposed from perspectives of science and technology base, science and technology investment, science and...
Based on the data covering from 2003 to 2009 of finance expenditure referring to social security individually province of china, this paper unfolds on the efficiency comparison of finance expenditure using DEA-Malmquist index decomposition method to analyze empirically the differences existing between provinces and economic area. And we find that the efficiency at whole level is low than that expected...
The key factors which affect urban innovation environment were analyzed. On the basis of this, urban innovation environment evaluation indicator system of Hebei province was built. According to indicators data, urban innovation environment of Hebei province since the implementation of "great changes within three years" policy was evaluated by using multi-level fuzzy comprehensive evaluation...
The paper focuses on the study of environmental effects that electric vehicle might cause if they were connected to the distribution grid. A comprehensive evaluation index system is proposed in a quantitative way to describe the environmental effects, such as the pollutant reduction validity and greenhouse gas reduction validity. In order to ensure the economical efficiency of the system, the comprehensive...
Restructuring has changed purpose of generation expansion planning (GEP) from being cost-minimization to profit-maximization. In this paper, we introduce a new formulation for objective function of generating companies (GENCOs) GEP problem in pool electricity market which includes the revenues of energy and capacity reserve markets and costs of fuel, investment, O&M, outage and emission tax. Moreover,...
This paper presents the solutions adopted by Red Eléctrica de España (REE) in its software, E-LOLA, developed with the main purpose of calculating the probabilistic generation adequacy indices LOLE — Loss Of Load Expectation — and EDNS — Expected Demand Not Supplied — for the 10 Spanish isolated electric systems, making it possible to assess system adequacy through a non-deterministic approach. Based...
A major element of the 3rd EU energy package is the mandatory entry-exit tariff systems that shall be adopted to the transmission network access. There is a huge consensus around decoupled entry-exit tariff systems, because they can be more cost reflective, avoid cross subsidies between network users, facilitate gas trade and can provide signals for the location of gas injections or off-takes. The...
Photovoltaic(PV) power generation is one of the important ways to ensure that our country's energy security and realize the sustainable development of energy, but carrying on the investment risk assessment has become the focus of the difficulty and risk decision. Firstly this paper established its risk evaluation index system according to PV power project investment risk characteristics, and then...
This paper presents a methodology for transmission expansion planning using AC optimal power flow. A multi-objective framework has been considered in which three objectives are represented. The objectives are to minimize the investment cost (IC), minimize the operation cost (OC) and also to minimize the power losses (PL). The augmented ε-constraint method was used so as to solve the proposed multi-objective...
Agricultural technicians is the direct impetus of agricultural economy. In order to establish the investment mechanism for agriculture technicians in Guangdong Province, it's important to maximum the efficiency. Based on the DEA ( Data Envelopment Analysis ) model, this paper chooses the reasonable input indexes for agricultural technicians and output indexes for the economic benefit, analyzes the...
Corporate social responsibility (CSR) disclosure issues have been extensively discussed in past studies. In Malaysia studies that examine the factors affecting CSR disclosure by the company using the Resource-Based View (RBV) theory are still scarce. This study provides an insight into the factors affecting CSR disclosure of the companies in the context of RBV. Using CSR disclosure indeces of 150...
It is important to choose the voltage level of the mid-voltage distribution network objectively and accurately. An integrated model to choose the voltage level of the mid-voltage distribution network was proposed in this paper, in which analytical hierarchy process (AHP) comprehensive evaluation method to conduct a comprehensive evaluation was introduced. The model includes 5 indexs, such as economy,...
To speed up the construction of urban distribution network investment, a good way is to improve the reliability of grid power supply and the level of electric terminal safety. Electric power system is an organic whole, while urban distribution network has a large-scale investment. Under the constraint of total amount of investment, how to arrange the proportion of the investment between different...
This paper develops a new version of the so-called Simultaneous Long-Short (SLS) linear feedback stock trading controller for a class of idealized markets characterized by continuously differentiable stock prices. The two salient features of our new controller are as follows: First, all trading gains are appropriately discounted to account for “opportunity costs” associated with an alternative investment...
In order to solve the existing problems for the site selection of the distribution type logistics park, the impact factor for the site selection of the distribution type logistics park is analyzed and the evaluation index system for site selection decision of the distribution type logistics park is established in this paper. Grey correlation analysis associated with TOPSIS (Technique for Order Preference...
The investment decision-making problem, which makes it possible to distribute capital among real and portfolio investments, is presented. The investment decision-making method under uncertainty is proposed for solving the problem.
Investors have to deal with an increasing amount of information in order to make beneficial investment decisions. Thus, text mining is often applied to support the decision-making process by predicting the stock price impact of financial news. Recent research has shown that there exists a relation between news article sentiment and stock prices. However, this is not considered by previous text mining...
This paper proposes a methodology to consider the effects of the integration of DG on planning. Since DG has potential to defer investments in networks, the impact of DG on grid capacity is evaluated. A multi-objective optimization tool based on the meta-heuristic MEPSO is used, supporting an alternative approach to exploiting the Pareto front features. Tests were performed in distinct conditions...
Revising the basic concept of transport corridor, it wound introduce its theory evidence for the network planning project. By analyzing the key issues affecting the shape and framework of transport corridor, five qualitative indices was put forward with each one's detail reference. Then seven groups of indices were found out with each formula by analyzing which one rational transport system should...
