Investment models for decision making on unconventional hydrocarbon resource development in Europe must be based on realistic estimates of well productivity, gas price projections and reliable data concerning the costs of the project. In this analysis we assess the economic feasibility of three different investments projects in coal bed methane production located in three European regions: Cheshire...
The increasing penetration of renewable energy sources and the electrification of heat and transport sectors in the UK have created business opportunities for flexible technologies, such as battery energy storage (BES). However, BES investments are still not well understood due to a wide range and debatable technology costs that may undermine its business case. In this context, this paper establishes...
This paper proposes a methodology for modeling mothballing decisions in order to better study the different strategies adopted by power plants owners and their impact on power systems (in particular generation adequacy). A system dynamic approach is adopted to build a model which represents investment, mothballing and shutdown decisions in an energy-only market. The results obtained with the proposed...
Construction of ecological port has become an important direction of port development. Research on evaluation and prediction of evolution of port ecological carrying capacity trend can provide available and reliable method for ecological port construction. A system dynamics (SD) model for port ecological carrying capacity considering characteristics of port ecosystem is built in this paper, based...
Energy is a commodity used worldwide, representing a vital input for social and economic development. Due to continuous growth, energy demand has increased. Solutions have been proposed in order to satisfy the increase in demand, often implying the increase of capacity of the power mix. Meanwhile, current issues concerning climate change and fossil fuels depletion has moved attention towards cleaner...
Taking the factor of customer switching into count, we analyze duopoly models in which both start-ups and established firms consider the competitive investment in R&D when they enter the new market. Firms make a decision on investment will influence the customer switching. The firms with investment may attract new customers from other firms which does not invest and then maintain more market share...
Farmers' behavior of cultivated land protection in karst region affects ecological safety of Yangtze and Pearl River. Based on survey data collected from 399 farmers' investigation in Guizhou Province, the Logistic-ISM model was used to analyze the influencing factors. It shows that the distance between home and town, voluntary technique, numbers of contact information, numbers of exchange information...
Historically, discrete-event process simulation was used first and most often to the study and benefit of manufacturing processes. Its domains of use have steadily expanded during approximately the last half-century to include supply chain operations, computer networks, health care, and retail service. All of these economic domains exhibit intense competitiveness. The application of simulation presented...
Automated trading has become very popular in electronic markets, such as stock market. The design and evaluation of trading agents are not trivial due to the complexity and dynamics of this scenario. Using an actual and reliable dataset from the Brazilian Stock Exchange, and aiming to support the Market Making process in High-Frequency Trading, in this work we design and evaluate some models of automated...
The purpose of the spare parts inventory is used to maintain the normal operation of the equipment, the best metric to measure the merits of the spare parts inventory levels is the use of security equipment. Therefore, Under the constraint of the total supply of spare parts cost, based on spare parts of marginal utility analysis, here propose maintenance waiting time as the objective function of optimization...
In order to promote the application value and instruction significance of “structural Keynesian investment multiplier” (abbreviated as SKIM), this paper takes environment consumption and environment input into the second-stage input-output table. It meanwhile proposes a concrete plan of compiling a “second-stage input-output table that incorporates environment factor”, and based on this designs a...
As the United Arab Emirates is diversifying its energy sources, it is increasingly looking towards solar photovoltaic technology as a viable option. A key factor in promoting this option is the capability to forecast financial viability of solar projects. This paper uses stochastic analysis instead of deterministic analysis and applies it on potential UAE solar power projects to obtain a wider understanding...
This paper studied the relationship between industrial elements input and cluster-benefit, took Shandong province's and Zhejiang province's textile industry as an example, analyzed the data from 2000-2007 of the two provinces with scale sensitivity model. We found that investment and benefit in Zhejiang's textile industry are inconsistent, the element affects most is unit value of liquid assets. Further...
One of the most important activities of Human Resources departments is the active management of the hiring process. The purpose of this study is to observe cost-benefit analysis methods about the calculation of additional contribution that the hiring process would create and to put into a practice. For the cost-benefit analysis of the hiring process, Taylor-Russell, Naylor-Shine, Brogden-Cronbach-Gleser...
The industry investment emphasizes how the role of the investment may effect the structure of the industry and whether the investment could stimulate the industry for further development. Taking the regional productivity and relative advantage into consideration and using Polynomial distributed lags model, the dynamic correlation between gross fixed assets investment and GDP of the three industries...
Stock market plays a vital role in country's economy and financial system. It has many impacts on the economy like raising capital for businesses, aiding company growth, corporate governance, mobilizing savings for the investment, reallocation of wealth, government capital-raising for development. In stock market the investors are normally dependent on brokers for appropriate selection of shares for...
Open-end funds and Closed-end funds are two different operating mode for the fund. In this paper, it calculate the risk of the stock fund and compare the average VaR between the Open-end funds and Closed-end funds. As the Fund's day yield is non-normal state of "spike-thick tail" of the distribution characteristics, we use GARCH models to calculate the value of the fund's VaR. Empirical...
Prisoner's Dilemma, which is a basic model adopted by the vast majority of co-evolution researchers, not only is a classic paradigm for studying co-evolution but also is a classic paradigm of modern business management for researching the enterprises, between which there is competition and cooperation. In this paper, a dynamic model of spatial continuous Prisoner's Dilemma (CPD) will be suggested,...
Based on the relevant data in the year of 1983-2008,the paper utilizes Co-integration Test and Error Correction Model to inspect the influencing factors on FDI Location Choice in China. With a such research, the paper comes to the conclusion, that is,there is a long co-integration relation among them,fixed asset investment,R, former accumulated foreign capital amount, loan balance of financial corporation...
Considering the impact of the objective environment on the economic system, this article introduces gray elements to a dynamic input-output model which is based on variable structure control, and proposes the methods of determining the important parameters of the model. This model can reveal the relationship between propensity to consume, propensity to invest, the structure of consumption and investment,...
