Reactive power optimization has been a hard problem for years. However, the existed optimization algorithms are usually complex in calculation and not obvious in physical meaning. To study a simple and effective method for reactive power optimization, this paper puts forward a concept of optimal reactive load, and proposes a method called power circle method. With power circles, this paper presents...
Rural labor force transfer plays a very important role in narrowing urban-rural income gap and promoting regional economic growth, and analyzing and exploring constraints influencing rural labor force transfer is the key in realizing smooth and reasonable surplus rural labor force transfer. On the basis of new economic migration theory, this thesis tries to quantitatively analyze factors influencing...
Resources management is the most important part of the cloud computing. This paper introduces the lifecycle of cloud bank which based on existing cloud bank model and present the proper pricing strategy. It was according to the features of cloud bank in different periods. The purpose of this paper is to provide an automatic updating mechanism to pricing the cloud resources and maximizing the benefit...
Aiming at out of date of cost management in hospital, which is an obstacle for the hospital management and schedule of medical resources, activity based costing model was proposed. Resource was assigned to activity center by using resource driver and then allotted from activity into cost objects according to activity driver; Lastly B/S four-tier software prototype based on J2EE was developed, and...
After the global financial crisis, the issue of mineral resources has become a significant problem which constraints on China's economic growth. China's economic growth must not be based on high consumption of resources. Resource constraints caused by excessive consumption of resources, will become the major difficulties in China's economic industrialization and modernization development process....
Mineral resource is the material basis in the progress of human society and economic development, as well as the essential element in the sustainable development. The non-renewability and the sustainability of the development of mineral recourse require us to minimize energy consumption and achieve the economic maximization, which allows the resource-based circular economy as the strategic choice...
With the development of society, the human capacity to transform nature gradually increases, as which environmental pollution and ecological destruction have occurred. The faster pace economy developed, the larger scales economy expanded, and the stock of resources dropped at an alarming rate. Environmental issues are posing a threat to human beings in the future. In this paper, we study the issues...
The introduction of economics in resource scheduling is an effective solution in grid. In this paper,based on the banking model as an agent, it provides the analysis and guidance for all participants from the perspective of the overall activities in the grid. The Deadline and Budget Constrained (DBC)-based iterative algorithm can update the prices through analyzing the history of the used resource...
Renewable energy has stronger relationship with human development than ever. According to extensive studies on existed stand alone wind and photovoltaic (PV) hybrid power system, a novel method of optimum sizing was presented to obtain proper combination of wind and solar generation and effectively analyzed economic performance. Annual total cost model was proposed and genetic algorithm (GA) was used...
