The aim of the work is to review and analyze the ideas and possibilities of modeling social welfare optimization based on the essential premises of neoclassical schools on consumer choice optimization. The work explains current and often controversial conceptions of basic postulates of economic welfare. It deals with the problems of defining the functions of social welfare, conceptions about the principles...
Field-programmable gate arrays (FPGAs) can provide an efficient programmable resource for implementing hardware-based spiking neural networks (SNN). In this paper we present a hardware-software design that makes it possible to simulate large-scale (2 million neurons) biologically plausible SNNs on an FPGA-based system. We have chosen three SNN models from the various models available in the literature,...
Taking talents policy of Shanghai government for example and basing on analysis of research of policy affectees, we setup index structure of three dimensions. These three dimensions are talent increase, talent centralization and talent efficiency. We measured talents policy of Shanghai from year 2001 to 2006 with Fuzzy Optimization Methodology Model. The effect of talent policy, trend characteristic...
The ecological-economic system of resource-dependent cities is compound system composed by the ecological system and economic system through certain technical means, environmental media and the process of human labor. It includes energy, material and information transmission. In order to maximize the value of the entire system and achieve the sustainable development of ecological-economic systems,...
Under the analysis of the present situation of urban roads at home and abroad, the paper reviews the development of tripper guiding information system, traffic-flow distribution model and route choice model. Then it has three multi-attribute decision-making model based on the influence factors of tripper route choice and uncertainty theories, in order to analyze the decision-making process of tripper...
In order to optimize the capacity of farmers' income persistently increasing, in this paper we analyze 8 factors affecting farmers' income increasing using PLS model based on the statistical data of Heilongjiang reclamation from 2000 to 2008. The study shows that wage incomes, agricultural subsidy and tax reducing still account for a great proportion of farmers' net incomes, but the level of agricultural...
At first, based on the thought over properly and the modern market competition, the flexible development of Circular Economy has been advocated as a new model of economy development. This development model can solve the externality problems better which have not been solved under traditional model. Then, in this paper, the"3+3"model of the flexible development of Circular Economy has been...
This paper focuses on the establishment of storage management models for permissible shortage and comparison between stock management systems with and without shortage. Through the comparison a relevant optimization strategy is brought up. Furthermore, this paper reveals that the supply chain system could run more efficiently with an establishment of a permissible shortage model in VMI pattern under...
For coal transportation in the shunting and winch system PID tuning is proposed adaptive genetic algorithm for parameter optimization of PID control, the adaptive line genetic algorithm combined with PID control technology, simulation achieved by shunting and winch system in the coal application, simulation results show that the online adaptive genetic algorithm for online optimization of PID parameters...
Irreversible investments with largest outlay made with incomplete information are the mainstay of the oilfield development. Real Options Analysis (ROA) is a useful tool for making investment decisions under market uncertainty. Normal information generates continuous mean-reverting process for oil prices, whereas random abnormal information generates discrete jumps of random size. We evaluate an oilfield...
By mapping the pump and the injector of 16V265H diesel engine, it comes to the conclusion of the structural parameters of the fuel injection system for electronic control unit pump. GT-Fuel is used to establish and perform the simulation model of fuel injection system for 16V265H diesel engine. Compared with that of local locomotive fuel injection system, the performance curve of 16V265H diesel engine...
According to economic ideas of Gary s. Becker, this paper builds the decision-making model of rural highway scales from the perspective of farmers under funds constraint, and gets the equilibrium condition of rural highways scales. Then with the figure analysis, the paper discusses impact mechanism of the several factors such as the financial structure of rural highway, rural urbanization, rural economic...
The paper makes analysis of the optimal currency composition of international reserves based on Markowitz mean-variance model using Monte Carlo simulation for solution. We calculate US dollar and Euro as the two major reserve currencies for 2007 through 2009, which is also the financial crisis stage. The model suggests to decrease US dollar in late 2007 and to increase US dollar in mid 2008. Our findings...
Most EOL electronic products come from industrial by-products and consumer goods as solid waste. Recycling the EOL electronic products is a complex and long term process. This paper focuses on the location and routing problem of electronic products recycling center. Firstly this paper applies AHP method to select the locations of electronic products recycling centers, and sort various elements by...
Because that transport links are not being considered enough in the existing decision making optimization model of manufacturers' order fulfillment, linear optimization model of manufacturers' order fulfillment is built according to factors as transporter, transport mode, type of line, model, and transportation of goods, transport origin and termination which have combined effects to transportation...
In this paper, we consider fuzzy variable weight combining forecasting which based on optimal combining forecasting and integrate those two modeling methods. Studies show that: optimal combining forecasting combines forecasting methods in a period of time and makes forecast through fixing the weight of forecasting methods that in the combination. But it does not consider that the weight will vary...
Environmental impact assessment has an important influence on project decision. Based on the fuzzy matter element theory and information entropy theory, entropy fuzzy matter-element model has been established, which is used to evaluate the good or bad of schemes. Taking scheme selection of highway as an example, the evaluation results show that the model can effectively eliminate the impact of man-made...
Aimed at the research on freeway detection algorithm has great significance for improving efficiency and effectiveness of freeway traffic management, this paper based on the freeway traffic flow's characteristics, in accordance with the incident detection's basic principle, researches on freeway incident detection based on Support Vector Machine (SVM). This paper designs four different simulation...
Refined Oil demand has great influence on the planning, operation and control of Refined Oil systems. A combined forecasting model based on the principle of gray theories was put forward to optimize Refined Oil demand forecasting models. The example shows that combined gray forecasting model can overcome the disadvantages of individual model, raise the precision.
Take a research in depth on the modeling problem of service path selection based on SON. Firstly, the optimal model is built with the optimal goal of balanced loading and with the functional constraints of users for composed service and multi-QoS constraints. Then the layered method and improved Ant algorithm are adopted to solve this problem. Finally, a simulated emulation is made to the algorithm,...
