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...
There are presented two recent applications of special semirings. There is introduced an innovative concept in modelling operations of container quay cranes based on pseudo-analysis in the form of maxplus semiring. In social sciences the ordering on a semiring of monotone doubly stochastic matrices in Shorrocks' sense is investigated. It is identified a class of an equilibrium index of mobility that...
A robust semi-supervised method using the mode filter has been presented for learning with partially-labeled training data including label errors. The mode filter has been originally developed for smoothing images contaminated with impulsive noises. However it needs nonlinear optimization which is usually solved with iterative methods. In this paper, we propose a direct solution method with full search...
H.264, MPEG-4 Part 10, is the latest digital video coding standard that achieves very high data compression by using several new coding features. One of the new feature is variable block sizes for inter frame coding to increase compression efficiency. However, to achieve this, the H.264 encoder employs a complex mode decision technique based on rate-distortion optimization (RDO) that requires high...
Evolutionary algorithms are an important branch of soft computing, being able to provide approximate solutions to problems in a reasonable amount of time. The underlying principle can be realized in an almost unlimited number of ways. This paper presents four main variants of evolutionary algorithms, and a method of running them in a topology consisting of multiple populations. The resources given...
The heterogeneous fleet vehicle routing problem with time windows is a variant of the classical vehicle routing problem. This paper defines a mathematical model of this problem and proposes a variable neighborhood tabu search algorithm to solve it. The initial solution is obtained by GENIUS and the giant tour algorithm. Our algorithm employs a variable neighborhood mechanism to search the optimal...
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,...
With the increasing popularity and development of e-commerce and information technology, multi-attribute bilateral matching problem has been receiving more and more attention. In this paper, multi-attribute bilateral matching problem is discussed based on the consideration of stable matching. Concepts and definitions of multi-attribute bilateral stable matching are presented firstly, followed by the...
The paper has constructed the mathematical model on the storage location assignment in AS/RS, and then optimized and solved it, performed instance simulation design and analysis on the storage location assignment by means of Flexsim. Finally, we have concluded that the storage location assignment model after optimization would solve the storage location assignment problem in AS/RS effectively and...
This paper puts forth a model of the transportation and inventory integration and optimization problem based on system and optimal theory which we take into account the antinomy relationship of transportation and inventory and the antinomy relationship of inventory and stock-out in supply chain logistics system. We consider that the resources available and the total time of inventory and transportation...
Optimization of international transport chain may significantly contribute a successful outcome of international trade. The performance of various transport mode influences its selection. This paper analyses and compares the transport chain between China and Austria, aiming to identify the best practices and choose the optimal transport mode. Based on analyzing secondary data, the different transport...
The topology optimization of YKS5120B-3 NC gear shaper machine tool bed is completed based on ANSYS with the shape envelope of the whole tool bed as solution domain and the minimum static compliance as objective function. The optimal topology model of the tool bed is obtained. And then the tool bed model is reconstructed in Pro/E and re-tested by static and dynamic analysis in ANSAYS. The re-tested...
Energy model and its feature and the layer structure in iron and steel industry were described in detail. Energy balance and comprehensive optimization model was set up further with iron and steel industry production practice. The model analysis indicated that it was applicable to solve engineering problem. Energy input-output model was established with energy input-output table based on material...
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...
In this paper, the author converts inequality constrained optimization problem into equality constrained optimization problem by using slack variables. Then we construct a new multiplier penalty function using the penalty function who belongs to equality constraints and was raised by Bertskas in 1982.
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,...
Information-theoretic cost functions such as minimization of the error entropy (MEE) can extract more structure from the error signal, yielding better results in many realistic problems. However, adaptive filters (AFs) using MEE methods are more computationally intensive when compared to conventional, mean-squared error (MSE) methods employed in the well-known, least mean squares (LMS) algorithm....
Under the pressure of global financial crisis, enterprises tend to enhance ability of Supply Chain Management (SCM) and their own advantages can be developed in the competition. A decision making model of multi-product multi-stage supply chain consisted of single manufacturer and single supplier is proposed in this article. The model is proved to be superior and efficient through application example...
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...
Rail high-speed passenger lines (HSPL) have been developed rapidly in China; however, the traditional rail crew scheduling mode called responsible mode, in which crews are bundled with vehicles, is hard to adapt to the transit characteristic of HSPL. Moreover, the utilization of rail crew resources is commonly inefficient and the scheduling methods are generally behindhand. To reduce the pressure...
