In recent years, road transport models have developed for better estimation of road traffic emissions with higher and higher temporal and spatial resolution, to be used as a tool in air quality management for the better living. Road transport related emission models are becoming more and more complex. In this paper, the key research question is how the improvement in modelling influences the results?...
Proposes an approach to assessing the state of plant species (based on an example of assessing the state of large-leaved linden) in urban environment on the basis of fuzzy information from a group of experts. Formalization of the expert information is carried out on the basis of complete orthogonal semantic spaces. The proposed approach allows to avoid mistakes in the assessment of a single expert...
Modern Russian management model is a mixture management methods based on post-Soviet economic reality and Western best practices. Entering the global economy in the 90th Russia was forced to adopt foreign management models suitable for new market reality. Nevertheless foreign management models could not be copied in pure forms. The authors conducted the analysis of the Generation theory (baby boomers,...
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...
The paper presents a comparative analysis between the Multicore and the Grid execution of SWAT hydrological model. We try to emphasize the advantages brought by the Grid infrastructure, especially for large scale applications which require large number of executions and huge data resources. We use as a case study a large scale hydrological model, built using the Arc SWAT program, which covers the...
This paper carries out a comparative analysis on three innovation entities of the national innovative system (namely, enterprise, university and government research institute) and evaluates their R&D efficiency from 1998-2006, by using the Data Envelopment Analysis method. The empirical results show that the R&D efficiency of enterprises is relatively invalid given the high R&D input,...
Mode of operation of tourism enterprises by the local development level of e-commerce, enterprise's own characteristics, and so on. Tourism e-commerce in China-US business model is far greater than the differences that exist in the service function of the existing differences. In this paper, from a tourist site and a comprehensive Web site navigation, and strategic collaboration between the co-operation...
The Toyota Production System (TPS) has long touted the workforce management technique of continual improvement in the face of economic downturns. This is counter to a more general approach of short-term and long-term layoffs in manufacturing, associated with more traditionally managed companies. This paper builds a quantitative decision tool for choosing between layoffs and continual process-based...
This paper studies the replenishment problem in a single item, multi-supplier environment. A cost optimal model is presented. A comparative analysis with singe supplier model showed the difference in two conditions. An extended model based on model in MTP is proposed when considering the time and production capability constraints in MTO and shows the management issues in organizing MTO supply chain.
Exchange rates float with non-linear dependence and long-term memory characters, so we choose the neural network tool to forecast it. Based on the previous research work, we use two groups of data at different time-intervals to make forecasting experiments with homogenous neural network model and heterogeneous neural network model. According to the results of the experiments, we make a comparative...
Faced with increasing congestion on urban roads, authorities need better real-time traffic information to manage traffic. Kalman filters are efficient algorithms that can be adapted to track vehicles in urban traffic given noisy sensor data. A Kalman filter process model that approximates dynamic vehicle behaviour is a reusable subsystem for modelling the dynamics of a multi-vehicle traffic system...
Regional economic system includes the industry structure and geographical subsystems. Yangtze River Delta is the most sparkly area in China. Since 1978, the implementation of reform and open policy, majority cities of the area has developed into the stage of industrialization period. With the statistical data of Yangtze River Delta 1978-2007, this paper uses correlation analysis, comparative analysis...
Fixed-mobile substitution is an irresistible trend throughout the world. However in the process of FMS, the patterns of fixed to mobile substitution varies with time and are quite different from one place to the other. This paper set up regression models to explore the relationship between the demand for fixed and for mobile, based on the fixed line penetration and mobile penetration from four groups...
Motivating is a very important part in the management of sports team, effective motivating will make sports management more actively. The author elaborated the current situation of motivation in the management of Chinese and foreign sports teams, and analyzed the main traits of current research, and did some comparative analysis on related issues, which conducted to make effective motivating play...
In stock markets, the price is fluctuating around its average value with the time being. One of the volatilities is the variance heteroscedasticity. It is found that auto-regressive conditional heteroscedasticity (ARCH) model provides an alternative approach for the simulation of stock heteroscedasticity. In this paper, the application of ARCH and its modified models is presented for the risk analysis...
