Chinese cities are now at a stage of rapid development and the problems of transportation, environment and land use are increasingly serious. Urban rapid rail transit is wholly a convenient, fast, effective, low-carbon, environment-friendly urban infrastructure system, which providing an effective way for the sustainable development of urban transit and land use. In this paper, the effect mechanism...
Former research of transport reliability focuses on road network, few of which refer to the intersection traffic reliability in microcosmic level. The paper proposes the conception of traffic reliability based on which the supply-demand reciprocity is analyzed, and brings forward the methodology that the disabled condition should be differentiated according to distinct system functions. Aiming at...
Firstly the necessity of the design of signal coordination control system in urban main roads is presented , and the design thinking and process of the signal coordination control system is given, then according to the design thinking and process create a model of signal coordination control system in urban main road., and Qingyang Road of LAN Zhou City is taken for example, based on the survey data...
To find the risks in food supply chain and to take appropriate measures to guard against risks and increase capacity of food supply chain to resist risks. The paper established Logistic regression early-warning model to recognise magnitude of risks based on principal component analysis and Logistic regression analysis. An empirical analysis is carried out to test the model by take out some food enterprises...
For apparel enterprises, vendor selection is an important decision-making. A satisfied vendor may depend on an appropriate selection method. Vendor selection is a classic multi-objective decision-making problem and multi-objective assessment method is useful to solve it. In this paper, we proposed a new model which synthesizing AHP and DEA methods to evaluate the vendors for apparel enterprises. An...
3D model was established by analyzing the flow of ceramic paste in the screw channel. Set the boundary conditions on the premises of "only the barrel rotating", "only the screw rotating", "only the flight rotating" and "the screw root and flight rotating together" respectively, numerically simulated the paste flow with finite element analysis software ANSYS,...
This paper, which based on the assumption of product market demand price-dependent and random deviation, makes models respectively to discuss the optimal strategy in the cooperation and non-cooperation conditions between the supplier and the retailer, which is how to determine the most superior wholesale price of the suppliers optimal order quantity of the retailers and retail price. Suppliers, which...
This paper deals with chaos of nonlinear dynamical system of the Permanent Magnet Linear Synchronous Motors (PMLS -M),and a new chaotic simulation model is proposed by mathematical transformation. Under certain conditions,chaos of Permanent Magnet Linear Synchronous Motors appears by simulation,which provide an important research basis for the control and further analysis of chaotic behavior of Permanent...
A performance degradation prediction method for multi-unit system with insufficient measurement data is proposed by integrating data recovering model, hidden Markov model and support vector regression (SVR) model. The development of the model includes three main parts. Part one, a principal component analysis (PCA) model is build based on normal state. Part two, a hidden Markov model(HMM) is trained...
In order to solve the problem of that the initial investment of truck dispatching system is vast and how to quantify scientifically to analyze the technical factor of truck dispatching system. A truck real-time dispatching model was built based on two minimization dispatch criterion. The method of "Comparing different index setting Simulations Used by the Same Shift (CSUSS)" was put forward...
Leslie Lampor proposed the theory of Temporal Logic of Actions(TLA),which can express model program and logical rules in one language at the same time. Secure Electronic Transaction(SET) is an secure protocol for e-commerce, Based on the open network and paying with credit card. The agreement defines the whole process of the internet transactions. And it has a complete authentication. Based on the...
Cluster supply chain is the network of supply chains based on localization and integration in industrial cluster. It is often that multiple linear supply chains in the same cluster are interactive and need to collaborate with each other. This paper considers the inventory collaboration control across two linear and two-echelon supply chains with a third party logistics provider (TPL) . Based on the...
Most of the inventory models under delay in payments only considered the relationship between the manufacturer and the retailer. However, in practice, the retailer also provides the customer with the credit period to stimulate demand. A three-echelon supply chain system with one manufacturer, one retailer and one customer is presented in this paper. From the perspective of the retailer, fuzzy inventory...
The traditional DEA model didn't consider the importance of input and output indicators when it analyzed the relative effectiveness of each DMU. In fact, the importance of the various indicators is greatly different for the demand side in terms of logistics services. This paper chooses the various input and output indicators by AHP, Especially considers the difference of indicators for demand-side...
During the first decade of this century, the online games are developed rapidly in China. But the virtual items transaction problems hinder the development of online games. Traditional trading models cannot meet the demand of both security and convenience at the same time. In order to improve the traditional transaction models, this paper presents a more secure transaction platform by embedding a...
Nowadays, Rail-guided Vehicle (RGV) has been widely used in the logistics system, and some large storage systems often use double RGV to operation simultaneously. Then RGV operation policy and influence on the efficiency of the logistics system become interesting problems to designers. This article describes the Path-divided Mode and the Path-integrated Mode of operating policy of double RGV transportation...
Competitiveness measurement of ports should consider all internal and external factors. In this paper, we use a number of quantitative measurement indicators to evaluate the actual situation of Shenzhen port. By using factor analysis model, a small number of common factors are extracted to represent the large number of measurement indicators. Furthermore, this paper computes the evaluation scores...
In recent years, listed commercial banks of China come into the market in succession, whose competitive levels are getting more and more attention from academia and practice. This paper establishes evaluating indicator system of the commercial banks, from the capacity of real competitiveness and sustainable development of banks. The data come from the financial statements of five listed commercial...
Construction of underground natural gas storage is a large, complex, with multi-objective nature of the projects. Vague Sets Based on Underground Gas Storage solution design are optimized. Examples show that it is convenient and feasible. Proposed single-value data into the data of the formula Vague, Vague sets introduce new similarity measures between the new formula, these two types of formula as...
This paper designs and makes a questionnaire based on a deep interview, and analyzes those data by SPSS11.5, then constructs recognition model of the network learning by EFA, on basis of these, it tests the validity of recognition factors and the reliability of recognition model by CFA empirical study and Cronbach'a coefficient. Results show that knowledge acquisition, knowledge absorption and knowledge...
