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...
In order to improve the efficiency of the expressway and solve the problem of traffic congestion, this paper introduces the HOV lanes, and a comprehensive evaluation model for HOV lanes was established with the analytic hierarchy process taking into account the facts such as the efficiency of transport operations, resources and environment, and economic and financial. Specific road section was selected...
This paper analyzed the logic structure of composite transportation system which was composed of car network, bus network and urban rail network, and represented the logical relation between each modal-sub-network by building 3D model. By analyzing the constituent structure of composite network, choosing attributes and analyzing travel impedances, the composite traffic system network was established,...
Accessibility is taken for the comprehensive and effective method for traffic network evaluation, and gradually is used in diversified domain, such as urban planning, traffic planning, spatial structure and regional economy development. GIS as a kind of new technology, it provides a more simple, accurate and effective tool for the computing of accessibility. Usually, the study of accessibility only...
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...
The viscous resistance calculation methods for trimarans were presented in this paper, as were developed out based on the thin and thick boundary layer theories, with the integral calculation procedure built in the streamline coordinate system; and the viscous resistance calculation of the monohull and trimaran were performed by present methods as calculation samples, the calculation results having...
Adaptive cruise control (ACC) system is a Driver assistant system, which can provide safe and comfortable driving. Based on the analysis of ACC system, a parameter self-tuning fuzzy-PID algorithm is developed to design the ACC control strategy. According to the traffic condition, the parameters of PID controller are adapted on-line by fuzzy rule. The simulation results show that the parameter self-...
This paper makes a detailed analysis of purchasing management, pointing out the existing problems and optimizing the process, to improve the quality and reduce the cost of purchasing. Inventory management is also studied by elaborating the quantitative ordering method and its application in engineering; analyze the inventory cost control of construction enterprises with respect to supplier and inventory...
Transportation resources allocation of group enterprise is an important research issue. Based on the non-convex interval goal programming and the discrete resources ideology, this paper sets up three categories, eight basic models for the analysis of enterprise transportation resources allocation. These basic models could be modularly used in practice. Our research outcomes are consistent with the...
This paper studies customer's behavior in choosing services in a competitive service supply chain characterized by service congestion phenomena. Heterogenous customers choose services based on the utility maximization principle taking congestion into account. We use customer choice theory and infinite dimensional variational inequality to model the customer behavior and estimate service market share...
Contemporary industry trends and business practices, such as global sourcing, decentralized production, reduced number of suppliers etc., make supply chains more susceptible to disruptions which have caused severe domino effects in the past few years. This paper addresses a supply chain disruption problem with recovery from disruptions. Two types of producers are assumed to exist inside and outside...
This paper studies the interactive development between International Shipping Center and regional economy. Some econometric models are used to analyze the relationship, including binary linear regression, cointegration test, and Granger causality consequence test. Then a case study of Dalian International Shipping Center is put forward to verify the effectiveness of the models.
Belt conveyor is one of main electromechanical systems in the coal transport system, its safe operation plays an important role in the whole coal output systems. As the belt conveyors get longer, quicker and bulkier, the traditional static design method already can not satisfy the requirement of actual engineering. One of problems is that a huge peak belt tension induced by the starting and stopping...
When emergency occurs, a reasonable and efficient resource scheduling system is urgently needed to deal with influences caused by emergency. In regard to the scheduling problem of single one-time consumption resources in the emergency logistics system, this paper establishes a resource response decision model with the goal of minimum emergency response time, least saving points, highest reliability...
This article analyzed domestic and foreign contribution and fusion research actuality between informationization and advanced orbital transportation equipment manufacturing industry, introduced China emphatically about the informationization and the advanced orbital transportation equipment manufacturing industry policy development environment. First, the Informationization to advanced orbital transportation...
The paper analyzes the concept, elements and data structure of the multi-mode transportation network, proposes a polycentric hierarchy description model of the integrated transportation network, and discusses the construction method of multi-mode transportation network using GIS technology. The design of system function modules provides a visual edition platform to realize the construction of integrated...
This paper uses GMDH method to establish a prediction model to forecast the vehicles for business transport of Guangxi in China, since the original samples of the output value of transport & storage of Guangdong are less enough to be used with the traditional methods. Compared with traditional linear regression and artificial neural network, the predicted results show that GMDH method is an effective...
Public Transport Priority (PTP) is adopted as basic transport policy in many metropolitan cities, especially like Beijing, with great number of population and rapid urban economic development. This study mainly discusses how PTP measures affect travelers' behavior, what type and levels of PTP measures increase the acceptance of public travel modes, and how PTP measures take a positive effect in Beijing...
There are many problems in the layout of the railway freight stations, such as too many stations, the higher density of stations, and so on. So, it is necessary to adjust the layout of freight station and integrate the freight transport resources to raise the freight transport services level. According to the Sugarscape model and the analysis of advantages and disadvantages of Human Element model,...
Firstly, an air passenger capacity investigation at the capital international airport is made, and a composite forecasting model based on total air passenger capacity is established, in which multiple regression and ARIMA model are parallel connection and their forecast results are series connection with BP neural network. Secondly, according to the average growth rate of air passenger capacity, all...
