In order to enhance the level of public transport services, this paper presents a multi-agent model of public transport, including guidance and management of multi-agent. The authors set forth the role of public transport agents, to put forward the components of public transport multi-agents model, as well as the specific contents of guide agent components and management agent components; Finally,...
A new early warning method of the complex systems for real estate market is proposed in this paper. First, principle component analysis method is adopted, and 8 important indexes are screened from a great number of indices. Second, these 8 important indices are divided into 3 kinds which are called as antecedent, synchronous and delayed with the time-difference correlation analysis method. Third,...
The forecast of the demand for the highway transportation is extremely important theoretically and practically since the road is the national infrastructure. The original GM(1,1) models have been analyzed, and their shortcomings in the road forecast have been pointed out. Because sometimes the precision of grey model cannot meet the requirement of actual forecasting, a novel improved GM(1,1) model...
The present paper introduces fuzzy reasoning into the GMDH network to replace partial descriptions of the conventional GMDH network, i.e. the absolute binary quadratic polynomials. Drawing upon the GMDH network, the authors propose a fuzzy GMDH network, and apply it to traffic flow forecasting. Simulative results by computer show that the new network is valid.
Transportation mode selection lies in both goods and passenger transportation. However, the decision-making process is always influenced by many factors. The classical decision-making method has some subjective factors about sequencing the factors. The paper gives a reasonable sequencing method combining DEA with AHP. It is testified that the method is adaptive in the process of transportation mode...
In the multi-agents public traffic control system, the problem about being comfortable is very important. The challenge is to find solutions to achieve the objective minimized amount of vehicles in overload. This paper proposes a solution algorithm for keeping comfortable of public traffic based on grey disaster prediction through principled cooperation between agents that represent traffic command...
To determine the optimal investments on road network of comprehensive transportation system, a bi-level programming model for continuous network design problem was employed. At the upper level problem, planner makes investment decision in links and hubs of a comprehensive transportation system to minimize the total times costs plus investment costs and the external costs such as environment pollution,...
Ant colony algorithm (ACA), inspired by the food-searching behavior of ants, is an evolutionary algorithm and performs well in discrete optimization. In this paper, a new kind of general clustering algorithm based on ACA is presented according to the principle that how human do clustering and the action that how ants look for food. With this algorithm, we need not take some time to gain the initial...
On the basis of lacking the effective means to measure the human capital of entrepreneur, this paper comprehensively applies Grey system theory and AHP to put forward grey hierarchy model to evaluate the human capital of entrepreneur, which is simple in calculation and high in credibility.
Owing to the significance of urban water resources demand management, and in accordance with urban water demand with features of both growth and periodicity, an urban water resources supply and demand management dynamic optimal control model was constructed. On the basis of the prediction of urban water demand, the urban water demand could be satisfied through reasonable control of urban water supply...
This paper founds a new model of hierarchy synthetic evaluation of vc-backed enterprises based on the gray relation analysis, and presents a new method to determine the weights of the indices. This method can be used to avoid the subjective factors in valuation and get the satisfactory results.
The modeling and predicting for passenger flow of comprehensive transportation between cities are studied Passenger flow for different transportation mode is concerned with both social and economic characteristics of passengers, and also concerned with personal preference of every passenger. This is a modeling and predicting problem for complex systems. First, a 3-layer neural network is structured...
