In the massive activities of cities, rush hour is short while traffic flow is great. Traffic flow is unbalanced on time and space. If the measure of traffic control is not right, the traffic is affected badly. In this paper, a bi-level programming model about traffic control measure is brought forward. In upper level, providing key member with high transportation service is first thought over, and...
The bi-level programming of regional logistics system in elastic demand was studied by using fuzzy c-means clustering. Game relations among the government, the owners of the logistics centers, and the clients were discussed by system analysis method. The synthetic evaluation indices of 17 characteristic vectors were established. The problem is equal to that of determining the membership values to...
A network design problem is formulated as a bi-level program generally. In the traffic system, on the one hand, guidance facilities are invested and built. On the other hand, travelers can choose their paths according to both guidance information and their experience. In this paper, based on the relationship above, the optimization plan is established. The objective function at the upper level is...
In the traffic system with flow guidance, travelers can choose their paths according to both guidance information and their experience. In this paper, based on the relationship between the effects of traffic guidance and the construction cost, the optimization plan is established as a bi-level program. The objective function at the upper level is defined as the total travel time on the network, plus...
The model of the multi-objective optimal allocation of water resources with government system of water rights is a bi-level programming model. The function of water trade price is difficult to determine, and some factors are interactive such as water price, coefficient of water-saving and objective function, whose relationships are rather complex, so that it is attractive to study the model solution...
The bi-level programming of regional logistics system was studied by using fuzzy c-means clustering. Game relations among the government, the owners of the logistics centers, and the clients were discussed by system analysis method. The synthetic evaluation indices of 17 characteristic vectors were established for clients to select the logistics centers and exchanging amount. The problem is equal...
