When there's heavy traffic passing off-ramp of urban freeway and close to joint section, the intersection and the passage of the side road traffic will be influenced. In this paper, a coordinated control method based on the mixed logic dynamic(MLD) model will be introduced using bi-level programming genetic algorithm to coordinately control the off-ramp and the downstream intersection. In bi-level...
In the problem of optimal sensor deployment for satellite antenna reflector, to avoid the one-sidedness of single-objective criterion, in this paper, we adopt double-objectives criterion, which contains the largest orthogonality and the highest vibration energy of observed signal. The double-objectives criterion is converted to single-one criterion by mathematical transformation and Genetic Algorithm...
Scheduling for the flexible job-shop is very important in both fields of production management and combinatorial optimization. However, it is quite difficult to achieve an optimal solution to this problem with traditional optimization approaches owing to the high computational complexity. The combining of several optimization criteria induces additional complexity and new problems. Particle swarm...
An adaptive resource allocation scheme for QoS oriented OFDMA system, which schedules two different utility functions for the Real-time/Non Real-time traffic simultaneously, is proposed in this paper. Instead of partial consideration of uniform kinds of QoS, we introduce an updating ratio factor to schedule users of heterogeneous traffic. Due to the complex optimization objective, the general convex...
This paper aims at the optimizing design of regional coverage reconnaissance satellite constellation. Firstly, model of regional coverage satellite constellation is set up before the design is formulated into a multiple objectives optimization problem. Secondly, a nondominated sorting genetic algorithm (NSGA) and its improved version, elitist and fast nondominated genetic algorithm (NSGA-II), are...
