Improved Ant colony algorithm is applied to the dynamic evacuation route optimization (DERO) in this paper. The traditional ant colony algorithm is improved in term of the Tabu list and searching termination condition to simulate the process of human evacuation within a building. The route with the lowest risk is identified by risk analysis according to environmental changes. The method has significance...
A mathematic model for multi-objective bus route optimization based on the date of a bus corporation and limited conditions in the route network is developed on account of route optimization of bus dispatching. MAX-MIN Ant System is used to improve the global searching ability of ant colony algorithm and the improved algorithm is applied to solve the problem and its global optimization is obtained...
In this paper, the vehicle routing problem with time windows (VRPTW) was considered, and a mixed integer programming mathematic model of VRPTW was proposed in detail. Meantime, an improved ant colony algorithm (IACA) was proposed to overcome the shortcomings of premature convergence and slow convergence of conventional ant colony algorithm (ACA). The experiment results showed that the IACA can solve...
