| 摘 要： | 借鉴了微观经济学中供需作用机制与均衡原理,对交通系统中的均衡状态及其演化过程进行了分析.通过对启发式算法中的模拟退火过程加以分析,在一个OD对之间具有多条路线条件下,应用模拟退火算法分析了交通分配均衡模型,并设计了求解步骤,以Beckmann的用户均衡模型为例,编制Matlab程序,证明了模拟退火算法可以有效的跳出局部最优解的陷阱,快速的找到全局最优解,得到更合理的结果.

| Abstract: | In this paper,the mechanism of supply and demand in microeconomics is applied to analyze the equilibrium. It applies simulated annealing algorithm in analyzing traffic assignment with equilibrium and design a solution to one OD pairs. It makes the user equilibrium model of Beckmann as an example and compiles a Matlab program. The method is effective to jump out the snare of partial optimal. It is more easier than others to finds global optimal and reasonable solution. |
