Optimization of the surface mount technology based on the Max-Min Ant System

The speed of the surface mount equipment is a key factor which influences the efficiency of surface mount process. This paper proposes a new optimization method based on the Max-Min Ant System, which is suitable for surface mount. In the method, the problem of finding the optimal route is converted to that of solving a traveling salesman problem, and a corresponding mathematical model is established. The upper and lower bound of the trail information in the Max-Min Ant System have been analyzed and restricted reasonably. New factors are also added to the equation of path selection probability to improve its performance, and make it more suitable for solving the route optimization problem in surface mount technology. The simulation result of experiments has shown that the method proposed in this paper is more suitable for the route optimization problem in surface mount technology.
