Abstract
The efficiency E of a punch for making printed wiring boards is decided by its cost and time. The weight of cost and time is different in different companies. In this paper, we establish a bi-object programming model to measure E. We use an algorithm for obtaining an order of tool switching. Considering how to calculate the shortest path for every tool, we compare three modern optimizationalgorithms. We find Ant colony Algorithm is best in computing the shortest path, but it will cost a lot of time in running. Genetic Algorithm is better than Simulated Annealing Algorithm in time and cost. We make some improvements on these algorithms.
