A time constrained scheduling method based on dynamic combination of genetic algorithm and ant algorithm

A time constrained scheduling (TCS) method based on dynamic combination of genetic algorithm (GA) and ant algorithm (AA) is proposed in this paper. For RCS problem, chromosome encoding, crossover, mutation and fitness function of GA are defined first, and then the initial pheromone distribution and pheromone updating rule of AA are given. Dynamic switching condition from GA to AA for TCS is also presented finally. Experimental data for TCS indicate that the average resource number needed and average execution time of our method are less than GA and AA respectively.
