Abstract This paper presents an immune ant colony algorithm for multitask scheduling in parallel and distributed systems. Ant colony algorithm is used to evolve a priority list firstly, then the priority list is mapped to a schedule by a greedy strategy. In order to avoid premature stagnation, immune principle is used to preserve the diversity of the population of ants. The simulation results compared with those of genetic algorithm and list scheduling which are typical in literature, show that it produces encouraging results in both solution complexity and execution time.
