Abstract: With the rapid development of IT outsourcing projects in recent years, the schedule risk control has also become one of the urgent issues to be solved. Based on the optimization problems of schedule risk control in IT outsourcing projects, a two-level mathematical model was built. For the NP hard and hierarchical structure of the optimization problem, the basic tabu search algorithm was improved in generating initial solution with heuristic methods and constructing dynamic tabu list. According to the result of simulation experiment, the improved algorithm was analyzed in reliability, convergence and effectiveness. In addition, the simulation results were also compared with traditional tabu search algorithm, and the value of the improved tabu search is verified.

Key words: tabu search, IT outsourcing project, schedule risk, risk management
