基于改进捕食搜索算法的IT外包进度风险控制

摘要

提出了IT服务外包项目的两层进度风险控制模型.针对间题中两层结构的特点和捕食搜索算法(PS)在寻优中的效率间题,分别引入了两层结构和基于2-opt寻优方式的禁忌机制,设计了两层禁忌捕食搜索算法(TLTPS).在仿真实验中,首先给出了仿真结果,进而,在5个不同规模的算例下,比较了TLTPS与GA、PSO和PS的仿真实验结果,验证了该算法的合理性和有效性.%A two-level IT outsourcing schedule risk control model is proposed. For the two-level structure of the problem and the efficiency of Predatory Search (PS), the two-level structure and 2-opt based Tabu mechanism are introduced to propose a two-level tabu-predatory search (TLTPS) algorithm. During simulation examples, firstly, the simulation results are given. Secondly, five simulation experiments of different sizes are introduced to compare the ability of TLTPS, GA, PSO and PS, and verify the rationality and effectiveness of the improved algorithm.
