摘要

在虚拟企业中寻找合作伙伴是一个典型的多目标优化问题,需要进行科学的投标决策。在提出优化模型的基础上,采用改进的遗传算法求解伙伴选择问题。在进化过程中,个体存活率根据轮盘选择前个体适应度值的队列动态变化,避免过早收敛。交叉和变异算子根据适应度值和迭代度进行自适应,使个体具有适应环境变化的自适应性。最后,通过算例验证了自适应遗传算法的有效性。

Multi-objective Optimization in Partner Selection
It is a typical multi-objective optimization problem for the scientific decision of bidding to seek cooperating partner in virtual enterprise. With the optimization model proposed, partner selection is solved by the improved genetic algorithm. In the evolution process, individual survive rate is dynamic according to queue of individuals 'fitness values before roulette wheel selection, avoiding premature convergence. Crossover and mutation operators are accordingly adaptive to fitness value and iterative degree, which endows individuals with self- adaptability with the variation of the environment. Finally, the example demonstrates the validity of the adaptive genetic algorithm.
