摘要
改进标准蚁群算法的执行策略,可提高工艺规划和调度集成问题的求解质量和效率。通过节点集、有向弧/无向弧集、AND/OR关系,建立了基于AND/OR图的工艺规划和调度集成优化模型。提出一种求解工艺规划与车间调度集成问题的改进蚁群优化算法,采用了信息素动态更新策略避免收敛过慢和局部收敛,利用多目标优化策略提高求解质量。仿真结果证明了该算法的有效性。
The improvement of standard ant colony optimization (ACO) strategy is important to improve the quality and efficiency for integrated process planning and scheduling (IPPS). A graph-based optimization model for IPPS is constructed by means of node set, directed arc set/undirected arc set and relation of AND/OR. An improved ACO for IPPS is proposed, which avoids the slow convergence and the local convergence by dynamic pheromone update strategy, and improves the quality by multi-objective optimization strategy. The simulation result demonstrates the validity of the proposed algorithm for IPPS.
