针对单项工作时间、质量和项目整体质量约束,如何实现航天器发射工期和质量最优的问题,构筑了质量与时间关系模型,建立了基于粒子群和遗传策略对航天器发射工艺流程进行工期和质量优化的算法。实例验证表明该方法可用于航天器发射工艺流程中工期与质量的推演和时间调度方案的优化。 Aiming at the problems of individual work time, quality and overall project quality constraints, how to achieve the optimal launch schedule and quality of the spacecraft, a model of the relationship between quality and time was constructed. The model based on particle swarm optimization and genetic strategy Quality Optimization Algorithm. The example verification shows that this method can be used to deduce the construction schedule and quality of spacecraft launch process and the optimization of time scheduling scheme.
