摘要

摘要: 针对复杂产品生产业务调度这一问题，该文运用工作流技术并以完工时间为约束，提出一种虚拟迭代归约算法，能较好地在完工时间约束下优化生产精确率。通过将各制约任务抽象虚拟成一个虚拟节点，采用逆向迭代的求解方式，确定了一条兼顾完工时间与生产精确率的调度路径。对比发现，虚拟迭代归约算法对全局生产精确率有较大幅度的提高，且通过改变截止期、任务数等参数可以提高算法的效率。

Abstract: For the problem of the production of complex operations, this paper uses workflow technology and takes the completion time as constraint, and proposes a Virtual Iterative Reduction Algorithm (VIRA) to achieve better production accuracy in the constraint completion time. By virtualizing tasks in mutual constraint into a virtual node, the algorithm uses inverse iterative way to determine a path that completion time and production accuracy get balance. By comparison, the virtual iterative reduction algorithm can increase the production accuracy in the constraint completion time, and it is found to improve the accuracy of the algorithm by changing the deadline, the number of tasks and other parameters.
