先进规划调度系统（APS，Advanced Planning & Scheduling System）是一种以系统仿真或数理规划等方式填写甘特图。

一般业界的ERP能集成企业的数据，但欠缺调度的功能，APS则拥有「决策支持」的能力，可以随异常状况如缺料、停机、插单、数量调整、工期调整、加班设置等而调整。APS可以让规划者快速结合生产相关信息，例如订单（Order）、制令（MO，或称工单）、途程（Route）、半成品（WIP）、存货（Stock）、物料清单（BOM）等。随着企业之间的差异性，生产相关信息亦不尽相同，如制令之下可能还有批量（Lot）。

Advanced planning and scheduling (APS, also known as advanced manufacturing) refers to a manufacturing management process by which raw materials and production capacity are optimally allocated to meet demand. APS is especially well-suited to environments where simpler planning methods cannot adequately address complex trade-offs between competing priorities. Production scheduling is intrinsically very difficult due to the (approximately) factorial dependence of the size of the solution space on the number of items/products to be manufactured.
