ISO 18828-4:2018规定了生产计划中的一组关键绩效指标，允许在标准化框架内对生产计划过程进行比较和监控。 作为第一步，详细阐述了关键绩效指标的使用，以便在考虑规划过程不同范围的情况下，将指标组织在一个多层次系统中。多层次系统的开发代表了ISO 18828-4:2018的核心。ISO 18828-4:2018中讨论的计划过程的范围仅限于批量生产产品的生产计划。这种方法只考虑在生产计划过程中执行的任务。 所提供的所有关键指标均为建议，也可根据ISO 18828-2中参考过程的一般有效性使用，并与ISO 18828-4:2018中描述的内容相关。

ISO 18828-4:2018 specifies a set of key performance indicators in production planning, which allow comparison and monitoring of the production planning process in a standardized framework. As a first step, the utilization of the KPIs is elaborated in order to organize the indicators in a multi-level system taking different ranges of the planning process into account. This development of a multi-level system represents the core of ISO 18828-4:2018. The scope of the planning processes discussed in ISO 18828-4:2018 is limited to production planning for products in series production. Only tasks carried out within the production planning process are considered in this approach. All key indicators presented are recommendations and can also be used in accordance with the general validity of the reference process from ISO 18828？2 and relate to the content described in ISO 18828-4:2018.
