Development of a comprehensive model of labor productivity and the logistic objectives

科学界和实践者都认为，生产计划和控制(PPC)和生产力管理基本上是分开的领域。这是合理的，因为任务和方法不同。然而，它带来了忽视这些学科之间基本关系的风险：购买力平价在很大程度上决定了生产的投入和产出，这是生产率的两个主要因素，因此如果不调整购买力平价参数，生产率的提高将是无效的。到目前为止，还没有一个模型，以一致的术语全面描述PPC和生产率管理之间的关系，并建立在定量相关性的基础上。本研究项目的目的就是开发这样一个模型。为了实现这一目标，第一个主要目标是开发一个一致的生产力管理模式。该模型旨在描述生产率管理中尚未定义的功能如何调节执行变量，从而通过控制变量决定劳动生产率。第二个主要目标是将该模型与现有的制造控制模型相连接。由此得到的总体模型应(1)定性和定量地描述PPC与生产率管理之间的相互依赖关系，(2)推导出主要关系和目标冲突，(3)使PPC与生产率管理能够系统地、协调地配置。

Both the scientific community and practitioners perceive Production planning and control (PPC) and productivity management as mostly separated fields. This is reasonable because the tasks and methods differ. However, it evokes the risk to overlook fundamental relations between these disciplines: PPC greatly determines the input and the output of a production, the two main factors of productivity, so that productivity improvements will be ineffective without adjusting the PPC parameters.So far, a model is missing, that thoroughly describes the relationships between the PPC and productivity management with a consistent terminology and that is based on quantitative correlations. The aim of this research project is to develop such a model. To achieve this, the first main objective is to develop a consistent model for productivity management. The model is intended to describe, how the yet to be defined functions of productivity management regulate the actuating variables, which in turn determine labor productivity via the control variables.The second main goal is to connect this model with the existing manufacturing control model.The resulting overall model should (1) describe the interdependencies between PPC and productivity management qualitatively and quantitatively, (2) deduce the main relationships and target conflicts and (3) enable a systematic and coordinated configuration of PPC and productivity management.
