Evaluation and Optimization of the Application of Lean Methods

该研究项目旨在开发一种方法，通过精益生产方式对增强的制造系统性能进行模拟优化和货币评估。由于在工厂一级对综合生产系统进行了先进而又特定于公司的开发，因此可以考虑以当前的实施程度和精益生产方式的剩余潜力为导向。分析和优化定制的精益生产方式组合对被分析制造系统的影响，目的是利用仿真软件。除了预测精益生产方式的交互作用之外，基于模拟的分析的抽象程度较低，因此是有益的。为了根据模拟结果建立货币评价，其目的是建立一个能够主动支持管理决策的框架。它应该与上级关键绩效指标保持一致，如交付期、生产成本和包含的质量成本。所追求的方法不仅应允许在精益生产法的帮助下反复确定综合生产系统的规模，并评估在现实中实施理想状态的盈利能力，而且还应支持在模拟模型内进行稳健性分析，例如在生产量不同或产品组合不同的情况下。因此，可以识别在易变环境中的潜在适应时间。为了推导出适应制造系统的行动计划，必须比较和调整分析的精益生产方式的效果和波动的驱动因素。研究问题背后有以下相关问题：-如何根据当前的实施状况开发面向目标和特定于公司的集成生产系统？-如何评估应用优化的精益生产方式组合的盈利能力？-何时以及如何适应制造系统，例如，由于产量变化或重复不同的生产？

The aspired research project aims at developing a methodology to simulatively optimize and monetarily evaluate an enhanced manufacturing system performance by means of lean production methods. Due to an advanced yet company-specific development of integrated production systems on a factory level an orientation towards current implementation degrees as well as towards remaining potentials of lean production methods is contemplated. Analyzing and optimizing the impacts of a tailored combination of lean production methods on the analyzed manufacturing system it is aimed at utilizing simulation software. Besides the ability to forecast the interaction of lean production methods the abstraction level of a simulation-based analysis is low and therefor beneficial. In order to establish a monetary evaluation based on simulation results it is aimed at creating a framework capable to support management decisions proactively. It should be aligned to superordinate key performance indicators, such as lead times, production costs, and included quality costs. The aspired methodology should not only allow for a recurring dimensioning of the integrated production system with the help of lean production methods and an evaluation of the profitability of the implementation of an ideal state in reality, but also support a robustness analysis, e.g. in case of varying production volumes or a differing product mix, within the simulation model. Thereby it is possible to identify potential adaption times within a volatile environment. To deduct action plans for the adaption of the manufacturing system it is essential to compare and adjust effects of analyzed lean production methods and drivers of volatility.Underlying the research problem are the following relevant questions:- How to develop an integrated production system goal oriented and company specific based on the current implementation status?- How to evaluate the profitability of an application of an optimized lean production method combination?- When and how to adapt a manufacturing system e.g. due to varying production volumes or a differing production repeatedly?
