Evaluation and Optimization of the Application of Lean Methods

期望的研究项目旨在开发一种方法，通过精益生产方法模拟优化和货币评估增强的制造系统性能。由于在工厂层面上集成生产系统的先进而具体的公司发展，考虑到当前实施程度以及精益生产方法的剩余潜力的方向。分析和优化精益生产方法的定制组合对所分析的制造系统的影响，其目的是利用仿真软件。除了能够预测精益生产方法之间的相互作用外，基于模拟的分析的抽象水平较低，因此是有益的。为了建立基于模拟结果的货币评估，其目的是创建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，例如交货时间、生产成本和包括在内的质量成本。期望的方法不仅应该允许在精益生产方法的帮助下对集成生产系统进行反复的维度划分，并评估在现实中实现理想状态的盈利能力，而且还应该支持鲁棒性分析，例如在模拟模型中不同的产量或不同的产品组合的情况下。因此，在多变的环境中确定潜在的适应时间是可能的。为了推导生产系统适应的行动计划，比较和调整分析的精益生产方法和波动驱动因素的影响是必不可少的。研究问题的基础是以下相关问题：-如何根据目前的实施情况，以目标为导向，针对公司具体开发集成生产系统？-如何评价优化的精益生产方法组合应用的盈利能力？-何时以及如何调整生产系统，例如，由于不同的产量或不同的生产重复？

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?
