WiMo-Trans - Validation and further development of an impact model for describing the effects of modular product structure in manufacturing industry

制造企业面临着挑战，原因是市场更加全球化，竞争更加激烈，以满足个性化的大趋势。他们通过各种提供的产品变种实现了这一点，为客户提供了更多的产品种类。其结果是，公司的复杂性日益增加，如成本上升、交货时间延长和错误率上升。利用模块化，模块化产品结构的开发避免了这种变化引起的复杂性，从而可以提供高客户(外部)产品多样性和同时较低的内部多样性。在DFG项目WIFO中，开发了一个基本的理论模型，用于描述属性和具体确定模块化产品结构在所谓的效果链中的影响，其中来自文献的现有部件模型已经被集成和合并。在对模块化产品结构的影响进行具体调查时，特别考虑了以前存在的知识差距。从我们自己的研究项目以及文献中对现有的案例研究进行了补充分析，并将其整合到影响模型中。由此产生的影响模型将在与西门子，特别是与西门子咨询公司的转移项目中得到验证，同时也将进一步细化和扩展。西门子咨询公司在模块化项目方面拥有10多年的行业经验，因此是这个转让项目的理想合作伙伴。应对来自西门子不同业务领域的三个模块化项目进行验证。特别是，量化效应链的目标来自行业合作伙伴的极大兴趣，因为对成本、时间和质量目标的预测应该是可能的。此外，还应能够通过扩展影响模型的时间维度来说明某些影响的发生。尽管如此，示范效应链的详细说明应该可以定量衡量影响，这只能与工业合作伙伴一起测试和评估。为了更好地管理扩展的和更详细的影响模型，它应该用MBSE工具表示，以更好的方式分析量化。

Manufacturing companies face the challenge due to more global and competitive markets to meet the individualisation mega-trend. They realise this by various offered product variants to provide the customer a high product variety. As a result an increasing complexity in the companies, such as rising costs, increased delivery times and higher error rates are implicated. Using modularisation the development of modular product structures avoids this variant induced complexity, so that high customer (external) product variety with simultaneous lower internal variety can be offered.In the DFG project WiMo " Development of a model describing the characteristics and effects of modular product structures to assess methodological approaches” a basic theoretical model was developed for the description of properties and specific determination of the impact of modular product structures in so-called effect chains in which existing part models from the literature have been integrated and merged. The previously existing knowledge gap was especially considered in relation to the specific investigation of the impact of modular product structures. Complementing existing case studies from our own research projects as well as the literature were analysed and integrated into the impact model.The resulting impact model will be validated in the transfer project with Siemens, in particular with Siemens Consulting, but also at the same time further detailed and extended. Siemens Consulting brings its own industrial experience of modularisation projects for over 10 years and is therefore an ideal partner for this transfer project. The validation shall be made on three modularisation projects carried out from different business areas from Siemens. In particular the objective of quantifying the effect chain is from great interest for the industry partner, because a forecast of the targets of cost, time and quality should be possible. In addition, it should be possible to make statements to the occurrence of certain effects through the extension of a temporal dimension at the impact model. Still it should be possible that a detailing of exemplary effect chains can quantitatively measure the impact, which only can be tested and evaluated with an industrial partner. For a better management of the extended and more detailed impact model it should be represented in a MBSE tool, to analyse the quantification in a better way.
