Within emerging markets, ensuring the competitiveness of manufacturing companies is crucial to their success. The integration of new business possibilities, such as Product-Service-Systems (PSS) can provide one suitable solution. Especially within the architecture development process, large amounts of interconnected data and data types need to be processed and versioned. This leads to a significant lack of data consistency and continuity along the development process of modular PSS architectures. This lack of consistency and continuity leads to a process being prone to errors, representing a significant negative impact onto the company’s value-added stream. We provide one possible solution to these issues by presenting a PSS architecture modularization approach based upon the modularization methods of the Integrated PKT-Approach. Using concepts of Model-Based Systems Engineering (MBSE) for modelling these architectures, automated and dynamic analyses of the architecture for the iteration and harmonization of the PSS architecture under development are enabled. The at first generically described approach is further detailed in the second part of this contribution by applying it to an industry case study for mobile laser welding systems. As a result, a clear support for the visualization of architecture iteration aspects as well as for the enhancement of data consistency and continuity is given.

In methodical product development, numerous data are used and linked with each other, especially variant-related data. This paper presents a model-based solution for avoiding inconsistencies in the development of product families with many variants and extends it to modular lightweight design. In addition, the inconsistencies in methodical product development were classified and solution approaches were shown. Thus, inconsistencies can be avoided with the presented elaborated data model for an integrated product and process model based on the presented procedure.

This paper shows how a methodical development and configuration of modular product family concepts and their effects on economic targets can be implemented in SysML. For this purpose, different sources of inconsistency between different methodical tools are highlighted and the need for research is shown. As a solution approach, a methodical framework is presented, which can be used to implement product development methods for the developing of modular product family modeling by means of Model-Based Systems Engineering (MBSE) in the modeling language SysML. By applying the framework, it is shown on the one hand how a product family of vacuum cleaner robots as a simple example can be modularized in a methodical, model-based manner. On the other hand, a configuration system and an impact model of modular product families are connected with the system model and applied to a product family of laser systems as an industrial use case. This made it clear that the framework can be used to model various methodical topics of product family modeling in a consistent manner, to enable higher-level analyses with the use of MBSE tools. This can reduce errors, decrease effort and increase traceability across different methodical tools.

Aircraft cabin monuments must be optimized in terms of lightweight design, cost structure and variance. Model-based approaches support the aircraft data and help to modify them consistently during further development. In this paper, a holistic methodological approach for product families of aircraft cabin development is shown, which integrates lightweight and cost-efficient aspects, in addition to the variance focus. For this purpose, the development of cost-efficient and ligthweight optimized cabin modules is supported in a model-based way.
