Leveraging circular economy through a methodology for smart service systems engineering

2019 , Halstenberg, F.A. , Lindow, K. , Stark, R.

Product Service Systems (PSS) and Smart Services are powerful means for deploying Circular Economy (CE) goals in industrial practices, through dematerialization, extension of product lifetime and efficiency increase by digitization. Within this article, approaches from PSS design, Smart Service design and Model-based Systems Engineering (MBSE) are combined to form a Methodology for Smart Service Architecture Definition (MESSIAH). First, analyses of present system modelling procedures and systems modelling notations in terms of their suitability for Smart Service development are presented. The results indicate that current notations and tools do not entirely fit the requirements of Smart Service development, but that they can be adapted in order to do so. The developed methodology includes a modelling language system, the MESSIAH Blueprinting framework, a systematic procedure and MESSIAH CE, which is specifically designed for addressing CE strategies and practices. The methodology was validated on the example of a Smart Sustainable Street Light System for Cycling Security (SHEILA). MESSIAH proved useful to help Smart Service design teams develop service-driven and robust Smart Services. By applying MESSIAH CE, a sustainable Smart Service, which addresses CE goals, has been developed.

Utilization of product lifecycle data from PLM systems in platforms for Industrial Symbiosis

2017 , Halstenberg, F.A. , Lindow, K. , Stark, R.

Industrial Symbiosis represents a promising approach to foster the transformation towards a circular economy. To involve businesses in Industrial Symbiosis, online platforms and input-output matching tools for facilitating the exchange of by-products have been provided by industry organizations and facilitators. Regarding the discrete parts and product manufacturing industry (DPPM), little success is being reported for such platforms and tools. Within the scope of this research, a list of Input-Output matching tools was analysed regarding data sources which are currently used for input-output Matching. Specifications of by-products in the DPPM industry were reviewed in order to identify a list of requirements for data sources. Shortcomings of the currently existing input-output matching tools were identified and suggestions for additional data sources used for input-output matching in IS in DPPM were given. Results show that datasets currently used do not include organisational data sources such as Product Data Management (PDM) systems, Enterprise Resource Planning (ERP) systems, Supply Chain Management (SCM) systems, and or Manufacturing Execution Systems (MES).

Target-oriented modularization - Addressing sustainability design goals in product modularization

2015 , Halstenberg, F.A. , Buchert, T. , Bonvoisin, J. , Lindow, K. , Stark, R.

Through modularization, a large range of sustainability goals can be addressed in design, e.g. environmentally friendly end-of-life or improved MRO (maintenance, repair and overhaul) processes. The development of methods for product modularization raised increasing interest in recent years. However, published methods for product modularization still lack of flexibility and standardization. Numerous methods have been developed that are defined for one or a given list of design goals. As a result, it is still difficult for engineers to find and apply the right method for a defined set of design goals. In this paper, the field of modular product design methods has been analyzed with the aim to develop a Target-oriented Modularization Method that allows defining modular product structure according to user-defined design goals. The introduced method is demonstrated on the example of a Garrett GT2860R turbocharger.
