Neural Network Hyperparameter Optimization for the Assisted Selection of Assembly Equipment

Hagemann, Simon ; Sünnetcioglu, Atakan ; Fahse, Tobias ; Stark, Rainer (2019-12-16)

The design of assembly systems has been mainly a manual task including activities such as gathering and analyzing product data, deriving the production process and assigning suitable manufacturing resources. Especially in the early phases of assembly system design in automotive industry, the complexity reaches a substantial level, caused by the increasing number of product variants and the decr...

Systematic Literature Review of System Models for Technical System Development

Schmidt, Marvin M. ; Zimmermann, Thomas C. ; Stark, Rainer (2021-03-28)

In Model-Based Systems Engineering (MBSE) there is yet no converged terminology. The term ‘system model’ is used in different contexts in literature. In this study we elaborated the definitions and usages of the term ‘system model’, to find a common definition. We analyzed 104 publications in depth for their usage and definition as well as their meta-data e.g., the publication year and publicat...

OPEN_NEXT – Deliverable 5.2: First release of prototyping improvement logic (PIL)

Peters, Ina ; Hofer, Margit ; Voigt, Christian ; Gloß, Thomas Maximilian (2020-12)

As places of intersection between society and technology with great experience in community management and co-development practices, makerspaces can have a huge impact on open source (product) development projects (OSD) in the context of company-community collaboration (C3). As a source of an open source mind-set and as prototyping facilities, they can decrease the distance between the design p...

Systematic Literature Review—Effects of PSS on Sustainability Based on Use Case Assessments

Blüher, Till ; Riedelsheimer, Theresa ; Gogineni, Sonika ; Klemichen, Antje ; Stark, Rainer (2020-08-27)

Product-service systems (PSS) are often presented as an inherently sustainable business model. The argumentation is often based on theoretical considerations, which cite circular economy (CE) characteristics in PSS business models as an explanation. In this paper we examined to what extent positive and negative sustainability effects of PSS could actually be observed, based on use cases. For th...

An optimal algorithm for the robotic assembly system design problem: An industrial case study

Hagemann, Simon ; Stark, Rainer (2020-09-03)

The design process of flow-oriented assembly systems is characterized by being both highly complex and time consuming. Especially those design processes categorized into robotic and multi variant encountered in the automotive body-in-white production stages. Unlike established manual and template-based assembly system design models, which are currently applied in industry, the here presented no...

Hybrid Artificial Intelligence System for the Design of Highly-Automated Production Systems

Hagemann, Simon ; Sünnetcioglu, Atakan ; Stark, Rainer (2019-01-25)

The automated design of production systems is a young field of research which has not been widely explored by industry nor research in recent decades. Currently, the effort spent in production system design is increasing significantly in automotive industry due to the number of product variants and product complexity. Intelligent methods can support engineers in repetitive tasks and give them m...

SW-Code_II for semantic data linking

Fresemann, Carina (2020-07-20)

This software code supports engineeres linking produkt data to order giving struktures. The here given example uses product data, such as CAD oder Simulation Files and relates it to functional structures, modular kits, etc. The applied software is rule-based and support the analysis of the data content as well.

SW-Code_I for semantic data linking

Fresemann, Carina (2020-07-20)

This software supports engineers when allocating product data to structures or concepts. The here engaged used case refers to product data sheets, describing a product or a part of it, as well as export controll regulations, that have to be met. The software uses semantic technologies mainly from the area of NLP combined with rule based methods.

SW-Code for plausible GeometricData

Fresemann, Carina (2020-07-03)

Software Code, describing a routine for analysing geometric data in STEP File Format. The Code is intended to support engineers in the frame of variant management in PDM systems. These currently lack mechanisms for automatically check data for their compatibility to each other. This algorithm provides a solution for geometric data within one variant.

Statistical check of meta data

Fresemann, Carina (2020-07-13)

The SW Code searches within a variant, if meta data match each other. The Code has been written with the intention to support engineers by automatically verifying meta data. The Code learns via a KNN algorithms about historical variant descriptions. It reveals not plausible data without human interaction.

Chat Bot for variant management

Fresemann, Carina (2020-06-15)

The SW code describes a Chat Bot, that allows a user to store product data in relation to variants in a PDM System or other data base. It is intended to support engineers by delivering variant information from a CAD environment towards PDM System using natural language. Applying NLP releases the engineer from knowing variant codes and changing the system.

Natural Virtual Reality User Interface to Define Assembly Sequences for Digital Human Models

Geiger, Andreas ; Brandenburg, Elisabeth ; Stark, Rainer (2020-03-12)

Digital human models (DHMs) are virtual representations of human beings. They are used to conduct, among other things, ergonomic assessments in factory layout planning. DHM software tools are challenging in their use and thus require a high amount of training for engineers. In this paper, we present a virtual reality (VR) application that enables engineers to work with DHMs easily. Since VR sys...

Method for automated structuring of product data and its applications

Adolphy, Sebastian ; Grosser, Hendrik ; Kirsch, Lucas ; Stark, Rainer (2015)

Product structures represent the data backbone for through-life management of complex systems. Product Lifecycle Management (PLM) Systems are used to maintain product structures and track product changes. However, in maintenance, repair and overhaul (MRO) product composition often is unknown when MRO service providers are not the original manufacturers. Thus, MRO processes start with an exhaust...
