Electronic appliance manufacturers are facing the challenge of frequent product orders. Based on each product order, the assembly process and workstations need to be planned. An essential part of the assembly planning is defining the assembly sequence, considering the mechanical product’s design, and handling of the product’s components. The assembly sequence determines the order of processes for each workstation, the overall layout, and thereby time and cost. Currently, the assembly sequence is decided by industrial engineers through a manual approach that is time-consuming, complex, and requires technical expertise. To reduce the industrial engineers’ manual effort, a Computer-Aided Assembly Sequence Planning (CAASP) system is proposed in this paper. It compromises the components for a comprehensive system that aims to be applied practically. The system uses Computer-Aided Design (CAD) files to derive Liaison and Interference Matrices that represent a mathematical relationship between parts. Subsequently, an adapted Ant Colony Optimization Algorithm generates an optimized assembly sequence based on these relationships. Through a web browser-based application, the user can upload files and interact with the system. The system is conceptualized and validated using the CAD file of an electric motor example product. The results are discussed, and future work is outlined.
Networked digitalisation as an enabler for smart products and data-based business models presents companies with numerous and diverse challenges on their way through the digital transformation. Various reference architecture models have been developed in recent years to support these companies. A detailed analysis of these and in particular their use by companies quickly showed that currently existing reference models have major weaknesses in their practical suitability. With the Aachen Digital Architecture Management (ADAM), a framework was developed that specifically addresses the weaknesses of existing reference architectures and specifically takes up their strengths. As a holistic model, specially developed for use by companies, ADAM structures the digital transformation of companies in the areas of digital infrastructure and business development starting from customer requirements. Systematically, companies are enabled to drive the design of the digital architecture, taking into account design fields. The description of the design fields offers a detailed insight into the essential tasks on the way to a digitally networked company. The model is not only a structuring aid, but also contains a construction kit with the design fields to configure the procedure in the digital transformation. The procedure differentiates between the development of the digitalisation strategy and the implementation of the digital architecture. Three different case studies also show how ADAM is used in industry, what structuring support it can provide and how the digital transformation can be configured. The breadth and depth of ADAM enable companies to take the path of digital transformation systematically and in a structured manner, without ignoring the value-creating components of digitalisation. This qualifies ADAM as a sustainability-oriented framework, as it places the economic scaling, needs-based adaptation and future-oriented robustness of solution modules in the focus of digital transformation.
