Design Automation has been in focus of research and application for several decades. This paper aims at establishing the current view of design automation and identification of potential for adoption based on a survey conducted in German speaking countries and a hypothesis based multivariate analysis based on networks. The findings show that design automation is still considered a means of automation of repetitive design tasks and potential for enhanced application exists. The necessity for methods supporting designers for identification and definition of design automation tasks is urged.
The re-use of product knowledge is vital to the development of Knowledge-Based Engineering (KBE) systems and to the deployment of Product Lifecycle Management (PLM) strategies. This paper addresses the challenges related to KBE-PLM systems integration in order to unlock engineering knowledge from proprietary representations and to manage the lifecycle of KBE models as well as their usage by different design automation applications. Essential constituents of product knowledge are identified and analyzed and the concepts of design intent and design rationale are reintroduced as key enablers to re-use this product knowledge in the appropriate KBE context. The paper introduces a KBE-PLM integration framework including a platform-independent Open KBE repository structured according to the KBE-PLM integration schema. This schema is a multi-layer neutral product and knowledge data model designed for integrating information from parameterized Computer-Aided Design (CAD) models, rule-based KBE systems and PLM systems.
Purpose
The paper aims to raise awareness in the industry of design automation tools, especially in early design phases, by demonstrating along a case study the seamless integration of a prototypically implemented optimization, supporting design space exploration in the early design phase and an in operational use product configurator, supporting the drafting and detailing of the solution predominantly in the later design phase.
Design/methodology/approach
Based on the comparison of modeled as-is and to-be processes of ascent assembly designs with and without design automation tools, an automation roadmap is developed. Using qualitative and quantitative assessments, the potentials and benefits, as well as acceptance and usage aspects, are evaluated.
Findings
Engineers tend to consider design automation for routine tasks. Yet, prototypical implementations support the communication and identification of the potential for the early stages of the design process to explore solution spaces. In this context, choosing from and interactively working with automatically generated alternative solutions emerged as a particular focus. Translators, enabling automatic downstream propagation of changes and thus ensuring consistency as to change management were also evaluated to be of major value.
Research limitations/implications
A systematic validation of design automation in design practice is presented. For generalization, more case studies are needed. Further, the derivation of appropriate metrics needs to be investigated to normalize validation of design automation in future research.
Practical implications
Integration of design automation in early design phases has great potential for reducing costs in the market launch. Prototypical implementations are an important ingredient for potential evaluation of actual usage and acceptance before implementing a live system.
Originality/value
There is a lack of systematic validation of design automation tools supporting early design phases. In this context, this work contributes a systematically validated industrial case study. Early design-phases-support technology transfer is important because of high leverage potential.
Abstract. This paper aims at illustrating some limitations of the systemic approach when willing to ensure the interoperability of PLM solutions within a Dynamic Manufacturing Network (DMN), based on e-Business PLM standards and their implementations, being industrial processes, methods, applications or Information & Communication Technologies (ICT) solutions. Indeed, addressing interoperability challenges in such a complex digital business eco-system calls for a holistic approach based on the "system" paradigm. Setting this way, a part of our goal is to underline the limits and drawbacks of such an approach as interoperability brakes and to derive the issues that must be addressed in terms of research in order to remove them. This paper introduces a new approach in order to set up a test bed environment for PLM standards. The required and proposed approach considers a PLM standard not only as a technical solution, but above all as a strategic solution for which it is mandatory to support and enhance discussions between enterprise, product/system, processes, ICT architects and designers. The proposed approach -for analyzing and assessing the relevancy of PLM standards regarding their usage in specific business contexts -will be illustrated with a multi-layer modeling language. This language is used to model standards-based business collaboration scenarios and to model the test bed environment that will enable the execution/simulation of this scenario and the assessment of related standards implementations regarding the business needs of the scenario. The addressed case study is based on a data exchange scenario between a customer production order scheduler and a supplier production order executer using the ISA 95 standard. From this example, the interoperability issues related to DMN system of systems will be identified, for which accurate test based methods will be defined in future work.
