Today’s production systems need to adapt rapidly to changing product requirements. Adaptation can be eased by formal models, representing product requirements and system capabilities, which convey the needed information for adaptation planning activities. This paper presents an adaptation approach, which is based on matching the product requirements to the resource capabilities, and applies it to a practical case study in TUT-microfactory environment.
The aim of the present paper is to introduce a feature-based Product-Process-System model and ontology in order to retrieve and share knowledge for simulation of manufacturing systems. Product knowledge is the combination of product specific information, such as functionality, colour and product variants, and the corresponding product model. The model provides understanding of the product structure, rules, constraints and assembly-specific information in relation to the product model. In the design and modeling of assembly processes, features form the foundation for analysis and knowledge acquisition of the product. This knowledge includes geometric and non-geometric information. In the present paper, an approach is proposed to share platform independent product-process knowledge between the assembly process and system design and even with the simulation environment.
The research in mini, micro and desktop factories originates from early 90's and has continued since then by developing the technological basis and different technological building bricks and applications in the field of high-precision manufacture and assembly of future miniaturized and micro products. This has paved the way to mini, micro and desktop factories which are seen as one potential solution for that kind of production by improving space, energy and material resource utilization and answering to the needs of design for postponement and customer-close customization and personalization. The research efforts done during these years are now increasingly leading also to commercialization and real industrial applications. The objective of this paper is to present an overview of the international microfactory research and to introduce in more detail the modular microfactory concept developed in the M4-project.
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
