“…Therefore, this paper mainly focuses on identifying modules that are candidates for part consolidation with considering product recovery. To identify modules, there are many tools for the modular design: axiomatic design, functional modeling, design structure matrix, and modular function deployment [36]. In this step, a functional diagram is used to understand the function flows of a product for identifying modules as shown in Figure 2.…”

“…The DSM provides fundamental information to build an adjacent matrix in Step 3. field of additive manufacturing, it would be helpful to identify parts for consolidation. This is because module identification considers functional relationships, combinability, interface standardization, and interface complexity between parts [36]. Therefore, this paper mainly focuses on identifying modules that are candidates for part consolidation with considering product recovery.…”

Parts with complex geometry have been divided into multiple parts due to manufacturing constraints of conventional manufacturing. However, since additive manufacturing (AM) is able to fabricate 3D objects in a layer-by-layer manner, design for AM has been researched to explore AM design benefits and alleviate manufacturing constraints of AM. To explore more AM design benefits, part consolidation has been researched for consolidating multiple parts into fewer number of parts at the manufacturing stage of product lifecycle. However, these studies have been less considered product recovery and maintenance at end-of-life stage. Consolidated parts for the manufacturing stage would not be beneficial at end-of-life stage and lead to unnecessary waste of materials during maintenance. Therefore, in this research, a design method is proposed to consolidate parts for considering maintenance and product recovery at the end-of-life stage by extending a modular identification method. Single part complexity index (SCCI) is introduced to measure part and interface complexities simultaneously. Parts with high SCCI values are grouped into modules that are candidates for part consolidation. Then the product disassembly complexity (PDC) can be used to measure disassembly complexity of a product before and after part consolidation. A case study is performed to demonstrate the usefulness of the proposed design method. The proposed method contributes to guiding how to consolidate parts for enhancing product recovery.

“…Recently, Borjesson and Hölttä (2014) have proposed an integration of the DSM and MFD approaches in order to balance the two and take into account both interactions and company portfolio strategies. In addition, the VMEA can be used to optimize product modularity by the assessment technical and economic criteria of product variety diversity, integrating business units such as marketing, product program planning, product development, production, and distribution (Stjepandić et al, 2015).…”

“…In this context, adoption of structured functional-based models in industrial practice is still limited due mainly to the difficulties in defining the most proper function-based approach for the specific context of application, and the necessary effort required to properly represent the product knowledge, model the functional solutions, and generate the variants on the basis of the product functions. There are various methods to support modular design for industrial products, from axiomatic design (AD), to design structure matrix (DSM), functional modeling (FM), modular function deployment (MFD), and variant mode and effects analysis (VMEA), which can be also used in combination with an architecture development process (Stjepandić et al, 2015). While AD and DSM are mainly oriented to technical issues and mapping of the relations among product components, FM is a particularly useful method to focus on product functions for structuring the product into modules, to clarify the understanding of a design problem, and to serve as core to the modular solution.…”

Modular product design is an efficient strategy to let manufacturing companies meet the customers' requirements by offering a wide variety and customization of products and significantly saving time and cost during engineering and production (Fei et al., 2011). Despite numerous approaches for function modeling and modular product design (Srinivasan et al., 2012; Eckert, 2013; Vermaas, 2013) that have been developed in the last decades, carrying out an efficient product variants' design process is still an open issue for many manufacturing companies. The proposed approaches offer numerous ways to model information about product functionality, but each approach is useful and particularly well suited for different applications and domains (Summers et al., 2013). The present research compares the existing approaches for product variants design and defines a function-based model to support product design and redesign according to a modular framework, merging qualitative technical issues with business-oriented evaluation. Such a framework has been used to develop a multiuser IT platform, composed of a knowledge-based engine and four different tools to support designers and engineers in product variants creation, management, and configuration, from product functional modeling to cost estimation and life cycle assessment. The proposed model has been tested on industrial cases in the context of household appliances. Experimental results demonstrates that, after a preliminary context analysis and a proper knowledge base creation, such a model supports a more conscious decision-making and promote collaboration within an interdisciplinary design team. Finally, the case study shows the necessity, but in the meanwhile the insufficiency, of a functional decomposition as the only representation viewpoint

Towards a methodology of system manifestation features-based pre-embodiment design

The main assumption is that complicated systems, such as cyberphysical systems (CPSs), can be modelled by specific compositions of system manifestation features (SMFs). SMFs are regarded as architectural domains of a system having significance from an operational viewpoint. As system modelling entities, SMFs represent both physical and computing transformations of domains. Based on mereo-operandi theory (MOT), a computational framework for using SMFs in pre-embodiment design of CPSs is proposed. MOT offers a theoretical platform for concurrent modelling of architectural elements and their operations. The traditional 'application feature technology' has been generalised in order to provide a methodological basis. The computational formalisation captures state transitions and input/ output streams, in addition to spatiotemporal, physical and/or computational attributes of domains. Domain transformations are represented by flows of operation (FoOs) that consist of timesequenced and logically constrained sets of units of operations (UoOs), and processed by various computational methods as procedures. The domains of SMFs are aggregated into a feasible architecture, and their UoOs are combined into FoOs. An application case is used to explain the concepts and to demonstrate feasibility of the proposed approach. Further research will focus on implementation of an SMFs-based preembodiment design system and testing its feasibility and usability with designers of CPSs.
