To address the continued lack of evidence-based system solutions, this study presents a holistic design framework and a novel computational platform for enabling design explorations of integrated pharmaceutical product and supply chain (SC) reconfiguration. The design and modelling framework developed herein takes an end-to-end SC perspective, adapts the mass customisation strategies of product modularisation and postponement, and demonstrates case study simulations based on real-life therapy and SC archetypes. The cost-effectiveness assessment with the derived integrated systems computational platform confirm that product modularisation drives patient benefit through variety provision and that postponement drives cost reduction in an end-to-end SC. A novel insight is therefore that both product modularisation and postponement, in an integrated manner, are required for maximising cost-effective customisation. Moreover, the computational simulations, founded and modelled on real-life scenarios, provide design requirements for reconfigurable product and SC systems in a pharmaceutical context. In all, these findings are imperative for providing guidance on integrated pharmaceutical product and production systems design and mass customisation/ mass personalisation/mass individualisation realisation.","PeriodicalId":50207,"journal":{"name":"Journal of Engineering Design","volume":"54 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135315893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the assembly process information for wind turbines is typically dispersed among various modalities such as 3D models, natural text, and images in the form of process documents. The difficulty in effectively utilising historical process knowledge hampers the efficiency of assembly process design and subsequently affects production efficiency. To address this issue, this paper constructs a Multi-modal Process Knowledge Graph for Wind Turbines, named MPKG-WT. Additionally, a wind turbine assembly process question-answering system combining multi-modal knowledge graphs with large language models (LLMs) is proposed to enable efficient utilisation of historical assembly process knowledge. The proposed approach achieves outstanding results when compared with other state-of-the-art KBQA methods and recent LLMs using a wind turbine assembly process dataset. The effectiveness of the approach is further validated through a visualised assembly process question-answering system. The research findings demonstrate a significant improvement in assembly process design efficiency.KEYWORDS: Multi-modal knowledge graphWind turbinesAssembly process knowledgeLarge language modelQuestion answering Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by National Key Research and Development Program of China: [grant no 2019YFB1706300]; Shanghai Rising-Star Plan (Yangfan Program) from the Science and Technology Commission of Shanghai Municipality: [grant no 22YF1400200].","PeriodicalId":50207,"journal":{"name":"Journal of Engineering Design","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135316284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, conventional approaches often fixate solely on design aspects, overlooking downstream supply chain configuration (SCC) considerations and the corresponding environmental benefits. Consequently, there is an escalating demand for an integrated optimisation approach that encompasses both PFC and SCC to realise economic and environmental advantages. This study delves into a methodology that integrates blockchain smart contracts as binary 0–1 variables with waste recycling and utilisation, yielding a comprehensive multi-objective model. The proposed methodology seamlessly incorporates considerations for both PFC and SCC. Furthermore, a nested leader-follower optimisation algorithm, based on the non-dominated sorting genetic algorithm-II (NSGA-II), has been devised with the objective of achieving triple benefits: augmented profits, maintenance revenue, and diminished environmental emissions. In conclusion, this research contributes to the advancement of sustainable collaborative optimisation through the innovative utilisation of blockchain smart contracts and multi-level modelling. To demonstrate the effectiveness of the proposed methodology, it is applied to a 60 KW DC electric vehicle (EV) charging piles, accompanied by a sensitivity analysis to assess its management implications.KEYWORDS: Product family configurationsupply chain configurationleader-follower optimisationnon-dominated sorting genetic algorithm-IIDC charging piles AcknowledgmentsThe authors would like to thank Keda Intelligent Technology Co., Ltd.

In response, the study provides a framework for generalising design requirements documents into topics that engineers can use to understand complex designs. Based on previous work, this study employs and compares four different models, including latent Dirichlet allocation (LDA), the collapsed Gibbs sampling algorithm for the Dirichlet multinomial mixtures model (GSDMM), LDA-BERT, and GSDMM-BERT to determine the appropriate representation of requirements documents. Both heatmaps and UMAPs are used to illustrate the correlation between topics and words. The results indicate that the combined vector representation of topic modelling and the sentence-BERT model outperforms single topic modelling. This combined model leverages the additional knowledge from a pre-trained sentence-BERT model, thereby improving model performance and word distribution in all three industrial projects.

Examples of self-engineering responses include self-healing, self-repair, self-adapting and self-reconfiguration. Biology already utilises many of these responses to repair and survive, greater understanding of complexity in these biological systems could improve future bioinspired designs. This paper provides a novel systematic evaluation of the complexity of SE biological systems. Eight biological self-engineering systems identified are evaluated using Axiomatic design and complexity. The key functional requirements and design parameters for each biological system are identified. Design matrices were used to highlight different types of complexity. A further evaluation of eight SE biological systems is performed using the SE complexity theory; nine experts and 23 students used the complexity theory to complete a ranking exercise. The results of the ranking were analysed and compared, with a final normalised mean plotted for each factor and biological system. From the analysis of both studies, proposed design rules are presented to help designers handle complexity while creating new self-engineering systems inspired by biology.KEYWORDS: Self-healingself-repairself-engineeringbioinspireddesign AcknowledgementsThe authors would first like to thank all the student and expert participants who agreed to take part in the exercise detailed in Section 5.

However, the uncertainty inherent in these assumptions constitutes a risk that ought to be mitigated. That is, assumptions can negatively impact the system if they turn out to be invalid. Adverse effects may include system failure, violation of requirements, or budget and schedule overruns. In this paper, the relationships between assumptions and margins are made explicit, with the purpose of aiding risk mitigation, as well as accommodating future opportunities such as product evolvability. To this end, a novel assumption management framework is proposed, which consists of a taxonomy of margins, an algorithm for change absorber localisation, and an interactive approach for margin trade-off. The proposed framework is demonstrated with a conceptual aircraft design use case, which shows that the most relevant margins can be identified, given a revision of a set of assumptions. It is also demonstrated that the application of the method allowed the margins to be adjusted according to the confidence in the assumptions, while maintaining satisfaction of all design constraints, without unacceptable compromise of system performance.","PeriodicalId":50207,"journal":{"name":"Journal of Engineering Design","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136097964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decisions in the design stage often have the most impact in affecting attributes of a product such as the product’s environmental sustainability. Although the impacts and benefits are obvious, the development of environmentally sustainable products is often avoided due to a lack of trained designers. Different tools have thus been developed to address this deficiency. In this paper, we review ecodesign tools developed to aid designers in product design. Through a systematic literature review, 141 articles were assessed and grouped into design generation, assessment, and selection. The goal of the review is to identify existing ecodesign tools in the literature, find out how these tools help designers to lower the environmental impact of their designs, and the limitations of existing tools. Finally, we propose an ecodesign system comprising 10 modules.","PeriodicalId":50207,"journal":{"name":"Journal of Engineering Design","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135789677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Competitive specifications’ determination requires a better understanding of the comparison-oriented product competition mechanism. Big sales data that consist of comprehensive and multi-dimensional datasets of products are valuable sources for the investigation of the specification competition mechanism. In this work, the relative satisfaction hypothesis and rational comparison hypothesis are proposed on the basis of product competition analysis. A framework is proposed to support rational design decisions in the context of competitiveness-oriented design optimisation. This framework is based on game analysis of product specifications using big sales data. Initially, competing products in the market are collected and modelled for game analysis. To monitor the competition mechanism of specifications amongst competing products, the relative satisfaction is then defined to evaluate the comparison results of product specifications. By comparing different specifications and their combinations, four design scenarios (i.e. dominant, dominated, equivalent and mixed design) are identified for design evaluation. Similarities amongst specifications are considered for supporting both homogeneous and differentiated competition. Ultimately, a bi-level optimisation model is proposed for enhancing product competitiveness. A case study illustrates the implementation of the proposed method.KEYWORDS: Product designcompetition analysisgame theorydesign optimisationbig sales data AcknowledgementsThe authors thank the National Key Research and Development Program of China (No: 2018YFB1701701), and Special Grand from Tianjin City Government, China for providing financial support to this research.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the National Key Research and Development Program of China [grant number 2018YFB1701701].","PeriodicalId":50207,"journal":{"name":"Journal of Engineering Design","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136280334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper addresses the twofold challenge of establishing a suitable concept of margins early in the design process, before the design is mature enough for detailed modelling, and evaluating margin inter-dependencies. As margins are often specified in an unstructured manner, there is a risk that one margin might lead to a need for more margins, e.g. tight tolerances, downstream.To avoid adverse margin dependencies, five Multi-Objective Robustness Indicators based on multi-objective design exploration are presented: The Relative Utopia Index, the Relative Pareto Shape Index, the Relative Compromise Index, the Relative Average Sensitivity Index, and the Average Feasible Variable Range. They aggregate optimality, trade-offs and sensitivity of design configurations. The indicators are applied to a case example, a flat head tank design, to illustrate the effect and inter-dependency of margin specification.Three margin types were identified. The first type affects only the Objective Space size, the second type affects only the Pareto set size and the third type affects Pareto set shape. The third margin type is the most critical as it leads to harder compromises between design objectives later in the design process.KEYWORDS: Design marginsRobust designMulti-objective optimisation AcknowledgementThe authors would like to thank Novo Nordisk for financial support to the DTU-NN Robust Design program.Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1 For a detailed overview of the calculation of mean effective functions fjeff(x). we refer to (Deb and Gupta Citation2006).2 Further work in the area of systematic trade-off mitigation is presented by Sigurdarson et al.
