A Knowledge-Based Method for Rapid Design Concept Evaluation

Abstract

Concept generation is one of the most critical steps in product design process. Recently, several computational tools for automatically generating design concepts were developed, which can generate a big number of design concepts. This brings a new challenge to traditional expert-based design concept evaluation methods since experts are not capable of evaluating a large number of design concept in a short time. Therefore, this work develops a knowledge-based method to roughly evaluation design concepts and elect a small number of design concepts for expert-based evaluation. In the proposed method, a knowledge base containing 100 design concepts extracted from existing products is constructed, and four features, including Number of Function (#F), Function Compatibility Index (FCI), Function Component Mapping Index (FCMI) and Component Compatibility Index (CCI) are defined for building evaluation models. Based on the knowledge base and features, several computational evaluation models are developed including novelty evaluation model (NEM), feasibility discrimination model (FDM) and feasibility evaluation model (FEM). Empirical results show the proposed method is capable of evaluating design concepts. This work makes twofold contributes to the research community, the first is a manually constructed knowledge base is published, while the second is four features are defined and used to define design concept evaluation models.

Z-preference-based multi-criteria decision-making for design concept evaluation highlighting customer confidence attitude

“…By comparison, the dynamic definition of  threshold is more flexible to fit different evaluation situations. Thirdly, more MCDM models, even neural networks [53], machine learning model [54] and knowledge-based model [55] can be applied into Z-CDCE-α to satisfy the requirements from more complex design evaluation tasks with more evaluation criteria and more alternatives to be evaluated.…”

Ferramentas de autoria BIM na concepção de projetos de arquitetura

“…Houve, neste sentido, uma evolução dentro das discussões teóricas que partiram do conceito de forma para chegar ao conceito de "formação" -ou geração de forma (OXMAN, 2006. KHAN;AWAN, 2018;HAO et al, 2019), substituindo de algumas maneiras os processos cognitivos tradicionais de interação visual com o croqui (OXMAN, 2006).…”

Design Ontology Supporting Model-Based Systems Engineering Formalisms

“…6(A Five MBSE languages were developed to evaluate whether the ontology could provide enough information for the MBSE model constructions. 4 As listed in Table III, metamodels of five general MBSE languages were built to compare four existing tools. From the results, the ontology could formalize almost all the metamodels of the related languages.…”

“…Thus, it is critical that participants of the MBSE lifecycle work to ensure the completeness and consistency of the data that fuel decision-making and engineering task implementation. Based upon on an AI-driven data exchange, the knowledge management of the future aims to provide the required information to stakeholders whenever (or even before) they need it [3].…”
