Ontology-based customer preference modeling for concept generation

Self Cite

Preference is viewed as an outer feeling of a product, also as a reflection of human's inner thought. It dominates the designers' decisions and affects our purchase intention. In the paper, a model of preference elicitation from customers is proposed to build module concepts. Firstly, the attributes of customer preference are classified in a hierarchy and make the surveys to build customer preference concepts. Secondly, the documents or catalogs of design requirements, perhaps containing some textual description and geometric data, are normalized by using semantic expressions. Some semantic rules are developed to describe low-level features of customer preference to construct a knowledge base of customer preference. Thirdly, designers' needs are used to map customer preference for generating module concepts. Finally, an empirical study of the stapler is surveyed to illustrate the validity of module concept generation.

“…Customer preference is of certain relativity and is not absolute [14]. It is changeable relative to time span, scene, and attribute.…”

“…They used a probabilistic approach to elicit customers' latent and subjective preferences requirement and incorporated them into product design. Cao et al 8 put forward that the preference of CR is different and the customer preference model is constructed to analyze CR. Li et al 9 used three types of least squares modeling to obtain CR satisfaction and diverse customer preference requirement.…”

Customer requirement modeling and mapping of numerical control machine

Song

et al. 2015

In order to better obtain information about customer requirement and develop products meeting customer requirement, it is necessary to systematically analyze and handle the customer requirement. This article uses the product service system of numerical control machine as research objective and studies the customer requirement modeling and mapping oriented toward configuration design. It introduces the conception of requirement unit, expounds the customer requirement decomposition rules, and establishes customer requirement model; it builds the house of quality using quality function deployment and confirms the weight of technical feature of product and service; it explores the relevance rules between data using rough set theory, establishes rule database, and solves the target value of technical feature of product. Using economical turning center series numerical control machine as an example, it verifies the rationality of proposed customer requirement model.

“…Many approaches are researched for realizing conceptual design. For example, Cao et al [21,22] presented a port-based ontology modeling method to support product conceptualization. Taking the conceptual design of aircraft as an example, the goal is to generate one or more aircraft concepts which will meet the design specifications.…”

Conceptual Design of Deployment Structure of Morphing Nose Cone

Yan

2013

For a reusable space vehicle or a missile, the shape of the nose cone has a significant effect on the drag of the vehicle. In this paper, the concept of morphing nose cone is proposed to reduce the drag when the reentry vehicle flies back into the atmosphere. The conceptual design of the structure of morphing nose cone is conducted. Mechanical design and optimization approach are developed by employing genetic algorithm to find the optimal geometric parameters of the morphing structure. An example is analyzed by using the proposed method. The results show that optimal solution supplies the minimum position error. The concept of morphing nose cone will provide a novel way for the drag reduction of reentry vehicle. The proposed method could be practically used for the design and optimization of the deployable structure of morphing nose cone.
