A modularized generic product model in support of product family modeling in One-of-a-Kind Production

Abstract

In One-of-a-Kind Production (OKP), a large number of customised product designs and CAD models are produced in order to satisfy a wide variety of customer requirements (CRs). This situation inevitably results in data redundancy when representing product families. Aiming to solve this issue, in this paper, a structured product model, the modularized generic product model (MGPM), is proposed to reduce data redundancy in OKP product family modeling. A function mapping method is proposed to assign functions/subfunctions to their corresponding items in the MGPM which is capable of supporting the conceptual design stage in New Product Development (NPD). Besides, functions allocated to CAD models form the indexes for these models, which improve the efficiency of case retrieval. Finally, to demonstrate the proposed product modeling approach, a case study is carried out on fruit chute products.

Methodology for Early Design Phase Cost and Performance Trade-Off Analysis of a New Variant in a Product Family

“…A big challenge in the formal modeling of a product family is to avoid redundancy in the specification of the product model for each variant. Conventional modeling methods fail to address this problem (Zeng et al, 2014). In particular there is a challenge in combining structural based modeling and feature based modeling.…”

“…In particular there is a challenge in combining structural based modeling and feature based modeling. Amongst various existing solution approaches -for example the Modularized Generic Product Model (Zeng et al, 2014) or by using the UML language (Bonev et al, 2015) -there is no consensus yet. In this paper, a new metamodel is proposed to create a Domain Specific Language (DSL) that is built upon the Eclipse Ecore modeling framework (see https://wiki.eclipse.org/Ecore), which provides a built-in interface for facilitating the interaction with the design end-users.…”
