    The development of knowledge-shelf to enable an effective set-based concurrent engineering application
    (Inderscience, 2020-11-11) Suwanda, Supriana; Al-Ashaab, Ahmed; Beg, Najam
    This paper presents the development of knowledge-shelf (K-shelf) concept to enable set-based concurrent engineering (SBCE) application via knowledge provision. Three main outcomes are presented: 1) concept of the K-shelf in supporting designers throughout SBCE process; 2) demonstrates the concept via web-based software; 3) an industrial case study of surface jet pump (SJP) is also presented to validate the K-shelf concept and its software demonstrator. The K-shelf capabilities of capturing and storing design rationale in a well-structured manner and to support the comparisons among set of design solutions are the main focus of this paper.

    The development of knowledge-shelf to enable an effective set-based concurrent engineering application.
    (Cranfield University, 2019-04) Suwanda, Supriana; Al-Ashaab, Ahmed; Ip-Shing, Fan
    This research thesis presents the development of the Knowledge-Shelf (K-Shelf), a novel knowledge environment concept to support designers throughout Set- Based Concurrent Engineering (SBCE) application. The K-Shelf concept introduces a baseline model to understand the dimensions of knowledge environment in SBCE application as well as its synthetisation with acclaimed SBCE process model as the contribution to knowledge. The K-Shelf concept incorporates three steps of Knowledge Life Cycle (KLC) that comprises of knowledge capture, knowledge representation and knowledge provision. The K- Shelf concept also has three capabilities that supports the set of conceptual design generation, dynamic knowledge capture of design rationale with 5 Whys approach and the comparisons among set of design solutions with Trade-Off Curve (TOC) visualisation. To demonstrate these capabilities, a web-based software is developed based on Rapid Application Development (RAD) approach. Rigorous research methodology is employed to develop the K-Shelf concept. A systematic literature review is applied to capture the current approaches of knowledge environment in SBCE application. Two industrial case studies of Surface Jet Pump (SJP) and Brake Pedal Box (BPB) are presented to validate the K-Shelf concept. Furthermore, two expert judgements were also obtained. Thus, it was established that the K-Shelf is a knowledge environment to enable an effective SBCE application.

    The development of Knowledge-Shelf to support the generation of a set-based design of Surface Jet Pump
    (World Scientific and Engineering Academy and Society (WSEAS), 2016-12-31) Suwanda, Supriana; Sobun, Noodhir S.; Al-Ashaab, Ahmed; Khan, Muhammad S.; Rehman, Abdullah Rehman; Beg, Najam
    Set-based Concurrent Engineering (SBCE) is advocated in order to provide an environment where design space is explored thoroughly leading to enhanced innovation. This is achieved by considering an alternative set of solutions after gaining knowledge to narrow down the solutions until the optimal solution is reached. Knowledge provision is essential in SBCE application. Hence there is a need for a tool that provides appropriate knowledge environment to enable SBCE and supports it in taking right decisions. At the same time there is a need to capture the rationale of the alternative design decisions taken during the process of narrowing down the set of the design in the SBCE environment. These decision rationales constitute important knowledge to be re-used in developing new products. In this research the tool designed to address this research rationale is called Knowledge-Shelf (K-Shelf). This paper and its outcome serve the groundwork for the development of K-Shelf software that captures knowledge and in generating the first design set in SBCE environment based on previous knowledge documented. This paper is a collaborative work from a case study of Surface Jet Pump (SJP) between the LeanPPD research group in Cranfield University and Caltec Ltd, a company that provides engineering solutions to the oil and gas industry. The K-Shelf was developed using rapid web application development tool - Oracle APEX
