    (World Scientific and Engineering Academy and Society (WSEAS), 2016-12-31) Mohd Maulana, Muhd Ikmal; Flisiak, Jakub Wiktor; Al-Ashaab, Ahmed; Araci, Zehra Canan; Lasisz, Piotr Wojciech; Beg, Najam; Rehman, Abdullah
    Set-Based Concurrent Engineering (SBCE) is an approach that has the capability to improve the efficiencies of the product development process. SBCE provides an environment where design space is explored thoroughly which lead to enhance innovation. This is achieved by considering an alternative set of solutions after gaining the right knowledge to support decision to narrow down the set of solutions until the single optimal design solution is reached. This paper presents a novel application SBCE in order to generate alternative design to enhance the efficiency of the Surface Jet Pump (SJP) in term of its productivity and performance of producing the oil and gas in oil and gas well.

    (Science and Information (SAI) Organization, 2020-05-31) Araci, Zehra Canan; Al-Ashaab, Ahmed; Tariq, Muhammad Usman; Braasch, Jan H.; Emre Simsekler, M. C.
    Organizations invest intense resources in their product development processes. This paper aims to create a knowledge environment using trade-off curves during the early stages of the set-based concurrent engineering (SBCE) process of an aircraft jet engine for a reduced noise level at takeoff. Data is collected from a range of products in the same family as the jet engine. Knowledge-based trade-off curves are used as a methodology to create and visualize knowledge from the collected data. Findings showed that this method provides designers with enough confidence to identify a set of design solutions during the SBCE applications

    Knowledge creation and visualisation by using trade-off curves to enable set-based concurrent engineering
    (Academic Conferences International Ltd, 2016-04-01) Araci, Zehra Canan; Al-Ashaab, Ahmed; Maksimovic, Maksim
    The increased international competition forces companies to sustain and improve market share through the production of a high quality product in a cost effective manner and in a shorter time. Set‑based concurrent engineering (SBCE), which is a core element of lean product development approach, has got the potential to decrease time‑to‑market as well as enhance product innovation to be produced in good quality and cost effective manner. A knowledge‑based environment is one of the important requ irements for a successful SBCE implementation. One way to provide this environment is the use of trade‑off curves (ToC). ToC is a tool to create and visualise knowledge in the way to understand the relationships between various conflicting design parame ters to each other. This paper presents an overview of different types of ToCs and the role of knowledge‑based ToCs in SBCE by employing an extensive literature review and industrial field study. It then proposes a process of generating and using knowledg e‑based ToCs in order to create and visualise knowledge to enable the following key SBCE activities: (1) Identify the feasible design space, (2) Generate set of conceptual design solutions, (3) Compare design solutions, (4) Narrow down the design sets, (5) Achieve final optimal design solution. Finally a hypothetical example of a car seat structure is presented in order to provide a better understanding of using ToCs. This example shows that ToCs are effective tools to be used as a knowledge sou rce at the early stages of product development process.

    Knowledge creation and visualisation by using trade-off curves to enable set-based concurrent engineering applications
    (2017-03) Araci, Zehra Canan; Al-Ashaab, Ahmed
    Inefficiencies that could be avoided during the product development process account for a large percentage of the manufacturing cost. To introduce innovative, high-quality products in a time- and cost-efficient manner, companies need to improve the performance of their product development processes. Set-based concurrent engineering (SBCE) has the capability of addressing this issue if the right knowledge-environment is provided. Trade-off curves (ToCs) are effective tools to provide this environment through knowledge creation and visualisation. However, there are several challenges that designers face during their product development activities such as rework, inaccurate decisions, and failure in design performance, which eventually cause waste. Therefore, the aim of this thesis is to eliminate waste by developing a systematic approach for generating and using ToCs. These then serve as a guide for designers to support their decision-making and achieve an efficient product development performance in an SBCE environment. To achieve this aim, qualitative research methods were employed. Following an extensive literature review, industrial field study and industrial applications, three processes were developed to generate ToCs and validated with five industrial case studies. The process for generating knowledge-based ToCs describes how to create and visualise knowledge that is obtained from historical data and/or experience. This process facilitates the reuse of knowledge about existing products, in order to reduce the requirement for resources (e.g. product development time). The process for generating physics-based ToCs describes an approach to creating knowledge that is obtained from understanding the physics and functionality of the product under development. Thus, the practitioners gain sufficient confidence for identifying a compromise between conflicting design parameters. Finally, the process for using ToCs within the SBCE process model presents a technique to use generated knowledge-based and physics-based ToCs in order to enable key SBCE activities. These activities are (1) Identifying the feasible design area, (2) Developing a design-set, (3) Comparing possible design solutions, (4) Narrowing down the design-set and (5) Achieving the final optimal design solution. For validation, the developed processes were applied in five industrial case studies, and two expert judgements were obtained. Findings showed that ToCs are essential tools in several aspects of new product development, specifically by reducing the lead time through enabling more confident and accurate decisions. Additionally, it was found that through ToCs, the conflicting relationships between the characteristics of the product can be understood and communicated effectively among the designers. This facilitated the decision-making on an optimal design solution in a remarkably short period of time. The design performance of this optimal design increased by nearly 60% in a case study of a surface jet pump. Furthermore, it was found that ToCs have the capability of storing useful data for knowledge creation and reusing the created knowledge for the future projects.

    The set-based concurrent engineering application: a process of identifying the potential benefits in the surface jet pump case study
    (Elsevier, 2017-05-09) Mohd Maulana, Muhd Ikmal I. Bin; Al-Ashaab, Ahmed; Flisiak, Jakub W.; Araci, Zehra Canan; Lasisz, Piotr W.; Shehab, Essam; Beg, Najam; Rehman, Abdullah
    The Set-Based Concurrent Engineering (SBCE) is the methodology that can improve the efficiencies and effectiveness of product development. It is found that the SBCE approach provided a suitable knowledge environment to support decision making throughout the development process. This paper presents the potential tangible benefits gained from the application of the SBCE in an industrial case study of a Surface Jet Pump (SJP) that is used to revive the production of oil/gas from the dead wells. The well-structured SBCE process model and the process of identifying the potential benefits proposed in this paper will clarify the gap in the development of the SBCE in the company. The potential tangible benefits are established in a few key areas such as product innovation, product performance, manufacturing cost, and project success rate.

    Set-based concurrent engineering process model and systematic application on an electronic card reader
    (World Scientific and Engineering Academy and Society (WSEAS), 2021-11-23) Al-Ashaab, Ahmed; Araci, Zehra Canan; Maulana, Muhd Ikmal I. Mohd; Garcia Almeida, Cesar; Young, Steve
    Set-based concurrent engineering (SBCE), also known as set-based design, is a state-of-the-art approach to the new product development process. SBCE, simply, provides an environment where designers explore a wide range of alternative solutions in the early stages of product development. After gaining knowledge, solutions are narrowed down until the optimal solution is ensured. Such an environment saves considerable amount of cost and time while reaching innovation and high quality in the products. However, industrial practitioners seek a clear and systematic application throughout an SBCE process. This paper demonstrates a well-structured SBCE process model and its step-by-step application on a product called “electronic card reader”. Real data is used in the industrial case study. Results showed the benefits of applying SBCE in both the product, and the process of new product development.

    Synthesising knowledge for lean product development process of a low noise jet engine
    (Inderscience, 2021-03-30) Araci, Zehra Canan; Al-Ashaab, Ahmed; Tariq, Muhammad Usman; Braach, Jan H.
    The product development process is one of the most challenging stages of a product life cycle due to several reasons. Having the right knowledge environment during the design process may eliminate the waste of cost and time. The aim of this paper is to demonstrate a case study where designers can investigate the conflicting parameters about a product and make their decisions based on an accurate knowledge environment that is created by trade-off curves. The product in consideration is a turbofan jet engine with a requirement of noise reduction during takeoff while keeping up with high quality standards.

    Trade-off curves applications to support set-based design of a surface jet pump
    (Elsevier, 2017-05-09) Araci, Zehra Canan; Al-Ashaab, Ahmed; Lasisz, Piotr W.; Flisiak, Jakub W.; Mohd Maulana, Muhd I. I.; Beg, Najam; Rehman, Abdullah
    Knowledge has become the most important asset of companies, especially in improving their product development processes. The set-based design approach is an efficient way of designing high quality, optimised designs. However, it requires a proven knowledge environment. Trade-off curves (ToCs) have the capability of providing the right knowledge and displaying it in a visual form. Although there are a few applications of ToCs that have recently been published in the literature, none of them demonstrates an integrated implementation of ToCs throughout the SBCE process. This paper presents the integrated use of ToCs, based on both physics-knowledge and proven knowledge, in order to compare and narrow down the design-set and to achieve an optimal design solution. These are key activities of the SBCE process model. Since an accurate, documented and visual knowledge environment is created by the use of ToCs within SBCE, the integrated approach proposed in this paper plays a vital role in eliminating the need for prototyping and testing at the early stages of product development. The integrated approach was implemented in an industrial case study for a surface jet pump. Surface jet pumps are used to increase the production rate of low-pressure oil/gas wells. It has been found that through ToCs, the conflicting relationships between the characteristics of the product can be understood and communicated effectively among the designers. This facilitated the decision-making on an optimal design solution in a remarkably short period of time. Furthermore, the surface jet pump resulting from the case study achieved an increase of the oil/gas production by nearly 60%.
