Abstract

Companies face pressure to enhance productivity and efficiency while meeting the demands of dynamic markets and global competition. Additive Manufacturing (AM) technology has emerged as an innovative solution with the capability to efficiently create complex geometries and enable design personalization, despite ongoing challenges related to quality, materials, and post-processing. The TRIZ method, as a systematic problem-solving approach, offers innovative solutions by analyzing contradictions in design, which can be applied to AM to optimize processes and products. The Design for Additive Manufacturing (DFAM) approaches leverages AM's layer-by-layer production process to create new, innovative designs. In the context of Concurrent Engineering (CE), the synergy between CE, AM, and TRIZ enables more efficient, innovative, and rapid product development, providing design flexibility, lower production costs, and shorter time-to-market. This combination of strategies offers a significant competitive advantage in the global market.

Abstract

Lean manufacturing is a systematic approach to reduce waste and increase productivity. In its implementation, lean manufacturing is often faced with complexity in its application due to inappropriate decision-making. Therefore, a more structured approach, such as the integration of the Fuzzy Multi Criteria Decision-Making (FMCDM) method, is a solution to assist decision-making within the lean framework and ensure proper lean implementation. This research aims to explore the application of FMCDM by using a Systematic Literature Review (SLR) approach, successfully analyzing 185 articles published between 2000 and 2025 focusing on integrating FMCDM and lean manufacturing. The results of the literature review show that the integration of FMCDM and lean manufacturing is still limited but has increased since 2023, with FMCDM being used for three primary purposes, namely evaluation of factors and risks in lean implementation, selection of appropriate lean tools and strategies, and assessment of lean level. This research identifies research gaps and offers practical recommendations to improve lean manufacturing effectiveness through a more adaptive and structured decision-making approach. Thus, this research is expected to significantly contribute to developing lean manufacturing theory and practice, particularly in FMCDM-based decision-making.

Abstract

Product design has emerged as a crucial element in developing innovative solutions that prioritize not only functionality and aesthetics but also sustainability. The Human-Centered Design (HCD) approach has long been employed to ensure that user needs remain the primary focus throughout the design process. However, global challenges such as climate change, social inequality, and the long-term impacts of products necessitate a more comprehensive approach. Consequently, the concept of Humanity-Centered Design has been developed as an extension of HCD, emphasizing the importance of considering the entire ecosystem, other living beings, and long-term consequences in the product design process. This research utilizes a narrative literature review method to examine the Humanity-Centered Design (HuCD) approach within the context of sustainable product design. The review findings indicate that Humanity-Centered Design introduces five key principles, which include a focus on fundamental issues, a holistic ecosystem perspective, long-term outlook, continuous iteration, and community participation. This approach has been shown to enhance the relevance, acceptance, and sustainability of solutions across various sectors, including health technology, manufacturing, and digital domains.

Abstract

Increased competition in the industry encourages companies to focus on customer satisfaction to maintain competitiveness. The combination of Design for Assembly (DFA) and Design for Serviceability (DFS) methods is a common concern for researchers, especially in product development. This research describes the integration of DFA and DFS methods to solve product problems, starting from the method development stage, the interrelationship between the two methods, etc. The successful application of these methods is evident through high efficiency and improved product quality. Key factors involved management cooperation, use of quality tools, and teamwork. Leading journals highlight product cost reduction through Design for Serviceability and DFA techniques. Emphasis on sustainability, especially by integrating sustainability goals in product design, evidenced positive environmental impact and market response. Research also highlighted the need for identification and prioritisation of customer requirements and optimisation of production process parameters. The integration of modelling methods and design systems, such as in the development of a modelling system for metal casting processes, demonstrated success in achieving effective product development goals. Overall, this research provides an in-depth understanding of the potential and benefits of applying DFA and DFS in efficient, high-quality and sustainable product development, providing a foundation for further development and implementation by practitioners and researchers.

Abstract

The need for electronic devices has become essential for many people. Nearly all households have adopted their use in various functions and forms, which has consequently led to several issues. One such case involves mixer, an appliance specifically used in the culinary field for mixing dough. The research problem focuses on the weakening of the screw joint on the body cover due to strong vibrations and high-frequency usage. Additionally, the screw holes are too deep, making the assembly process difficult. Therefore, product design improvement is required using the Quality Function Deployment (QFD) Phase I and Phase II methods. This study aims to identify the priority of technical characteristics and critical parts in the mixer product using QFD Phase I and QFD Phase II. Technical characteristics refer to the distinctive features of the product that enable it to perform optimally, such as ease of assembly and the number of components relative to their level of complexity. The product’s critical part refers to the most essential and crucial component, namely, the body cover, which has the highest level of assembly difficulty and thus requires immediate improvement. The improvement proposed for the mixer involves changing the type of joint from the current bolt-based design to a snap-fit design, thereby reducing the number of components and assembly time for 2 units and 17,19 seconds respectively,  and enhancing ease of assembly based on the efficiency design calculation by 0,56%.
