Supplier Involvement in Product Development: A Supplier Perspective
- 2022
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis explores the supplier perspective of supplier involvement in product development. Supplier involvement in product development is crucial for many companies to increase resource flexibility, access competence, reduce costs and time to market, among others. The existing literature focuses primarily on the customer perspective of supplier involvement, e.g., challenges and critical factors customers should consider. A few studies have focused on the supplier perspective. This research gap is addressed in this thesis by studying the conditions influencing the suppliers’ involvement in customers’ product development.This thesis explores two research questions: “What are the challenges suppliers experience when being involved in customers’ product development?”, and “What mitigating mechanisms and critical factors influence suppliers’ involvement in customers’ product development?”. The identified challenges originated [FF1] both from the customer and the supplier, indicating that both types of challenges must be focused on. The study also identified interdependencies between the challenges, implying that one challenge may lead to the occurrence of other challenges. The study suggests mitigating mechanisms to deal with the identified challenges. The identified critical factors influenced both the efficiency and effectiveness of supplier involvement in product development, e.g., lead-time, development cost, product quality, and cost. The study indicates that adopting a dual perspective and considering the challenges and critical factors for both the customer and the supplier, can support the involved supplier. The results build on findings from a case study including four SMEs.

- Ships are complex technical systems resulting from large scale and scope projects in which integration plays a key role, particularly because trade-offs have to be made between conflicting objectives. Merchant ships are usually built with a perspective of twenty-five years of service. Ship owners detail their requirements and ship specifications in line with their strategy to remain competitive on specific segments of the shipping markets. Ships serve and organize global trade flows. The rise in environmental regulations and technological changes generate unprecedented uncertainties for ship owners. Ships do not follow the usual systems engineering process, as there is no full-scale prototyping. Rules and standards deeply influence the design of ships and limit the possibilities to 'think outside the box'. The purpose of this paper is to present environmental drivers relating to the operation of the ship which have, or will have, an influence on the way it is designed.

Konferensbidrag (refereegranskat)abstract
- The need for material circularity and sustainability is not limited to human activities on Earth and in fact, has broad implications for the utilization of outer space. With the increased digitalization, global location and observation needs, and connectivity demands for Earth applications, an ever-growing number of spacecrafts being launched into an already “crowded” orbital space at the fast-growing risk of collisions. Sustainability, stewardship, and circularity have been identified as key concepts and enablers for the save and long-term utilization of outer space. However, as research projects related to space sustainability, recycling of spacecraft materials, and space debris mitigation gain traction, a mutual understanding of definitions and concepts is missing and the prospects and viability of circularity in space are unclear. This research attempts to fill this gap with an investigation into the possibilities to re-use spacecraft materials as an alternative to its complete disposal. A review of circularity and sustainability definitions is conducted, and this paper makes an initial effort to examine and map requirements for re-manufacturing, refurbishment, and the re-use of spacecraft materials. A literature review is conducted to identify fundamental concepts to enable circularity. This research reviews best practices and approaches in areas like aviation, electronics, and car manufacturing to thoroughly examine similarities and to create a mapping for the space sector. Following this cross-industry approach, the research surveys academic and industrial topics like spacecraft and satellite mission design, business models and product innovation, and entrepreneurship and space ecosystems to find common patterns within sectors and activities. The paper further presents findings and a preliminary roadmap and future research topics related to circularity in space.

Qualification Aspects in Design for Additive Manufacturing : A Study in the Space Industry
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this research is to further the understanding of implications for product development and qualification when introducing additive manufacturing (AM) in the context of the space industry. Increased availability of AM machines and alluring potentials such as design freedom and cost-efficient product development and manufacturing has led to a rapid growth in the use of AM. However, the implementation of AM is hampered by lack of process understanding, implying uncertainties for engineers on how to design products for AM. Furthermore, the AM process chain (including e.g. post-processes) is not sufficiently developed and understood, adding further uncertainties. These uncertainties are a challenge when developing products for space applications, especially if they are critical for mission success and hence not allowed to fail. Such products and their manufacturing processes have to comply with strict requirements on verifying performance, quality, and reliability, i.e. product and process qualification. The purpose of this research is to investigate how qualification is addressed during product development in the space industry in order to find improved ways for engineers to explore the capabilities of AM to better understand its possibilities and limitations. The research is specifically focused on the use of powder bed fusion processes by companies developing and manufacturing sub-system components for space applications. It is limited to the manufacturing of components on Earth for use in space. The research approach is qualitative. Five studies provide the empirical foundation for the thesis, in which a total of four companies are included. In particular, one of the companies is studied in-depth, including a development project for a critical AM product. Individual interviews, workshops and focus groups are used for data collection. Furthermore, the in-depth study is based on a longitudinal presence at the company, providing the opportunity to gather data from project meetings and discussions. Collaborative action research with three of the companies provides a research setting to study the development of three AM products (of which the in-depth study is one) and how uncertainties related to the AM process can be addressed. Four aspects of how to address product qualification in Design for AM are deduced: (i) AM knowledge should be built through application-driven development processes, (ii) qualification should be accounted for early and to a larger extent, (iii) suitable and acceptable requirements should be defined through collaboration, and (iv) rapid manufacturing should be utilised to evaluate critical uncertainties. To support engineering teams on how to address these aspects, this thesis presents two contributions to the design field. The first is a design process utilising AM Design Artefacts (AMDAs) to identify, test and evaluate the AM-related uncertainties that are most pressing for a product. Through the iterative use of AMDAs, products designs are successively evolved, enabling a design which meets process capabilities and fulfils product requirements. The AMDA design process is part of the second contribution, a Design for Qualification framework that encourages a qualification-driven development approach for AM products. The framework includes six design tactics that provide guidance for its implementation. The tactics encourage an application-driven development process where qualification is considered early, and where successive steps are taken towards a thorough AM process chain understanding. The framework is designed based on the studied cases, and future research should focus on developing the framework and tactics further to facilitate implementation and wider applicability.

- Metal cutting industry, a key sector in manufacturing, is grappling with the transition to a "net-zero industry" to mitigate climate change and reach sustainable practices. Rare and exclusive materials make recycling and reusing cutting tools more pressing and necessitate efficient circular material flows. The purpose of this research is to explore how collaboration can facilitate circularity in the cutting tool industry. It examines the involvement of stakeholders and their roles in achieving a circular lifecycle for cutting tools. To investigate the interaction between metal cutting tools suppliers and Small and Medium-sized Enterprises (SMEs), this study used a mixed-methods approach that includes data from literature, interviews, and document study. Empirical data is gathered to investigate the factors driving circularity and to identify important participants in the lifecycle of cutting tools. The study revealed challenges to the current situation including underutilization of tools due to the absence of a standardization process and subjective operator judgment, as well as lack of traceability of the tools both internally at SMEs and between the stakeholders. Moreover, by mapping the current actors, the study found cutting tool traceability, undirected decision-making throughout tool lifecycles, and limited awareness of circularity dimensions are key challenges. To handle these challenges. 9Rs circular economy framework used to investigate the possible role of collaboration emerges as a vital enabler for circularity, with SMEs playing a significant role. Moreover, the involvement of machine operators, often overlooked actors, is found to be crucial in influencing circular outcomes. Digital solutions and collaborative strategies that involve CNC machine suppliers and intermittent refurbishing business are pivotal in overcoming the challenges identified, namely, traceability and human subjectivity in tool condition assessment. The study demonstrates that technology providers, intermediary refurbishing businesses, SMEs and other stakeholders operating in the metal cutting tools sector must be involved throughout their lifetime to avoid suboptimal results, exchange information, and inspire industrial actors to support the circular economy.

Tidskriftsartikel (refereegranskat)abstract
- Global businesses are transforming towards capturing more value from services, a business model transition called servitization. Digital servitization can help create and maintain a competitive advantage, as well as offering opportunities to tackle major challenges related to environmental pressures and rapidly changing market conditions. This study aims to bridge the gap between the theory of digital servitization and its implementation in the maritime shipping sector. This paper presents a multi-case study that explores the status, perceived challenges, and enablers for the adoption of digital servitization. Empirical data were collected from interviews with 13 companies and analyzed using the PESTEL and DPSIR frameworks. The results are presented across three categories based on the PESTEL framework: organizational context, global priorities, and sustainability. This study contributes to theory by providing empirical insights from the status of digital servitization in the maritime shipping industry. Also, it identifies challenges and needs that can support the transition towards digital servitization and the development of more sustainable solutions. Future research avenues are suggested to advance digital servitization in other industrial sectors.

Konferensbidrag (refereegranskat)abstract
- Service-based business models have attracted growing interest as means to capture sustainable value. There is still unclear terminology and lack of understanding on how servitization can locate sustainability as central value. The purpose of this study is to consolidate the terminology and methods for servitization, to identify factors and elements that contribute to a sustainability perspective. The followed methodology includes a comprehensive literature review, further analyzed through a conceptual framework using an evidence-based approach. The findings of this study will clarify existing terminologies and frameworks while supporting the development of service-based business models that avoid the sustainability paradox of servitization.
