Structuring servitization-related research

Purpose - The purpose of this paper is to organize and connect past research from different servitization-related scholarly communities. Design/methodology/approach - This study reviews more than 1,000 articles by combining author co-citation and qualitative content analyses. Findings - The structure and boundaries of the field are mapped, and the characteristics of the three identified servitization-related communities are assessed qualitatively. These three communities are product-service systems, solution business, and service science. The findings demonstrate that a narrow range of theories and qualitative methods dominate in existing research. Originality/value - Through the lens of the sociology of science, this review critically evaluates servitization-related research and offers a list of themes that are considered important to the future development of the field. Regarding future research, the main recommendations are as follows: increasing the use of well-established theories from adjacent mature fields, borrowing ideas from different research communities to stimulate knowledge accumulation within and across communities, and reducing the level of description while increasing the number of confirmatory, quantitative, and longitudinal research designs. Finally, the development of formal structures for socialization (e.g. conferences and special issues) could allow the field to achieve a greater degree of scientific maturity and would influence the direction and pace of the development of servitization-related research.fi=vertaisarvioitu|en=peerReviewed

Triple Bottom Line impacts of traditional Product-Service Systems models: Myth or truth? A Natural Language Understanding approach

Currently, there is in the literature a debate concerning the real impact of Product-Service Systems (PSS) models on society. It is now stated that PSS does not necessarily lead to sustainable solutions in practice from a Triple Bottom Line (TBL) perspective. On the other hand, a promising approach, i.e. the Sustainable Product-Service Systems (SPSS) approach, has received attention from scholars within this debate. However, due to the novelty of this discussion, there is insufficient understanding of the synergies and divergences between both approaches regarding the potential to deliver TBL solutions to society. To address these lacks, this study examines the synergies and divergences between PSS and the emerging SPSS to deliver TBL solutions to society. Qualitative and quantitative research approaches were adopted to address the research questions. First, a structured literature review was employed. The literature analysis was segmented into two distinct periods (i.e., first period from 1990 to 2009, and the second period from 2010 to 2021). Next, the Natural Language Understanding (NLU) tools based on Artificial Intelligence (AI) and Neural Networks were applied to analyse the conceptual definitions retrieved from the relevant literature and extract new knowledge regarding both approaches. Third, the patterns of new knowledge were analysed against the literature in the area leading to research findings. Overall, findings indicate that, from a TBL perspective, SPSS is an emerging and promising approach in which the environmental and social dimensions are more salient than in the traditional PSS models. The study also unveils the central concepts related to both approaches in the extant literature. The article extends the current knowledge on PSS and SPSS, guiding the research communities interested in this area and unlocking the present and future challenges towards an effective sustainable-oriented economy. This article is a pioneering study to examine how the PSS and SPSS concepts have advanced towards TBL solutions in society

Regulation of Trade in 3D Printed Goods and WTO Modernization: An Opportunity for New Preferential Rules of Origin

Rules of origin are key legal tools for international trade. While they can pose a puzzle for trade analysts and traders to comprehend, they are not just technical elements of trade. It is important to understand how they function as rules can be utilized by states as non-tariff barriers to trade. This dissertation focuses on preferential rules of origin, which determine if a good receives preferential tariff treatment under a regional or bilateral trade agreement. WTO Members must follow the Common Declaration with Regard to Preferential Rules of Origin, an annex to the Agreement on Rules of Origin. This instrument gives Members sovereignty in designing rules. Prior to and since the formation of the WTO, Members have designed rules that traders find restrictive, especially for trade in inputs. As goods are constructed with parts sourced in global value chains, traders must verify the origin of each part to obtain preferential tariff treatment under an agreement. While digital technology facilitates access to information on rules of origin, traders must still understand and comply with national and regional custom procedures. Digital technology also is the basis for advanced manufacturing, which replaces or complements human labor with digitally based manufacturing techniques, such as additive manufacturing (3D printing). Traders looking to 3D printing to shorten global value chains and reshore manufacturing may face challenges when determining the origin of a 3D printed product, as current rules in trade instruments are based on human-labor manufacturing. Trade analysts have begun to explore rules of origin in the context of 3D printing, including whether the 3D file should be an origin-conferring input. This dissertation takes up these initial assessments and examines the potential outcomes of applying current rules to advanced manufactured goods (which are produced in developed and developing countries) or designing new rules. This investigation requires an exploration of the connections between digital trade and customs duties, the role of state sovereignty in a digital trade environment, and the impact of “deep” policy provisions in agreements on trade of advanced products. Using doctrinal, qualitative, and interdisciplinary research, this dissertation presents the rules under WTO law, the main criteria for determining the origin of a good, legal and economic critiques of preferential rules of origin, rules in the context of services and digital trade, the challenges of applying the origin criteria to 3D printed goods, and recommendations for designing rules for advanced manufactured products and for making rules more trader-friendly. Looking at preferential rules of origin in the context of 3D printing allows us to experiment with modernizing rules to support trade in a digital environment. Identifying aspects of the design and administration of rules where there is a risk for protectionist intervention or a risk of generating more confusion for traders leads us to question how the trade law system should regulate such rules. These considerations also tie into some of the challenges international institutions, especially the WTO, face at this moment: what role should multilateralism play in forming a framework for trade and how can organizations modernize along with technological changes

Product-service system inventory control: manufacturing perspectives

This thesis explores the role of Inventory Control in Product Service System (PSS) applications within manufacturing contexts. This research led to a new approach for dealing with inventory control and contributes to understanding of the PSS paradigm in manufacturing industries. PSS embraces the product and service continuum as one system; meanwhile, Inventory Control has led to substantial improvements in performance across many industries. PSS and Inventory Control have for many years been recognized in the scientific literature and by industry as enablers of manufacturing operations. Most studies in the field of PSS and Inventory Control have only focussed on its individual scenarios; little is known about where the boundaries of PSS should lie as it needs to integrate both external and internal elements in managing PSS Inventory Control. To date, very little research has been reported related to inventory control in product-service systems from manufacturing operations perspectives. Research has been done in three stages: (1) PSS characteristics were synthesised from the literature; (2) current industry example of PSS inventory were investigated through a survey; four case studies were developed; (3) uncertainty elements were identified from the literature related to the current PSS Inventory Control scenario and these were evaluated, developed and validated producing a generic model. The research carried out involved collecting primary data from qualitative research conducted through four case studies with companies in the United Kingdom and Malaysia; and information from secondary sources; utilising techniques such as survey, interview, matrix and modelling language method. This thesis contributes to the current PSS research by developing a generic model of PSS Inventory Control from manufacturing operations perspectives and a PSS Inventory Control (PSSIC) Framework
