Journal article (peer-reviewed)abstract
- Our life is strongly linked with the usage of natural resources. With increase in world population and welfare there is an increasing global demand for raw material. Energy is a necessity in everyday life and is often generated using non-renewable natural resources which are finite. Manufacturing is one of the largest energy and material resource consumers. There is great concern about minimising consumption of energy in manufacturing industry to sustain the natural carrying capacity of the ecosystem. This is one of the challenges in today’s industrial world. The paper presents the application of system dynamics theory for modelling and simulation of complex manufacturing processes. The simulations help to understand the intricate nature of the interrelation of process parameter and to make sound decision about minimising the energy losses. Two case studies are presented, one in cylinder head casting processes and the other in crankshaft machining. The developed models provide an insight into how to select critical operations and to identify the effect of various parameters on the energy consumption. Also, the models help to understand how changes of parameters over time affect the behaviour of energy changes. The outcome of this research enables the company to identify potential avenues to minimise energy usage and offers a decision support tool.

Approaching digital transformation in the manufacturing industry challenges and differing views
- 2023
-
In: International Journal of Manufacturing Research. - 1750-0591 .- 1750-0605. ; :4, s. 415-433
-
Journal article (peer-reviewed)abstract
- In order to support manufacturing companies in their digital transformation, challenges and views of the term 'digital transformation' need to be identified since digital transformation is considered a source of competitive advantages. Therefore, this paper aims to explore the challenges and differing views of digital transformation in the manufacturing industry. A case study was conducted in collaboration with four Swedish manufacturing companies. The results were then mapped into categories of three dimensions (people, process and technology), indicating that digital transformation can have different meanings within a company. We conclude that the term 'digitalisation' is more frequently used in the manufacturing industry than 'digital transformation' and identified challenges relate to lack of best practice for digital transformation, degree of standardisation and therefore affects the workload and limits the possibilities of transferring technical solutions between factories. Our findings are relevant to operations managers and other interested in digital transformation.

Integration of Augmented Reality Smart Glasses as Assembly Support : A Framework Implementation in a Quick Evaluation Tool
- 2023
-
In: International Journal of Manufacturing Research. - : InderScience Publishers. - 1750-0591 .- 1750-0605. ; 18:2, s. 144-164
-
Journal article (peer-reviewed)abstract
- Augmented reality smart glasses (ARSG) have been successfully used as operator support in production. However, their use is not yet widespread, likely in part due to a lack of knowledge about how to integrate ARSG into production. This lack of knowledge can also make it hard to estimate whether this is a worthwhile investment. Our solution is to provide an online evaluation tool to help production planners estimate the likelihood that ARSG will be worth the investment cost in specific production cases. Based on a strawman design, multiple design iterations were followed by a pilot test performed by participants from different manufacturing companies involved in planning production for operators. A Likert scale survey was used to evaluate the tool. The results show a slightly positive evaluation of the tool with suggestions for improvement, including widening the scope and granularity of the tool. Future works include further iterations and case studies.

What guides information consensus? Approaching the reduction of equivocality in process innovations
- 2020
-
In: International Journal of Manufacturing Research IJMR. - 1750-0591 .- 1750-0605. ; 15:1, s. 73-89
-
Journal article (peer-reviewed)abstract
- This study investigates the achievement of information consensus and the reduction of equivocality in process innovations. Drawing on the operations management literature, a new framework to guide information consensus in the reduction of equivocality in process innovations is proposed. The analysis is based on a real-time case study in the heavy vehicle industry. The results show that information consensus is not achieved by a single event, but active work towards this goal is necessary, and a clear set of pre-requisites is needed for achieving information consensus. The concepts of strategic objective, decision areas, and external and internal fit are identified as pre-requisites for achieving information consensus about the purpose, characteristics, and functionalities of process innovations.

-
In: International Journal of Manufacturing Research. - : InderScience Publishers. - 1750-0591 .- 1750-0605. ; 18:1, s. 28-49
-
Journal article (peer-reviewed)abstract
- This paper presents 'virtual collaborative robot', a virtual reality platform for designing and evaluating collaboration between operators and industrial robots. Within the platform, human-robot collaboration scenarios can be created and a user can interact with a robot without the safety risks that might arise with physical industrial robots. In an initial evaluation of the platform a scenario was implemented combining speech recognition, haptic control, and augmented reality to assemble a car model. The results from this evaluation indicate that the suggested platform can be used to successfully test new applications with the standard equipment of virtual reality headsets.

Two sides of a token : coordinating demand and supply at furniture wholesaler
- 2012
-
In: International Journal of Manufacturing Research. - : Inderscience Publishers. - 1750-0591 .- 1750-0605. ; 7:2, s. 101-122
-
Journal article (peer-reviewed)abstract
- This research work investigates the occurrence of Demand-Supply Chain Management (DSCM) components in a Swedish furniture wholesaler that sources most of its products from China. Three of the eight main components of DSCM were identified in the case company and one component was not fully applicable. The case shows possible caveats of being demand-driven and highlights the need to balance demand and supply sides simultaneously. During economic crisis years 2008-2009, business has experienced extraordinary decline in sales and profitability, while holding considerable amount of inventory at hand. In the long term, supply chain strategy relying on Chinese manufacturing could face increasing challenges in total costs owing to currency changes, transportation costs increase and environmental regulation.

Reproducible decision support for industrial decision making using a knowledge extraction platform on multi-objective optimization data
- 2023
-
In: International Journal of Manufacturing Research. - : InderScience Publishers. - 1750-0591 .- 1750-0605. ; 18:4, s. 454-480
-
Journal article (peer-reviewed)abstract
- Simulation-based optimisation enables companies to take decisions based on data, and allows prescriptive analysis of current and future production scenarios, creating a competitive edge. However, effectively visualising and extracting knowledge from the vast amounts of data generated by many-objective optimisation algorithms can be challenging. We present an open-source, web-based application in the R language to extract knowledge from data generated from simulation-based optimisation. For the tool to be useful for real-world industrial decision-making support, several decision makers gave their requirements for such a tool. This information was used to augment the tool to provide the desired features for decision support in the industry. The open-source tool is then used to extract knowledge from two industrial use cases. Furthermore, we discuss future work, including planned additions to the open-source tool and the exploration of automatic model generation.

Optimisation of Robotised Sealing Stations in Paint Shops by Process Simulation and Automatic Path Planning
- 2014
-
In: International Journal of Manufacturing Research. - 1750-0591 .- 1750-0605. ; 9:1, s. 4-26
-
Journal article (peer-reviewed)abstract
- Application of sealing materials is done in order to prevent water leakage into cavities of the car body, and to reduce noise. The complexity of the sealing spray process is characterised by multi-phase and free surface flows,multi-scale phenomena, and large moving geometries, which poses great challenges for mathematical modelling and simulation. The aim of this paper is to present a novel framework that includes detailed process simulation andautomatic generation of collision free robot paths. To verify the simulations, the resulting width, thickness and shape of applied material on test plates as a function of time and spraying distance have been compared to experiments. The agreement is in general very good. The efficient implementation makes it possible to simulate application of one meter of sealing material in less than anhour on a standard computer, and it is therefore feasible to include such detailed simulations in the production preparation process and off-line programming of the sealing robots.

Comparing quantifiable methods to measure complexity in assembly
- 2014
-
In: International Journal of Manufacturing Research. - 1750-0591 .- 1750-0605. ; 9:1, s. 112-130
-
Journal article (peer-reviewed)abstract
- In order to measure complexity and stay competitive, manufacturing companies need to be able to quantify production complexity. For this reason, two methods were developed within the context of two concurrent research projects are compared: the Belgian Complexity Calculator, CXC, measures objective complexity and the Swedish Complexity Index, CXI, focuses on subjective complexity, as experienced by operators in the stations. This paper presents a comparative analysis of the two methods by comparing them to seven relevant existing quantitative methods and by examining results from case studies. It is observed that the two methods can be used as a compliment to one another, where CXC can be used for scanning data automatically CXI can be used for in-depth analysis. In addition, the comparison of existing methods provides insight on how to measure complexity depending on need and scope.

- 2020
-
In: International Journal of Manufacturing Research. - : Inderscience Enterprises Ltd.. - 1750-0591 .- 1750-0605. ; 15:1, s. 3-21
-
Journal article (peer-reviewed)abstract
- CompleXity index (CXI) is a method that measures perceived production complexity. CXI was applied in the assembly and material-handling department at a manufacturer in the automotive industry, followed by workshops. The aim of the article was, based on the results, to investigate if CXI could be used to capture and transmit a current situation and be used by the operators and managers for improvement work. A high CXI level was measured for most of the production areas. The areas were mainly perceived as complex due to work variance and station design. The workshops revealed that the operators felt identified with the results and thought the method could be used to discuss their situation in detail.

In: International Journal of Manufacturing Research. - : InderScience Publishers. - 1750-0591 .- 1750-0605. ; 16:3, s. 217-240
-
Journal article (peer-reviewed)abstract
- Many industrial challenges can be related to the setup of manufacturing plants and supply chains. While there are techniques available for discrete event simulation of production lines, the opportunities of applying such techniques on higher manufacturing network levels are not explored to the same extent. With established methods for optimisation of manufacturing lines showing proven potential in conceptual analysis and development of production lines, the application of such optimisation methods on higher level manufacturing networks is a subject for further exploration. In this paper, an extended aggregation technique for discrete event simulation of higher level manufacturing systems is discussed, proposed, tested, and verified with real-world problem statements as a proof of concept. The contribution of the new technique is to enable the application of DES models, with reasonable computational requirements, at higher level manufacturing networks. The proposed technique can be used to generate valuable decision information supporting conceptual systems development.

Managing the core plant role-key prerequisites from an operations perspective
- 2020
-
In: International Journal of Manufacturing Research. - : Inderscience Enterprises Ltd.. - 1750-0591. ; 15:1, s. 90-106
-
Journal article (peer-reviewed)abstract
- A core plant should be a centre of excellence, have a central role for knowledge creation, and ensure that the latest knowledge is diffused in the organisation's production network. Core plants can yield a range of benefits, such as increased resource efficiency and decreased costs in the production network. However, core plants face immense challenges in performing their roles, given the different interests of the different stakeholders that need to be satisfied. We use data gathered from an in-depth study of six core plants in Sweden to analyse the prerequisites. We conclude that the core plant prerequisites are influenced by human, organisational, and technological aspects, i.e., successful development of core plant capabilities can only be achieved if all the three components are considered together. Our findings are relevant to operation managers, plant managers, and others interested in developing and maintaining core plant excellence.

Ergonomics analysis in a virtual environment
- 2007
-
In: International Journal of Manufacturing Research. - : InderScience Publishers. - 1750-0591. ; 2:2, s. 198-208
-
Journal article (peer-reviewed)abstract
- Simulation can support the design of an ergonomic workplace by enabling early assessment of ergonomic conditions in a virtual environment. An important feature is the possibility to study alternative solutions or the effect of improvements from an ergonomics perspective. To be able to conduct an efficient and reliable evaluation in a virtual environment, an objective analysis method is essential. Such an analysis method should be integrated in the simulation software, and support a company's everyday ergonomics work process. In order to gain from existing ergonomics knowledge within a company, the possibility to implement such wisdom in the current simulation software becomes important. This paper presents an implementation work done with the purpose of integrating an established ergonomics work process into a virtual environment. It describes the benefits of an ergonomics work process where simulation and evaluation at early stages of a design process are key factors. The paper will also describe the integration process, i.e., the technical issues as well as the change in work methods.

Journal article (peer-reviewed)abstract
- In this paper, the temperature measuring tool based on NiCr/NiSi thin film thermocouple is developed. 6,061 aluminium alloys is selected as the experiment object. Based on the cutting area temperature result during field test, the central composite design is utilised, which contains the parameters of cutting speed, feed rate and cutting depth. Regarding each parameter, three levels are selected and then the second-order regression equation between cutting area temperature and three cutting parameters is established. The data of experimental measurement corresponds well with the mathematical prediction, which confirms that the experimental and mathematical methods are valid in the research on cutting area temperature.

Matching supply chain strategy with business strategy and the results of a mismatch
- 2012
-
In: International Journal of Manufacturing Research. - : Inderscience Publishers. - 1750-0591. ; 7:2, s. 181-197
-
Journal article (peer-reviewed)abstract
- Recent research suggests that supply chains should be demand driven, as this allows them to better exploit differentiation opportunities. Application of this theory is, however, not straightforward, as improper implementation can cause rapid escalation of inventory levels and unit costs. Using the case study method, this research aims to highlight these problems, and to provide deeper knowledge about how supply processes are affected by a consumer-focused business strategy. Apart from identifying the problems that may occur when attempting to be more market-driven, e.g., reduced supply chain performance due to product proliferation, this research also identifies some appropriate means to overcome them, including postponement and differentiated sourcing.

Energy model for motion planning of 2D-belt press line tending robots
- 2020
-
In: International Journal of Manufacturing Research. - : Inderscience Enterprises Ltd.. - 1750-0591. ; 15:1, s. 52-72
-
Journal article (peer-reviewed)abstract
- A current trend in production is to reduce energy consumption where possible not only to lower the cost but also to be a more energy efficient entity. This paper presents an energy model to estimate the electrical energy consumption of 2D-belt robots used for material handling in multi-stage sheet metal press lines. An estimation of the energy consumption is computed by the proposed energy model based on the robot components’ specifications, the robot path and trajectory. The proposed model can predict the energy consumption offline by simulation, and thus, before installation, avoiding the need for physical experiments. It is demonstrated that it can be used for predicting potential energy reductions achieved by optimising the motion planning. Additionally, it is also shown how to investigate the energy saving achieved by using mechanical brakes when the robot is idle. This effectively illustrates the usefulness of the proposed energy model. © 2020 Inderscience Enterprises Ltd.

Influence of cutting speed and tool wear on vibrations and process stability when turning Inconel 718 with PCBN tools
- 2014
-
In: International Journal of Manufacturing Research. - 1750-0591. ; 9:2, s. 173-193
-
Journal article (peer-reviewed)abstract
- Results of the study of cutting speed and tool wear influence on the vibrations and their nature during machining superalloy Inconel 718 with low cBN content (cBN-L) and binderless pcBN (bcBN) tools are presented. Cutting speed was varied from 2 to 14 m/sec while other cutting conditions were constant. The process evolution was studied with the wavelet transform of tool acceleration spectra. Behaviour of the dynamic system was found to vary with the cutting speed and the specifics of tool wear. It is shown that machining with bcBN tools was accompanied by appearance of significant vibration when cutting speed exceeded 5 m/sec, but the machining with cBN-L was characterised by the suppression of vibrations over the entire speed range. This was related to the difference of tool microgeometry development during the course of wear. The wear of bcBN tools, in contrast to cBN-L, was characterised by merger of crater and flank wear and formation of negative clearance angle. Such difference results in an increase of cutting forces 2-4 times as compared to cBN-L tools. Estimation of dynamic stability by 0-1 test confirmed the process instability when turning with bcBN tools at cutting speeds higher than 8 m/sec which concurs with chatter appearance.

A procedure to fully control and trace the weld quality for laser-arc hybrid welding under production conditions
- 2014
-
In: International Journal of Manufacturing Research. - 1750-0591. ; 9:1, s. 92-111
-
Journal article (peer-reviewed)abstract
- Hybrid welding combining a laser beam with a MIG/MAG-arc has high potential to fill joint gaps and to shape the weld surface. The geometrical variations and the oxidation of the joint edges can have significant influence on the resulting weld surface shape and on fatigue life. In the presented study, edge tolerances such as edge mismatch were measured. By consequent scanning of the tolerances, high speed imaging of the melt pool flow dynamics and scanning of the resulting weld surface profile, a systematic identification and explanation of the weld quality on the joint edge conditions can be achieved, even for complex products in rough industrial environment. A corresponding general procedure is presented. From a case study, the limits of quality aspects such as undercuts were quantitatively identified and qualitatively explained.Copyright

Journal article (peer-reviewed)abstract
- Nowadays, product-mix in small batches contributes to shop floor uncertainties, whereas distributed resources are handled collaboratively during assembly planning. There is a growing need to develop methods that can increase adaptability and flexibility in dynamic and collaborative job-shop assembly floors. Based on our previous work on an assembly planning framework using Function Blocks (FBs), a novel approach to assembly planning and control is developed, which enables adaptive decision making besides effective plan execution. Following our previous work, this paper reports the latest development of design and simulation of an FB communication network in Matlab-Simulink environment, and validates the methodology through an example.

- 2014
-
In: International Journal of Manufacturing Research. - : Inderscience Enterprises Ltd.. - 1750-0591. ; 9:4, s. 429-447
-
Journal article (peer-reviewed)abstract
- Standardised information modelling is currently an important solution of enhancing the interoperability of computer-aided technology (CAx) systems in the manufacturing industry. The success of this solution is critically dependent on the complexity of data structure and implementation methodology. This study presents development architecture, STEP toolbox, which enables users to implement information standards via a simplified process with minimised knowledge requirements. This study starts with an analysis of relevant user groups for different types of tasks and knowledge requirements. Then STEP toolbox is presented as the simplified development architecture that consists of conceptual modelling and an object-oriented application programming interface (API). It is more convenient for typical developers than the conventional implementation methodology. Based on results from test cases for implementing three prototypes, a two-month learning process required for average developers of the information standards is expected to be eliminated.

- 2023
-
In: International Journal of Manufacturing Research. - : InderScience Publishers. - 1750-0591. ; 18:4, s. 366-391

Research review (peer-reviewed)abstract
- Reconfigurability is widely acknowledged as a foundation for achieving sustainable manufacturing, while also being an enabler for establishing circular manufacturing. However, further clarifications of how reconfigurable manufacturing can support sustainable manufacturing are necessary. Thus, there is a need to further investigate how reconfigurability can help companies in achieving sustainable manufacturing and to identify future research directions. In this paper, a literature review was conducted to categorise, describe, and summarise the previously conducted research on reconfigurable manufacturing in relation to sustainability. The literature review was conducted in the database Scopus and 265 papers were initially reviewed. After excluding papers not fulfilling the inclusion criteria, 79 papers were analysed in detail using five different categorisations. Based on these categorisations, the previously conducted research on sustainability and reconfigurable manufacturing was analysed. Several frequently discussed sustainability focus areas were identified and described, as well as suggestions of future research directions.

An integrated cost model for metal cutting operations based on engagement time and a cost breakdown approach
- 2017
-
In: International Journal of Manufacturing Research. - 1750-0591. ; 12:4, s. 379-404
-
Journal article (peer-reviewed)abstract
- In all manufacturing processes, it is important to determine the costs and their distribution between different sequential processing steps. A cost equation based directly on the losses during manufacturing, such as rejection rate, stops and waste of workpiece materials, also provides a valuable aid in giving priority to various development activities and investments. The present work concerns how a cost model presented earlier for calculating part costs can be developed to describe part costs as a function of the cutting data and tool life time T selected. This enables a tool life model to be a directly integrated into the cost model by use of tool engagement time. The model presented also takes into account the part costs for scrap incurred in connection with forced tool changes. Examples are also given of how the model developed can be used in the economic evaluation of various cutting tools and workpiece materials.

Prediction of the cutting forces in gear hobbing and the wear behaviour of the individual hob cutting teeth
- 2018
-
In: International Journal of Manufacturing Research. - 1750-0591. ; 13:4, s. 342-358
-
Journal article (peer-reviewed)abstract
- In this paper, a mathematical model is presented, by which the cutting forces in a gear hobbing process and the wear behaviour of the hob's all cutting teeth are predicted. The load on each individual hob cutting tooth varies heavily in the gear hobbing process. To predict the cutting force, and subsequently the tool wear, a detailed determination of the chip geometry is needed. The undeformed chip geometry is continuously determined by analytical differential description presented in previous research. In the model all cut chips are determined for the full production cycle of a gear blank, where the gear blank boundaries are considered. Considering the full production cycle is needed to get an understanding of the load the tool will experience and the wear behaviour of the hob teeth.

Robust product sequencing through evolutionary multi-objective optimisation
- 2015
-
In: International Journal of Manufacturing Research. - : InderScience Publishers. - 1750-0591. ; 10:4, s. 371-383
-
Journal article (peer-reviewed)abstract
- This paper describes a study on efficient optimisation of real-world product sequencing problems with the aim of finding robust solutions. Robust solutions are insensitive to unforeseen disturbances in a manufacturing process, which is a critical characteristic for a successful realisation of optimisation results in manufacturing. In the paper, the traditional method of achieving robust solutions is extended by using standard deviation as an additional optimisation objective. This transforms the original single-objective optimisation problem into a multi-objective problem. Using standard deviation as an additional objective focuses the optimisation on solutions that have both high performance and a high degree of robustness (that is, a low standard deviation). In order to optimise the two objectives simultaneously, a multi-objective evolutionary algorithm based on the Pareto approach is used. The multi-objective method for increased robustness is evaluated using both a benchmark problem and a real-world test case. The real-world test case is from GKN Aerospace in Sweden which manufactures components for aircraft engines and aero-derivative gas turbines. Results from the evaluation show that the method successfully increases the robustness while maintaining high performance of the optimisation.

Optimising milled titanium alloy concave surface quality with micro-textured ball-end milling cutters
- 2021
-
In: International Journal of Manufacturing Research. - : Inderscience Publishers. - 1750-0591. ; 16:2, s. 122-134
-
Journal article (peer-reviewed)abstract
- The cutting speed at the lowest point of a ball-end milling cutter is zero, which results in poor workpiece surface quality and serious cutter wear. To alleviate this problem, a micro-texture can be processed on the rake face of a ball-end milling cutter to provide an anti-friction and anti-wear mechanism. The objective of the work reported here is to reduce cutter wear and optimise workpiece surface quality. By using a mathematical model of row spacing to analyse the differential geometric relationship between cutters and surfaces at their contact point, we have been able to obtain optimal cutter orientation. This was verified by simulating concave surface machining. Experiments were then conducted to verify the approach and the results showed that when the cutter orientation is adjusted to its optimum, the surface quality of the workpiece processed by a micro-textured ball-end milling cutter is at its best.

Web-DPP : towards job-shop machining process planning and monitoring
- 2011
-
In: International Journal of Manufacturing Research. - : InderScience Publishers. - 1750-0591. ; 6:4, s. 337-353
-
Journal article (peer-reviewed)abstract
- Outsourcing, joint ventures and cross-border collaborations have led to job environments geographically distributed. Targeting the distributed environment, the web has been widely used for developing collaborative applications due to its platform, network and operating system transparency and easy-to-use interface. Utilising the existing infrastructure, the objective of this research is to develop an integrated Web-based Distributed Process Planning (Web-DPP) system for job-shop machining operations and execution monitoring. Our approach engages a dispersed working group in a collaborative environment, allowing team members to share real-time information through the Web-DPP. This paper presents both the system design specification and the latest development.

In: International Journal of Manufacturing Research. - 1750-0591. ; 9:4, s. 348-368
-
Journal article (peer-reviewed)abstract
- In recent years, cloud manufacturing concept has been proposed by taking advantage of cloud computing to enhance the performance of manufacturing industry. Cloud manufacturing can be perceived as two types, i.e., manufacturing version of computing cloud, and a distributed environment that is networked around manufacturing cloud. This paper discusses manufacturing resources, abilities and relevant essentials from the service-oriented perspective. The functional requirements of a cloud manufacturing environment are also discussed, along with an interoperable manufacturing system framework. Cloud resource integration methods have been developed based on the function block and software agent technologies. It is possible to achieve a collaborative, intelligent, and distributed environment via cloud manufacturing technologies.

Assessment of a cost-model on sustainability for a proposal for a framework for the evaluation of sustainable manufacturing
- 2020
-
In: International Journal of Manufacturing Research. - 1750-0591. ; 15:1, s. 22-51
-
Journal article (peer-reviewed)abstract
- A process-oriented, performance-based cost-model for manufactured parts has been assessed in its ability to capture sustainability. Literature has been reviewed and found 108 sustainability indicators, which have been compared with the input parameters in the cost-model. Based on a gap analysis, a framework for sustainable production evaluation has been developed. The framework considers performance-based production costs of a product, along with overhead costs, and selling price, giving the product surplus. Additionally, there is a spider-web chart of sustainable factors presenting current state and target values of the product's sustainability. The framework has mainly been developed for SME's boards, but also for production managers in larger firms. Hopefully, this framework will help companies assess their sustainability, with respect to economy, the environment and social responsibility, contributing to a small part of the efforts needed to provide a more sustainable world for the future.

How the characteristics of small and medium-sized enterprises influence product-service systems design challenges
- 2023
-
In: International Journal of Manufacturing Research. - : Inderscience Publishers. - 1750-0591. ; :4, s. 434-453
-
Journal article (peer-reviewed)abstract
- Manufacturing companies can contribute to a resource-efficient society by designing product-service systems (PSS). Despite the increased importance of PSS for the manufacturing industry in their efforts to become sustainable, few studies focus on small and medium-sized enterprises (SMEs). The study presented in this article aims to add knowledge on how the characteristics of SMEs influence the challenges SMEs experience when designing PSS. It employs a multiple case study design where data are based on interviews, workshops, and internal archive documents from three contract manufacturing SMEs. The analysis suggests that nine SME characteristics influence the challenges SMEs experience when designing PSS. It also shows that SMEs’ different characteristics influence one or more challenges, and that SMEs have a short-term horizon and a reactive business approach which influences the overall challenge of designing PSS.
