- 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.

Tidskriftsartikel (refereegranskat)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

Tidskriftsartikel (refereegranskat)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.

Tidskriftsartikel (refereegranskat)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.

Tidskriftsartikel (refereegranskat)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.

- The aim of this paper is to propose a framework for universal design of manual assembly workplaces. Workplaces that are adapted to different individuals, regardless of gender, language, background and functional variations, also support the fundamental goals of the Industry 5.0 concept and an accessible, safer, productive and error-proof work environment. The study included: 1) a qualitative study on key factors for universal design and comparison with universal design theory; 2) improvement suggestions to the company based on observations, interviews and theory; 3) a framework for universal design. The framework included the following areas: personalisation and context, activities/tasks and output, and methods/standards and factors were suggested so that companies could start their analysis work for the design. The study resulted in new insights and empirics regarding universal workplace design. [Submitted 13 November 2022; Accepted 13 April 2023]

Tidskriftsartikel (refereegranskat)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.

Tidskriftsartikel (refereegranskat)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.

- Industry is foreseeing rapid developments in the ability tocapture data within its manufacturing operations and the interest in methodsfor extracting knowledge from such data is increasing. Through digitalrepresentations of manufacturing operations, future scenarios can be modeledand developed with analysis tools based on simulation in combination withmulti-objective optimisation. The results from such analysis tools may bechallenging to interpret, especially when expanding the scope to searchingfor information patterns. An emerging multi-objective rule extraction method,with the ability to handle discrete input parameters, has been furtherdeveloped towards integration in an intelligent decision support system.

- It is widely recognised that manufacturing companies need to pay attention to sustainability aspects to be competitive. However, there is still no clarity on how to combine requirements for sustainability and profitability to achieve long-Term competitive manufacturing. Furthermore, there is a need for knowledge on how to develop resilient and sustainable production systems. This paper aims to explore the state-of-The art and state-of-practice associated with the development of resilient and sustainable production systems, with a focus on challenges and enablers. To achieve this, a narrative literature review was carried out, combined with results from knowledge creation workshops with five manufacturing companies striving towards resilient and sustainable production systems.

Managing the core plant role-key prerequisites from an operations perspective
- 2020
-
Ingår i: International Journal of Manufacturing Research. - : Inderscience Enterprises Ltd.. - 1750-0591. ; 15:1, s. 90-106
-
Tidskriftsartikel (refereegranskat)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.

Energy model for motion planning of 2D-belt press line tending robots

Ingår i: International Journal of Manufacturing Research. - : Inderscience Enterprises Ltd.. - 1750-0591. ; 15:1, s. 52-72
-
Tidskriftsartikel (refereegranskat)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.

Forskningsöversikt (refereegranskat)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.

Optimising milled titanium alloy concave surface quality with micro-textured ball-end milling cutters
- 2021
-
Ingår i: International Journal of Manufacturing Research. - : Inderscience Publishers. - 1750-0591. ; 16:2, s. 122-134
-
Tidskriftsartikel (refereegranskat)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.

Assessment of a cost-model on sustainability for a proposal for a framework for the evaluation of sustainable manufacturing
- 2020
-
Ingår i: International Journal of Manufacturing Research. - 1750-0591. ; 15:1, s. 22-51
-
Tidskriftsartikel (refereegranskat)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
-
Ingår i: International Journal of Manufacturing Research. - : Inderscience Publishers. - 1750-0591. ; :4, s. 434-453

Tidskriftsartikel (refereegranskat)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.
