Considering the importance of user profiles in interface design
- 2009
-
In: User Interfaces. ; , s. 23-
-
Book chapter (other academic/artistic)abstract
- User profile is a popular term widely employed during product design processes by industrial companies. Such a profile is normally intended to represent real users of a product. The ultimate purpose of a user profile is actually to help designers to recognize or learn about the real user by presenting them with a description of a real user’s attributes, for instance; the user’s gender, age, educational level, attitude, technical needs and skill level. The aim of this chapter is to provide information on the current knowledge and research about user profile issues, as well as to emphasize the importance of considering these issues in interface design. In this chapter, we mainly focus on how users’ difference in expertise affects their performance or activity in various interaction contexts. Considering the complex interaction situations in practice, novice and expert users’ interactions with medical user interfaces of different technical complexity will be analyzed as examples: one focuses on novice and expert users’ difference when interacting with simple medical interfaces, and the other focuses on differences when interacting with complex medical interfaces. Four issues will be analyzed and discussed: (1) how novice and expert users differ in terms of performance during the interaction; (2) how novice and expert users differ in the perspective of cognitive mental models during the interaction; (3) how novice and expert users should be defined in practice; and (4) what are the main differences between novice and expert users’ implications for interface design. Besides describing the effect of users’ expertise difference during the interface design process, we will also pinpoint some potential problems for the research on interface design, as well as some future challenges that academic researchers and industrial engineers should face in practice.

Demand-Supply Chain Management
- 2010
-
Doctoral thesis (other academic/artistic)abstract
- Purpose: This research aims to enhance the current understanding and knowledge of the demand-supply chain management (DSCM) concept by determining its elements, benefits, and requirements, as well as by analyzing key elements of the concept. Methodology: This research has utilized the case study strategy and the survey strategy, however, the case study strategy dominates. The case study research has involved five companies originating from Sweden and the collection of empirical data mainly from in-depth interviews with key persons representing senior and middle management. The survey research targeted the largest firms in Sweden and Finland and empirical data was collected through an online questionnaire. Findings: This research has established that the main elements of DSCM include market orientation, coordination of the demand and supply processes, viewing the demand and supply processes as being equally important, as well as value creation, differentiation, innovativeness, responsiveness, and cost-efficiency in the demand and supply processes. It has also been revealed that the main benefits of DSCM include enhanced competiveness, enhanced demand chain performance, as well as enhanced supply chain performance, while the main requirements of DSCM include organizational competences, company established principles, demand-supply chain collaboration, and information technology support. A key element of DSCM further investigated is differentiation focused supply chain design. It has been shown that these efforts can be organized into a process of five stages. In addition, it is important that this process is addressed in parallel with the new product development (NPD) process, that information is exchanged between them, and that they are directed on the basis of the same segmentation model. Another key element of DSCM further investigated is coordination between NPD and SCM. This research has identified several significant linkages between these management directions, which motivate the use of an integrative NPD process where the NPD functions are aligned with the main supply functions in the company and other sales-related functions supporting the commercialization. A final key element of DSCM further investigated is the significance of regarding the demand processes and the supply processes as being equally important. This research has revealed that logistics outsourcing can be risky, if it results in the supply processes being considered less important. Nevertheless, if senior management regards the outsourced processes as equally important as the in-house processes, the effect of logistics outsourcing on company strategies and direction in SCM could be reduced and logistics outsourcing could instead provide an opportunity to improve the design and differentiation of the supply chain. Research limitations/implications: This research has proposed, described, and further analyzed a demand-supply oriented management approach. Such a management approach stresses that the demand processes and the supply processes have to be coordinated and directed at an overlying level, in order to gain and sustain a competitive advantage in competitive and fragmented markets. This research is mainly explorative in nature, and more empirical data, from similar and other research settings, is needed to further validate the findings. Another limitation of the research is that it is essentially limited to Swedish companies (even if some Finnish companies are involved in the survey), however, many of the case companies have a large international presence and are among the top three in their industries, facts which provide some grounds for generalization. Practical implications: This research provides researchers and practitioners with insights into how to develop a demand-supply oriented business. It shows that companies should organize themselves around understanding how customer value is created and delivered, as well as how these processes and management directions can be coordinated. In order for this to occur, the demand and supply processes must be considered as being equally important and the firm needs to be managed jointly and in a coordinated manner by the demand- and supply-side of the company. It is also important that value creation is considered in both the demand and supply processes. Originality/value: Despite strong arguments from both researchers and practitioners for a demand-supply oriented management approach only a minority of companies appear to have effectively coordinated the demand and supply processes. This might be influenced by the lack of research examining how the demand and supply processes can be coordinated, what benefits can be gained by coordinating them, and what requirements are necessary to succeed. This research contributes by investigating these types of aspects further.

Design-driven innovation : Making meaning for whom
- 2017
-
In: The Design Journal. - : European Academy of Design. - 1460-6925 .- 1756-3062. ; 20:S1, s. S479-S491
-
Journal article (peer-reviewed)abstract
- Design-driven innovation focuses on the innovation of product meanings. This innovation is enabled by integrating knowledge on needs, product language and technological development. So far, it has mostly been studied in contexts where the buyer is the assumed end user. There has been little research about design-driven innovation in other contexts, such as business-to-business and public contexts. Here, companies need to create value for multiple stakeholders. In this study, these are defined as users, buyers and influencers. The aim of this study is to explore how companies consider the different stakeholders in the innovation of product meanings. Two companies participated in a case study. The results demonstrate that both companies mainly focus on addressing needs. However, while one case company prioritizes the perspective from the user, the other focuses more on the buyer. The results illustrate the increased complexity that companies need to manage in design-driven innovation in these contexts.

Testing of the Aerodynamic Characteristics of an Inflatable Airfoil Section
- 2020
-
In: Journal of Aerospace Engineering. - 1943-5525 .- 0893-1321. ; 33:5
-
Journal article (peer-reviewed)abstract
- Inflatable structures are characterized by being light and easy to manufacture and deploy. Hence, they find many applications in aerospace and aeronautical engineering. In this paper, an inflatable segment with a The National Advisory Committee for Aeronautics (NACA) 0021 airfoil cross-section is designed, fabricated, and tested. The geometrical accuracy of the manufactured inflatable segment is measured using laser scanning. Measurements show that the average normalized error of the chord length and thickness are 2.97% and 0.554%, respectively. The aerodynamic behavior of the inflatable segment is then tested in a wind tunnel at different wind speeds and angles of attack. Lift forces are measured using a six-component balance, while the drag forces are calculated from the wake measurements. The lift and drag coefficients of the inflatable section are compared to those of a standard NACA 0021 airfoil. Finally, flow visualization is examined at different angles of attack using two methods: smoke and tufts. Both methods show that flow separation starts at 15° and full stall occurs at 25°. Results indicate that inflatables can find more applications in the design and construction of aerodynamic structures, such as wings.

Safety System for Industrial Robots to Support Collaboration
- 2016
-
In: Advances in Ergonomics of Manufacturing. - Cham : Springer International Publishing. - 9783319416960 - 9783319416977 ; , s. 253-265
-
Book chapter (peer-reviewed)abstract
- The ongoing trend towards manufacturing of customized products generates an increased demand on highly efficient work methods to manage product variants through flexible automation. Adopting robots for automation is not always feasible in low batch production. However, the combination of humans together with robots performing tasks in collaboration provides a complementary mix of skill and creativity of humans, and precision and strength of robots which support flexible production in small series down to one-off production. Through this, collaboration can be used with implications on reconfiguration and production. In this paper, the focus and study is on designing safety for efficient collaboration operator—robot in selected work task scenarios. The recently published ISO/TS 15066:2016 describing collaboration between operator and robot is in this context an important document for development and implementation of robotic systems designed for collaboration between operator and robot.

Gender and entrepreneurship in the horse-related industry
- 2013
-
In: Journal of Business Diversity. - 2158-3889. ; 12:2, s. 75-93
-
Journal article (peer-reviewed)abstract
- In this paper, we examine the horse-related industry in terms of entrepreneurship and gender. Based on reports of the industry, a mapping of the entire sector (N= 7504) and a questionnaire (N=520) we find that the industry is portrayed as female gendered, but dominated by men. However, we also find evidence that the industry is changing gender, as women dominate among younger entrepreneurs. The strongest motives for the horse-related entrepreneurs (regardless of gender) are realizing a dream and being able to combine interest with work. We also found that entrepreneurs in this industry mainly network inside the industry.

In: International Journal of Technology Transfer and Commercialisation (IJTTC). - : Inderscience Enterprises Ltd. - 1470-6075 .- 1741-5284. ; 9:4, s. 306-325
-
Journal article (peer-reviewed)abstract
- China has moved a long way in economic and industrial development during the last decades and has developed into a global player in many industries. With increased knowledge in high-technology industries, China has ambitions to move into sectors that necessitate a high level of research and development, such as the aerospace industry. China is now in the process of establishing a modern aircraft industry based on domestic efforts as well as agreements with foreign partners in the manufacturing of complete aircraft. This paper analyzes what measures have been taken by Airbus in the form of technology transfer and other supportive measures to strengthen its position in the Chinese market. The findings conclude that Airbus’ transfer should be looked upon as a broad spectrum of technology and knowledge transfer, which include aircraft manufacturing technology, as well as cabin crew training centre, establishment of a warehouse and suppliers ”village”, an engineering centre, maintenance and various service functions.

Perceived quality framework in product generation engineering: an automotive industry example
- 2019
-
In: Design Science. - : Cambridge University Press (CUP). - 2053-4701 .- 2053-4701. ; 5
-
Journal article (peer-reviewed)abstract
- Perceived quality refers to customers’ cognitive and emotional responses to a particular design, often also associated with craftsmanship and customer satisfaction. Previous research defined a taxonomy of perceived quality and provided understanding about how engineering design decisions impact customer satisfaction. Furthermore, development of new products is frequently based on carrying over attributes of existing products, either from the same producer or from competitors. Previous research offered a new product development methodology combining variations of subsystems to carry over from existing products. This brief presents how these two lines of research combined to design the central console of the Porsche Panamera automobile and discusses the opportunities and challenges posed in the practical implementation of this research.

- 2005
-
Doctoral thesis (other academic/artistic)abstract
- Concideration of products' ergonomic qualitys is one important component for successful product developement. Product designers engaged in the core activity of product developement need methods that support the consideration of ergonomics along with other product requirements. this thesis aims to adress these needs. The first part of the thesis investigates how people working within product developement organisations communicate with and about users of their products. The general need for methods to support communication of user aspects in product development is indentified trough formal interviews whith product developers and a review of the management, ergonomics and design litterature. The second part of the thesis studies the factors wich affect th integration of ergonomics in product design. Supportive methods, including User Characters, for evoking user concideration among designers together with Overlapping methods fos scheduling ergonomics evaluation in product design processes are introduced and argued. The third part of the thesis reviews an discusses computer aided ergonomics as a mens for integration of ergonomics in product design. A web-based support system for effective employment of human simulation tools is developed using a participativa approach and evaluated based on the system's usability. The objective of the fourt part of the thesis is to study how human simulation tool can aid designers' consideration of human diversity to accomodate users of diverse anthropometric characteristics in multivariate design problems such as automobile cockpits. The work involves the evaluation off different approaches for th egeneration of specific manikin families wich can be used as test groups for fitting trials in the virtual design process. The research demonstrates enchantments in design methodology knowledge to support integration of ergonomics in design product processes with a focus on anthopometric diversity in vehicledesign.

Forskarstött förändringsarbete i själva verket : Att förbättra arbetssituationen för 15 000 brevbärare
- 2007
-
Doctoral thesis (other academic/artistic)abstract
- Denna avhandling belyser forskarstött förändringsarbete, inom ”Servicenätet Posten”, den division inom Posten Sverige AB som ansvarar för postdistribution till kunderna. Förändringsarbetet har handlat om att förbättra arbetssituationen för 15 000 brevbärare.Den teoretiska grunden utgörs av ett systemtänkande där konceptet ”Människa-Teknik-Organisation” (MTO), används för att granska interventionsprocessen.Det övergripande syftet med denna avhandling är att bidra till kunskapsutveckling-en om forskarstött förändringsarbete utifrån följande delsyften: 1) att illustrera hur ett systemtänkande i förändringsarbete påverkar förståelsen för hur systemkomponenterna Människa, Teknik och Organisation (MTO) interagerar i praktiken, 2) att exemplifiera hur den kunskapen kan omsättas i praktiken genom utveckling och implementering av MTO-anpassade lösningar i samverkan mellan forskare och praktiker, 3) att empiriskt exemplifiera hur former för participation kan bidra till framgångsrikt förändringsarbete genom analys och syntes av process och resultat.Forskningsprojektet har bedrivits med en interaktiv ansats. Den interaktiva ansatsen har gjort det möjligt att belysa samverkan mellan forskare och praktiker på ett verklig-hetsnära och realistiskt sätt under fyra projektfaser fördelade över en femårsperiod.Den inledande projektfasen innebar en diagnostisering av problematiken. Ett antal åtgärdsförslag presenterades av forskargruppen och ledde vidare till ett forskarstött ut-vecklingsarbete under en andra projektfas då ett underlag till olika förbättringsåtgärder arbetades fram. Detta inbegrep utveckling av såväl teknisk som arbetsorganisatorisk ka-raktär för att åstadkomma effektiva och hälsosamma arbetsprocesser för brevbärare inom postutdelningsverksamheten. I en tredje projektfas testades och utvärderades hela åtgärdspaketet genom implementering på ett pilotkontor. I en fjärde och sista projektfas implementerades förbättringsåtgärderna på samtliga 602 postutdelningskontor i landet och forskarna gjorde en utvärdering.Resultaten visar hur man genom att anlägga ett MTO-perspektiv i förändringsarbete ökar möjligheterna att få klarhet i vilka faktorer som påverkar effektiviteten i ett pro-duktionssystem i sin helhet. Den tvärvetenskapliga forskningssatsningen i kombination med samverkan forskare/praktiker visade sig vara en förutsättning för att skapa förståel-se för interaktionen mellan M-T-O-komponenterna. Avhandlingen visar vidare hur olika former för participation i praktiken kan bidra till framgångsrikt förändringsarbete både vad gäller process och resultat. Den utförliga redogörelsen för interventionsprocessen, forskarrollens skiftande karaktär samt hindrande och främjande faktorer för forskarstött förändringsarbete, utgör andra viktiga kunskapsbidrag.

Perceived Quality Evaluation with the Use of Extended Reality
- 2019

In: Proceedings of the International Conference on Engineering Design, ICED. - : Cambridge University Press (CUP). - 2220-4334 .- 2220-4342. ; 1:1, s. 1993-2002
-
Conference paper (peer-reviewed)abstract
- If designers want to communicate quality aspects of the product, there is a need to bring these characteristics into the measurable space of perceived quality (PQ) attributes. To illustrate the solution for designers' dilemma of the “best design choice” in this study we applied the PQ attributes importance ranking (PQAIR) method, with the example of a bread toaster. We choose for evaluation three PQ attributes which can significantly influence visual quality of a product: Gap, Flush and Parallelism. We performed the experiment measuring subjective preferences over the toaster designs of two respondent's groups - “Designers” and “Customers.” We used sequentially: (i) web-survey (still images); (ii) desktop system; and (iii) fully immersive head-mounted display system (Virtual Reality). Consequently, we conducted a post-experiment survey regarding subjective preferences, related to the PQ communication channels that have been implemented during the study. Our results indicate advantages and drawbacks for each PQ communication method that we applied in this experiment and encourage further research in the area of products' perceived quality assessment.

Model based compensation of systematic errors in an inductive gap measurement method
- 2017
-
In: Measurement : Journal of the International Measurement Confederation. - : Elsevier. - 0263-2241 .- 1873-412X. ; 105, s. 17-24
-
Journal article (peer-reviewed)abstract
- This paper presents an improvement to a recently presented inductive gap measurement method, using a model to reduce systematic errors. Gap measurement is important in laser keyhole welding, where the laser beam and the resulting weld seam are very narrow, requiring high precision in alignment and gap preparation. The previously reported method for gap measurement uses one inductive coil on each side of the gap, each measuring distance to the gap and lift off above a plate, to estimate the position, width and alignment of the gap in a square butt joint. The method can detect zero width gap and shows position error less than 0.1 mm, but gap width and alignment measurement suffer from systematic errors. The improvement is based on a model that is designed to describe these systematic errors as functions of the gap dimensions. The model relies on observations of experimental data, and is calibrated to a small set of measurements. Using the model with the initial estimate of the gap dimensions to compensate the coil measurements, an improved estimate of the gap dimensions can be calculated. The errors in the compensated results are within 0.1 mm except for gap width, which still suffers from the effect of combined gap width and misalignment.

Ship security challenges in high-risk areas : manageable or insurmountable?
- 2015
-
In: WMU Journal of Maritime Affairs (JoMA). - : Springer Berlin/Heidelberg. - 1651-436X .- 1654-1642. ; 14:2, s. 201-217
-
Journal article (peer-reviewed)abstract
- Piracy can lead to risks so high that they, according to the International Maritime Organization, are tolerable only if risk reduction is not practicable or is disproportionate to the benefits achieved. Therefore, there is a need for reducing ship security risks in relation to antagonistic threats such as piracy. The aim of this study is to identify challenges for ship operators when developing their ship security management. Furthermore, this study also investigates two central aspects in the analysis: understanding the threat and understanding how a security threat affects the crew and operation of the ship. It is clear from the analysis that the importance of subjective aspects beyond a ship operators’ direct control is high. This seems to be the fact for all aspects of the risk management process. The situation is also dynamic as the security risk, as well as the risk perception, can change dramatically even though there are no actual operational changes. As a result, the ship security management process is highly iterative and depends on situations on board as well as conditions out of the ship operator’s control. In order to make ship security manageable, the risk management has to put particular focus on methodological understanding, relevant system understanding and well-defined risk acceptance criteria as well as on including all levels of the organization in the risk reduction implementation and on a continuous monitoring.

Machine Interpretable Representation of Commander's Intent
- 2008
-
In: Proceedings of the 13th International Command and Control Research and Technology Symposium (13th ICCRTS).
-
Conference paper (peer-reviewed)abstract
- The Network-Centric approach envisioned in the Global Information Grid enables the interconnection of systems in a dynamic and flexible architecture to support multi-lateral, civilian and military missions. Constantly changing environments require commanders to plan for missions that allow organizations from various nations and agencies to join or separate from the teams performing the missions, depending on the situation, as missions unfold. The uncertainty within an actual mission, and the variety of potential organizations that support the mission after it is underway, makes Command Intent (CI) a critical concept for the mission team. With new and innovative information technologies, CI can now be made available to the team of organizations in a coalition environment. Using a flexible and linguistically based approach for representing CI allows Intent to be interpreted and processed by all participants – both humans and machines. CI representations need to be able to express mission team’s purpose, the anticipated End-State of the mission and desired key tasks. In this work, the expression of CI is developed to enable the structure and dynamics of collaboration support.

The Future of Work for Quality Management – Challenges in the Digitalized Era
- 2018
-
Conference paper (other academic/artistic)abstract
- Purpose Digitalization provides both challenges and opportunities for Quality Management (QM). The purpose of this paper is to identify challenges induced by digitalization on current QM practices, in order to uncover the potential of how QM may support digitalization in organizations. This issue is addressed through an analytical framework that stresses two dimensions: first exploration and exploitation of digitalized QM processes and second value creation, which is performed by the customer or in interaction facilitated by the provider. Design/methodology/approach This paper is based on a cross-case study design with interview data collected from 33 quality management professionals in four large Swedish organizations. Findings Six different challenges and corresponding roles are proposed for QM: The gardener involved in the design of the many different currently utilized technologies; the bridge-builder - a role that connects implemented digitalized solutions that enable the movement from human-to-human to a human-to-digital interface; the assistant a contributor to better value in the customer sphere for already implemented digitalized solutions; the architect including planning, designs, and reviews together with many different stakeholders; the connector focusing on the continuous management of value-in-use and open up for opportunities for continuous interaction and value-adding; and explorer drawing attention towards the challenges of the existing power structures. Originality/value This paper contributes with empirical evidence on challenges induced by digitalization, an area often discussed but not as often studied empirically. Further, the study identifies challenges of digitalization affecting both exploitative and explorative practices throughout an organisations value-creation process.

Modelling of cathode-plasma interaction in short high-intensity electric arc : Application to Gas Tungsten Arc Welding
- 2016
-
Doctoral thesis (other academic/artistic)abstract
- In arc welding the quality of the weld is strongly influenced by the thermal history of the workpiece which is itself governed by the electric arc heat source. The models for predicting weld properties thus need a good evaluation of the distribution of the heat input from thearc to the workpiece. To have a predictive model of arc heat source it is necessary to take into account the cathode and its coupling with the plasma. The coupling allows to calculate the temperature and current density distributions along the cathode surface rather than prescribing them. This thesis focuses on the arc-cathode coupling for a plasma assumed to be in local thermal equilibrium. A self-consistent coupling boundary model for high-intensity electric arc on a refractory cathode (thoriated tungsten) was developed accounting for the physics of the sub-layers of the cathode layer and the non-uniformity of the cathode surface physical state. The cathode layer model accounts for the non-equilibria in the cathode layer. It was tested in one-dimensional calculations and then extended to a cathode-plasma coupling boundary condition for gas tungsten arc implemented in OpenFOAM. Different modelling assumptions commonly used for developing the model were questioned and investigated. It was checked that the secondary electron emission is negligible compared to the effect of emitted electrons and ions. It was verified that it is justified to neglect the space charge of emitted electron when calculating the cathode surface electric field. It was verified that Richardson-Dushman electron emission law supplemented with Schottky correction is used within its domain of validity in GTA applications even for low work function emitters. It was shown that the radiative absorption of the cathode surface is not negligible compared to the radiative emission. The cathode layer model was also further developed to take into account the in homogeneity of the cathode material. It was shown that the cathode in homogeneityhas a significant effect on the size of the arc attachment and consequently on the cathode surface and the plasma temperature. Good agreement was obtained with the measured cathode surface and plasma temperatures without imposing any adjustable parameters. The results showed that the proposed model, which is only based on physical principles, is ableto predict the trends observed experimentally.

Journal article (peer-reviewed)abstract
- The geometrical quality of a welded assembly is to some extent depending part positions before welding. Here, a design of experiment is set up in order to investigate this relation using physical tests in a controlled environment. Based on the experimental results it can be concluded that the influence of part position before welding is significant for geometrical deviation after welding. Furthermore, a working procedure for a completely virtual geometry assurance process for welded assemblies is outlined. In this process, part variations, assembly fixture variations and welding induced variations are important inputs when predicting the capability of the final assembly.

Perceived quality of products: a framework and attributes ranking method
- 2020
-
In: Journal of Engineering Design. - : Informa UK Limited. - 1466-1837 .- 0954-4828. ; 31:1, s. 37-67
-
Journal article (peer-reviewed)abstract
- Perceived quality is one of the most critical aspects of product development that defines the successful design. This paper presents a new approach to perceived quality assessment by examining its elements, decomposed into a structure with the bottom-up sensory approach from the level of basic (‘ground’) attributes, covering almost every aspect of quality perception from the engineering viewpoint. The paper proposes a novel method for perceived quality attributes relative importance ranking, resulting in the balanced perceived quality of the final product within the given conditions. The proposed method helps to reach the equilibrium of the product’s quality equation from the perspective of design effort, time, and costs estimations. The authors introduce the Perceived Quality Framework (PQF), which is the taxonomy system for perceived quality attributes and the core of the attributes importance ranking (PQAIR) method. The research outcomes are based on findings of the qualitative exploratory study, including European and North American premium and luxury automotive manufacturers. An empirical structural validity test was performed to assess the usability and rigour of the proposed method. The results indicate that perceived quality evaluation can be significantly improved during all stages of product development.
