Engineering Feelings of Quality
- 2008
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There is an increasing emphasis on developing systematical research approaches for design of products that appeal to people’s emotions and values. This thesis proposes methodological developments for investigating people’s subjective emotional needs and values towards quality and explores interactions of related physical design attributes for product design.The overall aim of the licentiate thesis is to gain an understanding on Affective engineering of products through exploring the concept of quality feeling and to develop methodological approaches for this. Quality feeling can be described as a holistic concept considering individuals’ perceptions, expectations, experiences, physical and psychological expressions for a product or service. Affective Engineering methodology aims at translating human psychological processes, such as feelings and emotions, into appropriate product design attributes, such as size, shape, and surface characteristics.The thesis presents three methodological approaches when evaluating products for affective engineering and one approach for an interactive product design support system development.The first study presented deals with feelings of quality for reach truck operator’s cabin components. Components that would convey to give a higher total quality feeling were identified and improvement opportunities were prioritized. The second study presented is based on developing an interactive affective design and decision support system software for design of the steering wheel from drivers’ individual and shared preferences. In the third study affective values arising from judgments for important feelings of quality is the study basis. The author presents research on identifying interactions of design attributes for affective values in waiting areas of primary health care services.Further, a new approach for applying Affective Engineering in design of complex contexts is proposed.The proposed approach aims to handle contexts where feelings and design attributes have complex interactions for products and services that give almost an infinite number of design alternatives that are difficult to handle in traditional Kansei Engineering studies. With this thesis also an interactive product design and decision support system software is developed for steering wheel design and proposed for educational and industrial use. The proposed system works based on linking product design attributes to human feelings by applying Genetic algorithms and provides potential basis for future product development and improvements.This thesis has also contributed with affective design recommendations applicable for vehicle cabins and waiting areas in primary health care. Moreover, a number of existing methods in Affective Engineering have been tested and methodological experience is drawn, including advantages, disadvantages and limitations of using these methods.

A model for simulation and generation of surrounding vehicles in driving simulators
- 2005
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Driving simulators are used to conduct experiments on for example driver behavior, road design, and vehicle characteristics. The results of the experiments often depend on the traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. It is clear that the ability to use phones when driving depends on traffic intensity and composition, and that realistic experiments in driving simulators therefore has to include surrounding traffic.This thesis describes a model that generates and simulates surrounding vehicles for a driving simulator. The proposed model generates a traffic stream, corresponding to a given target flow and simulates realistic interactions between vehicles. The model is built on established techniques for time-driven microscopic simulation of traffic and uses an approach of only simulating the closest neighborhood of the driving simulator vehicle. In our model this closest neighborhood is divided into one inner region and two outer regions. Vehicles in the inner region are simulated according to advanced behavioral models while vehicles in the outer regions are updated according to a less time-consuming model. The presented work includes a new framework for generating and simulating vehicles within a moving area. It also includes the development of enhanced models for car-following and overtaking and a simple mesoscopic traffic model.The developed model has been integrated and tested within the VTI Driving simulator III. A driving simulator experiment has been performed in order to check if the participants observe the behavior of the simulated vehicles as realistic or not. The results were promising but they also indicated that enhancements could be made. The model has also been validated on the number of vehicles that catches up with the driving simulator vehicle and vice versa. The agreement is good for active and passive catch-ups on rural roads and for passive catch-ups on freeways, but less good for active catch-ups on freeways.

Hur kulturen påverkar Svensk-Franska affärsrelationer : En studie av gemensamma industriella projekt mellan SAAB Aerospace i Linköping och Dassault Aviation i Paris
- 2013
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Globaliseringen av affärsrelationer har lett till att individer och företag med olika kulturell bakgrund möts i en mycket större utsträckning än vad som skedde för några decennier sedan. Svenska och franska företag dras med i den globala strömmen: de gemensamma affärsrelationerna, bilaterala projekten och mötena blir alltmer omfattande och intensivare, vilket också innebär att de kulturella skillnaderna mellan nationaliteterna blir kännbara, och de orsakar både problem och möjligheter.Det aktuella forskningsprojektet syftar till att utreda vad som kännetecknar den svenska respektive den franska affärskulturen, samt att studera vilka skillnader i dessa kulturer som påverkar gemensamma samarbetsprocesser. Studien baseras på flera fall av industriella projekt mellan SAAB Aerospace i Linköping och Dassault Aviation i Paris, där flygingenjörer utvecklar högteknologiska produkter.Två olika världar. Studien visar att svenskar respektive fransmän utvecklas i två olika världar. Även om de studerade företagen och deras ingenjörer delar samma tekniska kultur, driver de sina projekt på olika sätt, och skillnaderna kommer till uttryck ofta i samband med gemensamma beslutsprocesser, med tids- och energislukande missförstånd som följd. Besluten tas på olika nivåer, på olika sätt, vid olika tidpunkter och har olika betydelse och bindningskraft om man är i Sverige eller i Frankrike.Olikheter betyder också möjligheter. Man skall dock inte alltid betrakta dessa skillnader som ett problem. En ökad förståelse för varandras mentalitet kan leda dels till att krockar undviks, och att man kan dra fördel av skillnaderna på ett konstruktivt sätt. Den aktuella studien visar att den franska retoriska seden är väl anpassad för att hantera abstrakta frågor samt för att främja innovation. De mer konsensuella svenskarna i sin tur är svårslagna när det gäller medarbetares involvering, samt för att förverkliga idéer och visioner. Olikheter mellan den franska respektive den svenska kulturen kan då komplettera varandra och leda till synergier som kan gagna båda parterna, för ett framgångsrikt samarbete bortom våra gränser.

Collaborative development of resource efficient district heating in Sweden
- 2013
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- An increased recovery of excess heat from industrial processes and thermal power generation could significantly reduce energy demands. Industrial excess heat-based district heating systems are generally considered resource efficient because they reduce the use of fossil fuels and the emissions of greenhouse gases. In addition, collaborating actors can gain financial benefits.In Sweden, although collaboration around heat supply has increased recently, the amount of excess heat that is utilized is low compared to the amount created by industrial processes. Using excess-heat recovery in district heating grids is currently one of the most cost-effective ways of providing additional heat to district heating systems.Expansion and new construction of district heating systems in new residential areas can be seen as an opportunity to further use industrial excess heat. Sweden’s local authorities can influence the development of energy systems used for new residential developments. Increased knowledge about how collaborations evolve could be used to develop strategies that could encourage the development of excess heat-based systems for district heating.This licentiate thesis examines the role of organisational collaboration when it comes to the emergence of resource efficient district heating. The thesis summarises results from three articles and investigates the preconditions for, drivers behind, and barriers to the development of excess heat-based systems for district heating in Sweden. These investigations focus on both the district heating companies’ and industries’ points of view. The thesis also discusses how Swedish spatial planning practice could improve the conditions for resource efficient district heating.Important preconditions for excess-heat collaborations to develop, from the actors’ points of view, are mainly financial. However, relationships based on trust, honesty, shared goals, information transfer, and joint problem solving are also necessary for such collaborations to evolve and develop into long-term successful excess-heat collaborations. These features are also important when it comes to the decision-making process, because knowledge gained through the participation of stakeholders is required to understand common goals and objectives and to put these into practice.As for the development of new excess heat-based district heating systems, results show that the district heating companies generally participate late in the spatial planning process. An earlier dialogue between local authority planners and district heating companies could facilitate the emergence and development of new excess heat-based district heating systems. Furthermore, to facilitate the use of excess heat-based systems, planning should also take into account any nearby industry that produces excess heat. In addition, investment subsidies could encourage the development of excess heat-based systems for district heating and provide long-term environmental benefits for collaborating actors as well as for society at large.

Decision-making in the Requirements Engineering Process : A Human-centred Approach
- 2005
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Complex decision-making is a prominent aspect of requirements engineering and the need for improved decision support for requirements engineers has been identified by a number of authors. A first step toward better decision support in requirements engineering is to understand decision-makers’ complex decision situations. To gain a holistic perspective of the decision situation from a decision-makers perspective, a decision situation framework has been created. The framework evolved through a literature analysis of decision support systems and decision-making theories. The decision situation of requirements engineers has been studied at Ericsson Microwave Systems and is described in this thesis. Aspects of decision situations are decision matters, decision-making activities, and decision processes. Another aspect of decision situations is the factors that affect the decision-maker. A number of interrelated factors have been identified. Each factor consists of problems and these are related to decision-making theories. The consequences of this for requirements engineering decision support, represented as a list that consists of desirable high-level characteristics, are also discussed.

Extending the Service Innovation Concept : Realization and Productivity
- 2013
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this study is to contribute to a better understanding of service innovation by exploring realization as a part of service innovation. Service innovation can be described as something that creates value for customers through new service offerings or service processes while realization refers to the actual use or deployment of the service.My research approach is based on a multiple case study, that focuses on three international firms with origins in Sweden. Empirical material has been gathered through interviews and focus groups. A literature review that tracks the evolution of service innovation further contributes to the exploration of the service innovation concept.Innovation has traditionally been connected to new technology and new products. However the present study has found that service innovation has evolved into a multifaceted concept. Specifically, service innovation is not restricted to the development of new products and services in the shape of new offerings, it also becomes relevant to consider the actual usage of the service offerings. In order to fully understand the process of service innovation, it is important to include the usage of a service offering in the service innovation concept. This realization occurs when the service offering is introduced and used in the customer’s processes, and typically involves both the customer and the provider.This research illustrates how realization requires resources from both the provider and the customer. In general, the realization part of the service innovation process requires more participation from the customer than the development of new offerings. However, this can vary depending on the customer’s competence, intention to interact and level of commitment. Considering an active or recipient customer role and also whether the service offering is directed at the products or the customer processes, this study shows how these different service offerings will have different impacts on service innovation realization, for example, in terms of different resources being required.The extended view of the service innovation concept, includes realization, and is therefore not limited to developing new offerings. This view implies that new areas of innovation that do not necessary need to include new technology, but contribute in other ways to customer value creation must be propelled into focus. Productivity improvements in customer processes are becoming important since they help create customer value (reduced costs, improved quality, reduced down-time etc.). Empirical evidence shows how service offerings that emphasize improvements in customer processes have become more important. This thesis discusses how this view of productivity can result in important benefits for customers, as consideration is given to both customer satisfaction and the use of customer resources. In this respect, productivity becomes a part of the extended service innovation concept.Extending the service innovation concept by adding realization implies an increased emphasis on deployment, and implicitly on customer value creation. Thus, service innovation becomes critical for gaining long-term sustainable competitive advantages through service.

Towards an Ontology Design Pattern Quality Model
- 2013
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The use of semantic technologies and Semantic Web ontologies in particular have enabled many recent developments in information integration, search engines, and reasoning over formalised knowledge. Ontology Design Patterns have been proposed to be useful in simplifying the development of Semantic Web ontologies by codifying and reusing modelling best practices.This thesis investigates the quality of Ontology Design Patterns. The main contribution of the thesis is a theoretically grounded and partially empirically evaluated quality model for such patterns including a set of quality characteristics, indicators, measurement methods and recommendations. The quality model is based on established theory on information system quality, conceptual model quality, and ontology evaluation. It has been tested in a case study setting and in two experiments.The main findings of this thesis are that the quality of Ontology Design Patterns can be identified, formalised and measured, and furthermore, that these qualities interact in such a way that ontology engineers using patterns need to make tradeoffs regarding which qualities they wish to prioritise. The developed model may aid them in making these choices.This work has been supported by Jönköing University.

Deadlock Free Routing in Mesh Networks on Chip with Regions
- 2009
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There is a seemingly endless miniaturization of electronic components, which has enabled designers to build sophisticated computing structureson silicon chips. Consequently, electronic systems are continuously improving with new and more advanced functionalities. Design complexity ofthese Systems on Chip (SoC) is reduced by the use of pre-designed cores. However, several problems related to the interconnection of coresremain. Network on Chip (NoC) is a new SoC design paradigm, which targets the interconnect problems using classical network concepts. Still,SoC cores show large variance in size and functionality, whereas several NoC benefits relate to regularity and homogeneity. This thesis studies some network aspects which are characteristic to NoC systems. One is the issue of area wastage in NoC due to cores of varioussizes. We elaborate on using oversized regions in regular mesh NoC and identify several new design possibilities. Adverse effects of regions oncommunication are outlined and evaluated by simulation. Deadlock freedom is an important region issue, since it affects both the usability and performance of routing algorithms. The concept of faultyblocks, used in deadlock free fault-tolerant routing algorithms has similarities with rectangular regions. We have improved and adopted one suchalgorithm to provide deadlock free routing in NoC with regions. This work also offers a methodology for designing topology agnostic, deadlockfree, highly adaptive application specific routing algorithms. The methodology exploits information about communication among tasks of anapplication. This is used in the analysis of deadlock freedom, such that fewer deadlock preventing routing restrictions are required. A comparative study of the two proposed routing algorithms shows that the application specific algorithm gives significantly higher performance.But, the fault-tolerant algorithm may be preferred for systems requiring support for general communication. Several extensions to our work areproposed, for example in areas such as core mapping and efficient routing algorithms. The region concept can be extended for supporting reuse ofa pre-designed NoC as a component in a larger hierarchical NoC.

Towards an Approach for Efficiency Evaluation of Enterprise Modeling Methods
- 2013
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Nowadays, there is a belief that organizations should keep improving different aspects of theirenterprise to remain competitive in their business segment. For this purpose, it is required to understand the current state of the enterprise, analyze and evaluate it to be able to figure out suitable change measures. To perform such a process in a systematic and structured way, receiving support from powerful tools is inevitable. Enterprise Modeling is a field that can support improvement processes by developing models to show different aspects of an enterprise. An Enterprise Modeling Method is an important support for the Enterprise Modeling. A method is comprised of different conceptual parts: Perspective, Framework,Method Component (which itself contains Procedure, Notation and Concepts), and Cooperation Principles. In an ideal modeling process, both the process and the results are of high quality. One dimension of quality which is in focus in this thesis is efficiency. The issue of efficiency evaluation in Enterprise Modeling still seems to be a rather unexploited research area.The thesis investigates three aspects of Enterprise Modeling Methods: what is the meaning of efficiency in this context, how can efficiency be evaluated and in what phases of a modeling process could efficiency be evaluated. The contribution of the thesis is an approach for evaluation of efficiency in Enterprise Modeling Methods based also on several case studies. The evaluation approach is constituted by efficiency criteria that should be met by (different parts of) a method. While a subset of these criteria always need to be fulfilled in a congruent way, fulfillment of the rest of the criteria depends on the application case. To help the user in initial evaluation of a method, a structure of driving questions is presented.
