Fuzzy ontology for knowledge mobilisation and decision support

A growing concern for organisations is how they should deal with increasing amounts of collected data. With fierce competition and smaller margins, organisations that are able to fully realize the potential in the data they collect can gain an advantage over the competitors. It is almost impossible to avoid imprecision when processing large amounts of data. Still, many of the available information systems are not capable of handling imprecise data, even though it can offer various advantages. Expert knowledge stored as linguistic expressions is a good example of imprecise but valuable data, i.e. data that is hard to exactly pinpoint to a definitive value. There is an obvious concern among organisations on how this problem should be handled; finding new methods for processing and storing imprecise data are therefore a key issue. Additionally, it is equally important to show that tacit knowledge and imprecise data can be used with success, which encourages organisations to analyse their imprecise data. The objective of the research conducted was therefore to explore how fuzzy ontologies could facilitate the exploitation and mobilisation of tacit knowledge and imprecise data in organisational and operational decision making processes. The thesis introduces both practical and theoretical advances on how fuzzy logic, ontologies (fuzzy ontologies) and OWA operators can be utilized for different decision making problems. It is demonstrated how a fuzzy ontology can model tacit knowledge which was collected from wine connoisseurs. The approach can be generalised and applied also to other practically important problems, such as intrusion detection. Additionally, a fuzzy ontology is applied in a novel consensus model for group decision making. By combining the fuzzy ontology with Semantic Web affiliated techniques novel applications have been designed. These applications show how the mobilisation of knowledge can successfully utilize also imprecise data. An important part of decision making processes is undeniably aggregation, which in combination with a fuzzy ontology provides a promising basis for demonstrating the benefits that one can retrieve from handling imprecise data. The new aggregation operators defined in the thesis often provide new possibilities to handle imprecision and expert opinions. This is demonstrated through both theoretical examples and practical implementations. This thesis shows the benefits of utilizing all the available data one possess, including imprecise data. By combining the concept of fuzzy ontology with the Semantic Web movement, it aspires to show the corporate world and industry the benefits of embracing fuzzy ontologies and imprecision.

Balancing creativity and risk intelligence in professional knowledge-intensive business services

The main strengths of professional knowledge-intensive business services (P-KIBS) are knowledge and creativity which needs to be fostered, maintained and supported. The process of managing P-KIBS companies deals with financial, operational and strategic risks. That is why it is reasonable to apply risk management techniques and frameworks in this context. A significant challenge hides in choosing reasonable ways of implementing risk management, which will not limit creative ability in organization, and furthermore will contribute to the process. This choice is related to a risk intelligent approach which becomes a justified way of finding the required balance. On a theoretical level the field of managing both creativity and risk intelligence as a balanced process remains understudied in particular within KIBS industry. For instance, there appears to be a wide range of separate models for innovation and risk management, but very little discussion in terms of trying to find the right balance between them. This study aims to shed light on the importance of well-managed combination of these concepts. The research purpose of the present study is to find out how the balance between creativity and risk intelligence can be managed in P-KIBS. The methodological approach utilized in the study is strictly conceptual without empirical aspects. The research purpose can be achieved through answering the following research supporting questions: 1. What are the characteristics and role of creativity as a component of innovation process in a P-KIBS company? 2. What are the characteristics and role of risk intelligence as an approach towards risk management process implementation in a P-KIBS company? 3. How can risk intelligence and creativity be balanced in P-KIBS? The main theoretical contribution of the study conceals in a proposed creativity and risk intelligence stage process framework. It is designed as an algorithm that can be applied on organizational canvas. It consists of several distinct stages specified by actors involved, their roles and implications. Additional stage-wise description provides detailed tasks for each of the enterprise levels, while combining strategies into one. The insights driven from the framework can be utilized by a vast range of specialists from strategists to risk managers, and from innovation managers to entrepreneurs. Any business that is designing and delivering knowledge service can potentially gain valuable thoughts and expand conceptual understanding from the present report. Risk intelligence in the current study is a unique way of emphasizing the role of creativity in professional knowledge-intensive industry and a worthy technique for making profound decisions towards risks.

Project Management Tools in Agile Embedded Systems Development

Agile methods have become increasingly popular in the field of software engineering. While agile methods are now generally considered applicable to software projects of many different kinds, they have not been widely adopted in embedded systems development. This is partly due to the natural constraints that are present in embedded systems development (e.g. hardware–software interdependencies) that challenge the utilization of agile values, principles and practices. The research in agile embedded systems development has been very limited, and this thesis tackles an even less researched theme related to it: the suitability of different project management tools in agile embedded systems development. The thesis covers the basic aspects of many different agile tool types from physical tools, such as task boards and cards, to web-based agile tools that offer all-round solutions for application lifecycle management. In addition to these two extremities, there is also a wide range of lighter agile tools that focus on the core agile practices, such as backlog management. Also other non-agile tools, such as bug trackers, can be used to support agile development, for instance, with plug-ins. To investigate the special tool requirements in agile embedded development, the author observed tool related issues and solutions in a case study involving three different companies operating in the field of embedded systems development. All three companies had a distinct situation in the beginning of the case and thus the tool solutions varied from a backlog spreadsheet built from scratch to plug-in development for an already existing agile software tool. Detailed reports are presented of all three tool cases. Based on the knowledge gathered from agile tools and the case study experiences, it is concluded that there are tool related issues in the pilot phase, such as backlog management and user motivation. These can be overcome in various ways epending on the type of a team in question. Finally, five principles are formed to give guidelines for tool selection and usage in agile embedded systems development.

Uuden tiedon hankinta ja hyödyntäminen organisaation innovaatioprosesseissa

Tämän tutkimuksen tavoitteena oli tutkia, miten uuden ja erityisesti tulevaisuuteen suuntautuvan tiedon hankintaa ja hyödyntämistä organisaatioiden innovaatioprosesseissa voidaan tarkastella ja jäsentää sekä kehittää avoimen innovaatioteorioiden pohjalta. Tulevaisuustiedon järjestelmällinen hyödyntäminen on yhä tärkeämmässä asemassa 2010-luvun organisaatioiden innovatiivisuuden ja kilpailukyvyn kannalta. Tämä on abstraktin luonteensa vuoksi erittäin haasteellista mutta teoriassa mahdollista, jos uuden tiedon liittämisestä organisaation käyttöön on tehty tärkeä ja selkeä osa koko organisaation strategiaa. Uuden tiedon tehokkaaseen käsittelemiseen ja siirtämiseen organisaatiossa tarvitaan suunnitelmallista ennakointitoimintaa, sosiaalisia sovittelumekanismeja ja rakentavaa yhteistyötä myös ulkopuolisten toimijoiden kanssa. Valitun teoriakehyksen pohjalta laadittiin yksinkertaistettu kyselytutkimus, johon oli liitetty absorptiiviseen kapasiteettiin, visionääriseen kyvykkyyteen, ennakointitoimintaan ja uuden tiedon käsittelyyn liittyviä käsitteitä. Kyselyn tarkoituksena oli myös tarjota organisaatiolle mahdollisuus tarkastella nykyistä tilaansa uuden tiedon monivaiheisen hyödyntämisen kannalta. Kyselytutkimus lähetettiin suomalaisille teollisuusyrityksille ja saatuja vastauksia käytettiin empiirisenä aineistona. Empiiristä aineistoa tarkasteltiin kvantitatiivisin menetelmän ja tuloksista saatiin hyödyllistä tietoa yritysten toiminnasta käytännöntasolta.

Utilization of steelmaking waste materials for production of calcium carbonate (CaCO3)

The steel industry produces, besides steel, also solid mineral by-products or slags, while it emits large quantities of carbon dioxide (CO2). Slags consist of various silicates and oxides which are formed in chemical reactions between the iron ore and the fluxing agents during the high temperature processing at the steel plant. Currently, these materials are recycled in the ironmaking processes, used as aggregates in construction, or landfilled as waste. The utilization rate of the steel slags can be increased by selectively extracting components from the mineral matrix. As an example, aqueous solutions of ammonium salts such as ammonium acetate, chloride and nitrate extract calcium quite selectively already at ambient temperature and pressure conditions. After the residual solids have been separated from the solution, calcium carbonate can be precipitated by feeding a CO2 flow through the solution. Precipitated calcium carbonate (PCC) is used in different applications as a filler material. Its largest consumer is the papermaking industry, which utilizes PCC because it enhances the optical properties of paper at a relatively low cost. Traditionally, PCC is manufactured from limestone, which is first calcined to calcium oxide, then slaked with water to calcium hydroxide and finally carbonated to PCC. This process emits large amounts of CO2, mainly because of the energy-intensive calcination step. This thesis presents research work on the scale-up of the above-mentioned ammonium salt based calcium extraction and carbonation method, named Slag2PCC. Extending the scope of the earlier studies, it is now shown that the parameters which mainly affect the calcium utilization efficiency are the solid-to-liquid ratio of steel slag and the ammonium salt solvent solution during extraction, the mean diameter of the slag particles, and the slag composition, especially the fractions of total calcium, silicon, vanadium and iron as well as the fraction of free calcium oxide. Regarding extraction kinetics, slag particle size, solid-to-liquid ratio and molar concentration of the solvent solution have the largest effect on the reaction rate. Solvent solution concentrations above 1 mol/L NH4Cl cause leaching of other elements besides calcium. Some of these such as iron and manganese result in solution coloring, which can be disadvantageous for the quality of the PCC product. Based on chemical composition analysis of the produced PCC samples, however, the product quality is mainly similar as in commercial products. Increasing the novelty of the work, other important parameters related to assessment of the PCC quality, such as particle size distribution and crystal morphology are studied as well. As in traditional PCC precipitation process, the ratio of calcium and carbonate ions controls the particle shape; a higher value for [Ca2+]/[CO32-] prefers precipitation of calcite polymorph, while vaterite forms when carbon species are present in excess. The third main polymorph, aragonite, is only formed at elevated temperatures, above 40-50 °C. In general, longer precipitation times cause transformation of vaterite to calcite or aragonite, but also result in particle agglomeration. The chemical equilibrium of ammonium and calcium ions and dissolved ammonia controlling the solution pH affects the particle sizes, too. Initial pH of 12-13 during the carbonation favors nonagglomerated particles with a diameter of 1 μm and smaller, while pH values of 9-10 generate more agglomerates of 10-20 μm. As a part of the research work, these findings are implemented in demonstrationscale experimental process setups. For the first time, the Slag2PCC technology is tested in scale of ~70 liters instead of laboratory scale only. Additionally, design of a setup of several hundreds of liters is discussed. For these purposes various process units such as inclined settlers and filters for solids separation, pumps and stirrers for material transfer and mixing as well as gas feeding equipment are dimensioned and developed. Overall emissions reduction of the current industrial processes and good product quality as the main targets, based on the performed partial life cycle assessment (LCA), it is most beneficial to utilize low concentration ammonium salt solutions for the Slag2PCC process. In this manner the post-treatment of the products does not require extensive use of washing and drying equipment, otherwise increasing the CO2 emissions of the process. The low solvent concentration Slag2PCC process causes negative CO2 emissions; thus, it can be seen as a carbon capture and utilization (CCU) method, which actually reduces the anthropogenic CO2 emissions compared to the alternative of not using the technology. Even if the amount of steel slag is too small for any substantial mitigation of global warming, the process can have both financial and environmental significance for individual steel manufacturers as a means to reduce the amounts of emitted CO2 and landfilled steel slag. Alternatively, it is possible to introduce the carbon dioxide directly into the mixture of steel slag and ammonium salt solution. The process would generate a 60-75% pure calcium carbonate mixture, the remaining 25-40% consisting of the residual steel slag. This calcium-rich material could be re-used in ironmaking as a fluxing agent instead of natural limestone. Even though this process option would require less process equipment compared to the Slag2PCC process, it still needs further studies regarding the practical usefulness of the products. Nevertheless, compared to several other CO2 emission reduction methods studied around the world, the within this thesis developed and studied processes have the advantage of existing markets for the produced materials, thus giving also a financial incentive for applying the technology in practice.

Employees’ continuous learning and job satisfaction - effects on productivity

In today’s knowledge intense economy the human capital is a source for competitive advantage for organizations. Continuous learning and sharing the knowledge within the organization are important to enhance and utilize this human capital in order to maximize the productivity. The new generation with different views and expectations of work is coming to work life giving its own characteristics on learning and sharing. Work should offer satisfaction so that the new generation employees would commit to organizations. At the same time organizations have to be able to focus on productivity to survive in the competitive market. The objective of this thesis is to construct a theory based framework of productivity, continuous learning and job satisfaction and further examine this framework and its applications in a global organization operating in process industry. Suggestions for future actions are presented for this case organization. The research is a qualitative case study and the empiric material was gathered by personal interviews concluding 15 employee and one supervisor interview. Results showed that more face to face interaction is needed between employees for learning because much of the knowledge of the process is tacit and so difficult to share in other ways. Offering these sharing possibilities can also impact positively to job satisfaction because they will increase the sense of community among employees which was found to be lacking. New employees demand more feedback to improve their learning and confidence. According to the literature continuous learning and job satisfaction have a relative strong relationship on productivity. The employee’s job description in the case organization has moved towards knowledge work due to continuous automation and expansion of the production process. This emphasizes the importance of continuous learning and means that productivity can be seen also from quality perspective. The normal productivity output in the case organization is stable and by focusing on the quality of work by improving continuous learning and job satisfaction the upsets in production can be handled and prevented more effectively. Continuous learning increases also the free human capital input and utilization of it and this can breed output increasing innovations that can increase productivity in long term. Also job satisfaction can increase productivity output in the end because employees will work more efficiently, not doing only the minimum tasks required. Satisfied employees are also found participating more in learning activities.

Tapaustutkimus aineettoman pääoman merkityksestä puupolttoaineiden liiketoiminnassa

Tutkimuksessa selvitetään yhden puupolttoaineorganisaation aineettoman pääoman keskeisimmät tekijät ja niiden välinen dynamiikka laadullisilla tutkimusmenetelmillä. Selvityksen teoreettisen taustan muodostaa tietojohtamisen kirjallisuus, jonka perusteella tietopääoman tekijät on jaettu kolmeen ryhmään: inhimillisiin, rakenne- ja suhdetekijöihin. Puupolttoaineiden liiketoiminta perustuu yksinkertaisen raaka-aineen eli puun hankkimiseen ja toimittamiseen voimalaitoksille eri muodoissa. Liiketoiminnan kannattavuus ja yrityksen asema markkinoilla pohjaa pääosin aineettoman pääoman laaja-alaiseen hyödyntämiseen ja kehittämiseen. Tutkimuksen kohteena on suuren metsäteollisuusyrityksen puunhankintaorganisaatio ja sen puupolttoaineiden liiketoimintayksikkö, jonka arvonmuodostusta ja aineettoman pääoman tekijöitä tutkimuksessa analysoidaan. Tutkimustulokset osoittavat, että puupolttoaineiden liiketoiminnan kannattavuus perustuu henkilöstön vahvaan osaamiseen ja organisaation dynaamisiin johtamismalleihin, joilla voidaan vahvistaa aineettomien tekijöiden yhteisvaikutusta. Haasteena puupolttoainetoiminnassa on aineettoman pääoman tekijöiden suhteuttaminen nopeasti kehittyviin operatiivisiin toimintamalleihin sekä valtiollisiin tukimekanismeihin.

Liiketoimintatiedonhallinnan hyödyntämisen esteet päätettäessä palveluista. Case: Kunnalliset pelastustoimen liikelaitokset ja eriytetyt taseyksiköt

Pelastuslaitosten liiketoimintatiedonhallinnalla, tietoperusteisuudella ja tietojohtamisella on tulevaisuudessa merkittävä rooli päätettäessä palveluista. Julkisen pelastustoimen kuntien liikelaitoksina ja eriytettyinä taseyksiköinä toimivien pelastuslaitosten haasteet tulevat olemaan jatkossa tehokkaiden ja vaikuttavien palveluiden strategisessa johtamisessa ja suunnittelussa. Näistä asioista päättäminen on kriittinen vaihe onnistumisen kannalta. Päätöksenteko eri tasoilla tarvitsee tuekseen toiminnasta ja palveluista kanavoitua analysoitua tietoa. Asiakastarpeesta lähtevä vaikuttavuus ja laatu korostuvat. Liiketoimintatiedonhallinta ja tietoperusteisuus haastavat pelastuslaitoksen johtamisjärjestelmän. Johtamisen kyvykkyys ja henkilöstön osaaminen ovat tietoperusteisuuden ja tiedonhallinnan keskiössä. Systemaattisen liiketoimintatiedonhallinnan ja tietoperusteisuuden erottaa perinteisestä virkamiehen tietojen hyväksikäytöstä käsitteen kokonaisvaltaisuus ja järjestelmällisyys kaikessa tiedollisessa toiminnassa. Tämä kattaa tietojärjestelmät, mittarit, prosessit, strategian suunnitelmat, asiakirjat, raportoinnin, kehittämisen ja tutkimuksen. Liiketoimin-tatiedonhallinta ja tietojohtaminen linkittävät kaiken toisiinsa muodostaen keskinäisriippuvaisen yhtenäisen järjestelmän ja kokonaisvaltaisen ymmärryksen. Tutkimukseni on laadullinen tutkimus jossa tiedon keruu ja analysointi on toteutettu toisiaan tukevilla tutkimusotteilla. Metodologia nojaa teorialähtöiseen systemaattiseen analyysiin, jossa on valikoituja osia sisällön analyysistä. Tutkimuksessa on käytetty aineisto- ja menetelmätriangulaatioita. Tutkimuksen aineisto on kerätty teemahaastatteluilla valittujen kohde pelastuslaitosten asiantuntijoilta palveluiden päätös- ja suunnittelutasolta, johtoryhmistä ja joh-tokunnista. Haastatteluja varten tutkija on tutustunut kohdepelastuslaitosten palveluita mää-rittävään tiedolliseen dokumentaatioon kuten palvelutasopäätöksiin ja riskianalyyseihin. Ai-neisto keruun kohteiksi valikoitui pääkaupunkiseudun alueen pelastuslaitokset: Helsingin kaupungin pelastuslaitos sekä Itä-, Keski- ja Länsi-Uudenmaan pelastuslaitokset. Tulosten mukaan pelastuslaitosten keskeiset liiketoimintatiedonhallinnan esteet muodostuvat johtamisen ongelmista, organisaation muutosvastarinnasta ja päätöksenteon tietoperusteen puutteesta. Nämä ilmenevät strategisen johtamisen puutteina, vaikuttavuuden mittaamisen sekä tiedon jalostamisen ongelmina. Keskeistä tiedollista yhdistävää ja linkittävää tekijää ei tunnisteta ja löydetä. Tiedollisessa liiketoimintatiedonhallinnan prosessityössä voisi olla tulos-ten mukaan mahdollisuuksia tämän tyhjiön täyttämiseen. Pelastuslaitoksille jää tulevaisuudessa valinta suunnasta johon ne haluavat edetä tiedonhal-linnan, tietojohtamisen ja tietoperusteisuuden kanssa. Tämä vaikuttaa kehitykseen ja tavoitteeseen keskeisistä palveluiden päätöksentekoa tukevista johtamis- ja tietojärjestelmistä, tietoa kokoavista ja luovista dokumenteista sekä organisaation joustavasta rakenteesta. Tietoprosessiin, tiedon prosessimaiseen johtamiseen ja systemaattiseen tiedonhallintaan meneminen vaikuttaa tutkimuksen tulosten mukaan lupaavalta mahdollisuudelta. Samalla se haastaa pelauslaitokset suureen kulttuuriseen muutokseen ja asettaa uusien vaikuttavuusmittareiden tuottaman tiedon ennakoivan hyväksynnän vaateen strategiselle suunnittelulle. Tämä vaatii pelastuslaitosten johdolta ja henkilöstöltä osaamista, yhteisymmärrystä, muutostarpeiden hyväksyntää sekä asiakkaan asettamista vaikuttavuuden keskiöön.

Integrating Use of Customer Information Throughout Multiple Sales Channels to Create Customer Competence

Customer knowledge management (CKM) practices enable organizations to create customer competence with systematic use of customer information that is integrated throughout the organization. Nonetheless, organizations are not able to fully exploit the vast amount of data available. Previous research on use of customer information is limited especially in a multichannel environment. The aim of this study was to identify the main obstacles for utilizing customer information efficiently across multiple sales channels. The study was conducted as a single case study in order to gain deeper understanding of the research problem. The empirical findings indicate that lack of CKM practices and a common goal are major challenges obstructing effective utilization of customer information. Furthermore, decentralized organizational structure and insufficient analytical skills create obstacles for information sharing and capabilities to process information and create new knowledge. The implications of the study suggest that in order to create customer competence organizations should shift their focus from technology to the organizational factors affecting use of information and implement CKM practices throughout the organization.

Osaamisen johtaminen - käytäntöjä ja kehittämistarpeita henkilöstön näkökulmasta

Tämän pro gradu -tutkimuksen tavoitteena oli tutkia osaamisen johtamisen käytäntöjä ja kehittämistarpeita kohdeorganisaatiossa henkilöstön näkökulmasta. Tutkimuksen tarkoituksena oli selvittää, miten tehtyjä henkilöstötutkimuksia on hyödynnetty kohdeorganisaatiossa ja näkyykö tämä hyödyntäminen käytännön johtamisessa henkilöstön mielestä. Tutkimus suoritettiin laadullisena tapaustutkimuksena ja empiirinen aineisto kerättiin kuudella teemahaastattelulla, jotka analysoitiin sisällönanalyysimenetelmällä. Tutkimuksessa kartoitettiin, millaisia osaamisen johtamisen käytäntöjä kohdeorganisaatiossa on. Tutkimuksen tuloksien perusteella osaamisen johtamisen peruselementit ovat olemassa: säännölliset palaverit koettiin tärkeiksi, mutta koulutuksien ja kehityskeskusteluiden järjestämisessä sekä jälkiseurannassa henkilöstö näki parannettavaa. Myös hiljaisen tiedon siirtäminen ja hyödyntäminen koettiin merkittäväksi tekijäksi organisaation onnistuneen toiminnan ja jatkuvuuden kannalta. Tutkimuksessa todettiin osaamisen johtamisen kehittämisen ja osaamisen kehittämisen menetelmien linkittyvän vahvasti toisiinsa ja tutkimuksen tuloksena esitettiin konkreettisia toimenpide-ehdotuksia osaamisen johtamisen kehittämisestä kohdeorganisaation johdolle. Tutkimuksen mukaan osaamisen johtaminen ja henkilöstöjohtaminen sulautuvat toisiinsa, eikä niitä voida tarkastella erikseen. Johdon ja henkilöstön välisellä vuorovaikutuksella on suuri merkitys onnistuneelle osaamisen johtamiselle. Keskeistä on kytkeä osaamisen johtaminen organisaation käytäntöihin ja varata sen implementointiin riittävästi resursseja.

“Why share in uncertain conditions?” Factors of individual level knowledge sharing in offshoring cases

The objective of this Master’s Thesis was to research factors influencing and enhancing individual level knowledge sharing in offshore projects which often involve uncertainty of the knowledge provider’s own future. The purpose was to understand why individuals are willing to share their knowledge under these kinds of circumstances. In addition the goal was to identify obstacles to interpersonal knowledge sharing in order to understand how to mitigate their influence. The research was conducted as a qualitative multiple case study in a global IT company, and the data was gathered using semi-structured personal theme interviews within two different offshore projects. In order to a gain a wider perspective on the matter, some management representatives were interviewed as well. Data was analysed with the inductive content analysis method. Results of the study indicate that individuals are willing to share their knowledge despite of uncertainty if they are motivated, if they are provided with opportunities to do so, and if they have skills, competence and experience to share their knowledge. A strong knowledge sharing culture in the organization or team also works as a strong incentive for individual level knowledge sharing. The findings suggest that even under uncertain conditions it is possible to encourage people to share their knowledge if uncertainty can be decreased to a bearable level, a robust and personal connection and relationship between the knowledge provider and acquirer can be created and suitable opportunities for knowledge sharing are provided. In addition, based on the results the support and commitment of management and HR in addition to favourable environmental circumstances play an essential role in building a bridge between the knowledge provider and acquirer in order to create a virtual environment and space for knowledge sharing: Ba.
