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.

Teollisen tuotannon ja palvelun ulkoistaminen Intiaan

Diplomityössä on tarkoituksena kartoittaa asioita, joita pitää ottaa huomioon pk-yrityksen tuotannon ulkoistamisessa Intiaan sekä laskemaan kuinka paljon halvemmaksi kiertovoitelukeskusten valmistaminen Intiassa tulee verrattuna Suomeen. Teoriaosuudessa on tarkasteltu Intian erilaista kulttuuria sekä kartoitettu asioita, jotka vaikuttavat länsimaalaisen yrityksen toimintaan Intiassa sekä mahdollisuuksia eri teollisuuden aloille. Empiriaosuudessa on keskitytty eri vaihtoehdoin kiertovoitelukeskuksen valmistuskustannuksiin ja niiden vertailuun Intian ja Suomen välillä. Tuloksena on voitu todeta, että valmistus Intiassa tulee selvästi halvemmaksi kuin Suomessa. Ensi askelten ottaminen luultavasti tulee olemaan vaikeaa lähinnä asiakkaiden löytämisessä ja verkostojen rakentamisessa. Riskejä oman tuotantolaitoksen perustamisessa Intiaan on, mutta myös mahdollisuudet ja potentiaali menestykselliseen liiketoimintaan ovat suuret. Ulkoistaminen on vain tehtävä maltillisesti ja järkevästi ja tehtyihin päätöksiin täytyy sitoutua.

Reaching influential early adopters effectively in Finland : Rock Science – new generation board game

Innovations diffuse at different speed among the members of a social system through various communication channels. The group of early adopters can be seen as the most influential reference group for majority of people to base their innovation adoption decisions on. Thus, the early adopters can often accelerate the diffusion of innovations. The purpose of this research is to discover means of diffusion for an innovative product in Finnish market through the influential early adopters in respect to the characteristics of the case product. The purpose of the research can be achieved through the following sub objectives:  Who are the potential early adopters for the case product and why?  How the potential early adopters of the case product should be communicated with?  What would be the expectations, preferences, and experiences of the early adopters of the case product? The case product examined in this research is a new board game called Rock Science which is considered to be incremental innovation bringing board gaming and hard rock music together in a new way. The research was conducted in two different parts using both qualitative and quantitative research methods. This mixed method research began with expert interviews of six music industry experts. The information gathered from the interviews enabled researcher to compose the questionnaire for the quantitative part of the study. Internet survey that was sent out resulted with a sample of 97 responses from the targeted population. The key findings of the study suggest that (1) the potential early adopters for the case product are more likely to be young adults from the capital city area with great interest in rock music, (2) the early adopters can be reached effectively through credible online sources of information, and (3) the respondents overall product feedback is highly positive, except in the case of quality-price ratio of the product. This research indicates that more effective diffusion of Rock Science board game in Finland can be reached through (1) strategic alliances with music industry and media partnerships, (2) pricing adjustments, (3) use of supporting game formats, and (4) innovative use of various social media channels.

The board of directors as a part of family business governance – multilevel participation and board development

In this study, I examine the board of directors as a part of family business governance. Both boards and governance have increased their attractiveness as a research topic lately. Research on boards has concentrated mostly on the study of different board attributes, like composition, and the relationship of these attributes to the firm’s performance. Family business governance studies are criticized for ignoring the multifaceted needs of companies. More research observing the context and contingencies affecting the governance and board of directors is needed. The objective of this study is to clarify: 1) how the board participates in family business governance, and 2) how the board develops along with the firm’s and family’s development. The study is implemented as qualitative research, and the longitudinal process approach has been used as it provides the opportunity to examine development in context. Selection criteria for the two cases selected for this study are: active board of directors, at least one implemented succession, and interviewees available from two generations and from different positions in the firm. The data consists of interviews and secondary data, and it is collected from different data sources. The analysis was done selecting first some critical events from both cases to closer examination, and analysing them by using content analysis technique. Several conclusions were drawn basing on the findings. First, the family business board participates in the firm’s activities much more widely than it is customary to think. Second, the family business board is not a static part of the business, but it develops and it has to develop for different reasons. Third, ownership is not only the basis for the board’s activities or existence, but the relationship between the board and ownership is two-way. The board contributes to a large extent to the ownership decisions, and in this way to the management of ownership. Fourth, according to the cases, the board has many unrecognized possibilities to facilitate succession in family firms.

Development of agnostic mobile applications with cross-platform cloud computing platforms

Smart phones became part and parcel of our life, where mobility provides a freedom of not being bounded by time and space. In addition, number of smartphones produced each year is skyrocketing. However, this also created discrepancies or fragmentation among devices and OSes, which in turn made an exceeding hard for developers to deliver hundreds of similar featured applications with various versions for the market consumption. This thesis is an attempt to investigate whether cloud based mobile development platforms can mitigate and eventually eliminate fragmentation challenges. During this research, we have selected and analyzed the most popular cloud based development platforms and tested integrated cloud features. This research showed that cloud based mobile development platforms may able to reduce mobile fragmentation and enable to utilize single codebase to deliver a mobile application for different platforms.

Suorituskyvyn johtaminen ja IT-strategian suuntaaminen; Case: ICT-alan yritys

Yrityksen tietohallintoon kohdistuu tänä päivänä paljon vaatimuksia. Vaatimukset kohdistuvat tietohallinnon merkitykseen liiketoiminnan tukijana ja suorituskyvyn edistäjänä. ICT-toimialan rooli palveluiden tuottajana ja Suomen taloudellisen kas-vun tukijana ovat merkittävät. Tämän diplomityön tavoite on selvittää mikä on tietohallinnon rooli ja merkitys osana yrityksen suorituskykyä ja miten sitä tulisi kehittää. Tutkimuksen teoreettinen viitekehys koostuu yleisistä suorituskyvyn johtamisen malleista, suorituskyvyn joh-tamisen malleista tietohallinnossa sekä IT-strategian suuntaamisen malleista ja suuntaamisen vaikutuksesta yrityksen suorituskykyyn. Tutkimuskysymys on: miten strategian suuntaamista tulisi kehittää jotta tietohallinto pystyisi edistämään yrityk-sen suorituskykyä? Tutkimusstrategia on case-tutkimus ja empiirinen aineisto on hankittu teemahaastatteluilla. Case-tutkimuksen tulosten mukaan strategian suuntaamisen arvioinnin mallin valit-seminen on tärkeää. Strategian suuntaamisen kaikki näkökulmat tulee ottaa huomi-oon. Esimerkiksi osaaminen, kommunikaatio, kumppanuudet ja ihmisten käyttäy-tyminen saattavat jäädä ns. kovien näkökulmien varjoon. Strategian suuntaamisessa tulee kiinnittää huomiota suuntaamiseen kaikilla organisaatiotasoilla. Toiminnalli-sen tason merkitys tulee myös huomioida. Strategian suuntaamista kehitettäessä tulee arvioinnissa ottaa huomioon eri liiketoimintayksiköiden arvioinnit, koska ne saattavat poiketa vahvasti toisistaan ja siten vääristää kehittämiskohteiden valitse-mista.

Palvelun hankinnan prosessi ja laatu. Case: Espoon kaupungin koulukuljetukset

Palvelujen hankinta on yhä kiinteämmin osa yritysten liiketoimintaa, kun kiristyvässä kilpailussa yritykset pyrkivät siirtämään keskittymistään enenevissä määrin ydintoimintojensa tuottamiseen. Yleisiä ohjeistuksia palveluiden laadun kehittämisestä ja hankintaprosessin läpiviennistä on olemassa runsaasti, mutta palveluihin keskittyvän hankinnan kokonaisvaltaista kuvausta on tutkimuskentästä vaikea löytää. Tämän tutkimuksen tavoitteena on tutkia palvelun hankinnan prosessia ja laatua, sekä paikata olemassa olevaa tutkimusaukkoa tunnistaen hankintaprosessista lopputuloksen laadun kannalta kriittisiä elementtejä. Tutkimusaihetta lähestytään tarkastelemalla ensin olemassa olevaa tutkimusta palvelujen hankintaprosessista ja laadusta. Lisäksi tutkimusta varten on haastateltu hankinta-asiantuntijoita, sekä suoritettu case-tutkimus Espoon kaupungin koulukuljetusten hankinnasta, jossa hyödynnetään QFD-matriisianalyysiä kriittisten tekijöiden tunnistamiseksi. Lopputuloksena tutkimus esittää hankintaprosessiin perustuvan listan niistä laadukkaan lopputuloksen kannalta kriittisistä tekijöistä, joihin keskittymällä palveluhankinnan laatua on mahdollista parantaa. Keskeisimpinä tekijöinä tuloksissa esiin nousevat hankintatiimin kokoaminen, yrityksen tahtotilan tunnistaminen, palvelusisällön ja sen tavoitteiden ymmärtäminen, sanktiomallien hyödyntäminen, sekä yhteistyön vaaliminen hankinnan suunnittelussa ja sopimusseurannassa.
