Työssä tutkittiin voidaanko helpdesk-asiantuntijoille kehitetyn asiantuntijan ja tietojärjestelmän väliseen dialogiin ja puumaiseen ongelmanratkaisulogiikkaan perustuvan tukijärjestelmän käytöllä tehostaa laajakaistaliittymäviankorjausta. Työ selvitti dialogi-työkalun käyttöönoton jälkeisen vuoden seurantajakson aikana helpdeskin ongelmanratkaisuasteen ja liittymäviankorjausprosessin kehitystä sekä arvioi prosessin tehostumisen vaikutusta palvelun laatuun. Seurantajakson aikana helpdeskissä päätettyjen asiakaskontaktien määrä kasvoi merkittävästi, viankorjausprosessin keskimääräinenläpimenoaika lyhentyi ja vikailmoituksen kohdentamistarkkuus oikeaan työjonoon parani. Prosessin tehostumista kuvaavien mittareiden muutos on tilastollisesti erittäin merkitsevä. Dialogi-työkalulla voidaan tehostaa laajakaistaliittymien viankorjausprosessia merkittävästi ja vaikuttaa joiltain osin myös palvelun laatuun.

Harjoitustöiden vertaisarvioinnissa opiskelijat tarkastavat toistensa töitä ja antavat niistä palautteen annettujen ohjeiden mukaan. Yleensä opiskelijoille annetaan tätä tehtävää tukemaan tietty joukko arviointikriteereitä, joiden osalta työtä ainakin on kommentoitava. Vertaisarviointi voi antaa opiskelijoille monipuolisempaa palautetta kuin ilman sitä olisi mahdollista, mahdollisuuden tehtävien vaihtoehtoisiin ratkaisuihin tutustumiseen sekä kokemusta ongelmanratkaisun analyyttisestä ja kriittisestä tarkastelusta. Lisäksi vertaisarviointi voi tukea opettajien työtä helpottamalla riittävän palautteen antamista opiskelijoille ja antamalla jonkinlaista kuvaa opiskelijoiden näkemyksistä tehtävän aihealueeseen liittyen. Tämän työn tavoitteena on selvittää, mitä mainituista vertaisarviointiin liitetyistä hyödyistä voidaan todellisuudessa saavuttaa ohjelmointipainotteisilla kursseilla. Ohjelmointikurssin opiskelijat arvioivat kurssiin kuuluvien harjoitustöiden yhteydessä toistensa ratkaisuja yhteen tehtävistä. Opiskelijoille suunnatulla kyselyllä pyritään kartoittamaan, kuinka hyvin vertaisarvioinnille asetetut tavoitteet toteutuvat. Kokemuksia opettajan näkökulmasta selvitetään haastattelujen avulla. Testauksen toteutuksessa käytetään verkkosovellusta, johon opiskelijat tallentavat omat työnsä, josta he lataavat itselleen määrätyt työt arvioitavaksi, johon he tallentavat arvionsa ja jonka kautta he lopulta saavat palautteen omasta työstään.

Tutkimuksessa tutkitaan mallintamista ja mittaamista osana liiketoimintaproses-sien parantamista, sekä näiden asioiden kuvaamista soveltuvalla työkalulla. Ensin esitetään teoreettinen viitekehys siihen, kuinka prosesseja voidaan mitata ja mal-lintaa. Sitten raportoidaan käytännössä suoritettu kehitystyö, jolle on määritetty lähtö- ja tavoitetila. Työn onnistumista mitataan johtajahaastatteluin ja saatuja tuloksia verrataan teoriaan. Tutkimuksessa yhdistettiin analyyttinen mallinrakennus, tieteellinen ongelman-ratkaisutoiminta sekä konsultointi tarkoituksena saada aikaan kohde organisaati-olle sopiva konstruktio esitettyyn ongelmaan. Johtajahaastattelut analysoitiin ja suoritettiin kvalitatiivinen tarveanalyysi. Haastatteluja täydennettiin muulla kerä-tyllä aineistolla ja analyysin tarkkuutta pyritään kasvattamaan eri lähdeaineistojen ristivertailuilla. Yrityksissä on niin liiketoiminnalle elintärkeitä ydinprosesseja kuin niitä tukevia tukiprosessejakin. Niiden toiminta perustuu ennalta suunniteltuihin ja uudelleen-käytettäviin menetelmiin. Prosessit tulee sopeuttaa yrityksen arkkitehtuuriin ja niitä on jatkuvasti kehitettävä. Kehittäminen voidaan toteuttaa suurilla kertamuu-toksilla, jatkuvalla laadun parantamisella tai niiden yhdistelmänä. Mallintamisella ja mittaamisella on tärkeä tehtävä liiketoimintaprosessien kehit-tämisessä. Niiden avulla voidaan helpottaa erityisesti prosessien suunnittelua luomalla konkreettisia malleja ja mittareita prosesseista. Toteutuksessa käytettiin prototyyppilähestymistapaa ja työn onnistumista arvioivat yhtiön johtajat. Tutki-muksen tuloksia ovat eri tason prosessimallit, joiden luomisessa käytettiin eri mallintamistekniikoita, sekä mittaristot mittaamaan yrityksen tuottavuutta ja te-hokkuutta.

Työn tavoitteena on luoda poikkileikkaus ongelmalähtöiseen pedagogiikkaan ja erityisesti sen käyttömahdollisuuksiin Yrityspeli-kurssin opettamisessa oppimislähtöisen opetustavan tukena. Toisena tavoitteena on kurssin pelisovelluksen dokumentointi käyttökelpoiseksi viiteteokseksi. Lopuksi työssä tutkitaan sovelluksen keskeisten parametrien ja pelistrategioiden vaikutusta kysyntään. Ongelmalähtöistä oppimista on tutkittu lähinnä kirjallisuuteen perustuen ja täydennetty tietämystä haastattelututkimuksella. Sovelluksen rakenne on havainnoitu käyttämällä sovellusta. Sovelluksen kriittisiä ominaisuuksia on saatu selville ajamalla sovellusta tarkoitusta varten valikoidulla numeerisella aineistolla. Ongelmalähtöinen pedagogiikka osoittautui soveltuvin osin hyväksi opetusmenetelmäksi Yrityspeli-kurssilla mallintamisen ja käytännön ongelmanratkaisutaitojen kehittämisessä. Kurssin pelisovellus näyttäisi toimivan luotettavasti, tosin se ei ole rakenteeltaan erityisen joustava. Sovelluksen keskeisistä parametreista hinnan vaikutus kysyntään on huomattavasti markkinointipanosta suurempi. Testien mukaan pelissä on mahdollista pärjätä niin kustannusjohtajan kuin hintadifferoijankin strategialla.

Case-based reasoning (CBR) is a recent approach to problem solving and learning that has got a lot of attention over the last years. In this work, the CBR methodology is used to reduce the time and amount of resources spent on carry out experiments to determine the viscosity of the new slurry. The aim of this work is: to develop a CBR system to support the decision making process about the type of slurries behavior, to collect a sufficient volume of qualitative data for case base, and to calculate the viscosity of the Newtonian slurries. Firstly in this paper, the literature review about the types of fluid flow, Newtonian and non-Newtonian slurries is presented. Some physical properties of the suspensions are also considered. The second part of the literature review provides an overview of the case-based reasoning field. Different models and stages of CBR cycles, benefits and disadvantages of this methodology are considered subsequently. Brief review of the CBS tools is also given in this work. Finally, some results of work and opportunities for system modernization are presented. To develop a decision support system for slurry viscosity determination, software application MS Office Excel was used. Designed system consists of three parts: workspace, the case base, and section for calculating the viscosity of Newtonian slurries. First and second sections are supposed to work with Newtonian and Bingham fluids. In the last section, apparent viscosity can be calculated for Newtonian slurries.

The purpose of this research is to draw up a clear construction of an anticipatory communicative decision-making process and a successful implementation of a Bayesian application that can be used as an anticipatory communicative decision-making support system. This study is a decision-oriented and constructive research project, and it includes examples of simulated situations. As a basis for further methodological discussion about different approaches to management research, in this research, a decision-oriented approach is used, which is based on mathematics and logic, and it is intended to develop problem solving methods. The approach is theoretical and characteristic of normative management science research. Also, the approach of this study is constructive. An essential part of the constructive approach is to tie the problem to its solution with theoretical knowledge. Firstly, the basic definitions and behaviours of an anticipatory management and managerial communication are provided. These descriptions include discussions of the research environment and formed management processes. These issues define and explain the background to further research. Secondly, it is processed to managerial communication and anticipatory decision-making based on preparation, problem solution, and solution search, which are also related to risk management analysis. After that, a solution to the decision-making support application is formed, using four different Bayesian methods, as follows: the Bayesian network, the influence diagram, the qualitative probabilistic network, and the time critical dynamic network. The purpose of the discussion is not to discuss different theories but to explain the theories which are being implemented. Finally, an application of Bayesian networks to the research problem is presented. The usefulness of the prepared model in examining a problem and the represented results of research is shown. The theoretical contribution includes definitions and a model of anticipatory decision-making. The main theoretical contribution of this study has been to develop a process for anticipatory decision-making that includes management with communication, problem-solving, and the improvement of knowledge. The practical contribution includes a Bayesian Decision Support Model, which is based on Bayesian influenced diagrams. The main contributions of this research are two developed processes, one for anticipatory decision-making, and the other to produce a model of a Bayesian network for anticipatory decision-making. In summary, this research contributes to decision-making support by being one of the few publicly available academic descriptions of the anticipatory decision support system, by representing a Bayesian model that is grounded on firm theoretical discussion, by publishing algorithms suitable for decision-making support, and by defining the idea of anticipatory decision-making for a parallel version. Finally, according to the results of research, an analysis of anticipatory management for planned decision-making is presented, which is based on observation of environment, analysis of weak signals, and alternatives to creative problem solving and communication.

Communication, the flow of ideas and information between individuals in a social context, is the heart of educational experience. Constructivism and constructivist theories form the foundation for the collaborative learning processes of creating and sharing meaning in online educational contexts. The Learning and Collaboration in Technology-enhanced Contexts (LeCoTec) course comprised of 66 participants drawn from four European universities (Oulu, Turku, Ghent and Ramon Llull). These participants were split into 15 groups with the express aim of learning about computer-supported collaborative learning (CSCL). The Community of Inquiry model (social, cognitive and teaching presences) provided the content and tools for learning and researching the collaborative interactions in this environment. The sampled comments from the collaborative phase were collected and analyzed at chain-level and group-level, with the aim of identifying the various message types that sustained high learning outcomes. Furthermore, the Social Network Analysis helped to view the density of whole group interactions, as well as the popular and active members within the highly collaborating groups. It was observed that long chains occur in groups having high quality outcomes. These chains were also characterized by Social, Interactivity, Administrative and Content comment-types. In addition, high outcomes were realized from the high interactive cases and high-density groups. In low interactive groups, commenting patterned around the one or two central group members. In conclusion, future online environments should support high-order learning and develop greater metacognition and self-regulation. Moreover, such an environment, with a wide variety of problem solving tools, would enhance interactivity.
