Are Evaluation of ICTs Investment Using Decision Support Systems:Case Applications from Distributor's and End User's Perspective Group Decision

The evaluation of investments in advanced technology is one of the most important decision making tasks. The importance is even more pronounced considering the huge budget concerning the strategic, economic and analytic justification in order to shorten design and development time. Choosing the most appropriate technology requires an accurate and reliable system that can lead the decision makers to obtain such a complicated task. Currently, several Information and Communication Technologies (ICTs) manufacturers that design global products are seeking local firms to act as their sales and services representatives (called distributors) to the end user. At the same time, the end user or customer is also searching for the best possible deal for their investment in ICT's projects. Therefore, the objective of this research is to present a holistic decision support system to assist the decision maker in Small and Medium Enterprises (SMEs) - working either as individual decision makers or in a group - in the evaluation of the investment to become an ICT's distributor or an ICT's end user. The model is composed of the Delphi/MAH (Maximising Agreement Heuristic) Analysis, a well-known quantitative method in Group Support System (GSS), which is applied to gather the average ranking data from amongst Decision Makers (DMs). After that the Analytic Network Process (ANP) analysis is brought in to analyse holistically: it performs quantitative and qualitative analysis simultaneously. The illustrative data are obtained from industrial entrepreneurs by using the Group Support System (GSS) laboratory facilities at Lappeenranta University of Technology, Finland and in Thailand. The result of the research, which is currently implemented in Thailand, can provide benefits to the industry in the evaluation of becoming an ICT's distributor or an ICT's end user, particularly in the assessment of the Enterprise Resource Planning (ERP) programme. After the model is put to test with an in-depth collaboration with industrial entrepreneurs in Finland and Thailand, the sensitivity analysis is also performed to validate the robustness of the model. The contribution of this research is in developing a new approach and the Delphi/MAH software to obtain an analysis of the value of becoming an ERP distributor or end user that is flexible and applicable to entrepreneurs, who are looking for the most appropriate investment to become an ERP distributor or end user. The main advantage of this research over others is that the model can deliver the value of becoming an ERP distributor or end user in a single number which makes it easier for DMs to choose the most appropriate ERP vendor. The associated advantage is that the model can include qualitative data as well as quantitative data, as the results from using quantitative data alone can be misleading and inadequate. There is a need to utilise quantitative and qualitative analysis together, as can be seen from the case studies.

Reaalioptioteorian sovellettavuus tuotekehitysinvestointeihin liittyvässä päätöksenteossa.

Tutkielman tavoitteena oli tutkia ja analysoida kirjallisuuden pohjalta reaalioptioteoriaa ja sen käyttömahdollisuuksia reaali-investointien arvioinnisa yleensä ja erityisesti aineettomien investointien ryhmään kuuluvaan tutkimus- ja tuotekehitysinvestointeihin liittyvässä päätöksenteossa. Näkökulmana oli, että tuotekehityshankkeet nähdään investointeina. Tutkielma toteutettiin teoreettisena kirjallisuustutkimuksna ja tutkimusmetodologia oli lähinnä käsiteanalyyttinen. Lähdeaineistona käytettiin pääasiassa ulkomaisten tieteellisten aikakausjulkaisujen artikkeleita sekä investointi- ja rahoitusalan oppikirjoja. Reaalioptioteorian mahdollisuudet reaali-investointien, ja erityisesti tuotekehityshankkeiden, arviointiin näyttävät hyvin lupaavilta monien alan tutkijoiden mukaan. Esille nousi kuitenkin erilaisia ongelmia sovellettaessa teoriaa käytännön tilanteisiin. Teorian ja käytännön tuleekin vielä lähestyä toisiaan.

Tavaratalokaupan strategiset menestystekijät

Improving the Potentials of Logistics Processes: Identification and Solutions

The importance of logistics for companies is a well known and justified issue. Today, enterprises are developing their logistics processes in order to match their products and services to the requirements of the most important customers. Therefore there is a need for developing analysing tools for logistics and especially for analysing the significance of various customer service elements. The aim of this paper is to propose analytic tools for supporting strategic level logistics decision making by emphasizing service level elements on two levels: (1) to introduce and propose approaches to categorize the developing efforts of logistics and (2) to introduce and/or propose approaches for solving some customer service related strategic level logistics problems. This study consists of two parts. In the first part an overview of the work is presented, and the second part comprises eight research papers on the topic of the study. The overview includes an introduction, where strategic and tactical level logistics problems are discussed and the relation of logistics to marketing and customer service issues is presented. In the first part of the study the objectives, the structure, the research strategy and the contribution of the research are described, and the challenges for future research are discussed. In the second part the three first papers deal with the identification of objectives for logistics while the remaining five papaers concentrate on solving customer service related strategic level logistics problems.

Teaching the measurement of blood pressure for both nursing and public health nursing students The purpose of this two-phase study was to develop the teaching of blood pressure measurement within the nursing degree programmes of the Universities of Applied Sciences. The first survey phase described what and how blood pressure measurement was taught within nursing degree programmes. The second intervention phase (2004-2005) evaluated first academic year nursing and public health nursing students’ knowledge and skills results for blood pressure measurement. Additionally, the effect on the Taitoviikko experimental group students’ blood pressure measurement knowledge and skills level. A further objective was to construct models for an instrument (RRmittTest) to evaluate nursing students measurement of blood pressure (2003-2009). The research data for the survey phase were collected from teachers (total sampling, N=107, response rate 77%) using a specially developed RRmittopetus-questionnaire. Quasi-experimental study data on the RRmittTest-instrument was collected from students (purposive sampling, experimental group, n=29, control group, n=44). The RRmittTest consisted of a test of knowledge (Tietotesti) and simulation-based test (TaitoSimkäsi and Taitovideo) of skills. Measurements were made immediately after the teaching and in clinical practice. Statistical methods were used to analyse the results and responses to open-ended questions were organised and classified. Due to the small amount of materials involved and the results of distribution tests of the variables, non-parametric analytic methods were mainly used. Experimental group and control group similar knowledge and skills teaching was based on the results of the national survey phase (RRmittopetus) questionnaire results. Experimental group teaching includes the supervised Taitoviikko teaching method. During Taitoviikko students studied blood pressure measurement at the municipal hospital in a real nursing environment, guided by a teacher and a clinical nursing professional. In order to evaluate both learning and teaching the processes and components of blood pressure measurement were clearly defined as follows: the reliability of measurement instruments, activities preceding blood pressure measurement, technical execution of the measurement, recording, lifestyle guidance and measurement at home (self-monitoring). According to the survey study, blood pressure measurement is most often taught at Universities of Applied Sciences, separately, as knowledge (teaching of theory, 2 hours) and skills (classroom practice, 4 hours). The teaching was implemented largely in a classroom and was based mainly on a textbook. In the intervention phase the students had good knowledge of blood pressure measurement. However, their blood pressure measurement skills were deficient and the control group students, in particular, were highly deficient. Following in clinical practice the experimental group and control group students’ blood pressure measurement recording knowledge improve and experimental groups declined lifestyle guidance. Skills did not improve within any of the components analysed. The control groups` skills on the whole, declined statistically.There was a significant decline amongst the experimental group although only in one component measured. The results describe the learning results for first academic year students and no parallel conclusions should be drawn when considering any learning results for graduating students. The results support the use and further development of the Taitoviiko teaching method. The RRmittTest developed for the study should be assessed and the results seen from a negative perspective. This evaluation tool needs to be developed and retested.

Defining the location factors of new manufacturing site in chemical industry

The objective of this thesis is to examine the factors that have an impact on the location decision of new manufacturing site and to create the relative order of importance of these factors by analytic hierarchy process (AHP). The decision making process especially related to the location selection and the measurement of the location factors are also examined. In theoretical part the character of decision making process and the relevant methods are introduced. Based on the previous studies of other researchers, the location factors are examined and the main research method, analytic hierarchy process, is also introduced. The empirical part of the study mainly follows the phases of decision making process and is emphasized on the main stages of analytic hierarchy process; building the hierarchy, defining the priorities and analyzing the results. The hierarchy is constructed from seven main criteria which all have several sub criteria. The evaluation of the hierarchy is implemented at the group decision making –laboratory and there can be seen significant differences between the importance of criteria. The final stage in the study is to create the appropriate measurement scales to the chosen criteria.

Utilization of a Time Domain Simulator in the Technical and Economic Analysis of a Wind Turbine Electric Drive Train

The amount of installed wind power has been growing exponentially during the past ten years. As wind turbines have become a significant source of electrical energy, the interactions between the turbines and the electric power network need to be studied more thoroughly than before. Especially, the behavior of the turbines in fault situations is of prime importance; simply disconnecting all wind turbines from the network during a voltage drop is no longer acceptable, since this would contribute to a total network collapse. These requirements have been a contributor to the increased role of simulations in the study and design of the electric drive train of a wind turbine. When planning a wind power investment, the selection of the site and the turbine are crucial for the economic feasibility of the installation. Economic feasibility, on the other hand, is the factor that determines whether or not investment in wind power will continue, contributing to green electricity production and reduction of emissions. In the selection of the installation site and the turbine (siting and site matching), the properties of the electric drive train of the planned turbine have so far been generally not been taken into account. Additionally, although the loss minimization of some of the individual components of the drive train has been studied, the drive train as a whole has received less attention. Furthermore, as a wind turbine will typically operate at a power level lower than the nominal most of the time, efficiency analysis in the nominal operating point is not sufficient. This doctoral dissertation attempts to combine the two aforementioned areas of interest by studying the applicability of time domain simulations in the analysis of the economicfeasibility of a wind turbine. The utilization of a general-purpose time domain simulator, otherwise applied to the study of network interactions and control systems, in the economic analysis of the wind energy conversion system is studied. The main benefits of the simulation-based method over traditional methods based on analytic calculation of losses include the ability to reuse and recombine existing models, the ability to analyze interactions between the components and subsystems in the electric drive train (something which is impossible when considering different subsystems as independent blocks, as is commonly done in theanalytical calculation of efficiencies), the ability to analyze in a rather straightforward manner the effect of selections other than physical components, for example control algorithms, and the ability to verify assumptions of the effects of a particular design change on the efficiency of the whole system. Based on the work, it can be concluded that differences between two configurations can be seen in the economic performance with only minor modifications to the simulation models used in the network interaction and control method study. This eliminates the need ofdeveloping analytic expressions for losses and enables the study of the system as a whole instead of modeling it as series connection of independent blocks with no lossinterdependencies. Three example cases (site matching, component selection, control principle selection) are provided to illustrate the usage of the approach and analyze its performance.

Modulointia ohjaavien tekijöiden valinta asiakkaiden, tuotekehityksen ja valmistuksen vaatimusten perusteella

Modular drivers cover the entire product life cycle and when the most important modular drivers are known, it is possible to focus on the most essential areas in modularization. Modular drivers are helpful while planning modularization, selecting modules to manufacture and evaluating the success of the modularization. When the modules are formed based on the modular drivers it is also possible to develop production processes according to the requirements of a certain module. The objective of the Master’s Thesis was to organize the modular drivers based on the weightings in order to make the modularization process easier. The phases to find the most important module drivers were formed based on the existing literature and background material from the company. During the Master’s Thesis project the weights of the modular drivers were determined according to the requirements of customers, product development and manufacturing. The requirements were established by a questionnaire and the weights for the requirements were selected in an interview using the Analytic Hierarchy Process. The modular drivers were compared pairwise by the view point of the requirements of certain group. When the results of the three groups were integrated, the weights of the modular drivers were found and it was possible to select the most important drivers.

Ja vet int va de heter på svenska : interaktion mellan tvåspråkiga elever och deras lärare i en enspråkig klassrumsdiskurs

This is a study about language and learning aspects in the interaction between pupils and teachers in classrooms, where the majority of the pupils are bilingual. The aim of the dissertation is to develop the understanding of interactional learning possibilities and constraints in relation to a bilingual context. Language related learning is used as an overall conception which covers learning related to classroom discourse, language and subject. The empirical study has been made in a Swedish speaking school in a strongly Finnish dominated environment in the south of Finland. In the material, mainly consisting of video recorded lessons in forms one to three, the interaction between the pupils and the teachers is analysed. Building on a social constructionist perspective, where learning is regarded as a social phenomenon, situated and visible in changing participation, sequences where pupils or teachers make the language relevant are emphasised. The sequences are analysed in line with the conversation analytic (CA) approach. A fundamental result is an understanding of a monolingual classroom discourse, jointly constructed by teachers and pupils and visible in the pupils' interactionally problematized code-switching. This means that the pupils are not victims of a top-driven language policy; they are active co-constructors of the monolingual discourse. Through different repair initiations the pupils are doing interactional work in positioning themselves correctly in the monolingual discourse, which they simultaneously maintain. This work has a price in relation to time, knowledge and exactness. The pupils' problematized code-switching is often directly and shortly repaired by the teachers. This kind of repair promotes the pupils' participation and is not, as opposed to the results of research in everyday talk, dispreferred in pupil-teacher talk. When the pupils use the possibility to, in a comparatively easy way, participate and thus express their knowledge through codeswitching, and simultaneously talk a monolingual discourse into being, the teacher can, through direct repair, show an understanding in regard to the content, facilitate language learning and simultaneously confirm the pupils as competent speakers and bilingual individuals. Furthermore, significant results show that the monolingual norm has a function of a contrasting background which gives the pupils and the teachers a possibility to use language alternation as a functional and meaningful activity. The pupils use codeswitching as a way of protesting or expressing non-participation in the classroom talk. By making the pupils' bilingualism relevant, the teachers express understanding and empathy and encourage the pupils' participation in the classroom talk. Bilingualism is a nonpreferred, but functioning, resource in the interaction between pupils and teachers.
