Kaukolämpöjohdon lämpöhäviöiden talteenotto lämpöpumpputeknologian avulla

Tämän tutkimuksen tavoitteena oli laatia tarkastelumalli, jonka perusteella pystyttäisiin analysoimaan tutkimuksessa tarkasteltavan kaukolämpöjohdon lämpöhäviöiden talteenot-toratkaisun taloudellista kannattavuutta yleisellä tasolla sekä sen mahdollisissa sovellus-kohteissa. Työssä tarkastellaan kaukolämpöjohtoa, jonka sisään on sijoitettu lämmönke-ruuputki. Lämmönkeruuputken on tarkoitus kerätä lämpöä kaukolämpöjohdon vaipasta sekä pitää vaipan lämpötilaa ympäristön lämpötilaa matalampana, jolloin johdon ulkopuo-lisia lämpöhäviöitä ei synny. Tarkastelumalli laadittiin perustuen lämpöpumppuprosessin ja kaukolämpöverkoston yleisiin mitoitusperiaatteisiin sekä ratkaisuun liittyvien järjestelmien osalta kerättyihin tarkas-teluhetkeä edustaviin kustannustietoihin. Tarkastelumallista laadittiin Excel-laskentataulukkona, jota voidaan tulevaisuudessa soveltaa järjestelmän sovelluskohdekoh-taiseen tarkasteluun sekä mitoitukseen. Lasketut takaisinmaksuajat osoittautuivat kaikissa tarkastelluissa tapauksissa järjestelmien arvioitua teknistä käyttöikää lyhyemmäksi. Järjestelmällä voisi olla tietynlaisissa sovellus-kohteissa myös strateginen, kaukolämpöliiketoiminnan riskejä vähentävä merkitys.

Container logistic innovations in forest-energy sector: Markets, future service concepts and technical improvements

The report presents the results of the commercialization project called the Container logistic services for forest bioenergy. The project promotes new business that is emerging around overall container logistic services in the bioenergy sector. The results assess the European markets of the container logistics for biomass, enablers for new business creation and required service bundles for the concept. We also demonstrate the customer value of the container logistic services for different market segments. The concept analysis is based on concept mapping, quality function deployment process (QFD) and business network analysis. The business network analysis assesses key shareholders and their mutual connections. The performance of the roadside chipping chain is analysed by the logistic cost simulation, RFID system demonstration and freezing tests. The EU has set the renewable energy target to 20 % in 2020 of which Biomass could account for two-thirds. In the Europe, the production of wood fuels was 132.9 million solid-m3 in 2012 and production of wood chips and particles was 69.0 million solidm3. The wood-based chips and particle flows are suitable for container transportation providing market of 180.6 million loose- m3 which mean 4.5 million container loads per year. The intermodal logistics of trucks and trains are promising for the composite containers because the biomass does not freeze onto the inner surfaces in the unloading situations. The overall service concept includes several packages: container rental, container maintenance, terminal services, RFID-tracking service, and simulation and ERP-integration service. The container rental and maintenance would provide transportation entrepreneurs a way to increase the capacity without high investment costs. The RFID-concept would lead to better work planning improving profitability throughout the logistic chain and simulation supports fuel supply optimization.

Analysis of outliers in electricity spot prices with exampleof New England and New Zealand markets

Electricity spot prices have always been a demanding data set for time series analysis, mostly because of the non-storability of electricity. This feature, making electric power unlike the other commodities, causes outstanding price spikes. Moreover, the last several years in financial world seem to show that ’spiky’ behaviour of time series is no longer an exception, but rather a regular phenomenon. The purpose of this paper is to seek patterns and relations within electricity price outliers and verify how they affect the overall statistics of the data. For the study techniques like classical Box-Jenkins approach, series DFT smoothing and GARCH models are used. The results obtained for two geographically different price series show that patterns in outliers’ occurrence are not straightforward. Additionally, there seems to be no rule that would predict the appearance of a spike from volatility, while the reverse effect is quite prominent. It is concluded that spikes cannot be predicted based only on the price series; probably some geographical and meteorological variables need to be included in modeling.

Kansainvälistyvässä ohjelmistoliiketoiminnassa valittavan kumppanin ominaisuudet ja kartoittaminen

Tämän pro gradu tutkielman tavoitteena oli selvittää ominaisuudet, joita ohjelmistoalan yrityksen kansainvälistymisessä tukevalla kumppanilla tulee olla. Tarkoituksena oli selvittää mainitut ominaisuudet yleisesti ja luoda työkalu, jonka avulla potentiaalisia kumppaneita on mahdollista arvioida. Tämän lisäksi ominaisuuksia tarkennettiin tutkielman empiirisessä osassa, jossa kansainvälisen kumppanin ominaisuuksia selvitettiin tapauskohtaisesti tutkielman kohdeyrityksen, CAD Oy:n tilanteessa. Tutkielma jakautuu teoreettiseen ja empiiriseen osaan. Ensimmäinen pohjautuu aikaisempaan tutkimukseen ja kirjallisuuteen kansainvälistymisestä, kohdemaiden valinnasta ja kumppanuuksista. Jälkimmäinen on laadullista tapaustutkimusta. Empiriassa selvitettiin CAD Oy:n kansainväliseltä kumppanilta vaadittavat ominaisuudet ja kartoitettiin naita ominaisuuksia omaavia potentiaalisia yhteistyökumppaneita tutkimuksen kohdemaista. Empiirinen tutkimus perustui kohdeyrityksen johdolle ja henkilöstölle tehtyihin haastatteluihin sekä verkkomateriaaliin. Empiiriseen tutkimukseen liitettiin kohdeyrityksen toiveesta myös kohdemaiden analyysia. Johtopaatoksena todettiin, ettei ole olemassa tiettyjä kriteereitä tai ominaisuuksia, joiden vaatimukset täyttämällä olisi mahdollista löytää sopiva kumppani jokaiseen tilanteeseen. Ominaisuudet on aina määriteltävä tapaus ja yrityskohtaisesti. Niihin vaikuttavat myös laajentumisen kohdemaan ominaispiirteet. Usein kumppanin toivotaan olevan luotettava, ja sen tulisi voida tarjota komplementaarista osaamista liittyen joko myyntiin ja markkinointiin tai teknologiseen osaamiseen. Sen on lisäksi tunnettava paikalliset toimintatavat ja kyettävä huolehtimaan asiakkaista ja heidän vaatimastaan tuesta. Erikoisvaatimuksia asettavat tuotteiden ominaisuudet ja lokalisointivaatimukset.

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.

Developing markets of energy biomass – local and global perspectives

The thesis explores global and national-level issues related to the development of markets for biomass for energy. The thesis consists of five separate papers and provides insights on selected issues. The aim of Paper I was to identify methodological and statistical challenges in assessing international solid and liquid biofuels trade and provide an overview of the Finnish situation with respect to the status of international solid and liquid biofuels trade. We found that, for the Finnish case, it is possible to qualify direct and indirect trade volumes of biofuels. The study showed that indirect trade of biofuels has a highly significant role in Finland and may be a significant sector also in global biofuels trade. The purpose of Paper II was to provide a quantified insight into Finnish prospects for meeting the national 2020 renewable energy targets and concurrently becoming a largescale producer of forest-biomass-based second-generation biofuels for feeding increasing demand in European markets. We found that Finland has good opportunities to realise a scenario to meet 2020 renewable energy targets and for large-scale production of wood-based biofuels. The potential net export of transport biofuels from Finland in 2020 would correspond to 2–3% of European demand. Paper III summarises the global status of international solid and liquid biofuels trade as illuminated by several separate sources. International trade of biofuels was estimated at nearly 1 EJ for 2006. Indirect trade of biofuels through trading of industrial roundwood and material by-products comprises the largest proportion of the trading, with a share of about two thirds. The purpose of Paper IV was to outline a comprehensive picture of the coverage of various certification schemes and sustainability principles relating to the entire value-added chain of biomass and bioenergy. Regardless of the intensive work that has been done in the field of sustainability schemes and principles concerning use of biomass for energy, weaknesses still exist. The objective of Paper V was to clarify the alternative scenarios for the international biomass market until 2020 and identify the underlying steps needed toward a wellfunctioning and sustainable market for biomass for energy purposes. An overall conclusion drawn from this analysis concerns the enormous opportunities related to the utilisation of biomass for energy in the coming decades.

Cooperative strategy in emerging markets - analysis of interfirm r&d cooperation and performance in Russian manufacturing companies

Emerging markets have come to play a significant role in the world, not only due to their strong economic growth but because they have been able to foster an increasing number of innovative high technology oriented firms. However, as the markets continue to change and develop, there remain many companies in emerging markets that struggle with their competitiveness and innovativeness. To improve competitive capabilities, many scholars have come to favor interfirm cooperation, which is perceived to help companies access new knowledge and complementary resources and, by so doing, enables them to catch up quickly with Western competitors. Regardless of numerous attempts by strategic management scholars, the research field remains very fragmented and lacks understanding on how and when interfirm cooperation contributes to firm performance and competiveness in emerging markets. Furthermore, the reasons why interfirm R&D sometimes succeeds but fails at other times frequently remain unidentified. This thesis combines the extant literature on competitive and cooperative strategy, dynamic capabilities, and R&D cooperation while studying interfirm R&D relationships in and between Russian manufacturing companies. Employing primary survey data, the thesis presents numerous novel findings regarding the effect of R&D cooperation and different types of R&D partner on firms’ exploration and exploitation performance. Utilizing a competitive strategy framework enables these effects to be explained in more detail, and especially why interfirm cooperation, regardless of its potential, has had a modest effect on the general competitiveness of emerging market firms. This thesis contributes especially to the strategic management literature and presents a more holistic perspective on the usefulness of cooperative strategy in emerging markets. It provides a framework through which it is possible to assess the potential impacts of different R&D cooperation partners and to clarify the causal relationships between cooperation, performance, and long term competitiveness.

Catching up with competitiveness in emerging markets – An analysis of the role of the firm’s technology management strategies

Emerging markets have experienced rapid economic growth, and manufacturing firms have had to face the effects of globalisation. Some of the major emerging economies have been able to create a supportive business environment that fosters innovation, and China is a good example of a country that has been able to increase value-added investments. Conversely, when we look at Russia, another big emerging market, we witness a situation in which domestic firms struggle more with global competitiveness. Innovation has proven to be one of the most essential ingredients for firms aiming to grow and become more competitive. In emerging markets, the business environment sets many constraints for innovation. However, open strategic choices in new product development enable companies in emerging markets to expand their resource base and capability building. Networking and close inter-firm cooperation are essential in this regard. In this dissertation, I argue that technology transfer is one of the key tools for these companies to become internationally networked and to improve their competitiveness. It forces companies to reach outside the company and national borders, which in many cases, is a major challenge for firms in emerging markets. This dissertation focuses on how companies can catch up with competitiveness in emerging markets. The empirical studies included in the dissertation are based on analyses of survey data mainly of firms and their strategies in the Russian manufacturing industry. The dissertation contributes to the current strategic management literature by further investigating technology management strategies in manufacturing firms in emerging markets and the benefits of more open approaches to new product development and innovation.

New directions in Stochastic Multicriteria Acceptability Analysis

Decisions taken in modern organizations are often multi-dimensional, involving multiple decision makers and several criteria measured on different scales. Multiple Criteria Decision Making (MCDM) methods are designed to analyze and to give recommendations in this kind of situations. Among the numerous MCDM methods, two large families of methods are the multi-attribute utility theory based methods and the outranking methods. Traditionally both method families require exact values for technical parameters and criteria measurements, as well as for preferences expressed as weights. Often it is hard, if not impossible, to obtain exact values. Stochastic Multicriteria Acceptability Analysis (SMAA) is a family of methods designed to help in this type of situations where exact values are not available. Different variants of SMAA allow handling all types of MCDM problems. They support defining the model through uncertain, imprecise, or completely missing values. The methods are based on simulation that is applied to obtain descriptive indices characterizing the problem. In this thesis we present new advances in the SMAA methodology. We present and analyze algorithms for the SMAA-2 method and its extension to handle ordinal preferences. We then present an application of SMAA-2 to an area where MCDM models have not been applied before: planning elevator groups for high-rise buildings. Following this, we introduce two new methods to the family: SMAA-TRI that extends ELECTRE TRI for sorting problems with uncertain parameter values, and SMAA-III that extends ELECTRE III in a similar way. An efficient software implementing these two methods has been developed in conjunction with this work, and is briefly presented in this thesis. The thesis is closed with a comprehensive survey of SMAA methodology including a definition of a unified framework.

Market potentialfor free-cutting steels in Europe

Työn tavoitteena oli selvittää tilannetta Euroopan automaattiteräsmarkkinoilla ja sen perusteella arvioida Imatra Steelin mahdollisuuksia kilpailla kyseessä olevilla markkinoilla. Tärkein tavoite oli kokonaismarkkinapotentiaalin arvioiminen Saksan, Ruotsin, Englannin ja Suomen markkinoilla. Lisäksi selvitettiin käytetyt automaattiteräslajit ja mitta-alue, hintataso sekä koneistukseenliittyviä teknisiä yksityiskohtia.Tavoitteena oli myös kartoittaa asenteita ja mielipiteitä mahdollisesta lyijyn käytön kieltämisestä teräksen seosaineena tulevaisuudessa. Paremman kokonaiskuvan saamiseksi analysoitiin myös kilpailutilannetta Euroopassa. Työn teoriakehyksessä tutkittiin teollisuustuotteiden markkinatutkimuksen suorittamisen erityispiirteitä, markkinapotentiaalin määrittämiseen liittyviä käsitteitä ja kilpailija-analyysin suorittamista. Empiirinen tutkimus suoritettiin pääasiassa asiantuntijoiden haastattelujen ja kyselyjen avulla. Haastateltavina oli tukkureita ja loppukäyttäjiä. Kilpailutilanteen kartoittaminen perustuu lähinnä sekundääriseen tietoon, Internet-sivuihin ja myyntikonttoreiden aikaisemmin keräämään tietoon.Automaattiterästen kokonaispotentiaaliksi Euroopassa arvioitiin miljoona tonnia ja suurin osa kaupasta käydään tutkituilla markkina-alueilla. Suurimmat volyymit sijoittuvat pienemmille mitta-alueille, Æ 12 - 50 mm. Markkinoita hallitsee muutama suuri teräksen valmistaja. Imatra Steel kohtuullisen pienenä toimittajana ei pysty kilpailemaan volyymilla ja tuotevalikoimallaan suurten teräsjättien kanssa. Imatra Steelin mahdollinen strategiavaihtoehto olisi yrittää löytää ne kapeat segmentit ja markkinaraot, joilla sen tuotteet jatietotaito tuovat asiakkaalle suurimman mahdollisen hyödyn verrattuna kilpailijoihin.

Sähkökaupan riskit ja riskienhallinta

Diplomityön tavoitteena on luoda kokonaisvaltainen kuva sähkökaupassa esiintyvistä riskeistä ja niiden analysointi- sekä hallintamenetelmistä. Toinen päätavoitteista on lisätä ymmärrystä markkinoiden erikoispiirteistä, kuten siirtokapasiteettirajoituksista, kysynnän hintajouston puutteesta ja markkinoiden keskittyneisyydestä, sekä arvioida niiden merkitystä sähkökaupan riskienhallinnan näkökulmasta. Markkinoiden erikoispiirteet ja sähkön tuotantoon ja kulutukseen vaikuttavat fundamentaaliset tekijät aiheuttavat suuria muutoksia pörssisähkön hintatasossa. Sähkön volatiliteetti yhdessä useiden muiden riskitekijöiden kanssa aiheuttaa sähkökaupantoimijoille todellisen tarpeen riskienhallinnalle. Sähkökauppa tarjoaa haasteellisen toimintaympäristön riskienhallinnan näkökulmasta. Sähkökaupassa esiintyvien riskien täydellinen hallitseminen on miltei mahdoton tehtävä, mutta sähkökaupan toimintaympäristön tunteminen ja järjestelmällisesti toteutettu riskienhallinta luovat hyvät edellytykset menestyksekkäälle toiminnalle sähkökaupassa. Diplomityössä käsitellään sähkökaupassa esiintyviä riskejä ja niidensyntyyn vaikuttavia tekijöitä. Näiden asioiden ymmärtäminen luo pohjan sähkökaupan onnistuneelle riskienhallinnalle. Työssä käydään myös läpi yleisimmät sähkökaupassa käytetyt riskianalyysin menetelmät. Diplomityössä esitellään sähköpörssin tarjoamat johdannaistuotteet ja havainnollistetaan niiden käyttöä osana sähkökaupan riskienhallintaa. Työn lopussa käsitellään profiiliriskin muodostumista jasen vaikutuksia sähkön hankintakustannuksiin.

Relative Technical Efficiency of European Transportation Systems

Talouden kasvaessa myös tavarankuljetusmäärät kasvavat. Kuljetusjärjestelmät ja niiden sujuva toiminta on erittäin tärkeää taloudellisen kasvun kannalta tällä hetkellä, ja se tulee olemaan yhä tärkeämpää tulevaisuudessa. Tulevaisuudessa tarvitaan kokonaisvaltainen ja selkeästi tehokkaampi kuljetusjärjestelmä, mikäli tulevaisuuden kuljetusvirrat halutaan hoitaa kestävästi. Tässä opinnäytetyössäni tutkin kolmen eurooppalaisen kuljetusjärjestelmän (rautatiet, lentoliikenne ja konttiliikenne meritse) suhteellista teknistä tehokkuutta ja menetelmänä on data envelopment analysis (DEA). Vertailtaessa kuljetusjärjestelmiä löytyi suuria eroja kuljetusmuotojen välille. lentoyhtiöt suoriutuivat huomattavan tasaisesti eli tehokkaiden ja ei-tehokkaiden toimijoiden välillä ei ollut suuria eroja. Rautatiepuolella erot venyivät huomattavan suuriksi niin eri yritysten välillä kuin jopa saman yrityksen sisällä eri vuosina. Pikaisemmassa laivayhtiöiden tarkastelussa erot niiden välillä olivat lähes yhtä pieniä kuin lentoyhtiöiden välillä. Tarkasteltaessa omistajuuden vaikutusta lentoyhtiöiden toiminnassa huomattiin, että yksityisessä omistuksessa olevat yritykset olivat huomattavasti tehokkaampia matkustajien kuljettamisessa. Rahtipuolella merkittäviä eroja ei havaittu. Merkittävät korrelaatiot eri mallien välillä antoivat joitain viitteitä myös kuljetuspoliittiseen päätöksentekoon; investoinnit matkustajienkuljetuksiin raiteilla parantaisivat koko rautatiepuolen teokkuutta, mutta myös samalla lentopuolen matkustajakuljetuksen tehokkuutta.
