Tämä työ tehtiin Kone Industrial Oy:lle Major Projects yksikköön, laatuosastolle. Kone Major Projects yksikkö keskittyy erikoisiin ja suuriin hissi- ja liukuporras projekteihin. Työn tavoitteena oli luoda harmonisoitu prosessi hissikomponenttien laaduntarkkailua varten sekä tarkastella ja vertailla kustannussäästöjä, jota tällä uudella prosessilla voidaan saavuttaa. Tavoitteena oli saavuttaa 80-prosentin kustannussäästöt laatukustannuksissa uuden laatuprosessin avulla. Työn taustana ja tutkimusongelmana ovat lisääntyneet erikoisprojektit ja niiden myötä lisääntynyt laaduntarkkailun tarve. Ongelmana laaduntarkkailussa voitiin pitää harmonisoidun ja selkeän prosessin puuttumista C-prosessikomponenttien valmistuksessa. Lisäksi kehitysprosessin aikana luotiin vanhojen työkalujen pohjalta keskeinen laaduntarkkailutyökalu, CTQ-työkalu. Työssä käsitellään ensin Konetta yhtiönä ja selvitetään Koneen keskeisimmät prosessit työn taustaksi. Teoria osuudessa käsitellään prosessin kehitykseen liittyviä teorioita sekä yleisiä laatukäsitteitä ja esitetään teorioita laadun asemasta nykypäivänä. Lopuksi käsitellään COQ eli laatukustannusten teoriaa ja esitellään teoria PAF-analyysille, jota käytetään työssä laatukustannusten vertailuun case esimerkin avulla. Työssä kuvataan CTQ prosessin luominen alusta loppuun ja case esimerkin avulla testataan uutta CTQ prosessia pilottihankkeessa. Tässä case esimerkissä projektin bracket eli johdekiinnitysklipsi tuotetaan uuden laatuprosessin avulla sekä tehdään kustannusvertailu saman projektin toisen bracketin kanssa, joka on tuotettu ennen uuden laatuprosessin implementoimista. Työn lopputuloksena CTQ prosessi saatiin luotua ja sitä pystyttiin testaamaan käytännössä case esimerkin avulla. Tulosten perusteella voidaan sanoa, että CTQ prosessin käyttö vähentää laatukustannuksia huomattavasti ja helpottaa laadunhallintaa C-prosessikomponenttien tuotannossa.

The goal of this thesis is to make a case study of test automation’s profitability in the development of embedded software in a real industrial setting. The cost-benefit analysis is done by considering the costs and benefits test automation causes to software development, before the software is released to customers. The potential benefits of test automation regarding software quality after customer release were not estimated. Test automation is a significant investment which often requires dedicated resources. When done accordingly, the investment in test automation can produce major cost savings by reducing the need for manual testing effort, especially if the software is developed with an agile development framework. It can reduce the cost of avoidable rework of software development, as test automation enables the detection of construction time defects in the earliest possible moment. Test automation also has many pitfalls such as test maintainability and testability of the software, and if those areas are neglected, the investment in test automation may become worthless or it may even produce negative results. The results of this thesis suggest that test automation is very profitable at the company under study.

European luxury brands have an image of manufacturing their products in the same country where the brands originate. However, in the past years many luxury brands have shifted their manufacturing to countries outside Europe. China is now a common manufacturing country for European luxury brands despite the country’s poor image as a manufacturer. Chinese manufacturing is often associated with bad quality, bad labour conditions, mass production, and counterfeits. The image of China does not quite match the image luxury brands enjoy including characteristics such as high end quality, craftsmanship, details, design, or premium price. A negatively perceived country-of-manufacture may have an effect on a brand’s image and consumers’ purchase decisions. This thesis is focused on European luxury brands manufacturing in China, and how this effects the brand image and purchase decisions among luxury consumers. The empirical part of this thesis is based on focus group research, which is a popular method in the field of qualitative research. The main focus group is female luxury consumers in Finland. This main group has been divided into three categories: 1) the university students, 2) the young career women, 3) the experienced luxury consumers. This categorization has been done based on their different stages in luxury consumption. All in all, the empirical research consisted of 11 interviews and 29 participants. The main contribution of this thesis was that there is a difference between the opinions of the younger groups (university students and young career women) and the experienced luxury consumers when discussing the effect of country-of-manufacture on brand image and purchase decisions of luxury brands. The younger participants thought that manufacturing luxury products in China might affect the brand image, but their purchase decisions would not be that much affected by the country-of-origin. The experienced luxury consumers had quite a different view on the country-of-origin of luxury brands – they found it an important decisive factor prior making purchases. The majority of experienced luxury consumers would not buy luxury products made in China, and they would always check where these products are made in.

Työn tavoitteena oli tutkia, millä tavalla perusterveydenhuollon perinteisestä terveysasemamallista hyvinvointiasemamalliin siirtyminen vaikuttaa sosiaali- ja terveyspalvelujen tarjonnan kustannuksiin, mikäli vaikutus on havaittavissa. Toisaalta tavoitteena oli kartoittaa, millä keinoilla hyvinvointiasemien kustannustehokkuutta voitaisiin parantaa tulevaisuudessa ja mitä kustannushyötyjä tiiviimmällä sosiaali- ja terveystoimen yhteistyöllä on mahdollista saavuttaa. Tutkimuksessa käsiteltiin terveyden ja hyvinvoinnin edistämisen roolin merkitystä perusterveydenhuollossa, sähköistä asiointipalveluja ja terveydenhuollon ammattiryhmien välistä työnjakoa sekä edelleen, miten näillä voidaan vaikuttaa tuottavuuteen ja vaikuttavuuteen. Havaittiin, että sähköisellä asioinnilla ja työnjaolla on selkeä yhteys kustannuksiin. Työn empiirisessä osassa tarkasteltiin kolmea hyvinvointiasemamallin pilottihankkeessa mukana olevaa asemaa Lauritsalassa, Lemillä ja Ruokolahdella. Kustannusten tarkastelu keskittyi henkilöstö- ja tilakustannuksiin. Tutkittiin myös, miten sähköinen asiointi ja Eksoten alueen puhelinpalvelujen keskittäminen vaikuttaa edellä mainittuihin kustannuseriin. Tutkimuksen tuloksina havaittiin, että hyvinvointiasemamallin pilotointi ei ole tutkittavilla asemilla merkittävästi vaikuttanut kustannuksiin henkilöstön osalta; tilakustannukset olivat pienentyneet Lemillä ja Ruokolahdella. Laskelmien perusteella muodostettujen tavoitteiden mukaisesti on hyvinvointiasemilla kuitenkin pyrittävä vähintään noin 14 % tai enintään 32 % säästöön henkilöstö- ja tilakustannuksissa pilottivaiheen kustannuksiin verrattuna. Tulevaisuudessa olennaiseksi kustannusten hallinnan edellytykseksi havaittiin työnjaon muuttaminen hoitajavetoisemmaksi ja sähköisten asiointipalvelujen lisääntyvä tarjonta. Sähköisten asioinnin lisääntyvällä käytöllä on mahdollista vähentää hoitohenkilöstön tarvetta kokonaisuudessaan. Sekä sähköisen asioinnin käytön lisäämisellä että puhelinpalvelujen keskittämisellä tulevaisuudessa havaittiin olevan huomattava vaikutus henkilöstöresurssien käyttöön ja edelleen kustannustehokkuuteen.

Työn tavoitteena oli kehittää case-yrityksen kustannuslaskentamallia tilanteessa, jossa yrityksen tuotanto muuttuu merkittävästi suuren tuotantoinvestoinnin vaikutuksesta. Työ koostuu teoreettisesta kirjallisuuskatsauksesta ja sitä soveltavasta empiirisestä case-tutkimuksesta. Tarkastelun kohteena on yrityksen nykyinen kustannuslaskentamalli ja sen ongelmat. Näitä ongelmia pyritään ratkaisemaan hahmottelemalla uuden kustannuslaskentamallin perusteita. Merkittävin muutos kustannuslaskennassa tapahtui erityisesti välillisten kustannusten allokoinnin kohdalla, jossa useassa merkittävässä kustannuserässä pystyttiin löytämään tapa allokoida kustannukset jopa tuotteille asti. Empiriassa teoriapohjana käytettiin pääasiassa Robert Kaplanin vuonna 2004 luomaa toimintokohtaisen kustannuslaskennan kehittyneempää mallia (TDACB). Case-yrityksen kustannuslaskenta oli perustunut aiemmin standardikustannuslaskentaan ja huomattavien yleiskustannuskertoimien käyttöön. Kehittämällä kustannuslaskentaa, voidaan estää virheellisten päätösten tekeminen ja antaa koko organisaatiolle parempaa kustannusinformaatiota

Heikkenevä kysyntä sekä koveneva hintakilpailu erityisesti painopaperin markkinoilla on luonut paperinvalmistajalle haasteita kustannusten alentamisen sekä kannattavuuden parantamisen osalta. Sijaintinsa vuoksi yritys on halunnut erityisesti parantaa kustannustehokkuuttaan logistiikan osalta, minkä tueksi tämä diplomityö on tehty. Tutkimuksen tarkoituksena on analysoida paperitehtaan toimitusketjuja kustannusjohtamisen näkökulmasta. Tavoitteena on ollut arvioida kahden vaihtoehtoisen toimitusketjun, suoran ja välivarasto-toimituksen, vaikutusta syntyvien kustannusten, ketjuun sitoutuneen pääoman sekä asiakaskannattavuuden kautta. Tutkimus toteutettiin case-tutkimuksen kaltaisena soveltuvin osin, hyödyntämällä kvantitatiivisia menetelmiä. Projektia varten valittiin paperinvalmistajan painopaperin tuloslinjalta kymmenen kohdeasiakasta, joille vaihtoehtoisia toimitusketjuja voidaan soveltaa. Toimitusketjut rajattiin käsittämään valmiin tuotteen asiakastoimitukset ja niistä aiheutuvat kuluerät. Kustannus- ja pääoma-analyysin suunnittelussa hyödynnettiin toimitusketjuihin sekä kustannusjohtamiseen liittyvää teoreettista kirjallisuutta. Ensisijaisena viitekehyksenä kustannusten analysoinnissa sovellettiin toimintolaskentaa ja pääoman sitoutumisen arvioinnissa kiertoajan tunnuslukuja. Käsiteltävä informaatio kerättiin yrityksen sisäisistä raporteista sekä toiminnanohjausjärjestelmästä taulukkolaskentaohjelmaan, jossa laskelmat tehtiin. Tutkimuksen avaintuloksena kahdeksan case-asiakkaan kohdalla suora toimitus osoittautui kustannuksiltaan välivaraston kautta kulkevaa edullisemmaksi. Lisäksi havaittiin suoran toimituksen nopeuttavan teoriassa pääoman kiertoa toimitusketjussa lyhyemmän läpimenoajan ansiosta. Johtopäätöksenä kustannus- ja pääomahyötyjen vaikutuksen vuoksi suorien toimitusten hyödyntäminen on edullista soveltuvien asiakkaiden kohdalla. Tutkimuksessa kustannusinformaation kerääminen kokonaisvaltaisesti osoittautui haasteelliseksi, sillä kaikkien toimitusketjun kustannuserien tietoja ei ollut laajasti saatavilla. Toimeksiantajan näkökulmasta merkittävät kohteet jatkotutkimukselle ovat kustannusten oikeellisuuteen ja kohdistamiseen sekä asiakkaiden maksukäytäntöihin ja ehtoihin liittyvä seuranta.

Electrical machine drives are the most electrical energy-consuming systems worldwide. The largest proportion of drives is found in industrial applications. There are, however many other applications that are also based on the use of electrical machines, because they have a relatively high efficiency, a low noise level, and do not produce local pollution. Electrical machines can be classified into several categories. One of the most commonly used electrical machine types (especially in the industry) is induction motors, also known as asynchronous machines. They have a mature production process and a robust rotor construction. However, in the world pursuing higher energy efficiency with reasonable investments not every application receives the advantage of using this type of motor drives. The main drawback of induction motors is the fact that they need slipcaused and thus loss-generating current in the rotor, and additional stator current for magnetic field production along with the torque-producing current. This can reduce the electric motor drive efficiency, especially in low-speed, low-power applications. Often, when high torque density is required together with low losses, it is desirable to apply permanent magnet technology, because in this case there is no need to use current to produce the basic excitation of the machine. This promotes the effectiveness of copper use in the stator, and further, there is no rotor current in these machines. Again, if permanent magnets with a high remanent flux density are used, the air gap flux density can be higher than in conventional induction motors. These advantages have raised the popularity of PMSMs in some challenging applications, such as hybrid electric vehicles (HEV), wind turbines, and home appliances. Usually, a correctly designed PMSM has a higher efficiency and consequently lower losses than its induction machine counterparts. Therefore, the use of these electrical machines reduces the energy consumption of the whole system to some extent, which can provide good motivation to apply permanent magnet technology to electrical machines. However, the cost of high performance rare earth permanent magnets in these machines may not be affordable in many industrial applications, because the tight competition between the manufacturers dictates the rules of low-cost and highly robust solutions, where asynchronous machines seem to be more feasible at the moment. Two main electromagnetic components of an electrical machine are the stator and the rotor. In the case of a conventional radial flux PMSM, the stator contains magnetic circuit lamination and stator winding, and the rotor consists of rotor steel (laminated or solid) and permanent magnets. The lamination itself does not significantly influence the total cost of the machine, even though it can considerably increase the construction complexity, as it requires a special assembly arrangement. However, thin metal sheet processing methods are very effective and economically feasible. Therefore, the cost of the machine is mainly affected by the stator winding and the permanent magnets. The work proposed in this doctoral dissertation comprises a description and analysis of two approaches of PMSM cost reduction: one on the rotor side and the other on the stator side. The first approach on the rotor side includes the use of low-cost and abundant ferrite magnets together with a tooth-coil winding topology and an outer rotor construction. The second approach on the stator side exploits the use of a modular stator structure instead of a monolithic one. PMSMs with the proposed structures were thoroughly analysed by finite element method based tools (FEM). It was found out that by implementing the described principles, some favourable characteristics of the machine (mainly concerning the machine size) will inevitable be compromised. However, the main target of the proposed approaches is not to compete with conventional rare earth PMSMs, but to reduce the price at which they can be implemented in industrial applications, keeping their dimensions at the same level or lower than those of a typical electrical machine used in the industry at the moment. The measurement results of the prototypes show that the main performance characteristics of these machines are at an acceptable level. It is shown that with certain specific actions it is possible to achieve a desirable efficiency level of the machine with the proposed cost reduction methods.

Transportation plays a major role in the gross domestic product of various nations. There are, however, many obstacles hindering the transportation sector. Cost-efficiency along with proper delivery times, high frequency and reliability are not a straightforward task. Furthermore, environmental friendliness has increased the importance of the whole transportation sector. This development will change roles inside the transportation sector. Even now, but especially in the future, decisions regarding the transportation sector will be partly based on emission levels and other externalities originating from transportation in addition to pure transportation costs. There are different factors, which could have an impact on the transportation sector. IMO’s sulphur regulation is estimated to increase the costs of short sea shipping in the Baltic Sea. Price development of energy could change the roles of different transport modes. Higher awareness of the environmental impacts originating from transportation could also have an impact on the price level of more polluting transport modes. According to earlier research, increased inland transportation, modal shift and slowsteaming can be possible results of these changes in the transportation sector. Possible changes in the transportation sector and ways to settle potential obstacles are studied in this dissertation. Furthermore, means to improve cost-efficiency and to decrease environmental impacts originating from transportation are researched. Hypothetical Finnish dry port network and Rail Baltica transport corridor are studied in this dissertation. Benefits and disadvantages are studied with different methodologies. These include gravitational models, which were optimized with linear integer programming, discrete-event and system dynamics simulation, an interview study and a case study. Geographical focus is on the Baltic Sea Region, but the results can be adapted to other geographical locations with discretion. Results indicate that the dry port concept has benefits, but optimization regarding the location and the amount of dry ports plays an important role. In addition, the utilization of dry ports for freight transportation should be carefully operated, since only a certain amount of total freight volume can be cost-efficiently transported through dry ports. If dry ports are created and located without proper planning, they could actually increase transportation costs and delivery times of the whole transportation system. With an optimized dry port network, transportation costs can be lowered in Finland with three to five dry ports. Environmental impacts can be lowered with up to nine dry ports. If more dry ports are added to the system, the benefits become very minor, i.e. payback time of investments becomes extremely long. Furthermore, dry port network could support major transport corridors such as Rail Baltica. Based on an analysis of statistics and interview study, there could be enough freight volume available for Rail Baltica, especially, if North-West Russia is part of the Northern end of the corridor. Transit traffic to and from Russia (especially through the Baltic States) plays a large role. It could be possible to increase transit traffic through Finland by connecting the potential Finnish dry port network and the studied transport corridor. Additionally, sulphur emission regulation is assumed to increase the attractiveness of Rail Baltica in the year 2015. Part of the transit traffic could be rerouted along Rail Baltica instead of the Baltic Sea, since the price level of sea transport could increase due to the sulphur regulation. Both, the hypothetical Finnish dry port network and Rail Baltica transport corridor could benefit each other. The dry port network could gain more market share from Russia, but also from Central Europe, which is the other end of Rail Baltica. In addition, further Eastern countries could also be connected to achieve higher potential freight volume by rail.

This thesis discusses the basic problem of the modern portfolio theory about how to optimise the perfect allocation for an investment portfolio. The theory provides a solution for an efficient portfolio, which minimises the risk of the portfolio with respect to the expected return. A central feature for all the portfolios on the efficient frontier is that the investor needs to provide the expected return for each asset. Market anomalies are persistent patterns seen in the financial markets, which cannot be explained with the current asset pricing theory. The goal of this thesis is to study whether these anomalies can be observed among different asset classes. Finally, if persistent patterns are found, it is investigated whether the anomalies hold valuable information for determining the expected returns used in the portfolio optimization Market anomalies and investment strategies based on them are studied with a rolling estimation window, where the return for the following period is always based on historical information. This is also crucial when rebalancing the portfolio. The anomalies investigated within this thesis are value, momentum, reversal, and idiosyncratic volatility. The research data includes price series of country level stock indices, government bonds, currencies, and commodities. The modern portfolio theory and the views given by the anomalies are combined by utilising the Black-Litterman model. This makes it possible to optimise the portfolio so that investor’s views are taken into account. When constructing the portfolios, the goal is to maximise the Sharpe ratio. Significance of the results is studied by assessing if the strategy yields excess returns in a relation to those explained by the threefactormodel. The most outstanding finding is that anomaly based factors include valuable information to enhance efficient portfolio diversification. When the highest Sharpe ratios for each asset class are picked from the test factors and applied to the Black−Litterman model, the final portfolio results in superior riskreturn combination. The highest Sharpe ratios are provided by momentum strategy for stocks and long-term reversal for the rest of the asset classes. Additionally, a strategy based on the value effect was highly appealing, and it basically performs as well as the previously mentioned Sharpe strategy. When studying the anomalies, it is found, that 12-month momentum is the strongest effect, especially for stock indices. In addition, a high idiosyncratic volatility seems to be positively correlated with country indices on stocks.
