On Doing Successful ICT Business with Russian Manufacturing Enterprises

This Master’s thesis addresses different approaches using which a foreign IT company could enter Russian manufacturing industry with its enterprise information systems and IT services. In order to define the most suitable market entry approach, several aspects related to Russian manufacturing enterprises are studied. These aspects include challenges of doing ICT business with the previously mentioned enterprises, their perception of ICT role and their ICT preferences, as well as their buying behavior related to acquisition of information systems (IS). The study results show that there are several challenges that can be faced by a foreign IT vendor when starting conducting ICT business with Russian manufacturing enterprises. The results also show that Russian manufacturing industry is still rather immature in sense of business process automation, and its IT buying behavior is rather specific and complicated. The results suggest that an efficient way to approach these enterprises is through a network of trusted partners that consists of reliable Russian IS integrators and business consultants having established connections to Russian manufacturing companies and possessing the needed competence.

Possibilities and challenges of longitudinal studies in operations management

Longitudinal studies are quite rare in the area of Operations Management. One reason might be the time needed to conduct such studies, and then the lack of experience and real-life examples and results. The aim of the thesis is to examine longitudinal studies in the area of OM and the possible advantages, challenges and pitfalls of such studies. A longitudinal benchmarking study, Made in Finland, was analyzed in terms of the study methodology and its outcomes. The timeline of this longitudinal study is interesting. The first study was made in 1993, the second in 2004 and the third in 2010. Between these studies some major changes occurred in the Finnish business environment. Between the first and second studies, Finland joined the ETA and the EU, and globalization started with the rise of the Internet era, while between the second and third studies financial turmoil started in 2007. The sample and cases used in this study were originally 23 manufacturing sites in Finland. These sites were interviewed in 1993, in 2004 and 2010. One important and interesting aspect is that all the original sites participated in 2004, and 19 sites were still able to participate in 2010. Four sites had been closed and/or moved abroad. All of this gave a good opportunity to study the changes that occurred in the Finnish manufacturing sites and their environment, and how they reacted to these changes, and the effects on their performance. It is very seldom, if ever, that the same manufacturing sites have been studied in a longitudinal setting by using three data points. The results of this study are thus unique, and the experience gained is valuable for practitioners.

Cloud computing contribution to manufacturing industry

Manufacturing industry has been always facing challenge to improve the production efficiency, product quality, innovation ability and struggling to adopt cost-effective manufacturing system. In recent years cloud computing is emerging as one of the major enablers for the manufacturing industry. Combining the emerged cloud computing and other advanced manufacturing technologies such as Internet of Things, service-oriented architecture (SOA), networked manufacturing (NM) and manufacturing grid (MGrid), with existing manufacturing models and enterprise information technologies, a new paradigm called cloud manufacturing is proposed by the recent literature. This study presents concepts and ideas of cloud computing and cloud manufacturing. The concept, architecture, core enabling technologies, and typical characteristics of cloud manufacturing are discussed, as well as the difference and relationship between cloud computing and cloud manufacturing. The research is based on mixed qualitative and quantitative methods, and a case study. The case is a prototype of cloud manufacturing solution, which is software platform cooperated by ATR Soft Oy and SW Company China office. This study tries to understand the practical impacts and challenges that are derived from cloud manufacturing. The main conclusion of this study is that cloud manufacturing is an approach to achieve the transformation from traditional production-oriented manufacturing to next generation service-oriented manufacturing. Many manufacturing enterprises are already using a form of cloud computing in their existing network infrastructure to increase flexibility of its supply chain, reduce resources consumption, the study finds out the shift from cloud computing to cloud manufacturing is feasible. Meanwhile, the study points out the related theory, methodology and application of cloud manufacturing system are far from maturity, it is still an open field where many new technologies need to be studied.

Offshoring and outsourcing under demand uncertainty -a supply chain management analysis

Outsourcing and offshoring or any combinations of these have not just become a popular phenomenon, but are viewed as one of the most important management strategies due to the new possibilities from globalization. They have been seen as a possibility to save costs and improve customer service. Executing offshoring and offshore outsourcing successfully can be more complex than initially expected. Potential cost savings resulting from of offshoring and offshore outsourcing are often based on lower manufacturing costs. However, these benefits might be conflicted by a more complex supply chain with service level challenges that can respectively increase costs. Therefore analyzing the total cost effects of offshoring and outsourcing is necessary. The aim of this Master´s Thesis was to to construct a total cost model using academic literature to calculate the total costs and analyze the reasonability of offshoring and offshore outsourcing production of a case company compared to insourcing production. The research data was mainly quantitative and collected mainly from the case company past sales and production records. In addition management level interviews from the case company were conducted. The information from these interviews was used for the qualification of the necessary quantitative data and adding supportive information that could not be gathered from the quantitative data. Both data collection and analysis were guided by a theoretical frame of reference that was based on academic literature concerning offshoring and outsourcing, statistical calculation of demand and total costs. The results confirm the theories that offshoring and offshore outsourcing would reduce total costs as both offshoring and offshore outsourcing options result in lower total annual costs than insourcing mainly due to lower manufacturing costs. However, increased demand uncertainty would make the alternative of offshore outsourcing more risky and difficult to manage. Therefore when assessing the overall impact of the alternatives, offshoring is the most preferable option. As the main cost savings in offshore outsourcing came from lower manufacturing costs, more specifically labour costs, the logistics costs in this case company did not have an essential effect in total costs. The management should therefore pay attention initially to manufacturing costs and then logistics costs when choosing the best production sourcing option for the company.

Carbon pricing and its effect on company profitability

In order to reach the 2°C climate target, the carbon price should rise significantly in order for it to be financially rewarding for companies to reduce their emissions. This research aims to find how a significant increase in the carbon price would affect the profitability of companies. Prior research has not found consensus on how regulatory policies affect companies. This research looks at profitability factors of carbon pricing through a mix of related issues such as the carbon risk, carbon pricing mechanisms and cost pass-through of additional costs. The research is quantitative and examines financial data and emissions data regarding scope 1 and scope 2 emissions on 328 European companies. The data analysis method utilised is a sensitivity analysis conducted as a scenario analysis. Different price increases and cost pass-through rates are tested to see how company profitability is affected. As the companies are distributed between 9 sectors and 53 industries, the results vary. The industries that are found to be affected by an increase in carbon pricing show drastic negative changes in profitability. The results complement prior research identifying the most carbon-intensive industries, but also provide some new insights on industries that may be affected by carbon pricing. Industries related to manufacturing, electricity and energy are partly significantly impacted, but also industries related to tourism and food show potential signs of impact when an increased carbon price is introduced.

Activity-based life cycle costing model for cost estimation and monitoring – Case: manned and autonomous dry bulk carrier

Recent developments in automation, robotics and artificial intelligence have given a push to a wider usage of these technologies in recent years, and nowadays, driverless transport systems are already state-of-the-art on certain legs of transportation. This has given a push for the maritime industry to join the advancement. The case organisation, AAWA initiative, is a joint industry-academia research consortium with the objective of developing readiness for the first commercial autonomous solutions, exploiting state-of-the-art autonomous and remote technology. The initiative develops both autonomous and remote operation technology for navigation, machinery, and all on-board operating systems. The aim of this study is to develop a model with which to estimate and forecast the operational costs, and thus enable comparisons between manned and autonomous cargo vessels. The building process of the model is also described and discussed. Furthermore, the model’s aim is to track and identify the critical success factors of the chosen ship design, and to enable monitoring and tracking of the incurred operational costs as the life cycle of the vessel progresses. The study adopts the constructive research approach, as the aim is to develop a construct to meet the needs of a case organisation. Data has been collected through discussions and meeting with consortium members and researchers, as well as through written and internal communications material. The model itself is built using activity-based life cycle costing, which enables both realistic cost estimation and forecasting, as well as the identification of critical success factors due to the process-orientation adopted from activity-based costing and the statistical nature of Monte Carlo simulation techniques. As the model was able to meet the multiple aims set for it, and the case organisation was satisfied with it, it could be argued that activity-based life cycle costing is the method with which to conduct cost estimation and forecasting in the case of autonomous cargo vessels. The model was able to perform the cost analysis and forecasting, as well as to trace the critical success factors. Later on, it also enabled, albeit hypothetically, monitoring and tracking of the incurred costs. By collecting costs this way, it was argued that the activity-based LCC model is able facilitate learning from and continuous improvement of the autonomous vessel. As with the building process of the model, an individual approach was chosen, while still using the implementation and model building steps presented in existing literature. This was due to two factors: the nature of the model and – perhaps even more importantly – the nature of the case organisation. Furthermore, the loosely organised network structure means that knowing the case organisation and its aims is of great importance when conducting a constructive research.

Fabrication and Pseudo-Analog Characteristics of Ta2O5 -Based ReRAM Cell

Memristori on yksi elektroniikan peruskomponenteista vastuksen, kondensaattorin ja kelan lisäksi. Se on passiivinen komponentti, jonka teorian kehitti Leon Chua vuonna 1971. Kesti kuitenkin yli kolmekymmentä vuotta ennen kuin teoria pystyttiin yhdistämään kokeellisiin tuloksiin. Vuonna 2008 Hewlett Packard julkaisi artikkelin, jossa he väittivät valmistaneensa ensimmäisen toimivan memristorin. Memristori eli muistivastus on resistiivinen komponentti, jonka vastusarvoa pystytään muuttamaan. Nimens mukaisesti memristori kykenee myös säilyttämään vastusarvonsa ilman jatkuvaa virtaa ja jännitettä. Tyypillisesti memristorilla on vähintään kaksi vastusarvoa, joista kumpikin pystytään valitsemaan syöttämällä komponentille jännitettä tai virtaa. Tämän vuoksi memristoreita kutsutaankin usein resistiivisiksi kytkimiksi. Resistiivisiä kytkimiä tutkitaan nykyään paljon erityisesti niiden mahdollistaman muistiteknologian takia. Resistiivisistä kytkimistä rakennettua muistia kutsutaan ReRAM-muistiksi (lyhenne sanoista resistive random access memory). ReRAM-muisti on Flash-muistin tapaan haihtumaton muisti, jota voidaan sähköisesti ohjelmoida tai tyhjentää. Flash-muistia käytetään tällä hetkellä esimerkiksi muistitikuissa. ReRAM-muisti mahdollistaa kuitenkin nopeamman ja vähävirtaiseman toiminnan Flashiin verrattuna, joten se on tulevaisuudessa varteenotettava kilpailija markkinoilla. ReRAM-muisti mahdollistaa myös useammin bitin tallentamisen yhteen muistisoluun binäärisen (”0” tai ”1”) toiminnan sijaan. Tyypillisesti ReRAM-muistisolulla on kaksi rajoittavaa vastusarvoa, mutta näiden kahden tilan välille pystytään mahdollisesti ohjelmoimaan useampia tiloja. Muistisoluja voidaan kutsua analogisiksi, jos tilojen määrää ei ole rajoitettu. Analogisilla muistisoluilla olisi mahdollista rakentaa tehokkaasti esimerkiksi neuroverkkoja. Neuroverkoilla pyritään mallintamaan aivojen toimintaa ja suorittamaan tehtäviä, jotka ovat tyypillisesti vaikeita perinteisille tietokoneohjelmille. Neuroverkkoja käytetään esimerkiksi puheentunnistuksessa tai tekoälytoteutuksissa. Tässä diplomityössä tarkastellaan Ta2O5 -perustuvan ReRAM-muistisolun analogista toimintaa pitäen mielessä soveltuvuus neuroverkkoihin. ReRAM-muistisolun valmistus ja mittaustulokset käydään läpi. Muistisolun toiminta on harvoin täysin analogista, koska kahden rajoittavan vastusarvon välillä on usein rajattu määrä tiloja. Tämän vuoksi toimintaa kutsutaan pseudoanalogiseksi. Mittaustulokset osoittavat, että yksittäinen ReRAM-muistisolu kykenee binääriseen toimintaan hyvin. Joiltain osin yksittäinen solu kykenee tallentamaan useampia tiloja, mutta vastusarvoissa on peräkkäisten ohjelmointisyklien välillä suurta vaihtelevuutta, joka hankaloittaa tulkintaa. Valmistettu ReRAM-muistisolu ei sellaisenaan kykene toimimaan pseudoanalogisena muistina, vaan se vaati rinnalleen virtaa rajoittavan komponentin. Myös valmistusprosessin kehittäminen vähentäisi yksittäisen solun toiminnassa esiintyvää varianssia, jolloin sen toiminta muistuttaisi enemmän pseudoanalogista muistia.

Green supply chain management practices and firm performance: evidence from Finland

In order to address the increasing stakeholder requirements for environmentally sustainable products and processes, firms often need the participation of their supply chain partners. Green supply chain management has emerged as a set of managerial practices that integrate environmental issues into supply chain management. If implemented successfully, green supply chain management can be a way to achieve competitive advantage while enhancing the environmental sustainability of the firm. The overall purpose of this dissertation is to contribute to the discussion on green supply chain management practices from the perspective of their drivers and performance implications. The theoretical background arises from the literature on competitive strategy, firm performance and green supply chain management. The research questions are addressed by analysing firm-level data from manufacturing, trading and logistics firms operating in Finland. The empirical data comes from two consecutive Finland State of Logistics surveys in 2012 and 2014, combined with financial reporting data from external databases. The data is analysed with multiple statistical methods. First, the thesis contributes to the discussion of the drivers of GSCM practices. To enhance the understanding of the relationship between competitive strategy and GSCM practices, a conceptual tool to describe generic competitive strategy approaches was developed. The findings suggest that firms pursuing marketing differentiation are more likely to be able to compete by having only small environmental effects and by adopting a more advanced form of external green supply chain management, such as a combination of strong environmental collaboration and the increased environmental monitoring of suppliers. Furthermore, customer requirements for environmental sustainability are found to be an important driver in the implementation of internal GSCM practices. Firms can respond to this customer pressure by passing environmental requirements on to their suppliers, either through environmental collaboration or environmental monitoring. Second, this thesis adds value to the existing literature on the effects of green supply chain management practices on firm performance. The thesis provides support for the idea that there is a positive relationship between GSCM practices and firm performance and enhances the understanding of how different types of GSCM practices are related to 1) financial, 2) operational and 3) environmental performance in manufacturing and logistics. The empirical results suggest that while internal GSCM practices have the strongest effect on environmentalperformance, environmental collaboration with customers seems to be the most effective way to improve financial performance. In terms of operational performance, the findings were more mixed, suggesting that the operational performance of firms is more likely to be affected by firm characteristics than by the choices they make regarding their environmental collaboration. This thesis is also one of the first attempts to empirically analyse the relationship between GSCM practices and performance among logistics service providers. The findings also have managerial relevance. Management, especially in manufacturing and logistics industries, may benefit by gaining knowledge about which types of GSCM practice could provide the largest benefits in terms of different performance dimensions. This thesis also has implications for policy-makers and regulators regarding how to promote environmentally friendly activities among 1) manufacturing; 2) trading; and 3) logistics firms.

Modular continuous crystallizer: operation, experimental arrangement and identification of process parameters

Crystallization is employed in different industrial processes. The method and operation can differ depending on the nature of the substances involved. The aim of this study is to examine the effect of various operating conditions on the crystal properties in a chemical engineering design window with a focus on ultrasound assisted cooling crystallization. Batch to batch variations, minimal manufacturing steps and faster production times are factors which continuous crystallization seeks to resolve. Continuous processes scale-up is considered straightforward compared to batch processes owing to increase of processing time in the specific reactor. In cooling crystallization process, ultrasound can be used to control the crystal properties. Different model compounds were used to define the suitable process parameters for the modular crystallizer using equal operating conditions in each module. A final temperature of 20oC was employed in all experiments while the operating conditions differed. The studied process parameters and configuration of the crystallizer were manipulated to achieve a continuous operation without crystal clogging along the crystallization path. The results from the continuous experiment were compared with the batch crystallization results and analysed using the Malvern Morphologi G3 instrument to determine the crystal morphology and CSD. The modular crystallizer was operated successfully with three different residence times. At optimal process conditions, a longer residence time gives smaller crystals and narrower CSD. Based on the findings, at a constant initial solution concentration, the residence time had clear influence on crystal properties. The equal supersaturation criterion in each module offered better results compared to other cooling profiles. The combination of continuous crystallization and ultrasound has large potential to overcome clogging, obtain reproducible and narrow CSD, specific crystal morphologies and uniform particle sizes, and exclusion of milling stages in comparison to batch processes.

Komposiittipakkausrakenteen valmistustekninen selvitys

Diplomityö on tehty Exel Oyj:lle tuotekehityprojektina. Tarkoituksena on kehittää Exel Oyj:n valmistamaa komposiittipakkausrakennetta. Työssä on keskitytty valmistustekniseen selvitykseen komposiittirakenteen teollisen mittakaavan tuotannossa. Työssä selvitettiin erilaisten tuoterakenteiden valmistettavuutta sekä suoritettiin kyseisen tuotteen vaatimusprofiilin mukaisia testejä valituille rakennevaihtoehdoille. Pakkausrakenteelle asetettuja vaatimuksia ovat mm. kuljetusvaatimukset, jotka määräytyvät lähinnä NATO standardien pohjalta. Lisäksi tuotteelta vaaditaan tiettyä pitkäaikaiskestoa käsittelyn kannalta sekä soveltuvuutta vallitseviin ilmasto-olosuhteisiin. Vaatimusten mukaisia ominaisuuksia tutkittiin lisäksi mm. ballistisilla ja mekaanisilla testeillä sekä kaasuläpäisytesteillä. Testien pohjalta voidaan todeta, etteivät perinteisen alipaineinjektoidun komposiittituotteen ballistiset ominaisuudet ole riittävällä tasolla suojatuotetta ajatellen. Ballististen ja mekaanisten testien kesken havaittiin joitain yhtäläisyyksiä ja tämä vaikuttaa olevan nimenomaan mekaanisesti optimoidun komposiitin ominaisuus. DI-työn lopputuloksena on saatu selkeä kuva pakkausrakenteen materiaalivaihtoehtojen soveltuvuudesta kyseiselle tuotteelle. Lisäksi pakkausrakenteelle on ehdotettu neljä erilaista tuotesuunnitelmaan, niiden valmistustekniikat sekä lopputuotteen kustannusarviointi.

Ohutlevytuotteenvalmistusteknisten piirteiden tunnistaminen ja käyttö suunnittelun apuna

Suunnittelu- ja valmistustoiminnot ovat eriytymässä myös ohutlevyteollisuudessa. Kilpailukyvyn parantamiseksi, valmistusta siirretään alihankkijoille maihin, jossa työvoima on halpaa ja suuret markkinat lähellä, tuotekehityksen ja suunnittelun jäädessä Suomeen tai muualle Länsi-Eurooppaan. Tällöin vanhan lokaalin toimintamallin synergiaedut eivät ole enää mahdollisia ja tuotteen valmistettavuuden arviointi, laadunhallinta ja komponenttien yhteensopivuuden varmistaminen on erittäin haasteellista. Tässä tutkimuksessa etsittiin uuden toimintamallin tuomiin haasteisiin vastauksia piirrepohjaisesta mallintamisesta. Tavoitteen mukaisesti, tutkimuksessa tunnistettiin ohutlevytuotteen valmistusteknilliset piirteet ja luotiin niiden mukainen piirrekaavio. Piirteiden tunnistus vaati tutkimustyötä sekä nykyaikaisten suunnittelumetodien että valmistusmenetelmien ja ohutlevymateriaalien parissa. Lisäksitarkasteltiin, millaisia vaikutuksia piirteillä on tuotteen valmistettavuuteen ja miten nämä tulee huomioida tuotteen suunnittelussa.

Optimoinnin tuloksena tarkasteltavalla yrityksellä on käytössään taloudellinen ja läpimenoajaltaan lyhyt ruiskupuristusmuotin valmistusprosessi.

EU:n uuden kemikaaliasetuksen ja REACH järjestelmän vaikutukset ABB Oy, Sähkökoneisiin

EU on valmistelemassa uutta kemikaaliasetusta joka sisältää myös nk. REACH järjestelmän. Uusi asetus tulee voimaan vuonna2006 tai 2007. Uudella asetuksella pyritään mm. parantamaan ihmisten terveyden ja luonnon suojelua, sekä selventämään nykyään hyvin sekavaa EU:n kemikaalilainsäädäntöä. Kemikaaliasetus koskee kemikaalien valmistusta, maahantuontia ja käyttöä valmistusprosesseissa. Tässä diplomityössä tarkastellaan uuden kemikaaliasetuksen ja REACH järjestelmän aiheuttamia vaikutuksia sähkömoottoreiden ja -generaattoreiden valmistukseen ABB Oy, Sähkökoneiden kannalta. Työssä on tarkasteltu uuden kemikaaliasetuksen tuomia muutoksia kemikaaliturvallisuuden hallintaan ja kemikaalikustannuksiin. Työssä tarkastellaan ABB Oy, Sähkökoneiden roolia jatkokäyttäjänä. Työssä on tarkastellut myös mitä vaikutuksia aineiden mahdollisilla poistumisilla markkinoilta olisi tuotantoprosessiin. Vaikutukset näkyvät pääasiassakemikaalikustannusten nousuna ja muutoksina kemikaali turvallisuuden hallinnassa, lisäksi markkinoilta saattaa poistua valmistuksen kannalta tärkeitä kemikaaleja. Asetuksen voimaantulon aiheuttamien lopullisten kustannusten määrään vaikuttaa suuresti se kuinka paljon aineita poistuu markkinoilta ja kuinka paljon tämän takia joudutaan tekemään muutoksia valmistusprosessissa.

Aktiivihiilessä etenevän adsorptiorintaman mittaaminen puolijohdekaasuantureiden avulla

Tässä diplomityössä tutkitaan aktiivihiilielementissä etenevän kaasun adsorptiorintaman mittaamista puolijohdekaasuantureiden avulla. Työn teoriaosuudessa on tutustuttu aktiivihiilen suodattaviin ominaisuuksiin, valmistusprosessiin ja aktiivihiilen raaka-aineen valintaan. Teoreettisen tarkastelun perusteella työssä on laboratorio-olosuhteissa tutkittu lämmitettävien puolijohdekaasuanturien soveltuvuutta hiilessä etenevän adsorptiorintaman havaitsemiseen. Puolijohdekaasuantureille suoritetun herkkyystestauksen perusteella tutkittiin antureiden kykyä tunnistaa aktiivihiileen adsorboituneiden aineiden eteneminen hiilimateriaalissa. Suoritettujen mittausten perusteella todettiin puolijohdeantureiden soveltuvan hyvin aktiivihiilessä etenevän adsorptiorintaman havaitsemiseen. Antureiden selektiivisyydestä johtuen tutkittaessa useamman kaasun muodostaman adsorptiorintaman etenemistä hiilessä on käytettävä useita erityyppisiä puolijohdekaasuantureita.
