The masters thesis focused on implementing a sales and operations planning process. The main objectives were to create planning methods and tools for the implementation. The ultimate goal of the process, beyond this masters thesis, is to balance the supply of products with customer demand, with optimized profitability. The theoretical part focused on giving a thorough view on the sales and operations planning process. The basis for a monthly planning cycle was identified. Methods, tools, and metrics for demand forecasting and operations planning were also introduced. Based on the theoretical part, a method for forecasting, a forecast spreadsheet, and a forecast accuracy metric were designed. A spreadsheet tool and methods were also designed for the monthly planning of production volumes, capacity, and inventory. The implementation progress was reviewed for two product families for three months. The sales and operations planning process was able to successfully identify a demand peak for the product families. Suggestions for the future of sales and operations planning were also made.

The effects of pulp processing on softwood fiber properties strongly influence the properties of wet and dry paper webs. Pulp strength delivery studies have provided observations that much of the strength potential of long fibered pulp is lost during brown stock fiber line operations where the pulp is merely washed and transferred to the subsequent processing stages. The objective of this work was to study the intrinsic mechanisms which maycause fiber damage in the different unit operations of modern softwood brown stock processing. The work was conducted by studying the effects of industrial machinery on pulp properties with some actions of unit operations simulated in laboratory scale devices under controlled conditions. An optical imaging system was created and used to study the orientation of fibers in the internal flows during pulp fluidization in mixers and the passage of fibers through the screen openings during screening. The qualitative changes in fibers were evaluated with existing and standardized techniques. The results showed that each process stage has its characteristic effects on fiber properties: Pulp washing and mat formation in displacement washers introduced fiber deformations especially if the fibers entering the stage were intact, but it did not decrease the pulp strength properties. However, storage chests and pulp transfer after displacement washers contributed to strength deterioration. Pulp screening proved to be quite gentle, having the potential of slightly evening out fiber deformations from very deformed pulps and vice versa inflicting a marginal increase in the deformation indices if the fibers were previously intact. Pulp mixing in fluidizing industrial mixers did not have detrimental effects on pulp strength and had the potential of slightly evening out the deformations, provided that the intensity of fluidization was high enough to allow fiber orientation with the flow and that the time of mixing was short. The chemical and mechanical actions of oxygen delignification had two distinct effects on pulp properties: chemical treatment clearly reduced pulp strength with and without mechanical treatment, and the mechanical actions of process machinery introduced more conformability to pulp fibers, but did not clearly contribute to a further decrease in pulp strength. The chemical composition of fibers entering the oxygen stage was also found to affect the susceptibility of fibers to damage during oxygen delignification. Fibers with the smallest content of xylan were found to be more prone to irreversibledeformations accompanied with a lower tensile strength of the pulp. Fibers poor in glucomannan exhibited a lower fiber strength while wet after oxygen delignification as compared to the reference pulp. Pulps with the smallest lignin content on the other hand exhibited improved strength properties as compared to the references.

IT outsourcing refers to the way companies focus on their core competencies and buy the supporting functions from other companies specialized in that area. Service is the total outcome of numerous of activities by employees and other resources to provide solutions to customers' problems. Outsourcing and service business have their unique characteristics. Service Level Agreements quantify the minimum acceptable service to the user. The service quality has to be objectively quantified so that its achievement or non-achievement of it can be monitored. Usually offshoring refers to the transferring of tasks to low-cost nations. Offshoring presents a lot of challenges that require special attention and they need to be assessed thoroughly. IT Infrastructure management refers to installation and basic usability assistance of operating systems, network and server tools and utilities. ITIL defines the industry best practices for organizing IT processes. This thesis did an analysis of server operations service and the customers perception of the quality of daily operations. The agreed workflows and processes should be followed better. Service providers processes are thoroughly defined but both the customer and the service provider might disobey them. Service provider should review the workflows regarding customer functions. Customer facing functions require persistent skill development, as they communicate the quality to the customer. Service provider needs to provide better organized communication and knowledge exchange methods between the specialists in different geographical locations.

Tutkielmassa eritelln Norman Faircloughin kriittisen diskurssianalyysin teoriaa ja siihen kohdistettua kritiikki. Pyrkimyksen on sovittaa nit erilaisia nkemyksi keskenn ja tarjota ratkaisuja yhteen kiriittisen diskurssianalyysin keskeiseen ongelmaan eli emansipaation (sosiaalisten epkohtien tunnistamisen ja ratkaisemisen) puutteellisuuteen. Teoriaosuudesta esiin nousevia mahdollisuuksia sovelletaan tekstianalyysiin. Tutkimuksen kohteena on teksti Rebuilding Americas Defenses: Strategy, Forces and Resources For a New Century ja jossain mrin sen tuottanut jrjest Project for the New American Century. Nit tarkastellaan ennen kaikkea sosiaalisina ilmiin ja suhteessa toisiinsa. Faircloughin mallin suurimmiksi ongelmiksi muodostuvat perinteinen ksitys kielest, jonka mukaan kielen jrjestelmn abstraktit ja sisiset suhteet ovat trkeimpi, sek ideologinen vastakkainasettelu kritiikin lhtkohtana. Ensimminen johtaa kielellisten tutkimustulosten eptyydyttvn kykyyn selitt sosiaalisia havaintoja ja jlkimminen poliittiseen tai maailmankatsomukselliseen vittelyyn, joka ei mahdollista uusia nkemyksi. Tutkielman lopputulema on, ett keskittymll asiasisltn kielen rakenteen sijasta ja ymmrtmll tekstin tuottaja yksittisen, rajattuna sosiaalisena toimijana voidaan analyysiin saada avoimuutta ja tsmllisyytt. Kriittiinen diskurssianalyysi kaipaa tllaista nkemyst kielellisten analyysien tueksi ja uudenlaisen relevanssin lytkseen.

The research of virtual professional networks has been enormous but the lack of research in the dental field was obvious. This study focuses on those uses and gratifications, and motives of participants that a virtual pro-fessional network should fulfil. The aim of this study is to understand the factors behind the successful virtual professional network, and motives of participants that support a particular business networks building up for contributing its further success. In this study the focus is on particular mo-tives, needs and benefits of participants that are significant for the net-works further development. The study will explore relevant scientific research and theory that is char-acteristic in networking, and theories of users needs and motives. Empiri-cal data was collected from dental professionals by net based question-naire that was sent by e-mail. Data analysis was done by quantitative fac-tor analysis. The findings of this study were obvious that virtual knowledge of implantology is inadequate and knowledge is rather difficult to find in the Internet. Sharing of virtual knowledge, net-learning and communication were seen to improve the quality of impolantological professionalism and also the development of these areas was experienced essential. On the grounds of this study a host of a virtual professional network can focus on those aspects that serve the users at best, can develop professionalism in implantology and can profit in its own business operations.

Les 21, 22 et 23 septembre 2006, le Dpartement dtudes Franaises de lUniversit de Turku (Finlande) a organis une confrence internationale et bilingue (anglais et franais) sur le thme de la mobilit acadmique ; le but de cette rencontre tait de rendre possible la tenue dun forum international et multidisciplinaire, susceptible dtre le sige de divers dbats entre les diffrents acteurs de la mobilit acadmique (cestdire des tudiants, des chercheurs, des personnels enseignants et administratifs, etc.). Ainsi, ont t mis contribution plus de cinquante intervenants, (tous issus de domaines aussi varis que la linguistique, les sciences de lducation, la didactique, lanthropologie, la sociologie, la psychologie, lhistoire, la gographie, etc.) ainsi que cinq intervenants renomms1. La plupart des thmes traits durant la confrence couvraient les champs suivants : lorganisation de la mobilit, les obstacles rencontrs par les candidats la mobilit, lintgration des tudiants en situation dchange, le dveloppement des programmes dtudes, la mobilit virtuelle, lapprentissage et lenseignement des langues, la prise de cosncience interculturelle, le dveloppement des comptences, la perception du systme de mobilit acadmique et ses impacts sur la mobilit effective. Lintrt du travail ralis durant la confrence rside notamment dans le fait quil ne concentre pas uniquement des perspectives dtudiants internationaux et en situation dchange (comme cest le cas de la plupart des travaux de recherche dj mens sur ce sujet), mais aussi ceux dautres corps : enseignants, chercheurs, etc. La contribution suivante contient un premier corpus de dixsept articles, rpartis en trois sections : 1. Impacts de la mobilit tudiante ; 2. Formation en langues ; 3. Amlioration de la mobilit acadmique. limage de la confrence, la production qui suit est bilingue : huit des articles sont rdigs en franais, et les neuf autres en anglais. Certains auteurs nont pas pu assister la confrence mais ont tout de mme souhait apparatre dans cet ouvrage. Dans la premire section de louvrage, Sandrine Billaud tche de mettre jour les principaux obstacles la mobilit tudiante en France (logement, organisation des universits, dmarches administratives), et propose ce sujet quelques pistes damlioration. Vient ensuite un article de Dominique Ulma, laquelle se penche sur la mobilit acadmique rgnant au sein des Instituts Universitaires de Formation des Matres (IUFM) ; elle sest tout particulirement concentre sur lenthousiasme des stagiaires visvis de la mobilit, et sur les bnfices quapporte la mobilit Erasmus ce type prcis dtudiant. Ensuite, dans un troisime article, Magali Hardoin sinterroge sur les potentialits ducationnelles de la mobilit des enseignantsstagiaires, et tche de dfinir limpact de celleci sur la construction de leur profil professionnel. Aprs cela arrive un groupe de trois articles, tous raliss bases dobservations faites dans lenseignement suprieur espagnol, et qui traitent respectivement de la porte qua le programme de triple formation en langues europennes appliques pour les tudiants en mobilit (Marin MornMartn), des consquences quoccasionne la prsence dtudiants trangers dans les classes de traductions (Dimitra Tsokaktsidu), et des ralits de lintgration sur un campus espagnol dtudiants amricains en situation dchange (Guadalupe Soriano Barabino). Le dernier article de la section, issu dune tude sur la situation dans les institutions japonaises, fait tat de la situation des programmes de doubles diplmes existant entre des tablissements japonais et trangers, et tente de voir quel est limpact exact de tels programmes pour les institutions japonaises (Mihoko Teshigawara, Riichi Murakami and Yoneo Yano). La seconde section est elle consacre la relation entre apprentissage et enseignement des langues et mobilit acadmique. Dans un premier article, Martine Eisenbeis sintresse des modules multimdia raliss base du film Lauberge espagnole , de Cdric Klapish (2001), et destins aux tudiants en mobilit dsireux dapprendre et/ou amliorer leur franais par des mthodes moins classiques. Viennent ensuite les articles de Jeanine Gerbault et Sabine Ylnen, lesquels traitent dun projet europen visant supporter la mobilit tudiante par la cration dun programme multimdia de formation linguistique et culturelle pour les tudiants en situation de mobilit (le nom du projet est EUROMOBIL). Ensuite, un article de Pascal Schaller sintresse aux diffrents types dactivits que les tudiants en sjour ltranger exprimentent dans le cadre de leur formation en langue. Enfin, la section sachve avec une contribution de Patricia KohlerBally, consacre un programme bilingue coordonn par lUniversit de Fribourg (Suisse). La troisime et dernire section propose quelques pistes de rflexion destines amliorer la mobilit acadmique des tudiants et des enseignants ; dans ce cadre seront donc voques les questions de lgalit face la mobilit tudiante, de la prparation ncessite par celleci, et de la prise de conscience interculturelle.

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.

Supply chain risk management has emerged as an increasingly important issue in logistics as disruptions in the supply chain have become critical issues for many companies. The scientific literature on the subject is developing and in many respects the understanding of it is still in its infancy. Thus, there is a need for more information in order for scholars and practitioners to understand the causalities and interrelations that characterise the phenomenon. The aim of this dissertation is to narrow this gap by exploring key aspects of supply chain risk management through two maritime supply chains in the immediate region of the Gulf of Finland. The study contributes to the field in three different ways. Firstly, it facilitates the identification of risks on different levels of the supply chain through a systematic analysis of the processes and actors, and of the cognitive barriers that limit the actors visibility and their understanding of the operations and the risks involved. There is a clear need to increase collaboration and information exchange in order to improve visibility in the chain. Risk management should be a collaborative effort among the individual actors, aimed at obtaining a holistic picture. Secondly, the study contributes to the literature on risk analysis through the use of systemic frameworks that illustrate the causalities and linkages in the system, thereby making it easier to perceive the vulnerabilities. Thirdly, the study enhances current knowledge of risk control in identifying actor roles, risk visibility and risk controllability as being among the key factors determining risk-management effectiveness against supply-chain vulnerability. This dissertation is divided into two parts. The first part gives a general overview of the relevant literature, the research design and the conclusions of the study, and the second part comprises six research publications. Case-study methodology with systematic combining approach is used, where in-depth interviews, questionnaires and expert panel sessions are the main data collection methods. The study illustrates the current state of risk management in multimodal maritime supply chains, and develops frameworks for further analysis. The results imply that there are major differences between organizations in their ability to execute supply chain risk management. Further collaboration should be considered in order to facilitate the development of systematic and effective management processes.
