Tietojärjestelmän käyttöönotto ja ylläpito

Tässä kandidaatintyössä tarkastellaan tietojärjestelmän käyttöönottoa ja ylläpitoa yleisesti sekä käyttöönottoa pilvipalveluna. Tietojärjestelmien käyttöönotto ja ylläpito ovat perinteisten elinkaarimallien viimeisiä vaiheita. Erityisesti järjestelmän käyttöönotto on hyvin kriittinen vaihe koko tietojärjestelmäprojektin onnistumisen kannalta. Käyttöönottoprosessi on monivaiheinen ja sisältää monia haasteita. Käyttöönottoon osallistuvien tahojen tulee sopia roolit etukäteen, jotta prosessi voi onnistua. Tietojärjestelmien ylläpidolla ajatellaan perinteisesti esille tulleiden virheiden korjaamista. Siihen kuuluu kuitenkin muitakin toimia, kuten järjestelmän kehittämistä, sopeuttamista ja ennalta ehkäiseviä toimenpiteitä. Ylläpito vie usein suuren osan koko järjestelmän budjetista, joten se tulee hoitaa järkevästi ja suunnitellusti. Työssä tutkitaan tietojärjestelmän käyttöönottoa pilvipalveluna käymällä lävitse pilvipalvelun käyttöönoton elinkaari sekä myös ERP -järjestelmän käyttöönottoprosessin eri vaiheet pilvipalveluna. Käyttöönoton elinkaaren ja käyttöönottoprosessin pohjalta havaitaan, että tietojärjestelmän käyttöönotto helpottuu ja nopeutuu pilvipalveluna, mutta käyttöönottoprosessi vaatii kuitenkin huolellista suunnittelua. Työssä perehdytään käyttöönoton yhteydessä tehtävään palvelutasosopimukseen ja siinä käsiteltäviin asioihin. Lisäksi sivutaan pilvipalveluiden käyttöönotossa huomioitavina asioina myös tietoturvallisuutta, tietosuojan lainsäädäntöä sekä vanhojen sovellusten toimivuutta pilviympäristössä.

Pilvipalvelut ja niiden käyttö yrityksissä

Tässä kandidaatintyössä tutkitaan pilvipalveluita sekä niiden käyttöä yrityksissä. Työn tavoitteena on antaa lukijalle käsitys siitä, mitä käsite pilvipalvelut pitää sisällään. Lisäksi työssä pyritään kuvaamaan siitä, milloin yrityksen olisi kannattavaa siirtyä nykyisestä toimintamallistaan käyttämään pilvipalveluita. Pilvipalveluista tarkastellaan niiden rakennetta, kehityshistoriaa, ominaisuuksia sekä keskeisimpiä palveluita ja palveluntarjoajia. Pilvipalveluiden käyttämisestä yrityksissä pohditaan yritysten soveltuvuutta pilvipalveluiden käyttäjiksi sekä käytöstä johtuvia muutoksia kustannuksiin ja toimintaan. Pilvipalveluiden suosio tulee todennäköisesti kasvamaan ja uudenlaisten palvelujen määrä lisääntyy. Yritykset tulevat käyttämään enemmän pilvipalveluita niiden tuomien hyötyjen vuoksi. Kuitenkin monia ongelmia, esimerkiksi tietoturvan saralla, tulee ratkaista ennen kuin pilvipalvelut saavuttavat suuremman suosion.

Optimizing Customer Energy Invoice Calculation with Parallel Computation

Diplomityön tarkoituksena on optimoida asiakkaiden sähkölaskun laskeminen hajautetun laskennan avulla. Älykkäiden etäluettavien energiamittareiden tullessa jokaiseen kotitalouteen, energiayhtiöt velvoitetaan laskemaan asiakkaiden sähkölaskut tuntiperusteiseen mittaustietoon perustuen. Kasvava tiedonmäärä lisää myös tarvittavien laskutehtävien määrää. Työssä arvioidaan vaihtoehtoja hajautetun laskennan toteuttamiseksi ja luodaan tarkempi katsaus pilvilaskennan mahdollisuuksiin. Lisäksi ajettiin simulaatioita, joiden avulla arvioitiin rinnakkaislaskennan ja peräkkäislaskennan eroja. Sähkölaskujen oikeinlaskemisen tueksi kehitettiin mittauspuu-algoritmi.

ERP-järjestelmät pilvipalveluna

Työssä tutkitaan ERP-järjestelmää pilvipalveluna. Tutkimusmenetelmänä on käytetty kirjallisuuskatsausta. Työn tavoitteena on antaa lukijalle kuva siitä, mitä käsitteellä ERP-pilvipalveluna tarkoitetaan, miten se eroaa perinteisestä ERP–järjestelmästä sekä analysoida hyötyjä ja haittoja molemmissa ratkaisuissa. ERP-pilvipalvelulla tarkoitetaan ostettua palvelua, jota hallinnoi ja ylläpitää ulkopuolinen yritys. Järjestelmän käytöstä maksetaan kiinteä kuukausittainen maksu ja käyttäjämääriin perustuva maksu. Yrityksen käyttäessä ERP-pilvipalvelua sen ei tarvitse investoida laitteisiin. ERP-pilvipalvelu voi olla toteutettuna yritykselle varatussa yksityisessä pilvessä tai julkisessa pilvessä. Pilvipalveluna toteutettu ERP tekee kustannusten arvioinnin helpommaksi lyhyellä aikavälillä sen maksurakenteen takia. Pieni alkuinvestointi kannustaa ERP-pilvipalvelun käyttöön varsinkin pienissä yrityksissä. Isot yritykset kuitenkin suosivat perinteisiä ERP–ratkaisuja niiden paremman muokattavuuden takia. Suurin osa ERP–järjestelmistä on perinteisiä ratkaisuja. Yritykset pitävät pilvipalveluna toteutetun ERP:n suurimpana haasteena tietoturvariskejä. ERP-pilvipalvelu tekee yrityksen enemmän riippuvaiseksi palveluntarjoajasta.

Virtual technology and haptic interface solutions for design and control of mobile working machines

Commercially available haptic interfaces are usable for many purposes. However, as generic devices they are not the most suitable for the control of heavy duty mobile working machines like mining machines, container handling equipment and excavators. Alternative mechanical constructions for a haptic controller are presented and analysed. A virtual reality environment (VRE) was built to test the proposed haptic controller mechanisms. Verification of an electric motor emulating a hydraulic pump in the electro-hydraulic system of a mobile working machine is carried out. A real-time simulator using multi-body-dynamics based software with hardware-in-loop (HIL) setup was used for the tests. Recommendations for further development of a haptic controller and emulator electric motor are given.

Control of Robot by Means of Human Thought

Brain computer interface (BCI) is a kind of human machine interface, which provides a new interaction method between human and computer or other equipment. The most significant characteristic of BCI system is that its control input is brain electrical activities acquired from the brain instead of traditional input such as hands or eyes. BCI technique has rapidly developed during last two decades and it has mainly worked as an auxiliary technique to help the disable people improve their life qualities. With the appearance of low cost novel electrical devices such as EMOTIV, BCI technique has been applied to the general public through many useful applications including video gaming, virtual reality and virtual keyboard. The purpose of this research is to be familiar with EMOTIV EPOC system and make use of it to build an EEG based BCI system for controlling an industrial manipulator by means of human thought. To build a BCI system, an acquisition program based on EMOTIV EPOC system is designed and a MFC based dialog that works as an operation panel is presented. Furthermore, the inverse kinematics of RV-3SB industrial robot was solved. In the last part of this research, the designed BCI system with human thought input is examined and the results indicate that the system is running smoothly and displays clearly the motion type and the incremental displacement of the motion.

Software business expansion through distribution channel : Case M-Files - Denmark

The purpose of this study was to find out how a software company can successfully expand business to the Danish software market through distribution channel. The study was commissioned by a Finnish software company and it was conducted using a qualitative research method by analyzing external and internal business environment, and interviewing Danish ICT organizations and M-Files personnel. Interviews were semi-structured interviews, which were designed to collect comprehensive information on the existing ICT and software market in Denmark. The research used three external and internal analyzing frameworks; PEST analysis (market level), Porter´s Five Force analysis (industry level competition) and SWOT analysis (company level). Distribution channels theory was a base to understand why and what kind of distribution channels the case company uses, and what kind of channels target markets companies’ uses. Channel strategy and design were integrated to the industry level analysis. The empirical findings revealed that Denmark has very business friendly ICT environment. Several organizations have ranked Denmark´s information and communication technology as the best in the world. Denmark’s ICT and software market are relatively small, compared to many other countries in Europe. Danish software market is centralized. Largest software clusters are in the largest cities; Copenhagen, Aarhus, Odense and Aalborg. From these clusters, software companies can most likely find suitable resellers. The following growing trends are clearly seen in the software market: mobile and wireless applications, outsourcing, security solutions, cloud computing, social business solutions and e-business solutions. When expanding software business to the Danish market, it is important to take into account these trends. In Denmark distribution channels varies depending on the product or service. For many, a natural distribution channel is a local partner or internet. In the public sector solutions are purchased through a public procurement process. In the private sector the buying process is more straight forwarded. Danish companies are buying software from reliable suppliers. This means that they usually buy software direct from big software vendors or local partners. Some customers prefer to use professional consulting companies. These consulting companies can strongly influence on the selection of the supplier and products, and in this light, consulting companies can be important partners for software companies. Even though the competition is fierce in ECM and DMS solutions, Danish market offers opportunities for foreign companies. Penetration to the Danish market through reseller channel requires advanced solutions and objective selection criteria for channel partners. Based on the findings, Danish companies are interested in advanced and efficient software solutions. Interest towards M-Files solutions was clearly seen and the company has excellent opportunity to expand business to the Danish market through reseller channel. Since the research explored the Danish ICT and software market, the results of the study may offer valuable information also to the other software companies which are expanding their business to the Danish market.

El pensamiento sublime en 3D. Proyecto experimental de Instalación Museográfica Virtual

Entre los años 2005 y 2006, se realizaron en Madrid dos interesantes encuentros internacionales denominados Tecnologías para una Museografía Avanzada, promovidos por el Consejo Internacional de Museos (ICOM), donde representantes de diversas instituciones culturales explicaban las influencias enriquecedoras que han aportado a sus exposiciones los nuevos medios tecnológicos en conjunto con la didáctica y la Museografía Interactiva como elementos mediadores de discurso. Representantes y Directores de instituciones como el Museo de Historia de Valencia (MHV), el Museo Arqueológico Provincial de Alicante (MARQ) o el Museo de la Cultura Bizantina de Grecia por ejemplo, han presentado las propuestas que en este contexto les ha permitido comunicar ideas refrescantes y nuevas estrategias para la compresión de diversos tipos de patrimonios. La premisa expuesta por ellos enfatizaba el pensamiento de que las nuevas tecnologías aunadas a la Museografía Interactiva, constituyen un apoyo didáctico a la hora de transmitir significados provenientes de los objetos patrimoniales para desarrollar y ampliar la comprensión del visitante en relación a los contenidos de las exposiciones. A este respecto, llama la atención la ausencia de museos especializados en Arte ante este tipo de discursos innovadores que suelen provocar en los visitantes soluciones educativas in situ, otorgando nuevos enfoques de las cosas, de la historia, de los objetos y de las generaciones pasadas.
