Product management in global sales operations

Työn tavoitteena oli määrittää myyntikonfiguraattorissa käytettävän tuotemallin yleinen rakenne. Ensin selvitettiin tuotemallin luomista ja konseptin suunnittelua kirjallisuuden ja asiantuntijoiden haastattelujen avulla. Asiantuntijoiden haastattelut toteutettiin vapaamuotoisesti kysymyslistaa apuna käyttäen. Tämän lisäksi työssä pohditaan sähköisen liiketoiminnan roolia sekä myyntikonfiguraattorin tulevaisuuden näkymiä. Diplomityössä käsitellään tuotemallia yleisellä tasolla. Toinen näkökulma käsittelee tuotemallia tietoteknisissä sovelluksissa käytettyjen menetelmien pohjalta. Tuotemallin muodostaminen aloitettiin asiakkaalle näkyvästä osasta eli myyntikonfiguraattorin ulkoasusta. Seuraava ongelma oli standardoida tuotetta ja tarjousta kuvaavat dokumentit globaalisti. Tähän ratkaisuun päädyttiin haastattelujen sekä asiantuntijoiden kokoontumisien pohjalta. Loppuosa diplomityöstä käsittelee myyntikonfiguraattorin asemaa kohdeyrityksen sähköisessä liiketoiminnassa sekä esittelee erään näkemyksen myyntikonfiguraattorin yhteenliittymästä asiakashallinta- ja tuotetiedonhallinta järjestelmiin. Diplomityössä saavutettiin asetetut tavoiteet: Myyntikonfigurattori yhtenäistää kohdeyrityksen hinnoittelua globaalisti, nopeuttaa tarjouksentekoprosessia, helpottaa uuden tuotteen lanseerausta ja standardoi tuotemallin globaalisti. Myyntikonfiguraattorin integrointi muihin tietojärjestelmiin tehostaa myynnin toimintoja. Haasteeksi jää loppukäyttäjien kannustaminen tehokkaaseen käyttöön sekä ylläpidon toteuttaminen. Ilman käyttäjiä ja heidän innostustaan voi projekti menettää johdon luottamuksen.

Customer relationship management and central bank payment system services

Tutkimuksen tavoitteena on selvittää, miten kirjallisuudessa kuvattua asiakkuuden hallintaa voitaisiin soveltaa keskuspankin maksuliikepalveluissa. Tarkasteltavana ovat yleiset toimintatavat, sekä asiakkuuden hallintaa tukevat järjestelmät. Tutkimuksen päätavoitteena on Help Desk toiminnan kehittäminen. Tutkimuksessa tarkastellaan asiakkuuden hallinnan eri osa-alueita ottaen huomioon sekä asiakkaan, että palvelun tarjoajan näkökulmat. Asiakkuuden hallinta ymmärretään strategiana, jolla kyetään kuvaamaan kuinka koko organisaatio toimii asiakkaiden kanssa. Asiakkuuden hallinnan ydin on asiakkaan arvontuotantoprosessin ymmärtäminen. Käytettyjä lähdeaineistoja ovat olleet alan kirjallisuus, artikkelit sekä Internet-lähteet. Empirian taustan ovat muodostaneet asiantuntijahaastattelut sekä keskuspankin julkaisut, sisäiset toimintaohjeet ja vakiintuneet käytännöt. Tutkimuksen keskeinen tulos on, että asiakkuudenhallinnan perusajatukset ovat monin tavoin sovellettavissa keskuspankin melko ainutkertaiseen, teknisesti ja viestinnällisesti vaativaan maksuliikepalveluympäristöön, vaikka asiakkaiden lukumäärä onkin pieni. Hyötyjä voidaan saavuttaa jo asiakkuudenhallinnan peruskomponenttien ml. strategianäkökulma tuntemuksella ja melko pieniltäkin näyttävillä toimintatapa-, työnkulku- ja asennemuutoksilla. Asiakkuuden hallintaa tukevan tietoteknologian jonkinasteinen käyttöönotto voi tuoda lisäarvoa, mutta sen kustannukset ja hyödyt on punnittava tämäntyyppisessä ympäristössä tarkoin.

Työpisteiden tiedonkäyttö ja hyödyntäminen osana palveluyhtiön johtamisjärjestelmää

Tutkimuksen tavoitteena oli etsiä kohdeorganisaation taustalla olevia tekijöitä, jotka joko edesauttavat tai estävät nykyisen johtamisjärjestelmän soveltamista, tiedon käyttöä ja hyödyntämistä organisaation työpisteissä. Kohdeorganisaatio on Varenso Oy, Tekniset tuotantopalvelut. Teoriaosiossa käsitellään tietojohtamiseen liittyvää käsitteistöä sekä tiedon luomiseen, johtamiseen ja hyödyntämiseen liittyviä tekijöitä. Johtamista lähestytään myös perustehtävän, strategian ja muutosvalmiuden, valta- ja organisaatiorakenteiden sekä informaatio- ohjauksen näkökulmasta. Lopuksi käsitellään suorituskykyä, tavoitteiden asettamista, mittaamista funktionaalisissa- ja prosessijohdetuissa organisaatioissa. Empiirisessä osiossa tehtiin kyselytutkimus. Tulokset analysoitiin monimuuttujamenetelmiä soveltaen ja löydettiin faktorit, joiden avulla on mahdollista vaikuttaa kohdeorganisaation toimintaan. Kyselytutkimuksen avulla tulkittiin organisaation tämän hetkistä suorituskykyä ja asemaa suhteessa tavoitteisiin. Tuloksena syntyi myös toimenpideehdotuksia.

Long-term X-ray variability of the microquasar system LS5039/RX J1826.2-1450

We report on the results of the spectral and timing analysis of a BeppoSAX observation of the microquasar system LS 5039/RX J1826.2-1450. The source was found in a low-flux state with Fx(1-10 keV)= 4.7 x 10^{-12} erg cm^{-2} s^{-1}, which represents almost one order of magnitude lower than a previous RXTE observation 2.5 years before. The 0.1--10 keV spectrum is described by an absorbed power-law continuum with photon-number spectral index Gamma=1.8+-0.2 and hydrogen column density of NH=1.0^{+0.4}_{-0.3} x 10^{22} cm^{-2}. According to the orbital parameters of the system the BeppoSAX observation covers the time of an X-ray eclipse should one occur. However, the 1.6-10 keV light curve does not show evidence for such an event, which allows us to give an upper limit to the inclination of the system. The low X-ray flux detected during this observation is interpreted as a decrease in the mass accretion rate onto the compact object due to a decrease in the mass-loss rate from the primary.

A System-Level Simulation Model for a Protocol Processor

As the development of integrated circuit technology continues to follow Moore’s law the complexity of circuits increases exponentially. Traditional hardware description languages such as VHDL and Verilog are no longer powerful enough to cope with this level of complexity and do not provide facilities for hardware/software codesign. Languages such as SystemC are intended to solve these problems by combining the powerful expression of high level programming languages and hardware oriented facilities of hardware description languages. To fully replace older languages in the desing flow of digital systems SystemC should also be synthesizable. The devices required by modern high speed networks often share the same tight constraints for e.g. size, power consumption and price with embedded systems but have also very demanding real time and quality of service requirements that are difficult to satisfy with general purpose processors. Dedicated hardware blocks of an application specific instruction set processor are one way to combine fast processing speed, energy efficiency, flexibility and relatively low time-to-market. Common features can be identified in the network processing domain making it possible to develop specialized but configurable processor architectures. One such architecture is the TACO which is based on transport triggered architecture. The architecture offers a high degree of parallelism and modularity and greatly simplified instruction decoding. For this M.Sc.(Tech) thesis, a simulation environment for the TACO architecture was developed with SystemC 2.2 using an old version written with SystemC 1.0 as a starting point. The environment enables rapid design space exploration by providing facilities for hw/sw codesign and simulation and an extendable library of automatically configured reusable hardware blocks. Other topics that are covered are the differences between SystemC 1.0 and 2.2 from the viewpoint of hardware modeling, and compilation of a SystemC model into synthesizable VHDL with Celoxica Agility SystemC Compiler. A simulation model for a processor for TCP/IP packet validation was designed and tested as a test case for the environment.

State of Logistics and Operations Management in Finnish and Swedish Companies – Survey Research Findings

In this research we are examining what is the status of logistics and operations management in Finnish and Swedish companies. Empirical data is based on the web based questionnaire, which was completed in the end of 2007 and early 2008. Our examination consists of roughly 30 answers from largest manufacturing (highest representation in our sample), trade and logistics/distribution companies. Generally it could be argued that these companies operate in complex environment, where number of products, raw materials/components and suppliers is high. However, usually companies rely on small amount of suppliers per raw material/component (highest frequency is 2), and this was especially the case among Swedish companies, and among those companies, which favoured overseas sourcing. Sample consisted of companies which mostly are operating in an international environment, and are quite often multinationals. Our survey findings reveal that companies in general have taken logistics and information technology as part of their strategy process; utilization of performance measures as well as system implementations have followed the strategy decisions. In the transportation mode side we identify that road transports dominate all transport flow classes (inbound, internal and outbound), followed by sea and air. Surprisingly small amount of companies use railways, but in general we could argue that Swedish companies prefer this mode over Finnish counterparts. With respect of operations outsourcing, we found that more traditional areas of logistics outsourcing are driving factors in company's performance measurement priority. In contrary to previous research, our results indicate that the scope of outsourcing is not that wide in logistics/operations management area, and companies are not planning to outsource more in the near future. Some support is found for more international operations and increased outsourcing activity. From the increased time pressure of companies, we find evidence that local as well as overseas customers expect deliveries within days or weeks, but suppliers usually supply within weeks or months. So, basically this leads into considerable inventory holding. Interestingly local and overseas sourcing strategy does not have that great influence on lead time performance of these particular sourcing areas - local strategy is anyway considerably better in responding on market changes due to shorter supply lead times. In the end of our research work we have completed correlation analysis concerning items asked with Likert scale. Our analysis shows that seeing logistics more like a process rather than function, applying time based management, favouring partnerships and measuring logistics within different performance dimensions results on preferred features and performance found in logistics literature.

Modernization of protection and control system of HV/MV substation in Russia

This work describes different possibilities of protection and control system improvement of primary distribution substation. The status of condition and main problems of power networks from reliability point of view in Russia are described. This work studies technologies used today in Russia for protection of distribution networks with their disadvantages. Majority of medium voltage networks (6-35 kV) has isolated network point. There is still no any protection available on the market which allows to estimate distance to fault in case of earth fault. The thesis analyses methods of earth fault distance calculation. On the basis of computer simulation the influence of various factors on calculation accuracy is studied. The practical implementation of the method presupposes usage of digital relay. Application of digital relay is accompanied by numerous opportunities which are described in this work. Also advantages of system implemented on the basis of IEC 61850 standard are examined. Finally, suitability of modern digital relays from GOST standard point of view is analyzed.

Supplier Energy Audits in Thermal Power Plants

This master’s thesis handles an operating model for an electric equipment supplier conducted sale oriented energy audit for pumping, fan and other motor applications at power plants. The study goes through the largest factors affecting internal electricity use at a power plant, finds an energy audit –like approach for the basis of information gathering and presents the information needed for conducting the analysis. The model is tested in practice at a kraft recovery boiler of a chemical pulping mill. Targets chosen represent some of the largest electric motor applications in the boiler itself and in its fuel handling. The energy saving potential of the chosen targets is calculated by simulating the energy consumption of the alternatives for controlling the targets, and thereafter combining the information with the volume flow duration curve. Results of the research are somewhat divaricated, as all the information needed is not available in the automation system. Some of the targets could be simulated and their energy saving potential calculated quite easily. At some of the targets chosen the monitoring was not sufficient enough for this and additional measurements would have been needed to base the calculations on. In traditional energy audits, energy efficiency of pump and fan applications is not necessarily examined. This means that there are good possibilities for developing the now presented targeted energy audit procedure basis further.

Dial M for Murder: A Case of Passion Killing, Criminal Evidence and Sultanic Power in Medieval India

This paper considers the structures and applications of the criminal judicial system in the Islamic Later Middle Period as it developed in India under the sultans of Delhi (1200-1400 CE). A fundamental issue in crime and punishment is the relationship between sultanic power and religious authority. Particularly at stake in this relationship is the question of who can sanction the highest form of punishment, i.e. the death penalty (siyāsa). Contemporary historians and scholars in the study of religion investigating the relationship between sharīʿa and siyāsa to reveal the extent and limits of sultanic power show a system of governance that allowed for the delegation of authority, particularly in the area of the judiciary, from the sultan down to viziers and judges. Some scholars depict the relationship between the ʿulamāʾ and the sultan as a kind of stand off. The actual dynamics of legal jurisdiction were much more complex. This study proposes a new interpretive framework for understanding the relationship between political power and religious authority through a critical analysis of the criminal judicial system, law, and historical narrative. In particular, I consider a murder case described by Shams al-dīn Sirāj ʿAfīf in one of the most significant histories written in the later Delhi Sultanate, the Tārīkh-i Fīrūzshāhī.

Power line communication in motor cables of variable-speed electric drives − analysis and

Data transmission between an electric motor and a frequency converter is required in variablespeed electric drives because of sensors installed at the motor. Sensor information can be used for various useful applications to improve the system reliability and its properties. Traditionally, the communication medium is implemented by an additional cabling. However, the costs of the traditional method may be an obstacle to the wider application of data transmission between a motor and a frequency converter. In any case, a power cable is always installed between a motor and a frequency converter for power supply, and hence it may be applied as a communication medium for sensor level data. This thesis considers power line communication (PLC) in inverter-fed motor power cables. The motor cable is studied as a communication channel in the frequency band of 100 kHz−30 MHz. The communication channel and noise characteristics are described. All the individual components included in a variable-speed electric drive are presented in detail. A channel model is developed, and it is verified by measurements. A theoretical channel information capacity analysis is carried out to estimate the opportunities of a communication medium. Suitable communication and forward error correction (FEC) methods are suggested. A general method to implement a broadband and Ethernet-based communication medium between a motor and a frequency converter is proposed. A coupling interface is also developed that allows to install the communication device safely to a three-phase inverter-fed motor power cable. Practical tests are carried out, and the results are analyzed. Possible applications for the proposed method are presented. A speed feedback motor control application is verified in detail by simulations and laboratory tests because of restrictions for the delay in the feedback loop caused by PLC. Other possible applications are discussed at a more general level.
