Tiedon hajautus johtamisjärjestelmässä ja DDS-teknologia

Verkostokeskeisessä sodankäynnissä tietojärjestelmien suurimpana haasteena on oikean tiedon hajauttaminen oikeaan paikkaan ja aikaan. Tietojärjestelmissä esitettävän ilmatilannekuvan tulee vastata reaalimaailman tilannetta parhaalla mahdollisella tavalla. Ilmatorjunnassa reaaliaikaisuus nousee erityisen suureen rooliin nopeasti liikkuvien kohteiden takia. Tämä diplomityö on tehty Insta DefSec Oy:ssä liittyen johtamisjärjestelmän uudistamishankkeeseen. Työn vaatimuksina olivat standardeihin perustuvat ratkaisut, joista keskeisimmäksi nousi Data Distribution Service -standardi (DDS) ja sen hyödyntäminen osana johtamisjärjestelmän tiedon hajautusta. Työssä esitellään johtamisjärjestelmien tiedon hajautukseen liittyviä haasteita sekä paikallisessa että maantieteellisesti hajautetussa toimintaympäristössä. Työssä toteutettiin liityntäohjelmisto nykyisen ja uuden johtamisjärjestelmän välille. Liityntäohjelmiston tehtävänä on tuottaa reaaliaikaista ilmatilannekuvaa nykyisestä johtamisjärjestelmästä uuteen johtamisjärjestelmään. DDS-standardin toteuttavana välikerrosarkkitehtuurina käytettiin OpenSplice DDS -tuotetta. Valittu teknologia tarjoaa edistykselliset julkaisija–tilaaja-mallin mukaiset menetelmät tiedon reaaliaikaiseen hajauttamiseen. DDS:n arkkitehtuuri ja palvelun laadun mekanismit mahdollistavat tiedon hajautuksen sodanajan johtamisjärjestelmille.

Tuotteen elinkaarenaikainen tiedonhallinta palvelukeskeisen arkkitehtuurin avulla

Palvelukeskeistä arkkitehtuuria (SOA) sovelletaan nykyään varsinkin suurten yritysten tietojärjestelmien suunnittelussa ja toteutuksessa. Siinä toiminnot suunnitellaan palveluina, mikä lisää erityisesti palveluiden uudelleen-käytettävyyttä ja mahdollisuutta hyödyntää jo tehtyjä järjestelmäinvestointeja. Tuotteen elinkaarenaikaisen tiedonhallinnan (PLM) pyrkimyksenä on saada elinkaarelle hajaantunut tieto käyttöön oikeassa paikassa oikeaan aikaan sekä parantaa tuotetiedon luotettavuutta ja ajantasaisuutta. Tämä on yksi tärkeimmistä tekijöistä tavoiteltaessa kilpailuetuja verkottuneessa liiketoiminnassa. Tämän diplomityön tavoitteena oli selvittää, kuinka tuotteen elinkaarenaikainen tiedonhallinta voidaan toteuttaa palvelukeskeisen arkkitehtuurin avulla sekä, mitä haasteita ja hyötyjä tästä seuraa organisaatiolle. Tutkimus tehtiin kirjallisuustutkimuksena. Työ tarjoaa tietoa PLM:n ja SOA:n integroinnista sekä integroinnin haasteista ja hyödyistä. Tutkimuksen tulokset osoittavat palvelukeskeisen PLM:n tuovan oikein suunniteltuna ja toteutettuna merkittäviä hyötyjä verkostoituneessa ympäristössä toimiville yrityksille. Lisäksi työ antaa käsityksen siitä, kuinka laaja projekti palvelukeskeisen PLM:n implementointi on.

Outsourcing process in pharmaceutical product development

The aim of this study was to create an outsourcing process for pharmaceutical product development. This study focuses on two main questions. The first question is “What is the outsourcing process model?” In the second phase key success factors of the outsourcing process are identified. As a result of the literature reviews, a general outsourcing process was created. Transaction cost economics and resource based view were used to derived a theoretical framework to the process by combining the existing processes presented in the literature. The model of process is considered used to the outsourcing broadly. The general outsourcing process was then developed further with the key factors that affect the success of pharmaceutical product development and the interviews of pharmaceutical outsourcing experts. The result of the research was the process consists of seven phases with key activities and expected outputs for each of the phases. In addition, the strategic decision-making framework for outsourcing decision in pharmaceutical product development is giving as well as the tools for selecting supplier and preparing structured contract. This study also gives some recommendations for managing the outsourcing process.

Suunnittelukapasiteettien seurantamallin kehittäminen

The first main objective of this study was to develop a planning capacity management model for a chocolate and confectionary company in Finland. The second objective was to analyze how capacity updates would affect cost accounting practices. In addition, a creation of an update and maintenance process of planning capacities was determined as a sub-objective of developing the capacity management model. The thesis was started with analyzing the needs, requirements and constraints of the capacity management model and model’s connection with cost accounting. This was done by interviewing key officials like production planners, managers and controllers. A thorough literature review was also done at an early phase. Furthermore, internal systems and software architecture got to be acquainted with. The model was constructed as an Excel-based platform which will get its input data from Enterprise Resource Planning system and Production Performance Measurement system. The main purpose of the planning capacity management model is to make sure that the production planners can utilize more precise parameters but it also offers tools for the production managers to assess production performance and effectiveness at the product level. In addition to production planning, planning capacities are also tightly involved with cost accounting as many direct and indirect costs are allocated to the products utilizing planning capacities. For this reason, the linkage between product costing and capacity is also diversely examined in the thesis. Development suggestions conclude the report by giving some guidelines for more precise and consistent production planning and cost accounting between the factories.

Modulointia ohjaavien tekijöiden valinta asiakkaiden, tuotekehityksen ja valmistuksen vaatimusten perusteella

Modular drivers cover the entire product life cycle and when the most important modular drivers are known, it is possible to focus on the most essential areas in modularization. Modular drivers are helpful while planning modularization, selecting modules to manufacture and evaluating the success of the modularization. When the modules are formed based on the modular drivers it is also possible to develop production processes according to the requirements of a certain module. The objective of the Master’s Thesis was to organize the modular drivers based on the weightings in order to make the modularization process easier. The phases to find the most important module drivers were formed based on the existing literature and background material from the company. During the Master’s Thesis project the weights of the modular drivers were determined according to the requirements of customers, product development and manufacturing. The requirements were established by a questionnaire and the weights for the requirements were selected in an interview using the Analytic Hierarchy Process. The modular drivers were compared pairwise by the view point of the requirements of certain group. When the results of the three groups were integrated, the weights of the modular drivers were found and it was possible to select the most important drivers.

Product costing model for laser welded hollow core steel panels

The aim of the study was to create an easily upgradable product costing model for laser welded hollow core steel panels to help in pricing decisions. The theory section includes a literature review to identify traditional and modern cost accounting methodologies, which are used by manufacturing companies. The theory section also presents the basics of steel panel structures and their manufacturing methods and manufacturing costs based on previous research. Activity-Based costing turned out to be the most appropriate methodology for the costing model because of wide product variations. Activity analysis and the determination of cost drivers based on observations and interviews were the key steps in the creation of the model. The created model was used to test how panel parameters affect the costs caused by the main manufacturing stages and materials. By comparing cost structures, it was possible to find the panel types that are the most economic and uneconomic to manufacture. A sensitivity analysis proved that the model gives sufficiently reliable cost information to support pricing decisions. More reliable cost information could be achieved by determining the cost drivers more accurately. Alternative methods for manufacturing the cores were compared with the model. The comparison proved that roll forming can be more advantageous and flexible than press brake bending. However, more extensive research showed that roll forming is possible only when the cores are designed to be manufactured by roll forming. Due to that fact, when new panels are designed consideration should be given to the possibility of using roll forming.

Examining the Role of Rebranding in Perceived Image of a Product Line

The main objective for this study was to explore certain organization’s product line rebranding process and its impact on product line’s perceived image. The case company is a global paper, packaging and forest products company, business segment paper board. The audience explored is one of the company’s major customers, merchant in Germany. The research was performed as a descriptive case study with a purpose to provide longitudinal insight into the product line image and its eventual alteration as a result of the case company’s rebranding process. Mainly qualitative methods were used for conducting the research. The data for the empirical part was collected with a web-based survey at two different points of time; before the rebranded products entered the market and after they had been available approximately six months. The results of this study reveal that the case company has performed well in its attempt to improve product line’s brand image through rebranding. It was found that between the two brand image measurements the product brand image seems to have improved in all of the areas which according to theoretical framework of this study contribute to formation of brand image; brand associations, marketing communications and interpersonal relationships, not forgetting the original platform that initiated the change; technical quality modifications. In other words it may be concluded that as technical quality was brought to a new level, also assessments about the brand image improved respectively.

Modulaarinen kiinnitintekniikka alumiiniveneiden robottihitsauksessa

Tällä hetkellä hitsauksen automatisointiaste on hyvin pieni alumiinivenevalmistuksessa. Automatisointiasteen kasvattaminen on ensiarvoisen tärkeää kilpailukyvyn säilyttämiseksi, sekä edelleen nostamiseksi. Automatisointiasteen kasvattamisen esteenä ei ole teknologian puute, vaan suunnitellut tuotteet soveltuvat huonosti robotisoituun hitsaukseen. Lisäksi liitettävien osien tarkkuus on monissa tapauksissa puutteellinen, joten robottihitsaus on monessa tapauksessa mahdotonta. Robottihitsauksessa vaaditaan osien hyvää paikoittamista ja siihen tarvitaan kiinnittimiä. Kuitenkin alumiinivenevalmistuksessa valmistusmäärät ovat sen verran pieniä, että tuotekohtaisia kiinnittimiä ei kannata hankkia tai valmistaa. Siksi kiinnittimiltä vaaditaan joustavuutta ja modulaarisuutta, jotta samalla kiinnittimellä voi hitsata useita vastaavia piirteitä omaavia tuotteita. Tässä työssä tutkittiin modulaarisia kiinnittimiä, edistyneitä kiinnitinsuunnitteluprosesseja, osavalmistustarkkuuksia, tuotemoduloinnin hyödyntämistä ja alumiinin robottihitsauksen erityispiirteitä. Työssä suunniteltiin ja simuloitiin modulaarinen hitsauskiinnitin, jota käytetään tietyn alumiinivenemallin erillisenä osakokoonpanona valmistettavan jäykisterakennekonseptin hitsaamiseen. Suunnittelu ja simulointi tehtiin Delmia V5R20 -ohjelmistolla. Jäykisterakenne on modulaarinen tuoterakenne, jossa käytetään itsepaikoittavia liitoksia helpottamaan osien asettelua ja yksinkertaistamaan kiinnitintä. Kiinnitin soveltuu joustavasti erikokoisten jäykisterakenneosakokoonpanojen valmistukseen. Lisäksi suunniteltua kiinnitintä verrattiin kaupalliseen modulaariseen Demmeler -kiinnitinjärjestelmään. Jäykisterakenteen osakokoonpanon hitsaaminen robotilla lyhentää valmistusaikaa verrattuna nykytilaan, kun osat voidaan asettaa kiinnittimeen nopeasti ja luotettavasti. Samalla jäykisterakenteen tekeminen erillisenä osakokoonpanona lyhentää veneen rungon loppukokoonpanoaikaa ja mahdollistaa hitsausrobotin käytön myös veneen muiden hitsien hitsaamisessa. Modulaarisilla hitsauskiinnittimillä saavutetaan alumiiniveneiden nykyisillä valmistusmäärillä skaalaetuja, joita tuotekohtaisella kiinnittimellä ei voi saavuttaa.

The Role of Tactical Marketing Decisions on New Product Performance: The Moderating Effect of Entry Timing

This study focuses on observing how Finnish companies execute their new product launch processes. The main objective was to find out how entry timing moderates the relationship between launch tactics (namely product innovativeness, price and emotional advertising) and new product performance (namely sales volume and customer profitability). The empirical analysis was based on data collected in Lappeenranta University of Technology. The sample consisted of Finnish companies representing different industries and innovation activities. Altogether 272 usable responses were received representing a response rate of 37.67%. The measures were first assessed by using exploratory factor analysis (EFA) in PASW Statistics 18 and then further verified with confirmatory factor analysis (CFA) in LISREL 8.80. To test the hypotheses of the moderating effects of entry timing, hierarchical regression analysis was used in PASW Statistics 18. The results of the study revealed that the effect of product innovativeness on new product sales volume is dependent on entry timing. This implies that companies should carefully consider what would be the best time for entering the market when launching highly innovative new products. The results also depict a positive relationship between emotional advertising and new product sales volume. In addition, partial support was found for a positive relationship between pricing and new product customer profitability.

Integrating environmental aspects into product development process

Various regulations and customer requirements have made it necessary for Vacon Oyj to pay more attention to the environmental aspects in its processes. The main purpose of this master’s thesis project is to define how environmental aspects could be integrated into Vacon’s product development process. The aim is to find out the most important environmental aspects for the company to address, to examine how these could be taken into account during the development process and to map the critical factors that need consideration in order to ensure the successful integration of environmental aspects into the design process. Based on the customer requirements and evolving regulations the most important aspects for Vacon include minimizing the amount of harmful substances, improving the recyclability and energy efficiency of the product and moreover providing meaningful information related to these aspects. To tackle these issues, a new DfE process was developed, tasks in each phase were described and responsibilities were indicated. To ensure the success of the DfE process, management commitment, support of other processes and significant improvements in ways the information is managed are required. The developers should be provided with training and support. Environmental expertise and knowledge in-house should be developed and establishing meaningful environmental indicators is suggested.

Recovery and refining of manganese as by-product from hydrometallurgical processes

The consumption of manganese is increasing, but huge amounts of manganese still end up in waste in hydrometallurgical processes. The recovery of manganese from multi-metal solutions at low concentrations may not be economical. In addition, poor iron control typically prevents the production of high purity manganese. Separation of iron from manganese can be done with chemical precipitation or solvent extraction methods. Combined carbonate precipitation with air oxidation is a feasible method to separate iron and manganese due to the fast kinetics, good controllability and economical reagents. In addition the leaching of manganese carbonate is easier and less acid consuming than that of hydroxide or sulfide precipitates. Selective iron removal with great efficiency from MnSO4 solution is achieved by combined oxygen or air oxidation and CaCO3 precipitation at pH > 5.8 and at a redox potential of > 200 mV. In order to avoid gypsum formation, soda ash should be used instead of limestone. In such case, however, extra attention needs to be paid on the reagents mole ratios in order to avoid manganese coprecipitation. After iron removal, pure MnSO4 solution was obtained by solvent extraction using organophosphorus reagents, di-(2-ethylhexyl)phosphoric acid (D2EHPA) and bis(2,4,4- trimethylpentyl)phosphinic acid (CYANEX 272). The Mn/Ca and Mn/Mg selectivities can be increased by decreasing the temperature from the commonly used temperatures (40 –60oC) to 5oC. The extraction order of D2EHPA (Ca before Mn) at low temperature remains unchanged but the lowering of temperature causes an increase in viscosity and slower phase separation. Of these regents, CYANEX 272 is selective for Mn over Ca and, therefore, it would be the better choice if there is Ca present in solution. A three-stage Mn extraction followed by a two-stage scrubbing and two-stage sulfuric acid stripping is an effective method of producing a very pure MnSO4 intermediate solution for further processing. From the intermediate MnSO4 some special Mn- products for ion exchange applications were synthesized and studied. Three types of octahedrally coordinated manganese oxide materials as an alternative final product for manganese were chosen for synthesis: layer structured Nabirnessite, tunnel structured Mg-todorokite and K-kryptomelane. As an alternative source of pure MnSO4 intermediate, kryptomelane was synthesized by using a synthetic hydrometallurgical tailings. The results show that the studied OMS materials adsorb selectively Cu, Ni, Cd and K in the presence of Ca and Mg. It was also found that the exchange rates were reasonably high due to the small particle dimensions. Materials are stable in the studied conditions and their maximum Cu uptake capacity was 1.3 mmol/g. Competitive uptake of metals and acid was studied using equilibrium, batch kinetic and fixed-bed measurements. The experimental data was correlated with a dynamic model, which also accounts for the dissolution of the framework manganese. Manganese oxide micro-crystals were also bound onto silica to prepare a composite material having a particle size large enough to be used in column separation experiments. The MnOx/SiO2 ratio was found to affect significantly the properties of the composite. The higher the ratio, the lower is the specific surface area, the pore volume and the pore size. On the other hand, higher amount of silica binder gives composites better mechanical properties. Birnesite and todorokite can be aggregated successfully with colloidal silica at pH 4 and with MnO2/SiO2 weight ratio of 0.7. The best gelation and drying temperature was 110oC and sufficiently strong composites were obtained by additional heat-treatment at 250oC for 2 h. The results show that silica–supported MnO2 materials can be utilized to separate copper from nickel and cadmium. The behavior of the composites can be explained reasonably well with the presented model and the parameters estimated from the data of the unsupported oxides. The metal uptake capacities of the prepared materials were quite small. For example, the final copper loading was 0.14 mmol/gMnO2. According to the results the special MnO2 materials are potential for a specific environmental application to uptake harmful metal ions.

Exploring Adaptive Implementation of On-Chip Networks

As technology geometries have shrunk to the deep submicron regime, the communication delay and power consumption of global interconnections in high performance Multi- Processor Systems-on-Chip (MPSoCs) are becoming a major bottleneck. The Network-on- Chip (NoC) architecture paradigm, based on a modular packet-switched mechanism, can address many of the on-chip communication issues such as performance limitations of long interconnects and integration of large number of Processing Elements (PEs) on a chip. The choice of routing protocol and NoC structure can have a significant impact on performance and power consumption in on-chip networks. In addition, building a high performance, area and energy efficient on-chip network for multicore architectures requires a novel on-chip router allowing a larger network to be integrated on a single die with reduced power consumption. On top of that, network interfaces are employed to decouple computation resources from communication resources, to provide the synchronization between them, and to achieve backward compatibility with existing IP cores. Three adaptive routing algorithms are presented as a part of this thesis. The first presented routing protocol is a congestion-aware adaptive routing algorithm for 2D mesh NoCs which does not support multicast (one-to-many) traffic while the other two protocols are adaptive routing models supporting both unicast (one-to-one) and multicast traffic. A streamlined on-chip router architecture is also presented for avoiding congested areas in 2D mesh NoCs via employing efficient input and output selection. The output selection utilizes an adaptive routing algorithm based on the congestion condition of neighboring routers while the input selection allows packets to be serviced from each input port according to its congestion level. Moreover, in order to increase memory parallelism and bring compatibility with existing IP cores in network-based multiprocessor architectures, adaptive network interface architectures are presented to use multiple SDRAMs which can be accessed simultaneously. In addition, a smart memory controller is integrated in the adaptive network interface to improve the memory utilization and reduce both memory and network latencies. Three Dimensional Integrated Circuits (3D ICs) have been emerging as a viable candidate to achieve better performance and package density as compared to traditional 2D ICs. In addition, combining the benefits of 3D IC and NoC schemes provides a significant performance gain for 3D architectures. In recent years, inter-layer communication across multiple stacked layers (vertical channel) has attracted a lot of interest. In this thesis, a novel adaptive pipeline bus structure is proposed for inter-layer communication to improve the performance by reducing the delay and complexity of traditional bus arbitration. In addition, two mesh-based topologies for 3D architectures are also introduced to mitigate the inter-layer footprint and power dissipation on each layer with a small performance penalty.

Network effects: Scale development and implications for new product performance

More and more innovations currently being commercialized exhibit network effects, in other words, the value of using the product increases as more and more people use the same or compatible products. Although this phenomenon has been the subject of much theoretical debate in economics, marketing researchers have been slow to respond to the growing importance of network effects in new product success. Despite an increase in interest in recent years, there is no comprehensive view on the phenomenon and, therefore, there is currently incomplete understanding of the dimensions it incorporates. Furthermore, there is wide dispersion in operationalization, in other words, the measurement of network effects, and currently available approaches have various shortcomings that limit their applicability, especially in marketing research. Consequently, little is known today about how these products fare on the marketplace and how they should be introduced in order to maximize their chances of success. Hence, the motivation for this study was driven by the need to increase our knowledge and understanding of the nature of network effects as a phenomenon, and of their role in the commercial success of new products. This thesis consists of two parts. The first part comprises a theoretical overview of the relevant literature, and presents the conclusions of the entire study. The second part comprises five complementary, empirical research publications. Quantitative research methods and two sets of quantitative data are utilized. The results of the study suggest that there is a need to update both the conceptualization and the operationalization of the phenomenon of network effects. Furthermore, there is a need for an augmented view on customers’ perceived value in the context of network effects, given that the nature of value composition has major implications for the viability of such products in the marketplace. The role of network effects in new product performance is not as straightforward as suggested in the existing theoretical literature. The overwhelming result of this study is that network effects do not directly influence product success, but rather enhance or suppress the influence of product introduction strategies. The major contribution of this study is in conceptualizing the phenomenon of network effects more comprehensively than has been attempted thus far. The study gives an augmented view of the nature of customer value in network markets, which helps in explaining why some products thrive on these markets whereas others never catch on. Second, the study discusses shortcomings in prior literature in the way it has operationalized network effects, suggesting that these limitations can be overcome in the research design. Third, the study provides some much-needed empirical evidence on how network effects, product introduction strategies, and new product performance are associated. In general terms, this thesis adds to our knowledge of how firms can successfully leverage network effects in product commercialization in order to improve market performance.
