Franchisingin soveltuvuus vanhustenhuoltolaitosten liiketoiminnassa

Työn tavoitteena on tutkia franchising-liiketoimintamallin soveltuvuutta kasvustrategiaksi vanhustenhuoltolaitosten toimialalla sekä mandollisuutta toteuttaa franchising-liiketoiminnan mukainen järjestelmä Finnish Wellbeing Center (FWBC) tyylisten vanhustenhuoltolaitosten monistamiseksi tämän hetkisistä Iähtokohdista. Yleisen soveltuvuuden tutkimista lähestytään kahdesta eri näkökulmasta, jotka myös muodostavat työn teoriaosuuden. Ensinnäkin perehdytään franchising liiketoimintamalliin perusteellisesti sekä käydään läpi soveltuvuustekijät hyvien ja huonojen puolien, toimialan luonteen ja franchisingiin sopivien liiketoimintakonseptien kannalta. Tämän jälkeen tutustutaan vanhustenhuollon palveluiden järjestämiseen. Palveluita tarjotaan erityylisissä palvelutiloissa riippuen vanhuksen kuntoisuusasteesta. Näistä valitaan päiväkeskukset, palveluasuminen sekä vanhainkodit franchisingin soveltuvuuden tarkasteluun. Työn empiriaosan tulokset viittaavat siihen, että vanhustenhuoltolaitosten soveltuvuus franchising-liiketoimintamalliin korreloi selvästi vanhusten kuntoisuusasteeseen. Päiväkeskusten liiketoimintaa voisi kasvattaa franchising menetelmällä, siinä missä palveluasumisen ja vanhainkotien soveltuvuus on vain teoreettinen. FWBC-projektissa franchising-liiketoimintamallia ei voida toteuttaa nykyisistä lähtökohdista, koska varsinainen franchisoitava toiminta ei ole täysin suomalaisen osapuolen hallussa. FWBC-vanhustenhuoltolaitos on vanhainkotityyppinen, joka ei sovellu franchisoitavaksi työn ensimmäisen johtopäätöksen perusteella. Mahdollisuus tämän hetkisen liiketoiminnan parantamiseen voisi löytyä tuotemerkki-franchisoinnista, jota nykyinen toimintatapa jo sinällään muistuttaa.

Mechanical design and optics simulation of the illuminated Volvo Iron mark

Utilization of light and illumination systems in automotive industry for different purposes has been increased significantly in recent years. Volvo as one of the leading companies in manufacturing of luxury cars has found the great capacity in this area. The performance of such an illumination systems is one of the challenges that engineers in this industry are facing with. In this study an effort has been made to design a system to make the iron mark of Volvo being illuminated and the system is being evaluated by optics simulation in software using Ray optics method. At the end, results are assessed and some optimizations are carried out. Different kind of light guides, front side of the iron mark and some possible arrangement for LED also evaluated and different materials tested. The best combination from uniformity, color and amount of luminance aspect selected as a possible solution for this special project which can be used as a base for further studies in Volvo.

Abstract

Effective notch method assessment of misalignment for fatigue loaded welds

 The objective of this thesis work was to assess axial misalignment in fatigue loaded welds using the effective notch method. As a result, the fatigue behaviour of non-load carrying cruciform fillet welded joint under cyclic tensile loading has been studied. Various degrees of axial misalignment have been found in one series of non-load carrying cruciform fillet welded joints used in a laboratory investigation. As a result, it was important to carry out a comprehensive investigation since axial misalignment forms part of thequality of fatigue loaded structure and can reduce the fatigue strength. To extend the study, the correlation between fatigue strength and stress ratio, as well as stress concentration factor, were also studied. Moreover, a closer investigation of place of crack initiation and its dependence on weld sequence and imperfections of test specimen (angular distortion) was studied. For the fatigue class calculations, FEM (finite element method) and the effectivenotch approach are used. The addressed variable is the axial misalignment whichis introduce by modeling the entire joint. Fracture mechanics based calculations are also used and quantitatively compared with effective notch and experimental results.

Optimisation of data analysis method for a fluidized bed combustion test rig

Nowadays the used fuel variety in power boilers is widening and new boiler constructions and running models have to be developed. This research and development is done in small pilot plants where more faster analyse about the boiler mass and heat balance is needed to be able to find and do the right decisions already during the test run. The barrier on determining boiler balance during test runs is the long process of chemical analyses of collected input and outputmatter samples. The present work is concentrating on finding a way to determinethe boiler balance without chemical analyses and optimise the test rig to get the best possible accuracy for heat and mass balance of the boiler. The purpose of this work was to create an automatic boiler balance calculation method for 4 MW CFB/BFB pilot boiler of Kvaerner Pulping Oy located in Messukylä in Tampere. The calculation was created in the data management computer of pilot plants automation system. The calculation is made in Microsoft Excel environment, which gives a good base and functions for handling large databases and calculations without any delicate programming. The automation system in pilot plant was reconstructed und updated by Metso Automation Oy during year 2001 and the new system MetsoDNA has good data management properties, which is necessary for big calculations as boiler balance calculation. Two possible methods for calculating boiler balance during test run were found. Either the fuel flow is determined, which is usedto calculate the boiler's mass balance, or the unburned carbon loss is estimated and the mass balance of the boiler is calculated on the basis of boiler's heat balance. Both of the methods have their own weaknesses, so they were constructed parallel in the calculation and the decision of the used method was left to user. User also needs to define the used fuels and some solid mass flowsthat aren't measured automatically by the automation system. With sensitivity analysis was found that the most essential values for accurate boiler balance determination are flue gas oxygen content, the boiler's measured heat output and lower heating value of the fuel. The theoretical part of this work concentrates in the error management of these measurements and analyses and on measurement accuracy and boiler balance calculation in theory. The empirical part of this work concentrates on the creation of the balance calculation for the boiler in issue and on describing the work environment.
