Diversification and its reflections on profitability - strategic change in pulp and paper industry in the years 1996 and 2006

The purpose of the thesis was to analyze diversification in pulp and paper industry (PPI), which is an industry facing enormous strategic challenges as many of the basic parameters of its operational environment are rapidly changing. The objective was to explore, how PPI companies have reacted to these changes by adjusting their strategies in terms of diversification and how the adjustments have affected their profitability. The study was statistical in nature. The results indicate that PPI companies in deed had reduced the degree of unrelated and related diversification , but the positive performance implications of the changes were debatable. In light of the data used in the study lower level of diversification did not lead to better profitability, in fact, the companies with the highest level of diversification had the best profitability. By contrast, reducing the level of unrelated diversification improved the profitability development; whereas reducing the level of related diversification deteriorated the profitability of the company. The results were not statistically significant and they cannot be generalized outside the data of the study.

Effects of business-to-business customer orientation, satisfaction and retention on firm profitability

The objective of this master’s thesis was to examine the effect of customer orientation on customer satisfaction and how customer satisfaction and customer retention contribute to firm profitability. Beside customer orientation, also other antecedents of customer satisfaction, i.e. service quality, flexibility, trust and commitment, were investigated as control variables. Literature review revealed several research gaps concerning research of the key concepts. These research calls were also answered. The empirical study focused on one case company, a telecommunication expert. The data for the empirical part was collected with web-based questionnaire from case company’s business customers in January-February 2008. Sample (N=95) produced 59 answers, thus the response rate of the survey was 62,1%. The data was analyzed by using statistical analysis program, SPSS. As a conclusion, the results indicate that customer orientation do not affect customer satisfaction directly, but through service quality, flexibility and trust. Moreover, customer satisfaction has positive impacts on commitment and intentions to stay as a customer in the future, but not on profitability. In the present study, only past purchase behavior, measured with customer database measure, is positively related to firm profitability.

PK-yrityksen investointimalli:robotin hankinnan kannattavuus

Työn tavoitteena oli tutkia robotti-investointia ja muodostaa siitä investointimalli, jossa selvitetään sen aiheuttamat kustannukset ja tuotot investointilaskelmien avulla. Investointimalli tehtiin siten, että sillä pystytään tutkimaan myös tulevia investointihankkeita. Robotti-investointi on luonteeltaan korvausinvestointi, joten sen toteuttamisessa on huomioitu tarkoin sille asetetut vaatimukset. Näiden perusteilla lähdettiin etsimään sopivaa laitetoimittajaa, joka pystyisi täyttämään annetut vaatimukset. Robottiaseman suunnittelu ja kehittäminen tehtiin vahvassa yhteistyössä laitetoimittajien kanssa, joilta saatiin myös tarvittavaa aineistoa teknisistä ominaisuuksista ja käytöstä aiheutuvista kustannuksista. Investoinnin kannattavuutta arvioitiin laskentamallin avulla, jonka tärkeimpinä kannattavuuden mittareina pidettiin takaisinmaksuaikaa ja nykyarvoa. Laskelmien tuloksiin liittyvää epävarmuutta arvioitiin herkkyysanalyysillä, jossa tutkittiin nykyarvon kehitystä eri tapauksissa. Investointia tutkittiin myös muista, kuin taloudellisista näkökulmista, joka vaikutti lopulliseen päätöksentekoon. Investointi muodostui erittäin kannattavaksi.

Growth Strategies in Pulp and Paper Industry: An Empirical Investigation on Profitability Effects

This study investigates whether there are differences in profitability of PPI companies based on the growth strategy they have chosen to follow. It is examined whether those companies following organic growth strategy are more profitable than those companies following acquisitive growth strategy. It is also investigated are ones larger than the others, or are ones growing faster than the others. Also, the factors affecting the profitability of acquisitive companies are further examined. The results showed that there actually are differences between the two groups. Organically grown companies were found to be more profitable, smaller and growing slower than acquisitive companies. When it comes to examining only acquisitive companies there could be found factors that better or worsen the profitability of companies. For example targets that the company has bought in developing markets were making them more profitable.

Calculation of the variance in surveys of the economic climate

Public opinion surveys have become progressively incorporated into systems of official statistics. Surveys of the economic climate are usually qualitative because they collect opinions of businesspeople and/or experts about the long-term indicators described by a number of variables. In such cases the responses are expressed in ordinal numbers, that is, the respondents verbally report, for example, whether during a given trimester the sales or the new orders have increased, decreased or remained the same as in the previous trimester. These data allow to calculate the percent of respondents in the total population (results are extrapolated), who select every one of the three options. Data are often presented in the form of an index calculated as the difference between the percent of those who claim that a given variable has improved in value and of those who claim that it has deteriorated.

Feasibility Study and Market Review of Small Scale Bioenergy Heating Plants in North-West Russia

The paper is focused on feasibility study and market review of small scale bioenergy heating plants in the Russian North-West region. The main focus is effective and competitive usage of low-grade wood for heating purposes in the region. As example of economical feasibility estimation it was chosen the project of reconstruction of small scale boiler plant in Leningrad region that Brofta Oy is planning to implement the nearest time. It includes calculation the payback time with and without interest, the estimation of probable investments, the evaluation of possible risks and research on the potential of small scale heating plants projects. Calculations show that the profitability of this kind of projects is high, but payback time is not very short, because of high level of initial investments. Though, the development of small scale bioenergy heating plants in the region is considered to be the best way to solve the problems of heat supply in small settlements using own biomass resources.

Analyzing customer profitability: an empirical study

The purpose of this study was to define the customer profitability of the case company as well as to specify the factors that explain customer profitability. The study was made with a quantitative research method. The research hypotheses were formulated mainly on the grounds of previous research, and were tested with statistical research methods. The research results showed that customer profitability is not equally distributed among the customers of the case company, and the majority of its customers is profitable. The interpreters for absolute customer profitability were sales volume and the customer’s location region. The interpreters for relative customer profitability were the customer’s location region and the product segment into which a customer can be classified on the basis of the products that were sold to this customer.

Piensarjatuotannon hitsauksen robotisointi

Diplomityön tarkoituksena on selvittää hitsauksen robotisointimahdollisuudet vakiintuneelle piensarjatuotteelle. Tarkastelun kohteeksi valittiin maanpäällisen porausyksikön runkopari, joka rakentuu ylä- ja alarungosta. Hitsaus on nykytilanteessa käsinhitsausta ja tuotetta tehdään noin 300 kpl / vuosi. Hitsauksen robotisoinnilla halutaan aikaansaada kustannussäästöä hitsauksen osalta ja tuotantokapasiteetin nousua. Työn teoriaosa voidaan jakaa neljään osaan: hitsaustekniikka, robottihitsattava tuote, robotisoituhitsaus ja investointilaskelmat. Hitsaustekniikassa lähdetään liikkeelle hitsauksen kannalta oleellisimmista perusasioista, jolloin lukijalle syntyy laajempi kokonaiskuva asiasta.

Robotisoidun hitsauksen osassa rakennetaan kokonaisuus, jolloin lopputuloksena on tehokas robottijärjestelmä. Samalla käsitellään sekä varsinaista hitsausteknistä toteutusta että robottijärjestelmän komponentteja. Investointilaskelmien avulla varmistetaan robottijärjestelmän ja koko tuotantoketjun kannattavuus. Käytännön osuudessa selvitetään robotisoidun hitsauksen mahdollisuudet valitulle tuotteelle ja robotisoinnin aikaansaamat kustannussäästöt. Tuotteen ylärungosta valitaan etuosa tarkempaa CASE tyylistä tarkastelua varten. CASE:ssa käydään läpi etuosan valmistettavuus ja selvitetään robotisoinnista aikaansaamat säästöt. Investointilaskelmien avulla selvitetään käytännön osuudessa robotisoidun hitsauksen kannattavuus tietyille robottijärjestelmille.

New approximation to the third-order density : application to the calculation of correlated multicenter indices

In this work we present the formulas for the calculation of exact three-center electron sharing indices (3c-ESI) and introduce two new approximate expressions for correlated wave functions. The 3c-ESI uses the third-order density, the diagonal of the third-order reduced density matrix, but the approximations suggested in this work only involve natural orbitals and occupancies. In addition, the first calculations of 3c-ESI using Valdemoro's, Nakatsuji's and Mazziotti's approximation for the third-order reduced density matrix are also presented for comparison. Our results on a test set of molecules, including 32 3c-ESI values, prove that the new approximation based on the cubic root of natural occupancies performs the best, yielding absolute errors below 0.07 and an average absolute error of 0.015. Furthemore, this approximation seems to be rather insensitive to the amount of electron correlation present in the system. This newly developed methodology provides a computational inexpensive method to calculate 3c-ESI from correlated wave functions and opens new avenues to approximate high-order reduced density matrices in other contexts, such as the contracted Schrödinger equation and the anti-Hermitian contracted Schrödinger equation

Calculation of the critical crack size for cold form rectangular hollow section tube (CRHS) under bending load at -40º C temperature

To predict the capacity of the structure or the point which is followed by instability, calculation of the critical crack size is important. Structures usually contain several cracks but not necessarily all of these cracks lead to failure or reach the critical size. So, defining the harmful cracks or the crack size which is the most leading one to failure provides criteria for structure’s capacity at elevated temperature. The scope of this thesis was to calculate fracture parameters like stress intensity factor, the J integral and plastic and ultimate capacity of the structure to estimate critical crack size for this specific structure. Several three dimensional (3D) simulations using finite element method by Ansys program and boundary element method by Frank 3D program were carried out to calculate fracture parameters and results with the aid of laboratory tests (loaddisplacement curve, the J resistance curve and yield or ultimate stress) leaded to extract critical size of the crack. Two types of the fracture which is usually affected by temperature, Elastic and Elasti-Plastic fractures were simulated by performing several linear elastic and nonlinear elastic analyses. Geometry details of the weldment; flank angle and toe radius were also studied independently to estimate the location of crack initiation and simulate stress field in early stages of crack extension in structure. In this work also overview of the structure’s capacity in room temperature (20 ºC) was studied. Comparison of the results in different temperature (20 ºC and -40 ºC) provides a threshold of the structure’s behavior within the defined range.
