Thermogenesis in obese women: effect of fructose vs. glucose added to a meal.

To assess the effect of a fructose meal on resting energy expenditure (EE), indirect calorimetry was used in 23 women (10 lean and 13 obese) for 30 min before and 6 h after the ingestion of a mixed meal containing 20% protein, 33% fat, and either 75 g glucose or 75 g fructose as carbohydrate source (47%). Expressed as a percentage of the energy content of the meal, the thermogenic response to the fructose meal was significantly greater (10.2 +/- 0.5%) than that of the glucose meal (8.4 +/- 0.4%, P less than 0.01). This difference was still apparent when the lean and obese women were considered separately. The mean respiratory quotient during the 6-h postprandial period was significantly greater (P less than 0.01) for the fructose (0.85 +/- 0.01) than for the glucose meal (0.83 +/- 0.01) in the combined subjects. In addition, cumulative carbohydrate oxidation was significantly greater after the fructose than after the glucose meal (51.1 +/- 2.3 vs. 40.9 +/- 2.0 g/6 h, respectively, P less than 0.01). Only small changes were observed in postprandial plasma levels of glucose and insulin after the fructose meal, but the plasma levels of lactate increased more with fructose than with the glucose meal. These results suggest that there might be some advantages (higher thermogenesis and carbohydrate oxidations) in using fructose as part of the carbohydrate source in diet of people with obesity and/or insulin resistance.

Contribution of isotope ratio mass spectrometry to the investigation of improvised explosives: isotopic study of black powders ans ammonium nitrates

The establishment of legislative rules about explosives in the eighties has reduced the illicit use of military and civilian explosives. However, bomb-makers have rapidly taken advantage of substances easily accessible and intended for licit uses to produce their own explosives. This change in strategy has given rise to an increase of improvised explosive charges, which is moreover assisted by the ease of implementation of the recipes, widely available through open sources. While the nature of the explosive charges has evolved, instrumental methods currently used in routine, although more sensitive than before, have a limited power of discrimination and allow mostly the determination of the chemical nature of the substance. Isotope ratio mass spectrometry (IRMS) has been applied to a wide range of forensic materials. Conclusions drawn from the majority of the studies stress its high power of discrimination. Preliminary studies conducted so far on the isotopic analysis of intact explosives (pre-blast) have shown that samples with the same chemical composition and coming from different sources could be differentiated. The measurement of stable isotope ratios appears therefore as a new and remarkable analytical tool for the discrimination or the identification of a substance with a definite source. However, much research is still needed to assess the validity of the results in order to use them either in an operational prospect or in court. Through the isotopic study of black powders and ammonium nitrates, this research aims at evaluating the contribution of isotope ratio mass spectrometry to the investigation of explosives, both from a pre-blast and from a post-blast approach. More specifically, the goal of the research is to provide additional elements necessary to a valid interpretation of the results, when used in explosives investigation. This work includes a fundamental study on the variability of the isotopic profile of black powder and ammonium nitrate in both space and time. On one hand, the inter-variability between manufacturers and, particularly, the intra-variability within a manufacturer has been studied. On the other hand, the stability of the isotopic profile over time has been evaluated through the aging of these substances exposed to different environmental conditions. The second part of this project considers the applicability of this high-precision technology to traces and residues of explosives, taking account of the characteristics specific to the field, including their sampling, a probable isotopic fractionation during the explosion, and the interferences with the matrix of the site.

Fast gas chromatography and negative-ion chemical ionization tandem mass spectrometry for forensic analysis of cannabinoids in whole blood.

The present work describes a fast gas chromatography/negative-ion chemical ionization tandem mass spectrometric assay (Fast GC/NICI-MS/MS) for analysis of tetrahydrocannabinol (THC), 11-hydroxy-tetrahydrocannabinol (THC-OH) and 11-nor-9-carboxy-tetrahydrocannabinol (THC-COOH) in whole blood. The cannabinoids were extracted from 500 microL of whole blood by a simple liquid-liquid extraction (LLE) and then derivatized by using trifluoroacetic anhydride (TFAA) and hexafluoro-2-propanol (HFIP) as fluorinated agents. Mass spectrometric detection of the analytes was performed in the selected reaction-monitoring mode on a triple quadrupole instrument after negative-ion chemical ionization. The assay was found to be linear in the concentration range of 0.5-20 ng/mL for THC and THC-OH, and of 2.5-100 ng/mL for THC-COOH. Repeatability and intermediate precision were found less than 12% for all concentrations tested. Under standard chromatographic conditions, the run cycle time would have been 15 min. By using fast conditions of separation, the assay analysis time has been reduced to 5 min, without compromising the chromatographic resolution. Finally, a simple approach for estimating the uncertainty measurement is presented.

Flow phenomena, heat and mass transfer in microchannel reactors

The studies of flow phenomena, heat and mass transfer in microchannel reactors are beneficial to estimate and evaluate the ability of microchannel reactors to be operated for a given process reaction such as Fischer-Tropsch synthesis. The flow phenomena, for example, the flow regimes and flow patterns in microchannel reactors for both single phase and multiphase flow are affected by the configuration of the flow channel. The reviews of the previous works about the analysis of related parameters that affect the flow phenomena are shown in this report. In order to predict the phenomena of Fischer-Tropsch synthesis in microchannel reactors, the 3-dimensional computational fluid dynamic simulation with commercial software package FLUENT was done to study the flow phenomena and heat transfer for gas phase Fischer-Tropsch products flow in rectangular microchannel with hydraulic diameter 500 ¿m and length 15 cm. Numerical solution with slip boundary condition was used in the simulation and the flowphenomena and heat transfer were determined.

Lifecycle Information Management of a Mass Customized Product

Diplomityön tavoitteena on tutkia mitä uusia tiedonhallinnallisia ongelmia ilmenee, kun massaräätälöidyn tuotteen tuotetieto hallitaan läpi tuotteen elinkaaren, sekä miten nämä ongelmat voitaisiin ratkaista. Ongelmat ja haasteet kerätään kirjallisuuslähteistä ja massaräätälöintiprosessi yhdistetään PLM-vaiheisiin. Ratkaisua tutkitaan testaamalla kuinka standardit STEP ja PLCS sekä standardeja tukeva PLM järjestelmä voisivat tukea massaräätälöidyn tuotteen elinkaaren tiedonhallintaa. MC tuotteiden ongelmia ovat tuoterakenteen monimutkaisuus, jäljitettävyys ja muutosten hallinta läpi elinkaaren. STEP ja PLCS pystyvät kummatkin tahollaan tukemaan tiedonhallintaa. MC-tuotteen geneerinen tuoterakenne on kuitenkin manuaalisesti liittettävä elinkaaritiedon tukemiseen. PLM-järjestelmä pystyy tukemaan MC-tuotteiden elinkaarta, mutta koska toiminto ei ole järjestelmään sisäänrakennettuna, MC-tuotteiden tukemisen parantamisessa on edelleen haasteita.

Reexamination of the relationship of resting metabolic rate to fat-free mass and to the metabolically active components of fat-free mass in humans.

The ratio of resting metabolic rate (RMR) to fat-free mass (FFM) is often used to compare individuals of different body sizes. Because RMR has not been well described over the full range of FFM, a literature review was conducted among groups with a wide range of FFM. It included 31 data sets comprising a total of 1111 subjects: 118 infants and preschoolers, 323 adolescents, and 670 adults; FFM ranged from 2.8 to 106 kg. The relationship of RMR to FFM was found to be nonlinear and average slopes of the regression equations of the three groups differed significantly (P less than 0.0001). For only the youngest group did the intercept approach zero. The lower slopes of RMR on FFM, at higher measures of FFM, corresponded to relatively greater proportions of less metabolically active muscle mass and to lesser proportions of more metabolically active nonmuscle organ mass. Because the contribution of FFM to RMR is not constant, an arithmetic error is introduced when the ratio of RMR to FFM is used. Hence, alternative methods should be used to compare individuals with markedly different FFM.

FTO genetic variants, dietary intake and body mass index: insights from 177,330 individuals.

FTO is the strongest known genetic susceptibility locus for obesity. Experimental studies in animals suggest the potential roles of FTO in regulating food intake. The interactive relation among FTO variants, dietary intake and body mass index (BMI) is complex and results from previous often small-scale studies in humans are highly inconsistent. We performed large-scale analyses based on data from 177,330 adults (154 439 Whites, 5776 African Americans and 17 115 Asians) from 40 studies to examine: (i) the association between the FTO-rs9939609 variant (or a proxy single-nucleotide polymorphism) and total energy and macronutrient intake and (ii) the interaction between the FTO variant and dietary intake on BMI. The minor allele (A-allele) of the FTO-rs9939609 variant was associated with higher BMI in Whites (effect per allele = 0.34 [0.31, 0.37] kg/m(2), P = 1.9 × 10(-105)), and all participants (0.30 [0.30, 0.35] kg/m(2), P = 3.6 × 10(-107)). The BMI-increasing allele of the FTO variant showed a significant association with higher dietary protein intake (effect per allele = 0.08 [0.06, 0.10] %, P = 2.4 × 10(-16)), and relative weak associations with lower total energy intake (-6.4 [-10.1, -2.6] kcal/day, P = 0.001) and lower dietary carbohydrate intake (-0.07 [-0.11, -0.02] %, P = 0.004). The associations with protein (P = 7.5 × 10(-9)) and total energy (P = 0.002) were attenuated but remained significant after adjustment for BMI. We did not find significant interactions between the FTO variant and dietary intake of total energy, protein, carbohydrate or fat on BMI. Our findings suggest a positive association between the BMI-increasing allele of FTO variant and higher dietary protein intake and offer insight into potential link between FTO, dietary protein intake and adiposity.

Diagnostic accuracy of body mass index, body fat and waist in defining low aerobic fitness in adolescents

Objective: to assess the diagnostic accuracy of different anthropometric markers in defining low aerobic fitness among adolescents. Methods: cross-sectional study on 2,331 boys and 2,366 girls aged 10 - 18 years. Body mass index (BMI) was measured using standardized methods; body fat (BF) was assessed by bioelectrical impedance. Low aerobic fitness was assessed by the 20-meter shuttle run using the FITNESSGRAMR criteria. Waist was measured in a subsample of 1,933 boys and 1,897 girls. Overweight, obesity and excess fat were defined according to the International Obesity Task Force (IOTF) or FITNESSGRAMR criteria. Results: 38.5% of boys and 46.5% of girls were considered as unfit according to the FITNESSGRAMR criteria. In boys, the area under the ROC curve (AUC) and 95% confidence interval were 66.7 (64.1 - 69.3), 67.1 (64.5 - 69.6) and 64.6 (61.9 - 67.2) for BMI, BF and waist, respectively (P<0.02). In girls, the values were 68.3 (65.9 - 70.8), 63.8 (61.3 - 66.3) and 65.9 (63.4 - 68.4), respectively (P<0.001). In boys, the sensitivity and specificity to diagnose low fitness were 13% and 99% for obesity (IOTF); 38% and 86% for overweight + obesity (IOTF); 28% and 94% for obesity (FITNESSGRAMR) and 42% and 81% for excess fat (FITNESSGRAMR). For girls, the values were 9% and 99% for obesity (IOTF); 33% and 82% for overweight + obesity (IOTF); 22% and 94% for obesity (FITNESSGRAMR) and 26% and 90% for excess fat (FITNESSGRAMR). Conclusions: BMI, not body fat or waist, should be used to define low aerobic fitness. The IOTF BMI cut-points to define obesity have a very low screening capacity and should not be used.

Value added logistical support service. Part 1 : Trends and new concept model

The aim of `Valssi' study was to find out the service requirements in `business-to-business' (B2B) markets and to present a new logistics service concept, where the traditional logistics service is expanded with significant manufacturing and value addedfacilities. The traditional third-party logistics service providers are not necessarily able to offer services, which cover widely the needs of potential customers. The study has been outlined to spare part markets in metal industry. In the second phase of the Valssi-project the aim is to examine the economical conditions and potentiality of the new logistics business concept. This research report (Part 1) concentrates on examining current trends in global and domestic logistics markets. Based on detailed survey among the participating companies, the study presents basis for a new logistics business concept model. The developed concept consists of 12 different service modules, which are split into deeper details of processes. The integration of worldwide supplier and service provider network together with customer companies systems is a challenge. The report focuses on evaluating the requirements for the new business concept from the customer-companies point of view. The study paints an overall picture of distribution and service provider network including an abstract about the software and system integration possibilities. As a result of the survey, it can be concluded that thereis need for the new business concept among the participating companies, and a modular service concept meets the requirements of them, because the new sophisticated concept considers the specialities involved in spare part logistics in metal industry.

Value added logistical support service: logistiikan palveluiden tarjoajat Suomessa. osa 4

Tämä osatutkimus on VALSSI- tutkimusprojektin (Value Added Logistical Support Service) neljäs osavaihe. VALSSI- tutkimuksen tarkoituksena on ollut selvittää logistiikkapalveluiden vaatimuksia business-to-business (B2B) ympäristössä ja määrittää logistiikkapalveluiden palvelukonsepti, jossa perinteiset logistiikkapalvelut on laajennettu tuotannollisilla ja lisäarvoa tuottavilla palveluilla. Tutkimuksen tarkoituksena on ollut tuottaa ulkoistamista helpottavaa materiaalia erityisesti varastoinnin ja kuljetusten osalta. Edellisistä osavaiheista on saatavilla tutkimusraportit yliopiston Internet-sivuilta(www.lut.fi/tutkimus/valore). Tämän tutkimuksen tarkoituksena oli kartoittaa Suomessa toimivien logistiikkapalveluyritysten palvelutarjonta. Tutkimus on keskittynyt palveluntarjoajiin, jotka tarjoavat erikoistunutta logistiikkaa (mm. tuotannollisia palveluita, hankintoja ja pakkauspalveluita) asiakkailleen. Tutkimukseen osallistuneet yritykset olivat suomalaisia ja kansainvälisiä sekä kuljetuspalveluita tarjoavia että logistiikkapalveluyrityksiä sekä alihankkijoina/tukkureina toimivia palveluntarjoajia. Huomionarvoista onkin, että moni yrityksistä käytti markkinoilta saatavia kuljetuspalveluita eikä toiminut itse kuljetusoperaattorina. Logistiikkapalveluyrityksissä huomattiin eroavaisuuksia asiakaspalvelun laajuudessa, ICT strategioissa, hankintojen ja kotiinkutsujen organisoinnissa, tuotannollisissa palveluissa sekä paluulogistiikassa. Varsinaiset varastointipalvelut ovat homogeenisia ja varastointiin liittyvät pakkaamispalvelut ovat pääasiassasamankaltaisia. Markkinoilla toimivien tukkukauppiaiden logistiikkaprosessit eroavat perinteisistä palveluntarjoajista. Tukkurit hoitavat laajasti mm. asiakaspalvelua, teknistä tukea sekä erikoistuneita tuotannollisia palveluita. Nykypäivänä asiakkaat asettavat enemmän vaatimuksia logistiikkapalveluyrityksen prosesseille ja prosessien johtamiselle. Tulevaisuudessa Suomessa ja maailmalla toimivat logistiikkapalveluyritykset tulevat toimimaan yhteistyöverkoissa Itä- Euroopan maat ovat entistä suuremmassa roolissa uusia jakelukanavia ja palveluita mietittäessä. Jo nyt on huomattavissa, että asiakkaat vaativat logistiikan palvelutarjoajia tarjoamaan entistä monipuolisempia ja tuotteistetumpia palveluita.

Value added logistical support service: logistics cost structure and performance in the new concept. Part 3

The aim of this study is to present an Activity-Based Costing spreadsheet tool for analyzing the logistics costs. The tool can be used both by customer-companies and logistics service providers. The study discusses the influence of different activity models on costs. Additionally this paper discusses about the logistical performance across the total supply chain This study is carried out using ananalytical research approach and literature material has been used for supplementing the concerned research approach. Cost structure analysis was based on the theory of activity-based management. This study was outlined to spare part logistics in machine-shop industry. The outlines of logistics services and logisticalperformance discussed in this report are based on the new logistics business concept (LMS-concept), which has been presented earlier in the Valssi-project. Oneof the aims of this study is to increase awareness of different activity modelson logistics costs. The report paints an overall picture about the business environment and requirements for the new logistics concept.

Value added logistics in supply and demand chains. Smile. Part 1. eBusiness between global company and itslocal sme supplier network

VALOSADE (Value Added Logistics in Supply and Demand Chains) is the research project of Anita Lukka's VALORE (Value Added Logistics Research) research team inLappeenranta University of Technology. VALOSADE is included in ELO (Ebusiness logistics) technology program of Tekes (Finnish Technology Agency). SMILE (SME-sector, Internet applications and Logistical Efficiency) is one of four subprojects of VALOSADE. SMILE research focuses on case network that is composed of small and medium sized mechanical maintenance service providers and global wood processing customers. Basic principle of SMILE study is communication and ebusiness insupply and demand network. This first phase of research concentrates on creating backgrounds for SMILE study and for ebusiness solutions of maintenance case network. The focus is on general trends of ebusiness in supply chains and networksof different industries; total ebusiness system architecture of company networks; ebusiness strategy of company network; information value chain; different factors, which influence on ebusiness solution of company network; and the correlation between ebusiness and competitive advantage. Literature, interviews and benchmarking were used as research methods in this qualitative case study. Networks and end-to-end supply chains are the organizational structures, which can add value for end customer. Information is one of the key factors in these decentralized structures. Because of decentralization of business, information is produced and used in different companies and in different information systems. Information refinement services are needed to manage information flows in company networksbetween different systems. Furthermore, some new solutions like network information systems are utilised in optimising network performance and in standardizingnetwork common processes. Some cases have however indicated, that utilization of ebusiness in decentralized business model is not always a necessity, but value-add of ICT must be defined case-specifically. In the theory part of report, different ebusiness and architecture models are introduced. These models are compared to empirical case data in research results. The biggest difference between theory and empirical data is that models are mainly developed for large-scale companies - not for SMEs. This is due to that implemented network ebusiness solutions are mainly large company centered. Genuine SME network centred ebusiness models are quite rare, and the study in that area has been few in number. Business relationships between customer and their SME suppliers are nowadays concentrated more on collaborative tactical and strategic initiatives besides transaction based operational initiatives. However, ebusiness systems are further mainly based on exchange of operational transactional data. Collaborative ebusiness solutions are in planning or pilot phase in most case companies. Furthermore, many ebusiness solutions are nowadays between two participants, but network and end-to-end supply chain transparency and information systems are quite rare. Transaction volumes, data formats, the types of exchanged information, information criticality,type and duration of business relationship, internal information systems of partners, processes and operation models (e.g. different ordering models) differ among network companies, and furthermore companies are at different stages on networking and ebusiness readiness. Because of former factors, different customer-supplier combinations in network must utilise totally different ebusiness architectures, technologies, systems and standards.

Value added logistics in supply and demand chain. Smile. Part 2. eBusiness in a service business. Case: A maintenance and operations network in forest industry

VVALOSADE is a research project of professor Anita Lukka's VALORE research team in the Lappeenranta University of Technology. The VALOSADE includes the ELO technology program of Tekes. SMILE is one of four subprojects of the VALOSADE. The SMILE study focuses on the case of the company network that is composed of small and micro-sized mechanical maintenance service providers and forest industry as large-scale customers. The basic principle of the SMILE study is the communication and ebusiness in supply and demand networks. The aim of the study is to develop ebusiness strategy, ebusiness model and e-processes among the SME local service providers, and onthe other hand, between the local service provider network and the forest industry customers in a maintenance and operations service business. A literature review, interviews and benchmarking are used as research methods in this qualitative case study. The first SMILE report, 'Ebusiness between Global Company and Its Local SME Supplier Network', concentrated on creating background for the SMILE study by studying general trends of ebusiness in supply chains and networks of different industries. This second phase of the study concentrates on case network background, such as business relationships, information systems and business objectives; core processes in maintenance and operations service network; development needs in communication among the network participants; and ICT solutions to respond needs in changing environment. In the theory part of the report, different ebusiness models and frameworks are introduced. Those models and frameworks are compared to empirical case data. From that analysis of the empirical data, therecommendations for the development of the network information system are derived. In process industry such as the forest industry, it is crucial to achieve a high level of operational efficiency and reliability, which sets up great requirements for maintenance and operations. Therefore, partnerships or strategic alliances are needed between the network participants. In partnerships and alliances, deep communication is important, and therefore the information systems in the network also are critical. Communication, coordination and collaboration will increase in the case network in the future, because network resources must be optimised to improve competitive capability of the forest industry customers and theefficiency of their service providers. At present, ebusiness systems are not usual in this maintenance network. A network information system among the forest industry customers and their local service providers actually is the only genuinenetwork information system in this total network. However, the utilisation of that system has been quite insignificant. The current system does not add value enough either to the customers or to the local service providers. At present, thenetwork information system is the infomediary that share static information forthe network partners. The network information system should be the transaction intermediary, which integrates internal processes of the network companies; the network information system, which provides common standardised processes for thelocal service providers; and the infomediary, which share static and dynamic information on right time, on right partner, on right costs, on right format and on right quality. This study provides recommendations how to develop this system in the future to add value to the network companies. Ebusiness scenarios, vision, objectives, strategies, application architecture, ebusiness model, core processes and development strategy must be considered when the network information system will be developed in the next development step. The core processes in the case network are demand/capacity management, customer/supplier relationship management, service delivery management, knowledge management and cash flow management. Most benefits from ebusiness solutions come from the electrifying of operational level processes, such as service delivery management and cash flow management.

Tehdaslogistiikka : value added logistics of the supply and demand chain costfix

VALOSADE (Value Added Logistics in Supply and Demand Chains) on Lappeenrannan teknillisen yliopiston ja sielläprofessori Anita Lukan VALORE -tutkimusryhmän toteuttama tutkimusprojekti, jonka rahoittaja on ollut Tekes. Projekti on osa Tekesin ELO - Elektronisen liiketoiminnan logistiikka - teknologiaohjelmaa. Tutkimusta rahoittivat Tekesin lisäksi neljä yritystä, jotka toimivat myös tutkimustyön kohteina ja toimivat tarpeen mukaan yhteistyössä tutkijoiden kanssa. Yritysten toimialat ovat metsäteollisuus, laitevalmistaja, joka tarjoaa myös tuotteilleen jälkimarkkinapalveluja sekä kaksi logistiikkapalveluyritystä. Tämä työraportti liittyy VALOSADE - tutkimusprojektin osaprojektiin Costfix (Paper Mill Process - from Fixed Costs into Variable Costs). Costfix - projektin tavoitteena on tutkia ja löytää paperiteollisuudelle uusia toimintamalleja, jotka mahdollistavat kiinteiden kustannusten muuttamisen muuttuviksi. Merkittävä tutkimuksen osa-alue on myös tutkimuskohteiden liike-toiminnan nykytilan aiempaa tarkempi selvittäminen. Tämä työraportti käsittelee kunnossapidon materiaalilogistiikan osalta tehtaan sisällä tapahtuvaa toimintaa, josta tässä tutkimuksessa käytetään nimitystä tehdaslogistiikka. Nykytilaselvityksen perusteella nykyinen prosessiteollisuudessa ja myös pääsääntöisesti valmistavassa teollisuudessa yleisesti vallitseva teollisuusyrityksen käyttöinvestointia ylläpitävän palveluprosessin toimintarakenne, johtamistapa ja prosessin operatiivisten tehtävien toimenkuvat eivät tue ko. palvelukokonaisuuden tehokasta ja tuloksellista toteuttamista. Nykymuotoinen toimintamalli pikemminkin rajoittaa toimintaprosessin kokonaishallintaa ja sen tehostamiseksi investoitujen uusien teknisten ratkaisujen ja teknologian käyttöönottoa. Lisäksi yleisesti vallitseva toimintakulttuuri (mm. arvokäsitykset, uskomukset sekä toiminnan ja tavoitteiden taustalla olevat motiivit) sekä vaikeuttaa nykyisen ja tulevan kilpailutilanteen edellyttämien tehokkuus- ja tuottavuustavoitteiden toteutumista että hidastaa uudistusten onnistumista edellyttävän muutoksen etenemistä yrityksen sisällä. Tutkimuksen tulokset vahvistivat osaltaan sen, että tehdas- ja toimintokeskeinen johtaminen aiheuttavat palveluprosessin eri tehtäville asetettujen tavoitteiden ja perustehtäväkäsityksen välille ristiriitoja, joista seuraa sekä suoria että välillisiä vaikutuksia teollisuusyrityksen tuotantoprosessin toiminnan laatuun ja tuotantolaitteiden käyttövarmuuteen. Palvelukokonaisuuteen kuuluvien eri toimintaprosessien tehtävät on jaettu ristiriitaisesti toiminnoille siten, että erityisestikunnossapidon teknisten toimihenkilöitten hoidettavana on sekä ihmisen henkilökohtaisen kapasiteettirajan ylittävä että toisistaan liian suuri erilaisia osaamisia ja ymmärrystä edellyttävä tehtävämäärä. Nykytilan palvelutuotannossa esiintyvien ongelmien seuraukset ja perussyyt osoittavat, että merkittävästi pääomia sitovan valmistavan teollisuuden (mm. prosessiteollisuus) käyttö-omaisuutta ylläpitävän palveluprosessin hallinta on ulkoistettava tehdastasolta itsenäisesti hoidettavaksi liiketoimintakokonaisuudeksi, jonka operatiivinen johtaminen tapahtuu toimintaprosesseittain konsernin ylätasolta käsin. Johtamismallissa painottuu prosessijohtaminen ja oman vastuualueen toimintaprosessin asiantuntemus. Lisäksi ihmisen osaamiseen, ymmärrykseen ja toimintatapaan perustuva palvelu edellyttää johtamiselta henkilöjohtamistaitoa ja osaamisen johtamista. Liiketoiminnan uudenlainen keskittyminen, verkostoituminen ja globalisoituminen edellyttävät johdoltamyös erilaisten toimintaverkostojen ja sidosryhmien toiminnan ja tarpeen ymmärtämistä. Tutkimustulosten perusteella myös palveluprosesseissa toimivien toimihenkilöitten tehtäväkuvia on muutettava radikaalisti ja osa uusista toimenkuvista edellyttää lisäksi henkilöitten osaamistason aktiivista parantamista. Tässä raportissa esitetään toimintamalli, jossa kuvataan tutkimuksen pohjalta luotu palvelukokonaisuuden johtamismalli ja palveluprosessien eri tehtävätasot tehtävineen. Kuvattu johtamismalli on ollut jo yleisesti käytössä yksittäisillä palvelualoilla, mutta tässä esitetty malli on valmistavan yrityksen teknisiin tukipalveluihin muokattu sovellus.

Value added logistical support service Part 2. Outsourcing process of spare part logistics in metal industry

The aim of this research study was to find out guidelines for outsourcing of logistics processes. The study was outlined to spare parts and `business-to-business' (B2B) markets in metal industry. This study can be applied as a manual for outsourcing especially warehousing and transportation activities. The study also touches other important areas of spare part logistics like manufacturing, customer service, procurement, quality control, reverse and recycling logistics, logistics technologies and valueadded services. The method of study consisted of three areas. Firstly exchanging views with logistics experts in participating companies, and secondly compiling material based on author's practical experience in logistics business with several international and domestic logistics service providers and vendors. Thirdlythe study includes also references to literature material. Due to the fact thatthe outsourcing of logistics functions can be handled widely and from differentpoint of views, in this study it is concentrated mainly on giving general levelguidelines for defining logistics strategy, hints both for tendering process and implementation project, and not forgetting the aftercare of business partnership.
