Modeling and Simulation ofReal-Time System as a Tool to Improve Capacity Management - Case Fenix

Tämän tutkimustyön kohteena on TietoEnator Oy:n kehittämän Fenix-tietojärjestelmän kapasiteettitarpeen ennustaminen. Työn tavoitteena on tutustua Fenix-järjestelmän eri osa-alueisiin, löytää tapa eritellä ja mallintaa eri osa-alueiden vaikutus järjestelmän kuormitukseen ja selvittää alustavasti mitkä parametrit vaikuttavat kyseisten osa-alueiden luomaan kuormitukseen. Osa tätä työtä on tutkia eri vaihtoehtoja simuloinnille ja selvittää eri vaihtoehtojen soveltuvuus monimutkaisten järjestelmien mallintamiseen. Kerätyn tiedon pohjaltaluodaan järjestelmäntietovaraston kuormitusta kuvaava simulaatiomalli. Hyödyntämällä mallista saatua tietoa ja tuotantojärjestelmästä mitattua tietoa mallia kehitetään vastaamaan yhä lähemmin todellisen järjestelmän toimintaa. Mallista tarkastellaan esimerkiksi simuloitua järjestelmäkuormaa ja jonojen käyttäytymistä. Tuotantojärjestelmästä mitataan eri kuormalähteiden käytösmuutoksia esimerkiksi käyttäjämäärän ja kellonajan suhteessa. Tämän työn tulosten on tarkoitus toimia pohjana myöhemmin tehtävälle jatkotutkimukselle, jossa osa-alueiden parametrisointia tarkennetaan lisää, mallin kykyä kuvata todellista järjestelmää tehostetaanja mallin laajuutta kasvatetaan.

The effects of congestion in the daily management of a trauma hospital

Today’s healthcare organizations are under constant pressure for change, as hospitals should be able to offer their patients the best possible medical care with limited resources and, at the same time, to retain steady efficiency level in their operation. This is challenging, especially in trauma hospitals, in which the variation in the patient cases and volumes is relatively high. Furthermore, the trauma patient's care requires plenty of resources as most the patients have to be treated as single cases. Occasionally, the sudden increases in demand causes congestion in the operations of the hospital, which in Töölö hospital appears as an increase in the surgery waiting times within the yellow urgency class patients. An increase in the surgery waiting times may cause the diminution of the patient's condition, which also raises the surgery risks. The congestion itself causes overloading of the hospital capacity and staff. The aim of this master’s thesis is to introduce the factors contributing to the trauma process, and to examine the correlation between the different variables and the lengthened surgery waiting times. The results of this study are based on a three-year patient data and different quantitative analysis. Based on the analysis, a daily usable indicator was created in order to support the decision making in the operations management. By using the selected indicator, the effects of congestion can be acknowledged and the corrective action can also be taken more proactively.

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.

Newsprint Demand and Supply Scenarios

Diplomityön tavoitteena oli sanomalehtipaperin kysyntään ja tarjontaan vaikuttavien tekijöiden identifiointi ja analysointi. Nämä tekijät käytiin yhteisesti läpi skenaarioiden avulla. Aluksi kuvattiin teollisuuden ala ja esiteltiin tärkeimmät alaa kuvaavat mittarit. Analyysi tehtiin Porterin kilpailuteorian tekijöiden pohjalta. Työssä listattiin yksittäiset tekijät, jotka vaikuttavat sanomalehtipaperin kysyntään ja tarjontaan. Näistä tekijöistä valittiin tärkeimmät ja niiden pohjalta rakennettiin skenaarioita. Skenaariot kuvaavat erilaisia mahdollisia tulevaisuuksia.Kysyntä kuten myös tarjonta on jakautunut epätasaisesti maailmassa. Alueelliset erot ovat hyvinkin merkittäviä. Tästä johtuu laajamittainen kaupankäynti eri alueiden välillä. Käynnissä oleva paperiteollisuuden konsolidoitumisprosessi auttaa vähentämään sanomalehtipaperin hinnan ja tarjonnan heilahtelua. Tämä puolestaan johtuu alan keskittymisestä ja järkevästä kapasiteetin hallinnasta.Diplomityö korostaa sanomalehtipaperin tuottajien vastuuta tarjonnan lisäämisessä. E-median uhkaa tai mahdollisuutta on myös spekuloitu ja kysynnän alueellisen kysynnän kehitystä on analysoitu. Diplomityö antaa ehdotuksia erilaisiksi tulevaisuuden kehitysvaihtoehdoiksi. Sanomalehtipaperin kysyntä tulee kasvamaan maailmanlaajuisesti, tuotanto tulee siirtymään lähemmäksi markkinoita, kaupankäynti Aasiaan tulee kasvamaan ja yrityksen tulevat keskittymään viisaaseen kapasiteetin hallintaan.

Sairaalan kolmen yksikön kapasiteetin käytön kehittäminen

Tässä tutkimuksessa selvitettiin Etelä-Karjalan keskussairaalan sädehoitoyksikön, päiväkirurgisen yksikön sekä synnytysten ja naistentautien yksikön käyttämän kapasiteetin kustannuksia eri käyttöasteilla. Yksiköiden toiminta ja niiden keskeiset resurssit kuvattiin. Tiedot kerättiin käyttäen haastatteluja, käyttöomaisuuskirjanpitoa ja laskentatoimen talousraportointijärjestelmää. Yksiköiden tuloslaskelmien perusteella arvioitiin niiden muuttuvia ja kiinteitä kustannuksia. Kapasiteettimalleja arvioitiin voitavan hyödyntää esimerkiksi toiminnan seurannassa, suunnittelussa ja tavoiteasetannassa. Kapasiteetin määrittely ja kapasiteetin kustannusten laskenta erilaisille kapasiteetin käyttöasteille onnistui kaikissa yksiköissä. Parhaiten kapasiteetin kustannustieto kuvasi sädehoitoa ja heikoiten synnytyksiä. Käyttämätöntä kapasiteettia tunnistettiin sädehoitoyksikössä ja päiväkirurgisessa yksikössä. Toiminta-asteen noston vaikutukset yksikkökustannuksiin laskettiin kaikissa yksiköissä ja niissä yksiköissä, joissa oli käyttämätöntä kapasiteettia, tehtiin lisäksi tarkempia laskelmia ja ehdotuksia toiminnan kehittämiseksi.

Fenestra Oy:n tuotekustannuslaskennan kehittäminen – Case oviteollisuus

Kilpailluilla markkinoilla menestyäkseen yrityksen tulee tuntea oman tuotannon kustannusrakenne. Yrityksen täytyy menestyäkseen tarjota asiakkaalle yksilöllisiä tuotteita kilpailukykyiseen hintaan. Tämä aiheuttaa haasteita tuotannolle, mutta myös tuotekustannuslaskennalle; perinteisin tuotekustannuslaskentamenetelmin ei enää pystytä huomioimaan laajan tuotevalikoiman tuotteiden valmistuksen eroavaisuuksia. Tämän diplomityön tarkoituksena on selvittää Fenestra Oy:n tuotekustannuslaskentakäytäntöjen soveltuvuus nykyhetkeen. Vertailukohdaksi työssä määritellään vaihtoehtoinen laskentamalli tuotekustannusten laskemiseksi. Uuden laskentamallin soveltuvuutta käytäntöön tutkitaan esimerkkilaskelmin, joiden tuloksia verrataan Fenestra Oy:n nykyisen laskennan tuloksiin. Laskentamallilla aikaansaadut tulokset poikkeavat Fenestra Oy:n nykyisestä laskennasta ennakoidulla tavalla; perinteisin menetelmin valmistukseltaan yksinkertaisille tuotteille kohdistuu liikaa kustannuksia ja monimutkaisille liian vähän. Laadittu laskentamalli on diplomityön laajuuden puitteessa varsin yksinkertainen, mutta suuntaa-antava. Jatkokehityskohteena laskennan kehittämiseksi tuotannosta tulisi alkaa kerätä tarkemmin tietoa ja materiaalikäytön osalta tarkkaa hukkaselvitystä.

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.

Tulosyksikkölaskentamallin kehittäminen teollisuusyrityksen ohjauksen välineeksi

Tämän diplomityön kohdeyrityksenä toimii prosessijohtamismallin mukaisesti organisoitunut sellua valmistava ja toimittava yritys. Yritys valmistaa omaa sellua neljällä tehtaalla, jotka sijaitsevat eri paikkakunnilla. Tulosyksikkölaskentaa kehittämällä yritys haluaa tuoda esiin tehtaiden oman toiminnan merkityksen myös prosessijohtamisen toimintamallia noudatettaessa ja saada selville tehtaiden todellisen suorituksen tason. Tutkimusotteeltaan työ on konstruktiivinen, mutta siinä voidaan havaita piirteitä myös toiminta-analyyttisesta tutkimusotteesta. Työn tavoitteena oli kehittää kohdeyrityksen käyttöön yksinkertainen, selkeä ja helppokäyttöinen laskentamalli, jonka avulla yrityksen on mahdollista tarkastella ja vertailla eri tehtaiden tuotantoprosessien toiminnan tehokkuutta sekä sen kehitystä. Mallin rakentaminen perustui ohjattavuuden periaatteeseen pohjautuvaan vastuualuelaskentaan. Lisäksi mallin kehittämisessä hyödynnettiin benchmarkingin ja kapasiteettitarkastelun ajatuksia. Mallintamisen lähtökohtia selvitettiin kohdeyrityksen henkilöstön kanssa suoritettujen teemahaastattelujen avulla. Työn merkittävimpänä tuloksena syntyi teoreettisen aineiston, haastatteluihin perustuvan kvalitatiivisen tiedon sekä yrityksen tietojärjestelmistä saatavan datan avulla luotu laskentamalli. Mallin toimintaa tarkasteltiin sijoittamalla malliin tietyltä ajanjaksolta kerättyä numeerista aineistoa. Mallin avulla yrityksen on mahdollista aiempaa paremmin tarkastella eri tehtaiden onnistumista tuotantotoiminnassaan. Mallissa korostettiin, että tehtaiden on pystyttävä hallitsemaan omat erityispiirteensä, minkä vuoksi mallin antamia tuloksia tarkasteltaessa on huomioitava myös mahdolliset mallintamisen taustalla vaikuttavat tekijät. Mallintamisen lopputuloksena syntynyt selkeä perusmalli luo hyvät lähtökohdat myös mahdolliselle jatkokehitykselle.

On the innovation capacity of technologyrelated knowledge-intensive business services. A case study of the technology and engineering consulting (TEC) sector in Singapore

Even though the research on innovation in services has expanded remarkably especially during the past two decades, there is still a need to increase understanding on the special characteristics of service innovation. In addition to studying innovation in service companies and industries, research has also recently focused more on services in innovation, as especially the significance of so-called knowledge intensive business services (KIBS) for the competitive edge of their clients, othercompanies, regions and even nations has been proved in several previous studies. This study focuses on studying technology-based KIBS firms, and technology andengineering consulting (TEC) sector in particular. These firms have multiple roles in innovation systems, and thus, there is also a need for in-depth studies that increase knowledge about the types and dimensions of service innovations as well as underlying mechanisms and procedures which make the innovations successful. The main aim of this study is to generate new knowledge in the fragmented research field of service innovation management by recognizing the different typesof innovations in TEC services and some of the enablers of and barriers to innovation capacity in the field, especially from the knowledge management perspective. The study also aims to shed light on some of the existing routines and new constructions needed for enhancing service innovation and knowledge processing activities in KIBS companies of the TEC sector. The main samples of data in this research include literature reviews and public data sources, and a qualitative research approach with exploratory case studies conducted with the help of the interviews at technology consulting companies in Singapore in 2006. These complement the qualitative interview data gathered previously in Finland during a larger research project in the years 2004-2005. The data is also supplemented by a survey conducted in Singapore. The respondents for the survey by Tan (2007) were technology consulting companies who operate in the Singapore region. The purpose ofthe quantitative part of the study was to validate and further examine specificaspects such as the influence of knowledge management activities on innovativeness and different types of service innovations, in which the technology consultancies are involved. Singapore is known as a South-east Asian knowledge hub and is thus a significant research area where several multinational knowledge-intensive service firms operate. Typically, the service innovations identified in the studied TEC firms were formed by several dimensions of innovations. In addition to technological aspects, innovations were, for instance, related to new client interfaces and service delivery processes. The main enablers of and barriers to innovation seem to be partly similar in Singaporean firms as compared to the earlier study of Finnish TEC firms. Empirical studies also brought forth the significance of various sources of knowledge and knowledge processing activities as themain driving forces of service innovation in technology-related KIBS firms. A framework was also developed to study the effect of knowledge processing capabilities as well as some moderators on the innovativeness of TEC firms. Especially efficient knowledge acquisition and environmental dynamism seem to influence the innovativeness of TEC firms positively. The results of the study also contributeto the present service innovation literature by focusing more on 'innovation within KIBs' rather than 'innovation through KIBS', which has been the typical viewpoint stressed in the previous literature. Additionally, the study provides several possibilities for further research.

Competence Development and Capacity Building of Sawmill Enterprises in Kenya – A Human Resources Development Approach

The Kenyan forestry and sawmilling industry have been subject to a changing environment since 1999 when the industrial forest plantations were closed down. This has lowered raw material supply and it has affected and reduced the sawmill operations and the viability of the sawmill enterprises. The capacity of the 276 registered sawmills is not sufficient to fulfill sawn timber demand in Kenya. This is because of the technological degradation and lack of a qualified labor force, which were caused because of non-existent sawmilling education and further training in Kenya. Lack of competent sawmill workers has led to low raw material recovery, under utilization of resources and loss of employment. The objective of the work was to suggest models, methods and approaches for the competence and capacity development of the Kenyan sawmilling industry, sawmills and their workers. A nationwide field survey, interviews, questionnaire and literature review was used for data collection to find out the sawmills’ competence development areas and to suggest models and methods for their capacity building. The sampling frame included 22 sawmills that represented 72,5% of all the registered sawmills in Kenya. The results confirmed that the sawmills’ technological level was backwards, productivity low, raw material recovery unacceptable and workers’ professional education low. The future challenges will be how to establish the sawmills’ capacity building and workers’ competence development. Sawmilling industry development requires various actions through new development models and approaches. Activities should be started for technological development and workers’ competence development. This requires re-starting of vocational training in sawmilling and the establishment of more effective co-operation between the sawmills and their stakeholder groups. In competence development the Enterprise Competence Management Model of Nurminen (2007) can be used, whereas the best training model and approach would be a practically oriented learning at work model in which the short courses, technical assistance and extension services would be the key functions.

The role of alliance capabilities in alliance portfolio management

The question of why some firms perform better in managing their alliances has raised interest among scholars and managers. Whereas inter-firm factors influencing the alliance performance such as strategic fit between partners and the existence of complementarities have been studied extensively, research on firm-level antecedents is rather scarce. Therefore this study investigates the role of firm’s alliance capability in the alliance success equation. Particularly it analyses the specialized mechanisms and processes set up by firm in order to facilitate alliancerelated know-how leverage organization-wise. Evidence from a cross-industry sample of R&D intensive Finnish companies supports the fact that firms which have invested in institutionalizing alliance capabilities outperform their counterparts in alliance portfolio management. Results also suggest that firms need to adjust alliance management tools depending on the alliance portfolio size, prior experience with inter-firm partnerships and the strategic importance of alliances. Furthermore, absorptive capacity is found to be crucial for successful alliance management, its role being complementary to that of alliance capability. Finally, firms that have successful alliances also enjoy higher financial, market and innovation performance.

Supply management capability

The objective of this thesis is to define supply management capability. The thesis study what factors consist of supply management capability, and which of those factors are critical to achieving competitive advantage. One objective is also to study how firms can measure their supply management capability. This study is a qualitative research. The thesis examines the literature regarding to supply management and the context of capability and there are used Delphi panel to examine the current and future insights of supply management professionals concerning of supply management skills and capability. The empirical data of the thesis was collected by interviews. The Delphi panel was used in data collection and analysis and for prioritization of the factors of supply management capability. The thesis includes lists of factors of supply management capability. Main findings of the study were that there is no one clear, generally suitable set of supply management skills which bring competitive advantage for all firms and the most important factors of supply management capability, according to the experts, are total cost analysis, customer focus, general business view, market knowledge and supplier relationships. In this study the supply management capability is defined as organization’s overall capacity and ability to achieve a holistic understanding of purchasing needs, manage its suppliers and collaborative partners, and conduct its internal tasks, routines and responsibilities in a way that achieves desired results. The results of this thesis show also that Finnish firms need more right kind of supply management knowledge.

Absorptive capacity of Multinational Corporation’s parent company

The objective of this paper is to contribute to the literature concerning absorptive capacity by revealing the factors affecting the absorptive capacity of MNC parent company toward subsidiary and most particularly the effects of intra-organizational antecedents. The theoretical framework is build around previous findings on knowledge sharing and absorptive capacity. The empirical part of the study is a qualitative research which includes in-depth interviews and analysis of secondary data based on a single case company. The results showed that organizational structure, internal communication, informal networks, formal networks, internationalization, human resources management, shared language, meetings, trust, participation in decision-making, level of awareness, IT system, level of adaptation to market specifications and job rotation influence parent company’s absorptive capacity. Moreover, related problems to these antecedents have been identified. Additionally, recommendations to solve these problems are formulated. In the end, directions for future research on this topic are given.

Cross-border transmission capacity development – Experiences from the Nordic electricity markets

The liberalisation of the wholesale electricity markets has been considered an efficient way to organise the markets. In Europe, the target is to liberalise and integrate the common European electricity markets. However, insufficient transmission capacity between the market areas hampers the integration, and therefore, new investments are required. Again, massive transmission capacity investments are not usually easy to carry through. This doctoral dissertation aims at elaborating on critical determinants required to deliver the necessary transmission capacity investments. The Nordic electricity market is used as an illustrative example. This study suggests that changes in the governance structure have affected the delivery of Nordic cross-border investments. In addition, the impacts of not fully delivered investments are studied in this doctoral dissertation. An insufficient transmission network can degrade the market uniformity and may also cause a need to split the market into smaller submarkets. This may have financial impacts on market actors when the targeted efficient sharing of resources is not met and even encourage gaming. The research methods applied in this doctoral dissertation are mainly empirical ranging from a Delphi study to case studies and numerical calculations.
