Improving strategic decision-making with simulation based decision support systems

Combating climate change is one of the key tasks of humanity in the 21st century. One of the leading causes is carbon dioxide emissions due to usage of fossil fuels. Renewable energy sources should be used instead of relying on oil, gas, and coal. In Finland a significant amount of energy is produced using wood. The usage of wood chips is expected to increase in the future significantly, over 60 %. The aim of this research is to improve understanding over the costs of wood chip supply chains. This is conducted by utilizing simulation as the main research method. The simulation model utilizes both agent-based modelling and discrete event simulation to imitate the wood chip supply chain. This thesis concentrates on the usage of simulation based decision support systems in strategic decision-making. The simulation model is part of a decision support system, which connects the simulation model to databases but also provides a graphical user interface for the decisionmaker. The main analysis conducted with the decision support system concentrates on comparing a traditional supply chain to a supply chain utilizing specialized containers. According to the analysis, the container supply chain is able to have smaller costs than the traditional supply chain. Also, a container supply chain can be more easily scaled up due to faster emptying operations. Initially the container operations would only supply part of the fuel needs of a power plant and it would complement the current supply chain. The model can be expanded to include intermodal supply chains as due to increased demand in the future there is not enough wood chips located close to current and future power plants.

Prepayments also play a significant role, particularly in project-based businesses. Developing companies´ working capital management requires knowledge from different kind of key operations´ in the company, like purchasing, production, sales, logistics and financing. The perspective to develop and describe working capital management is an operational. After literature reviews the thesis present pilot projects that formed the basis of a model to monitor working capital in the case company. Based on analysis and pilot projects, the thesis introduces a rough model for monitoring capital commitments in short time period. With the model the company can more efficiently monitor and manage their customer projects.

Käyttöpääoman sitoutuminen ja kiertoajat lääkejakeluketjussa

Työn tavoitteenaan oli selvittää suomalaisen lääkejakeluketjun rakenne sekä saada selkeä kuva ketjun toiminnan tehokkuudesta käyttöpääoman sitoutumisen ja kiertoaikojen osalta. Työn alussa käydään läpi teoriaa ja tutkimusta käyttöpääomasta ja sen erien kiertoajoista sekä erityisesti niiden huomioimisesta arvoketjussa. Lisäksi esitellään Suomen lääkemarkkinoiden toimintaa sekä sen toimijoita. Työn empiirinen osa suoritettiin kahdessa päävaiheessa. Ensin analysoitiin Voitto+ -ohjelmasta saatuja valittujen lääkejakeluketjun yritysten julkisia tilinpäätöstietoja ajalta 2005- 2011. Analysointi perustui käyttöpääoman sekä sen erien myyntisaamisten, ostovelkojen ja vaihto-omaisuuden kiertoaikojen laskemiseen. Ketjun yrityksiä vertailtiin toisiinsa ketjun osien keskimääräisten kiertoaikojen osalta ja saatiin selville niiden suhteellinen sijoittuminen toisiinsa nähden. Työn toisessa päävaiheessa haastateltiin esimerkkitoimijaa käsitellyn lääkejakeluketjun jokaisesta osasta: lääketehdas, tukkujakelija ja apteekki. Työssä huomattiin, että käyttöpääoman kiertoaikaan lääkejakeluketjussa vaikuttaa ensisijaisesti ketjun osan toiminnan luonne ja käyttöpääoman hallinnan tehokkuus lääkejakeluketjun toimijoiden välillä vaihtelee osaamisen ja resurssien mukaan. Ketjun eri osissa painottuvat eri käyttöpääoman erät ja ketjun toiminta on optimoitunut aikojen saatossa hyvin stabiiliin tilaan, jota ketjun jäsenillä ei näytä olevan halua muuttaa. Lääkejakeluketjun käyttöpääomaan hallintaa voitaisiin tehostaa varastonhallintaa parantamalla sekä informaation jakamisella saattamalla kysyntätiedot nopeammin koko ketjun tietoon.

Toimitusketjuun sitoutuvan pääoman hallinta keskisuuressa metalliteollisuusyrityksessä

Tämän diplomityön tavoitteena on tunnistaa kohdeyrityksen toimitusketjuun sitoutuvan pääoman lähteet ja niihin sitoutunut pääoma, menetelmät pääoman vapauttamiseksi sekä kehityskohteet toimitusketjuun sitoutuneen pääoman hallinnan näkökulmasta. Kes-keisimmät tutkitut pääoman lähteet ovat varastot ja keskeneräinen tuotanto, mutta myös ostovelkoja sekä rahtikustannuksia käsitellään. Varastoitavat nimikkeet jaettiin kahteen pääryhmään, ostettavat ja valmistettavat nimikkeet. Pääryhmät jaettiin edelleen pienem-piin alaryhmiin, nimiketyyppeihin, jotta analyysien tulokset voidaan kohdentaa tarkemmin. Varastoon sidotun pääoman kehityskohteiden tunnistamisessa käytettiin varastoarvoa, keskivarastoa ja kiertonopeutta, sekä näiden kombinaatioita. Tulokset esitettiin sekä pääryhmätasolla, että nimiketyyppitasolla, jotta kehityskohteet olisi helpompi tunnistaa. Keskeneräisen tuotannon osalta tavoitteena oli ensisijaisesti tunnistaa, kuinka suuri osa toimitusketjun pääomasta siihen sitoutuu. Rahtikustannukset tiedetään vuositasolla ja sen kautta on mahdollista arvioida kuukausittain rahteihin keskimäärin sitoutuva pääoma. Ostovelat on käsitelty vain kevyesti, koska se on itse asiassa käyttöpääoman erä. Keskeisimmät löydökset liittyvät kiertonopeuteen ja nimikkeiden ohjaustapaan. Osalla pääomaa varastoon sitovista nimikkeistä kiertonopeus on nolla ja useiden nimikkeiden kohdalla kiertonopeudessa on parannettavaa. Myös osa tilausohjautuvista nimikkeistä sitoo ennakko-odotuksista poiketen pääomaa varastoon. Kaikkiin edellä mainittuihin löy-döksiin tunnistettiin tilanteeseen johtaneet syyt ja määritettiin kehitystoimenpiteet, jotta tilanteet voidaan jatkossa välttää.

Agility in international fast fashion retailing

The birth of Internet technologies, the developments of fast fashion and multiple retailing channels have created a need for a new, more integrated way for doing retailing. Agility in fast fashion retailing could be seen as a significant way of responding to these changes and furthermore, as a way to respond to consumers’ altering demands. The purpose of this study was to explore the ways in which agile supply chains and integrated multichannel retailing influence the international fast fashion retailing. A framework for agility in retail was developed based on available theoretical considerations in distribution and communication channels. Qualitative research methods and qualitative content analysis were used. Four expert interviews were carried out to gain new perspectives to the objectives. The rest of the data was collected from an industry specific document, expert video and two expert lectures. Following the data collection, the research material was analyzed with qualitative content analysis. The empirical findings on agility in retail were presented based on a coding frame. It was found that agility in retail has multiple parts, which are overlapping and affecting one another. Furthermore, instead of viewing the agile supply chain and integrated multichannel retailing separately of each other as usual, it was found that they should be integrated, and the term “agility” was proposed to denote this approach. Also, it was found that the most common drivers and constrains of integrated multichannel retailing were the new Internet technologies and customer demand. Brick-and-mortar store, online store, mobile devices and social media were found to be the most common retailing channels. Furthermore, in-store technology, click-and-collect approach, NFC-buying, RFID-technology as well as 3D- digital simulations on fabrics and patterns will enhance agility even more in the future. In addition, environmental issues, customer experiences and communication will be important factors. This study has provided new practical insights for the future retailing. Furthermore, it has contributed to the academic research by discussing the traditional approaches of agility in fast fashion retail and bringing in new insights.

BIOTULI - Selvitys bioliiketoiminnan uusista liiketoimintamahdollisuuksista ja -malleista

Tämä raportti on osa BIOTULI-projektia, jossa tutkitaan biojalostamoiden uusia tuotteita ja liiketoimintamalleja. Raportin tavoitteena on selvittää, millaisilla liiketoimintamalleilla BIOTULI-projektissa löytyneitä potentiaalisia bioliiketoimintamahdollisuuksia pystytään hyödyntämään pk-yrityksen näkökulmasta. Tavoitteena on myös tutkia millaisen toimitusketjun liiketoimintamalli vaatii, ja millä edellytyksillä sen toteuttaminen on kannattavaa. Raportissa tarkastellaan torrefioinnin ja lämmöntuotannon yhdistämistä sekä BIOTULI-projektissa kehitetyn uuden erottelumenetelmän hyödyntämistä biohajoavan desinfiointiaineen valmistuksessa. Selvitystyö toteutettiin asiantuntijahaastatteluiden ja kirjallisuuskatsauksen perusteella. Molemmille casetapauksille muodostettiin liiketoimintamalli sekä arvioitiin sen toteutettavuutta ja kehitysnäkymiä. Torrefioinnin ja lämmöntuotannon yhdistäminen ei tehdyn analyysin perusteella ole tällä hetkellä kannattavaa, mutta muutokset markkinatilanteessa voivat muuttaa tilannetta tulevaisuudessa. Biohajoavan desinfiointiaineen valmistuksessa on potentiaalia kannattavaan liiketoimintaan, mutta tutkimus on vielä kesken, joten tarkkaa liiketoiminnan tai sen kannattavuuden arviointia ei vielä voi tehdä. Työn tuloksia voi käyttää pohjana tarkemmille kannattavuusarvioille.

Supply network risks and costs in Finnish project business

This report summarizes the results of the survey HAVERI – Supply network risks in business. The survey was conducted in Finland during the spring and summer of year 2013. The survey is part of a large two-year research project started in June 2012 in Finland (on-going 06/2012–07/2014). The project is launched and financed by TEKES, the Finnish Funding Agency for Technology and Innovation, and executed together with the researchers from Lappeenranta University of Technology and Tampere University of Technology. The overall goal of this on-going research project is to find out the decision-making practices in the project-oriented companies in their purchasing decisions especially in the mechanical engineering and construction industries in Finland. The objective of the survey was to gain cross-sectional data concerning the challenges, risks and cost factors in Finnish project business companies. The results show that Finnish companies rely on their experience and supplier references in their risk management. In general, the understanding of the total cost structure varies among the industries and companies. The main cost factor in risk management was costs before the actual purchase decision. Overall, it seems that the monetary value of the whole project and capability of purchasing personnel are the main influencing factors on risk management activity in project purchasing.

Networks and partnerships in third party logistics service production

Third party logistics, and third party logistics providers and the services they offer have grown substantially in the last twenty years. Even though there has been extensive research on third party logistics providers, and regular industry reviews within the logistics industry, a closer research in the area of partner selection and network models in the third party logistics industry is missing. The perspective taken in this study was of expanding the network research into logistics service providers as the focal firm in the network. The purpose of the study is to analyze partnerships and networks in the third party logistics industry in order to define how networks are utilized in third party logistics markets, what have been the reasons for the partnerships, and whether there are benefits for the third party logistics provider that can be achieved through building networks and partnerships. The theoretical framework of this study was formed based on common theories in studying networks and partnerships in accordance with models of horizontal and vertical partnerships. The theories applied to the framework and context of this study included the strategic network view and the resource-based view. Applying these two network theories to the position and networks of third party logistics providers in an industrial supply chain, a theoretical model for analyzing the horizontal and vertical partnerships where the TPL provider is in focus was structured. The empirical analysis of TPL partnerships consisted of a qualitative document analysis of 33 partnership examples involving companies present in the Finnish TPL markets. For the research, existing documents providing secondary data on types of partnerships, reasons for the partnerships, and outcomes of the partnerships were searched from available online sources. Findings of the study revealed that third party logistics providers are evident in horizontal and vertical interactions varying in geographical coverage and the depth and nature of the relationship. Partnership decisions were found to be made on resource based reasons, as well as from strategic aspects. The discovered results of the partnerships in this study included cost reduction and effectiveness in the partnerships for improving existing services. In addition in partnerships created for innovative service extension, differentiation, and creation of additional value were discovered to have emerged as results of the cooperation. It can be concluded that benefits and competitive advantage can be created through building partnerships in order to expand service offering and seeking synergies.

Supplier codes of conduct: Acting responsibly in global supply chains

Nowadays the Western companies are considered responsible for the social and environmental issues in their whole supply chains. To influence the practices of their suppliers the Western companies have created suppliers codes of conduct (SCCs) which express their requirements. Suppliers’ compliance with the SCCs is checked through audits. The purpose of this thesis is to analyze SCCs as a means for Western companies to ensure socially and environmentally responsible actions in their global supply chains, and the sub-objectives are to find out 1) how well do the SCCs and their auditing work at suppliers’ production sites and 2) how can possible problems related to SCCs and their auditing be solved. This is a qualitative research carried out in the form of a case study with two case companies. In this study both primary and secondary data is used. The primary data is collected in the form of interviews of the case company representatives and three external experts. Based on a theoretical framework of previous research in the fields of corporate social responsibility and supply chain management, a model with eleven factors, which influence the success of SCC implementation and the auditing of SCC –implementation, is drafted. Also several different best-practices to help to solve and avoid possible problems related to SCC -implementation and auditing have been identified from previous research. Based on the findings of this study the theoretical model has been updated adding two new influential factors. It seems that how well the SCC and its auditing work at suppliers’ production sites depends on the joint effect of thirteen influential factors: buyer’s purchasing policy, supplier’s motivation, buyer’s commitment, the solving of agency problems, the contents of the SCC, supplier’s role and the buyer-supplier –relationship, complexity of supply chain, the limitations of the smaller buyers, cooperation through a business association or multi-stakeholder system, the role of supplier’s employees, SCC –related communication and supplier’s understanding, cheating in audits and the auditors. The possible problems related to SCCs and their auditing can be solved by adopting best-practices. Nine of the theoretical best-practices stand out from the findings of this study: 1) two-way communication and collecting feedback from suppliers, 2) the philosophy of continuous improvement, 3) long-term business relationships with the supplier, 4) informing the supplier about the advantages of SCC –compliance, 5) rewarding code-compliant suppliers, 6) building collaborative, good buyer-supplier relationships, 7) supporting and advising the supplier, 8) joining a business association or multi-stakeholder system and 9) interviewing supplier’s employees as a part of the audits.

Developing of Supportive Context for Eco-Industrial Networks in Finland

The aim of the present thesis was to explore possible promotional actions to support the emergence of eco-industrial business networks in Finland. The main objectives were to investigate what kind of factors affect in the development of eco-industrial networks and further make suggestions in what kinds of actions this could be supported. In addition, since the active facilitation was discovered as one potential promoting activity, further investigation about facilitation process in Finnish context was conducted and also main characteristics of nationwide facilitation programme were identified. This thesis contains literature review of network orchestration and eco-industrial networks. The latter consists of green supply chain management and industrial symbiosis, although the main focus of the study leans on the concept of industrial symbiosis. The empirical data of the study was obtained from semi-structured expert interviews. These interviews were analyzed using qualitative content analysis. The study identified four main promotional activities for eco-industrial networks: 1) building awareness, 2) incentives, 3) dismantling of legislative barriers and 4) active facilitation. In addition, a framework for facilitation activities in Finnish context was built and main characteristics of nationwide facilitation programme were identified.

Toimitusketjun hallinnan erityispiirteet elintarvikepakkausalalla: lainsäädännön ja keskeisten standardien rooli

Tutkimuksen tavoitteena on kuvata elintarvikepakkausalan keskeisen lainsäädännön ja laadunhallintastandardien vaikutusta elintarvikepakkausalan toimitusketjujen hallinnassa. Tutkielmassa sovelletaan kvalitatiivista analyysitapaa ja tutkimus aineistona on kirjallinen materiaali sekä teemahaastattelu.Tutkielman teoreettinen viitekehys rakentuu toimitusketjun hallinnan ympärille.

Value of Information Logistics Integration in Digital Business Ecosystem

Digital business ecosystems (DBE) are becoming an increasingly popular concept for modelling and building distributed systems in heterogeneous, decentralized and open environments. Information- and communication technology (ICT) enabled business solutions have created an opportunity for automated business relations and transactions. The deployment of ICT in business-to-business (B2B) integration seeks to improve competitiveness by establishing real-time information and offering better information visibility to business ecosystem actors. The products, components and raw material flows in supply chains are traditionally studied in logistics research. In this study, we expand the research to cover the processes parallel to the service and information flows as information logistics integration. In this thesis, we show how better integration and automation of information flows enhance the speed of processes and, thus, provide cost savings and other benefits for organizations. Investments in DBE are intended to add value through business automation and are key decisions in building up information logistics integration. Business solutions that build on automation are important sources of value in networks that promote and support business relations and transactions. Value is created through improved productivity and effectiveness when new, more efficient collaboration methods are discovered and integrated into DBE. Organizations, business networks and collaborations, even with competitors, form DBE in which information logistics integration has a significant role as a value driver. However, traditional economic and computing theories do not focus on digital business ecosystems as a separate form of organization, and they do not provide conceptual frameworks that can be used to explore digital business ecosystems as value drivers—combined internal management and external coordination mechanisms for information logistics integration are not the current practice of a company’s strategic process. In this thesis, we have developed and tested a framework to explore the digital business ecosystems developed and a coordination model for digital business ecosystem integration; moreover, we have analysed the value of information logistics integration. The research is based on a case study and on mixed methods, in which we use the Delphi method and Internetbased tools for idea generation and development. We conducted many interviews with key experts, which we recoded, transcribed and coded to find success factors. Qualitative analyses were based on a Monte Carlo simulation, which sought cost savings, and Real Option Valuation, which sought an optimal investment program for the ecosystem level. This study provides valuable knowledge regarding information logistics integration by utilizing a suitable business process information model for collaboration. An information model is based on the business process scenarios and on detailed transactions for the mapping and automation of product, service and information flows. The research results illustrate the current cap of understanding information logistics integration in a digital business ecosystem. Based on success factors, we were able to illustrate how specific coordination mechanisms related to network management and orchestration could be designed. We also pointed out the potential of information logistics integration in value creation. With the help of global standardization experts, we utilized the design of the core information model for B2B integration. We built this quantitative analysis by using the Monte Carlo-based simulation model and the Real Option Value model. This research covers relevant new research disciplines, such as information logistics integration and digital business ecosystems, in which the current literature needs to be improved. This research was executed by high-level experts and managers responsible for global business network B2B integration. However, the research was dominated by one industry domain, and therefore a more comprehensive exploration should be undertaken to cover a larger population of business sectors. Based on this research, the new quantitative survey could provide new possibilities to examine information logistics integration in digital business ecosystems. The value activities indicate that further studies should continue, especially with regard to the collaboration issues on integration, focusing on a user-centric approach. We should better understand how real-time information supports customer value creation by imbedding the information into the lifetime value of products and services. The aim of this research was to build competitive advantage through B2B integration to support a real-time economy. For practitioners, this research created several tools and concepts to improve value activities, information logistics integration design and management and orchestration models. Based on the results, the companies were able to better understand the formulation of the digital business ecosystem and the importance of joint efforts in collaboration. However, the challenge of incorporating this new knowledge into strategic processes in a multi-stakeholder environment remains. This challenge has been noted, and new projects have been established in pursuit of a real-time economy.

Linking supplier delivery risk to outbound delivery service performance improvement

Customer satisfaction should be the main focus for all of the parts of the business. Usually supply chain behind the business is in a key role when this focus is pursued especially in repair service business. When focusing on the materials that are needed to make repairs to equipment under service contracts, the time aspect of quality is critical. Do late deliveries from supplier have an effect on the service performance of repairs when distribution center of a centralized purchasing unit is acting as a buffer between suppliers and repair service business? And if so, how should the improvement efforts be prioritized? These are the two main questions that this thesis focuses on. Correlation and linear regression was tested between service levels of supplier and distribution center. Percentage of on-time deliveries were compared to outbound delivery service level. It was found that there is statistically significant correlation between inbound and outbound operations success. The other main question of the thesis, improvement prioritization, was answered by creating material availability based supplier classification and additional to that, by developing the decision process for the analysis of most critical suppliers. This was built on a basis of previous supplier and material classification methods.
