With the airline industry experiencing a global economic downturn, B2B e-Business is becoming more and more the focus of airlines’ strategies. More recently, airlines have studied intensively the potential of joint-procurement possibilities and have taken measures in creating consortia-led B2B e-Marketplaces as mediators for aggregating demand and to facilitate transactions. In academic literature, limited academic research has been undertaken in exploring the value creation of B2B e-Marketplace models in the aviation industry. The aim is to conduct a theoretical analysis to explore whether or not e-Marketplaces have the potential to add value to procurement in the aviation industry. The research focuses on the potential of B2B e-Marketplaces in terms of improving an airline’s competitiveness in its procurement value chain. The theoretical framework adopted supports the identification of barriers to success and critical success factors.

The international economic and business environment continues to develop at a rapid rate. Increasing interactions between economies, particularly between Europe and Asia, has raised many important issues regarding transport infrastructure, logistics and broader supply chain management. The potential exists to further stimulate trade provided that these issues are addressed in a logical and systematic manner. However, if this potential is to be realised in practice there is a need to re-evaluate current supply chain configurations. A mismatch currently exists between the technological capability and the supply chain or logistical reality. This mismatch has sharpened the focus on the need for robust approaches to supply chain re-engineering. Traditional approaches to business re-engineering have been based on manufacturing systems engineering and business process management. A recognition that all companies exist as part of bigger supply chains has fundamentally changed the focus of re-engineering. Inefficiencies anywhere in a supply chain result in the chain as a whole being unable to reach its true competitive potential. This reality, combined with the potentially radical impact on business and supply chain architectures of the technologies associated with electronic business, requires organisations to adopt innovative approaches to supply chain analysis and re-design. This paper introduces a systems approach to supply chain re-engineering which is aimed at addressing the challenges which the evolving business environment brings with it. The approach, which is based on work with a variety of both conventional and electronic supply chains, comprises underpinning principles, a methodology and guidelines on good working practice, as well as a suite of tools and techniques. The adoption of approaches such as that outlined in this paper helps to ensure that robust supply chains are designed and implemented in practice. This facilitates an integrated approach, with involvement of all key stakeholders throughout the design process.

Recent years have seen innovations in the logistics and freight transport industry in relation to Information and communication technologies (ICT) diffusion. The implementation of such technologies by third party logistics providers (3PLs) allows the real-time exchange of information between supply chain partners, thereby improving planning capability and customer service. However, the logistics and freight transport industry is lagging somewhat behind other sectors in ICT diffusion. In relation to the latter point, it is important to note that the dissemination of ICT in logistics and supply chain management (SCM) is shifting the 3PL industry to an increasingly knowledge-intensive approach. In this process, the role of learning becomes more central and an assessment of the impact of future ICT learning needs for the logistics providers is a strategic imperative. The aim of this paper is to assess the impact of ICT on logistics and freight transport industry in Italy and Ireland, and to identify learning needs for more effective ICT adoption in 3PLs.

Supply chain formation (SCF) is the process of determining the set of participants and exchange relationships within a network with the goal of setting up a supply chain that meets some predefined social objective. Many proposed solutions for the SCF problem rely on centralized computation, which presents a single point of failure and can also lead to problems with scalability. Decentralized techniques that aid supply chain emergence offer a more robust and scalable approach by allowing participants to deliberate between themselves about the structure of the optimal supply chain. Current decentralized supply chain emergence mechanisms are only able to deal with simplistic scenarios in which goods are produced and traded in single units only and without taking into account production capacities or input-output ratios other than 1:1. In this paper, we demonstrate the performance of a graphical inference technique, max-sum loopy belief propagation (LBP), in a complex multiunit unit supply chain emergence scenario which models additional constraints such as production capacities and input-to-output ratios. We also provide results demonstrating the performance of LBP in dynamic environments, where the properties and composition of participants are altered as the algorithm is running. Our results suggest that max-sum LBP produces consistently strong solutions on a variety of network structures in a multiunit problem scenario, and that performance tends not to be affected by on-the-fly changes to the properties or composition of participants.

Purpose: To define a research agenda for creating Resource-Efficient Supply Chains (RESC) by identifying and analysing their key characteristics as well as future research opportunities. Design/methodology/approach: We follow a systematic review method to analyse the literature and to understand RESC taking a substantive theory approach. Our approach is grounded in a specific domain, the agri-food sector, because it is an intensive user of an extensive range of resources. Findings: The review shows that literature has looked at the use of resources primarily from the environmental impact perspective. It shows a lack of understanding of the specific RESC characteristics, and concludes more research is needed on multi-disciplinary methods for resource use and impact analyses as well as assessment methods for resource sensitivity and responsiveness. There is a need to explore whether or not, and how, logistics/supply chain decisions will affect the overall configuration of future food supply chains in an era of resource scarcity and depletion and what the trade-offs will be. Research limitations/implications: The paper proposes an agenda for future research in the area of resource–efficient supply chain. The framework proposed along with the key characteristics identified for RESC can be applied to other sectors. Practical implications: Our research should facilitate further understanding of the implications and trade-offs of supply chain decisions taken on the use of resources by supply chain managers. Originality/value: The paper explores the interaction between supply chains and natural resources and also defines the key characteristics of RESC.

This research aims at assessing the environmental impact of the poultry supply chain from cradle to grave using case study research and also life cycle assessment (LCA). While a limited number of generic poultry production LCA studies have been published, fewer yet assess the whole process of a specific organisation, none comparing the increased impact of further processing. Our results show that irrespectively of the impact assessment method utilised, the process of producing portions is considerably higher in total environmental impact due to the extra raw material required to produce the same mass into retail. Our research contributes to the growing number of LCA studies and could be used by practitioners for comparison against national and international averages. From a theoretical point of view, this research provides new insights into the relationship between vertically integrated supply chains and environmental performance which has not been examined in the past.

In this paper the issues of Ukrainian new three-level pension system are discussed. First, the paper presents the mathematical model that allows calculating the optimal size of contributions to the non-state pension fund. Next, the non-state pension fund chooses an Asset Management Company. To do so it is proposed to use an approach based on Kohonen networks to classify asset management companies that work in Ukrainian market. Further, when the asset management company is chosen, it receives the pension contributions of the participants of the non-pension fund. Asset Management Company has to invest these contributions profitably. This paper proposes an approach for choosing the most profitable investment project using decision trees. The new pension system has been lawfully ratified only four years ago and is still developing, that is why this paper is very important.

Industry practitioners are seeking to create optimal logistics networks through more efficient decision-making leading to a shift of power from a centralized position to a more decentralized approach. This has led to researchers, exploring with vigor, the application of agent based modeling (ABM) in supply chains and more recently, its impact on decision-making. This paper investigates reasons for the shift to decentralized decision-making and the impact on supply chains. Effective decentralization of decision-making with ABM and hybrid modeling is investigated, observing the methods and potential of achieving optimality.

This chapter investigates the resistance by institutional actors in ambiguous supply chain environments for online grocery provision. Recent studies have shown that significant shifts in urban geographies are increasing consumers' expectations of online retail provision. However, at the same time there is also growing evidence that the collaborative practice in online grocery provision within the urban supply chains is resisted. That these trends are found despite growing demand of online provision highlights both the difficulty of bringing geographically dispersed supply partners together and the problems associated with operating within and across ambiguous environments. Drawing upon twenty-nine in-depth interviews with a range of institutional actors, including retail, logistics, and urban planning experts within an urban metropolis in an emerging market, we detail the different ways that collaboration is resisted in online retail provision. Several different patterns of resistance were identified in (non-) collaboration notably, ideological, functional, regulatory and spatial. © 2011, IGI Global. C.

A lean menedzsment az értékteremtő folyamatok stratégiai és operatív szintjének meghatározó formálójává vált az elmúlt évtizedekben. Jelen tanulmány stratégiai nézőpontból tárgyalja a lean menedzsment teljes bevezetését. Részletes áttekintést ad a Womack és Jones (2003) által lefektetett lean alapelvekről. Az operatív teljesítményjavulásból származó vevői értékteremtés mellett foglalkozik a tulajdonosi értékteremtéssel, az MRP és a lean szinergikus összekapcsolásával, valamint a lean ideális szervezeti környezetével is. A lean a kapcsolódó területek illesztését is megköveteli, a műhelytanulmány röviden kitér az emberi erőforrás, a teljesítménymérés, az ellátási lánc és a termékfejlesztés legfontosabb kérdéseire. = Lean management has become the dominant strategic and operative framework of value creating processes in the last decades. The working paper describes the strategic approach of full lean implementation. It is mainly built on Womack and Jones’s (2003) lean principles. Beside the five lean principles the study is concerned with customer and shareholder value creation, touches upon the relationship of lean and MRP, and describes ideal lean organizational environment. Lean redesigns value creating processes and requires functional fit of related departments, so the most important issues of human resource, performance, supply chain management and product design are discussed as well.

Az elmúlt évtizedekben a gazdálkodástudomány kitüntetett figyelemmel kísért két - mind a makrogazdaság, mind az egyes vállalatok működésének sikere szempontjából meghatározó fontosságú - jelenséget, egyrészt a szolgáltatásoknak a hagyományos termeléssel szembeni egyre erőteljesebb térnyerését, másrészt a fogyasztói érték teremtése szempontjából növekvő jelentőségű ellátási láncoknak, illetve azok menedzsmentjének kérdéskörét. Ugyanakkor igen kevés elemzés, de kevés leíró jellegű munka is született a két jelenséget és menedzsment problémát összekapcsoló területről, azaz a szolgáltatások ellátási láncáról, ezen ellátási láncok kezelésének speciális problémáiról. Jelen műhelytanulmányban a szolgáltatások ellátási láncának és menedzsmentjének jellegzetességeit, a klasszikus terméket előállító ellátási láncokhoz viszonyított sajátosságait foglaltuk össze a nemzetközi szakirodalom alapján. Ennek során bemutattuk, hogy az ún. tiszta szolgáltatások széles körben ismert jellemzői hatással vannak a szolgáltatások előállítását és értékesítését végző ellátási láncok működésére is. Ezek a hatások és a specialitások megjelennek az ellátási lánc menedzsment irodalomban megjelenő mindhárom problémakörre, rányomják tehát bélyegüket mind az ellátási lánc felépítésére, struktúrájára, mind az ellátási láncban együttműködő partnerek kapcsolatának = In the last decades scholars have paid a lot of attention to both service operation and supply chain management. There is still limited research on the overlapping field of theses two management areas, on service supply chain specialties. This working paper gives a structured overview on the latest research results published in English. Doing so the paper would like to draw attention of the Hungarian researchers to this field and facilitate these empirical researches. As described in the paper traditional service specialties (intangibility, perishability, inseparability, heterogeneity and the importance of human capital) create special management problems concerning (i) the structure of these supply chains, (ii) their relationship management and (iii) the management of supply chain processes.

Az ellátási lánc menedzsmentje jól ismert és régóta tanulmányozott területe a menedzsment tudománynak. Jelen tanulmány célja, hogy egy olyan modell létezését igazolja, amely szerint egy ellátási láncban az információ menedzsmentje, az anyagi áramlások koordinációja és költségek és a teljesítmény kontrollja elengedhetetlen a teljes lánc magas szintű teljesítményéhez, és ezt a kockázatmenedzsment eszközök alkalmazásával tovább lehet növelni. Az ellátási lánc menedzsment eszközök támogatják a partnerek közötti információ megosztást (pl. EDI), az anyagi áramlások kisimítását (pl. folyamatos feltöltés, cross-docking). A költség és teljesítmény menedzsment eszközök alkalmazásának célja pedig hogy feltárják, hogy a költségek és hasznok miként oszlanak meg, merülnek fel az egyes ellátási lánc szereplők között. Ezeket az eszközöket akár vállalati, akár ellátási lánc szinten alkalmazzák, a végső cél a teljes ellátási lánc teljesítményének a növelése. Az ellátási lánc teljesítményét úgy határozzuk meg, mint az érték, amely a végső vevő számára keletkezett valamint a profit, amit az ellátási lánc partnerek realizáltak. Habár a vállalatok és az ellátási láncok különféle eszközöket alkalmazhatnak, hogy menedzseljék különböző folyamataikat, az a mód, ahogy szembenéznek a felmerülő kockázatokkal – fakadjanak akár a rendszerből magából, vagy a környezetből - és kezelik azokat, alapvető hatással bír a végső teljesítményre, így a versenyképességre is. A bemutatott kutatási modellel azt a kapcsolatot szeretnénk igazolni, amely feltevéseink szerint az ellátási láncban alkalmazott, a különféle alapfolyamatok menedzsmentjére valamint a kockázat menedzsmentjére használt eszközök és a realizált teljesítmény között van. _______ Supply chain management is a well-known and intensely studied field of management science. Our aim is to construct and test a model which summarises that besides the tools adapted to manage information flow, materials flow and costs and performance in supply chains to achieve high overall performance, managing risks is also inevitable. Supply chain management tools are to improve the efficiency of information sharing between supply chain participants (e.g. EDI) and to smooth materials flow carried out by the parties in collaboration (e.g. continuous replenishment, cross-docking). Cost management and performance assessment tools aim to explore the costs and profit realised by the cooperating companies as well as the entire supply chain. All the tools adapted either at a company or on supply chain level, strive to enhance the overall performance of the supply chain. The performance of a supply chain can be assessed by the value created for the end consumer and by the profit the partners realise. However, companies and supply chains adopt tools to manage the different flows, the way they face and handle risks coming either from the system or from the surrounding environment have a key influence on the performance achieved and consequently on competitiveness, too. When constructing the research model we try to find and verify the linkage between the tools supply chains use for coordination and for managing risks and the performance achieved.
